Florida Owner-Builder Permit Guide
By a retired general contractor with 15+ years building custom homes — about the author. Last updated: September 2026.
Florida presents unique challenges and opportunities for owner-builders. With mandatory statewide building codes driven by hurricane requirements, a clear contractor-licensing system, and significant regional variations, building your own home in the Sunshine State requires careful navigation. However, the state's strong owner-builder exemption and year-round building season make it very achievable.
Yes. Florida licenses residential general contractors through the DBPR, but Fla. Stat. § 489.103(7) gives property owners an owner-builder exemption: you can pull the permit and act as your own contractor on a one- or two-family home you own, as long as you provide direct, on-site supervision and don't offer it for sale or lease. You may even do your own electrical and plumbing on a home you'll occupy — but you may not hire an unlicensed person to do trade work for you. Selling or leasing within 1 year of completion creates a legal presumption you built it to sell, which voids the exemption. There is no square-footage or dollar cap on a one/two-family residence (the $75,000 cap applies only to commercial buildings).
| Work | Owner can DIY? | Rule |
|---|---|---|
| Act as your own general contractor | Yes | Fla. Stat. 489.103(7) owner-builder exemption; you must provide direct on-site supervision and sign the permit in person |
| Electrical wiring | Yes, on a home you own and occupy | Permitted under 489.103(7) and 489.503(6); permits and inspections still required. You may NOT pay an unlicensed person to do it |
| Plumbing | Yes, on a home you own and occupy | Permitted under the same owner-builder exemption; permits and inspections still required |
| HVAC, roofing, pool/spa | Yes if you do it yourself, otherwise license required | All three are licensed inside Part I of chapter 489, so the owner-builder exemption reaches them. If you hire it out, the contractor must be state-licensed |
| Septic system | Partly — you may install it, but you may not evaluate the site | Fla. Stat. 381.0065(4) exempts an owner who personally works on a system serving their own owner-occupied single-family residence from registration only, and leaves them subject to all permitting requirements. The site evaluation for a new system must come from one of five named credential-holders under Rule 62-6.004(3) |
| Private well | Rarely — the owner exemption covers 2-inch wells only | Fla. Stat. 373.326(2) exempts a well 2 inches or under in diameter on your own property. That is a driven well point, not the 4-6 inch cased well a household needs. The water management district permit is required either way |
| Sell or lease the home | Not within 1 year | Sale or lease within 1 year of completion presumes you built it for sale and voids the exemption |
Florida Building Code Overview
Florida enforces a single statewide building code, and it is newer than most people assume. State minimum-building-standards legislation goes back to the 1970s, but the unified Florida Building Code you actually build to today took effect in 2002 — the direct legislative answer to what Hurricane Andrew exposed in 1992 about a patchwork of local codes.
Current Code Adoption
As of 2026, Florida uses the 8th Edition (2023) Florida Building Code, which took effect December 31, 2023:
| Code | Edition / basis |
|---|---|
| Florida Building Code, Residential | 2023 (8th Edition), based on 2021 IRC |
| Florida Energy Conservation Code | 2023, based on 2021 IECC |
| National Electrical Code (NFPA 70) | 2020 as originally adopted via FBC Chapter 27; the Commission has since updated the referenced standard to the 2023 NEC — see the note below |
| Florida Plumbing Code | 2023 |
| Florida Mechanical Code | 2023 |
| Wind design standard | ASCE 7-22 (up from ASCE 7-16 in the prior edition) |
Do not be surprised when one document says 2020 NEC and another says 2023. Both are defensible right now. The 8th Edition as adopted referenced the 2020 NEC through FBC Building chapter 27. The Commission has since revised that referenced standard to the 2023 NEC, using a fast-track power the Legislature gave it specifically for the electrical code at Fla. Stat. § 553.73(8)(a)6. — the electrical code does not have to wait for the triennial cycle.
Ask your electrical plan reviewer which edition your permit will be reviewed against, and write down the answer with the date and the name of the person who gave it to you. Rough-in is a bad place to discover you guessed.
Update Cycle: Florida updates the code on a 3-year cycle, usually 1-2 years behind a new IRC release. The 9th Edition (2026) is in development, and that is all anyone can honestly tell you: the Building Commission's own code menu labels it a draft, a second comment period on glitch changes ran into the fall of 2026, and no effective date has been adopted. Fla. Stat. § 553.73(7)(e) separately requires an adopting rule to take effect no sooner than six months after the updated code is published. Treat any guide that hands you a firm 9th Edition enforcement date as guessing. Which edition applies to your project is set by your permit application date.
Florida-Specific Amendments
Florida's amendments are extensive, primarily driven by hurricane protection:
- Wind Load Requirements: Highest in nation (120-185 mph depending on location)
- High Velocity Hurricane Zones (HVHZ): Miami-Dade and Broward counties have even stricter requirements
- Roof Construction: Enhanced attachment requirements statewide
- Impact-Resistant Requirements: Windows/doors in many coastal areas
- Flood Protection: Strict BFE compliance in flood zones
- Termite Protection: Required statewide
- Pool Safety: Comprehensive barriers required for all pools
- Energy Code: Enhanced for hot, humid climate
- Product Approval: Products must have Florida Product Approval number
Local Amendments Expire on the Code Cycle
This is one of the genuinely reassuring facts about building in Florida, and almost nobody tells owner-builders about it. Your county can amend the code, but only in one direction and only for so long. Under Fla. Stat. § 553.73(4):
- Administrative amendments must be more stringent than the state code, and get transmitted to the Commission within 30 days
- Technical amendments come no more than once every 6 months, only after a hearing advertised 10 days ahead, only on evidence of a specific local need, only as stringent as that need requires — and they may not introduce a subject the state code does not address
- Wind resistance and water intrusion provisions may not be weakened at all, under § 553.73(7)(f)
- And the part worth remembering, § 553.73(4)(e): a local technical amendment "is effective only until the adoption of the new edition of the Florida Building Code by the commission every third year." At that point the Commission either adopts it statewide or it dies.
Practical effect: a local rule someone confidently tells you about at the lumber yard may have expired with the last code cycle. Ask the building department to point you at the currently adopted amendment, not a memory of one.
Florida Product Approval Is a Purchasing Constraint, Not Paperwork
Most guides file product approval under "paperwork." It is not paperwork. It decides what you are allowed to buy.
Fla. Stat. § 553.842(5) requires statewide approval for "panel walls, exterior doors, roofing, skylights, windows, shutters, impact protective systems, and structural components." At plan review you identify a Florida Product Approval number — an FL number — for every one of those on your house. You look them up in the Commission's own product approval search.
What that means on a Saturday at the supply house: a window with no Florida approval cannot be permitted here, no matter how well built it is or how much cheaper it is than the one next to it. Check the FL number before you buy, not after the truck arrives. This is the trap that catches owner-builders who order online, buy out of state, or take a deal on a cancelled order.
The trade is a real one, though. Under § 553.842(4), a statewide approval "shall preclude local jurisdictions from requiring further testing, evaluation, or submission of other evidence as a condition of using the product" when it is installed consistently with that approval. And if a building official rejects an approved product anyway, § 553.842(9) requires a signed written report stating the inconsistency — you are entitled to the reason in writing, not a shrug at the counter.
One practical warning: outside the HVHZ there is no single statewide "product approval schedule" form. The format is set locally. Ask your department for their template early, because assembling FL numbers for every exterior opening takes longer than anyone budgets for.
High Velocity Hurricane Zone (HVHZ)
Miami-Dade and Broward Counties have the nation's strictest residential building code:
- All products must pass Miami-Dade Protocol testing (missile impact, pressure cycling)
- "Miami-Dade Approved" label required on windows, doors, roofing, fasteners
- Significantly higher costs: +25-40% for materials
- More complex engineering requirements
- Longer permit review times
If building in HVHZ, budget extra time and money for compliance.
Florida Owner-Builder Laws
Florida licenses residential general contractors through the Department of Business and Professional Regulation (DBPR), but a clear statutory exemption lets you build your own home without a contractor license — with real strings attached.
Legal Rights
Under Fla. Stat. § 489.103(7), an owner of property "acting as their own contractor and providing direct, onsite supervision themselves of all work not performed by licensed contractors" may:
- Construct or improve a one-family or two-family residence (or a farm outbuilding) on property for their own occupancy or use
- Act as their own contractor without a state contractor license
- Perform the work themselves, or employ workers under their direct supervision
- Pull building permits as the owner-builder
There is no square-footage cap and no dollar cap on a one- or two-family residence under this exemption. The $75,000 cap in the statute applies only to commercial buildings — it does not limit your house.
Critical Restrictions
Own-Use / Not-For-Sale Requirement:
- The home must be for your own occupancy or use and not offered for sale or lease
- You cannot use the exemption to build spec homes or rentals for the market
- This is the core limit that separates an owner-builder from an unlicensed contractor
- Per the statute, if the home is sold or leased within 1 year after completion, the law presumes you built it for sale or lease — which violates the exemption
- This is the rule people call the "1-year rule." It is about not selling/leasing within a year, not a limit of one permit per year
- Plan to hold and occupy the home for at least a year after completion
Owner-Builder Disclosure Statement Required:
- You must read and sign the Owner-Builder Disclosure Statement required by § 489.103(7) when you apply for the permit
- You must personally appear and sign the building permit application
- It states, among other things, that you are legally and financially responsible for the construction, that it must comply with all applicable building codes, and that you may not hire an unlicensed person to act as your contractor or to supervise the work
- It also confirms that any unlicensed worker on your project must work under your direct supervision and be employed by you (meaning you must handle tax withholding and workers' compensation for them)
Lien Rights:
- As an owner-builder you are not entitled to the contractor's "Construction Industries Recovery Fund" protections, and you take on the contractor's legal responsibility
- Suppliers and subcontractors CAN file construction liens against your property
- Record a Notice of Commencement before work starts and collect lien releases as you pay. In Florida that document does double duty — it is also what gates your first inspection, which is why it gets its own section under Inspection Requirements below
Doing Your Own Trade Work
This is where most other guides get Florida wrong. The owner-builder exemption is broader than "you must hire licensed trades for everything."
You CAN do yourself (on a home you own and will occupy, with the required permits and inspections):
- General contracting / project management
- Framing, demolition, drywall, painting, flooring, cabinets, tile, finish carpentry, landscaping
- Electrical — § 489.103(7) covers "all work not performed by licensed contractors," and the electrical-contracting exemption in Fla. Stat. § 489.503(6) specifically lets an owner who is "supervising, and doing the work" act as their own electrical contractor on a single-family or duplex residence for their own use and occupancy, not for sale or lease
- Plumbing and mechanical/HVAC — same owner-builder logic applies when you personally do the work
You may not pay an unlicensed person to do this work for you. If you hire it out rather than doing it yourself, the electrician, plumber, HVAC, roofing, pool/spa, septic, and well contractors you hire must be state-licensed. You also cannot let an unlicensed "helper" run a trade as if they were the contractor — they have to be your supervised employee.
Trade contractor license types (when you do hire out):
| Trade | License type |
|---|---|
| Electrical | Certified/registered electrical contractor (EC/ER) |
| Plumbing | Plumbing contractor (CFC/RF) |
| HVAC | Mechanical contractor (CMC/CAC) |
| Roofing | Roofing contractor (CCC) |
| Pool/Spa | Pool/spa contractor (CPC) |
| Septic / wells | Licensed septic contractor / licensed water-well contractor |
Some building departments are stricter than the statute in practice and will scrutinize owner-performed electrical and plumbing closely at inspection, and a few require you to demonstrate competence. Inspectors apply the full code to your work regardless of who does it — verify your county's owner-builder trade policy before you plan to self-perform. When in doubt, a true general statement beats a costly assumption: confirm locally.
Contractor License Lookup
Verify all contractor licenses:
- Department of Business and Professional Regulation (DBPR): myfloridalicense.com
- Check status, disciplinary actions, insurance
- Required to provide license number before contracting
- Read whether the license is certified or registered. Under Fla. Stat. § 489.105(8) a certified contractor may contract anywhere in the state; under § 489.105(10) a registered contractor met one jurisdiction's local competency requirements and may contract only there. Seeing "Registered" is not the same as seeing a license that is good on your parcel
Permit Costs in Florida
Florida permit costs are among the highest in the nation, particularly in coastal counties.
The numbers below are illustrative planning ranges, not quoted fees. Florida sets permit fees locally, not by statute, and the schedules change on each jurisdiction's own timetable. These ranges are useful for sanity-checking whether a plan is in the right order of magnitude; they are not a substitute for your county's current published fee schedule. One statutory fact does help you: Fla. Stat. § 553.80(7) restricts permit fees to carrying out the local government's code-enforcement responsibilities, and gives an owner or builder holding a permit a civil action to enforce that. Ask for the published schedule and the methodology behind it.
Typical Fee Structure
Fees based on construction valuation (square footage x local multiplier):
| Fee | Basis / rate | Amount |
|---|---|---|
| Building permit | Construction value x fee rate; $5-$8 per $1,000 of construction value (varies by county) | Minimum $200-$500 |
| Plan review | Usually 65-80% of permit fee; separate line item in most counties | — |
| Electrical (if separate) | Trade permit | $100-$300 |
| Plumbing (if separate) | Trade permit | $100-$300 |
| Mechanical (if separate) | Trade permit | $100-$300 |
| Roofing (if separate) | Trade permit | $75-$200 |
County-Specific Examples
Estimates below are for a 2,000 sq ft home (Miami-Dade example assumes ~$400K construction value). They are illustrative planning figures compiled to show the spread between HVHZ, coastal, and inland counties — not quotes, and not tied to any schedule effective on a particular date.
| County | Building permit | Plan review | Other line items | Total permits |
|---|---|---|---|---|
| Miami-Dade (HVHZ) | ~$5,000 | ~$3,200 | Structural review ~$800; hurricane windstorm mitigation ~$400; technology surcharge $150; plus separate trade permits ~$600 | ~$9,550 permits (~$10,150 grand total with trade permits) |
| Broward (HVHZ) | ~$4,200 | ~$2,700 | Structural review ~$600 | ~$7,500 |
| Palm Beach | ~$3,200 | ~$2,100 | — | ~$5,300 |
| Orange (Orlando) | ~$2,800 | ~$1,800 | — | ~$4,600 |
| Lee (Fort Myers) | ~$2,600 | ~$1,700 | — | ~$4,300 |
| Polk (central FL, inland) | ~$2,200 | ~$1,400 | — | ~$3,600 |
| Escambia (Pensacola) | ~$2,400 | ~$1,500 | — | ~$3,900 |
Additional Fees
Total impact fees run $7,000-$30,000+ and vary dramatically by county/city. The ranges below are illustrative.
Two statutory facts are worth more than any range. Collection may not be required earlier than the date the building permit issues (Fla. Stat. § 163.31801(4)(e)) — so this is not a cost you carry through design. And a new or increased fee takes 90 days' notice and may not apply to permit applications submitted before its effective date, § 163.31801(4)(d). If your county has announced an increase, filing ahead of it locks the old rate. The same section requires every local government to publish its schedule and methodology, which is your path to a real number instead of a range.
| Impact fee category | Typical amount |
|---|---|
| Schools | $2,000-$8,000 |
| Roads | $1,000-$5,000 |
| Parks/Recreation | $500-$2,000 |
| Emergency Services | $500-$1,500 |
| Water/Sewer | $3,000-$10,000 |
| Total impact fees | $7,000-$30,000+ (varies dramatically by county/city) |
| Fee | Typical amount | Applies to |
|---|---|---|
| Address assignment | $25-$50 | — |
| Tree removal permit | $50-$200 per tree | Protected species |
| Environmental review | $200-$1,000 | Wetlands, endangered species |
| Archaeological review | $100-$500 | Some areas |
| Flood zone review | $200-$500 | — |
| Re-inspection fee | $50-$150 per failed inspection | After 2nd failure |
Processing Timelines
Florida timelines vary widely but are generally longer than most states due to strict requirements.
The County Is on a Statutory Clock, and Running Late Costs Them
Start here, because almost no owner-builder knows this clock exists and fewer still notice when it is missed. Fla. Stat. § 553.792 puts hard day counts on your local government:
- 30 business days to approve, approve with conditions, or deny a residential building permit where the structure is under 7,500 square feet. At or above that, 60 business days.
- 5 business days to tell you what your application is missing. Miss that window and the application is automatically deemed complete.
- Run past the review deadline and the permit fee is reduced 10% for every business day late.
- If a deficiency notice does go out, you get 10 business days to revise and the government gets 10 more to review — and on that second pass the penalty rises to 20% per business day.
Date-stamp your submittal and keep the receipt. Then count business days, not calendar days. You are not being difficult by asking, at day 31, whether the fee reduction applies — it is the statute's own remedy, and the reason it exists is that the alternative is an owner-builder with a construction loan accruing interest against a silent plan reviewer.
Cite § 553.792. Do not cite § 553.7921, which people confuse with it constantly — that one is the Uniform Fire Alarm Permit Application statute and has nothing to do with house permit timing.
Plan Review Timeline
The table below shows what jurisdictions actually run in practice, which is a different question from what the statute allows. These are illustrative observed ranges, not published service standards — ask your department what its current turnaround is.
| Jurisdiction type | First review | Resubmittal | Total to approval |
|---|---|---|---|
| HVHZ Counties (Miami-Dade, Broward) | 30-60 business days | 15-30 business days | 10-16 weeks typical (16-24 weeks for complex designs); structural review 20-40 business days, concurrent |
| Other Coastal Counties | 20-40 business days | 10-20 business days | 6-10 weeks |
| Inland Counties | 15-30 business days | 7-15 business days | 4-8 weeks |
Expedited Review (if available):
- Fee: +50-100% of review fee
- Timeline: Cut in half
- Not all counties offer this
You Can Hire Your Own Plan Reviewer and Inspector
Florida is one of the few states that lets you go around the queue entirely, and it is badly underused by owner-builders. Under Fla. Stat. § 553.791 you may retain a private provider — a licensed building code administrator, engineer, or architect — to do your plan review, your inspections, or both.
- You give notice in writing at permit application, or by 2:00 p.m. two business days before the first inspection you want the private provider to handle.
- The local jurisdiction "must reduce the permit fee by the amount of cost savings" and "may not charge fees for building inspections" it is no longer performing. You are not paying twice.
- Deemed-approved windows are short: 20 business days generally, 10 if an engineer or architect sealed the affidavit, and 5 for a single-trade review on a one- or two-family dwelling.
- Certificate of occupancy in 2 business days for a one- or two-family dwelling.
The trade is straightforward: you are paying a private professional instead of waiting on a public one. On a build where the construction loan is accruing and the county is quoting 10 to 16 weeks, run that arithmetic before you assume the county route is cheaper. Note that a private provider is bound by the same Notice of Commencement gate the building department is — § 713.135(1)(e)1. names private providers explicitly.
Permit Issuance
Once approved:
- Issuance: 1-5 business days
- Some counties: same-day pickup
Permit Validity
Here is a rule almost every Florida guide gets wrong, including this one until this update. Permit life is not in the statutes. It lives in the administrative chapter of the FBC Building volume, which means it is also administratively amendable by your local government — so confirm the numbers below with your department rather than assuming the state-level version governs your parcel.
- Application abandoned at 180 days — FBC Building 105.3.2. An application that sits without action dies before the permit ever issues.
- Permit invalid if work is not commenced within 6 months, or if work is suspended or abandoned for 6 months — 105.4.1.
- And the one that actually saves owner-builders, 105.4.1.3: "Work shall be considered to be in active progress when the permit has received an approved inspection within 180 days."
That last line is the whole game for anyone building part-time. You do not have to finish on a schedule. You have to keep passing an inspection inside every 180-day window. Plan your inspection sequence so no gap runs long — a slow stretch waiting on cabinets or a subcontractor is exactly when a permit quietly lapses, and re-permitting a partly built house is far worse than scheduling one inspection you could have taken earlier.
Hurricane and Wind Requirements
Hurricane and wind requirements are the single biggest driver of Florida's construction cost and complexity.
Wind Speed Design Requirements
Florida uses Ultimate Wind Speed (3-second gust), and this guide deliberately does not print a county-by-county wind speed table.
Here is why. The 8th Edition moved wind design to ASCE 7-22, and ASCE 7-22 works from a location-specific geodatabase rather than the broad contour map people are used to reading off. A regional table gets you a number that is close, and close is the worst possible outcome — design to 150 mph on a parcel that calls for 160 and you will find out at plan review, after the trusses are engineered.
Look up your actual parcel. The ASCE Hazard Tool (ascehazardtool.org) returns the design wind speed for a specific latitude and longitude under ASCE 7-22, which is the standard the code now points to. Then confirm the number with your building department in writing before your engineer designs to it. Two minutes of lookup, and it is the single input the rest of your structural package is built on.
Do not assume "inland" means "not windborne debris region." The 8th Edition revised the first limb of the windborne debris region definition — deleting the word coastal and framing the test around an Exposure D condition upwind of the water line. The practical consequence, in DBPR's own words describing the change, is that some inland areas near large bodies of water can now fall inside the windborne debris region where the design wind speed is high enough.
If you are building on a lake with a long fetch, get your parcel's windborne debris status confirmed in writing before you price windows. The difference between opening protection required and not required is tens of thousands of dollars.
Hurricane Construction Requirements
Roof System:
- Enhanced shingle attachment (6-8 nails per shingle vs. 4 standard)
- Ring-shank nails for sheathing (8d vs. 6d standard)
- Hurricane straps/clips at every rafter connection
- Continuous load path from roof to foundation
- Gable end bracing
- Soffit/fascia attachments rated for wind pressure
Windows and Doors — and this is a cost lever most guides quietly close for you:
- Inside the windborne debris region, openings must be protected. What the code requires is opening protection, not impact glass specifically.
- Impact-resistant glazing OR approved shutters both satisfy FBC Residential R301.2.1.2. This is true in Miami-Dade too — the widely repeated claim that impact glass is mandatory in Miami-Dade is wrong. Products there must meet the Miami-Dade protocols, but shutters that meet them are an option.
- Protection is qualified by the Large Missile Test of ASTM E1996/E1886, or TAS 201/202/203, or AAMA 506; garage door glazing under ANSI/DASMA 115 or another approved standard.
- The code even keeps a plywood option: 7/16-inch wood structural panels, precut, predrilled, with permanently installed corrosion-resistant hardware, where mean roof height is 33 feet or less and the ultimate design wind speed is 180 mph or less.
The reason this matters: on a whole-house basis the spread between impact windows and shuttered standard windows is commonly tens of thousands of dollars. You may still want impact glass — no pre-storm labor, insurance credit, better acoustics — but that should be your decision made against real numbers, not something you were told was mandatory.
Garage Doors:
- Must be wind-rated for design pressure
- Reinforcement required in many areas
- Impact rating required in some coastal areas
Roof Covering:
- Must have Florida Product Approval
- Impact resistance ratings (Class 3-4 in some areas)
- Underlayment: Enhanced in coastal areas
Wall Bracing:
- Continuous shear bracing
- Higher nailing schedules
- Properly blocked let-in bracing or structural sheathing
Cost Impact
Hurricane requirements add significantly to costs:
| Location | Added % of construction cost | Added cost on 2,000 sq ft home |
|---|---|---|
| HVHZ (Miami-Dade/Broward) | +25-40% | +$75,000-$120,000 |
| Other coastal counties | +15-25% | +$45,000-$75,000 |
| Inland counties | +5-10% | +$15,000-$30,000 |
Energy Code Requirements
Florida's hot, humid climate drives specific energy requirements.
2023 Florida Energy Conservation Code
Climate Zone: All of Florida is Climate Zone 1A (hot-humid)
Do not go looking for a single table of R-values to build to. Florida gives you three compliance paths, and which one you pick changes which numbers apply to your house — a prescriptive R-value that is mandatory on one path is irrelevant on another. Pick the path first, then get the numbers from the code book or your rater.
| Path | Section | How it works |
|---|---|---|
| Prescriptive | R402 | Meet the listed envelope values component by component. Documented on Form R402-2023, which now carries SEER2/HSPF2 equipment labeling |
| Performance (simulated energy) | R405 | Model the whole house against a reference design using Commission-approved software. The 8th Edition tightened the maximum total e-Ratio from 1.00 to 0.95. There is no static Form R405 PDF — the submittal is the software output |
| Energy Rating Index | R406 | Comply against an ERI target instead of the prescriptive envelope |
Every path also requires Form R400-2023, the Residential Energy Conservation Code Documentation Checklist. Get all of these from the Building Commission's own forms and code pages — not from a national energy-code site, which will hand you the wrong document.
FBC Energy Conservation R402.4.1.2 sets the maximum at 7 air changes per hour at 50 pascals in Florida's climate zones — not 5, which is the figure that circulates in most Florida guides and is simply wrong.
Two things that follow from it, both of which surprise owner-builders:
- Go below 3 ACH50 and the code then requires whole-house mechanical ventilation. Building an unusually tight house is not a free win here; it adds a system. Decide that deliberately, not by accident.
- The test may not be self-certified. It has to be run by an energy auditor or rater, a Class A or B air-conditioning or mechanical contractor, or a third party your code official approves. The test happens after envelope penetrations are sealed. Line up the tester early — this is a common source of last-minute delay before the final.
Duct Testing: duct leakage testing is required and is typically performed with the blower door by the same rater. The specific leakage threshold moves between code editions and paths, so ask your rater or plan reviewer for the figure that applies to your permit rather than trusting a number from a guide. Budget roughly $300-$500 for the testing, illustratively.
Cool Roof Requirements (some jurisdictions):
- Solar reflectance index (SRI) requirements
- Light-colored roofing preferred
- Reduces cooling loads significantly
Florida-Specific Energy Strategies
Critical for Florida:
- High-efficiency AC: check the rating system before you shop. Florida's current energy forms are written in SEER2 and HSPF2, not the older SEER and HSPF. A SEER2 number is not the same as the SEER number on an older spec sheet, so a "14 SEER" figure from a pre-2023 guide will not match what your Form R402-2023 asks for. Get the minimum that applies to your permit from your HVAC contractor or rater, then buy above it — cooling runs most of the year here and the payback is real
- Dehumidification: Separate dehumidification or AC with dehumidification mode
- Radiant Barrier: Required in attic in some counties, highly recommended everywhere
- Proper Ventilation: Ridge and soffit vents essential
- Low-E Windows: East and west exposures critical
- Overhangs: Shade windows from direct sun (especially south)
- AC runs 8-12 months in Florida
- Every $1 spent on better insulation/windows saves $3-5 in energy over 10 years
- Don't skimp on energy efficiency
Flood Zone Requirements
Flood zone status is a critical consideration — much of Florida sits within mapped flood zones.
Flood Zone Designations
| Risk level | Zone | Description |
|---|---|---|
| High-Risk (Special Flood Hazard Areas) | Zone AE/A | High risk, Base Flood Elevation (BFE) determined |
| High-Risk (Special Flood Hazard Areas) | Zone VE/V | High risk coastal, wave action (most restrictive) |
| Moderate/Low Risk | Zone X (shaded) | 0.2% annual chance |
| Moderate/Low Risk | Zone X (unshaded) | Minimal risk |
Building in Flood Zones
Zone AE Requirements:
- Lowest floor must be at or above BFE
- Many jurisdictions require BFE + 1 foot (freeboard)
- Crawl space or elevated slab required
- Flood vents required in foundation walls

The Coastal Construction Control Line: A Second Permit From a Second Agency
If your lot is anywhere near the beach, this is the item that can stop a project cold, and it is missing from most Florida owner-builder guides entirely.
Construction seaward of the coastal construction control line (CCCL) requires a separate permit from the Florida Department of Environmental Protection, under Fla. Stat. § 161.053 and Rule 62B-33, F.A.C. This is not a step inside your building permit and it is not something your county handles for you. It is an independent state permit from a different agency, on its own timeline. DEP publishes the line and its program materials on the coastal construction control line page.
Three things to understand before you buy a coastal lot:
- The 30-year erosion projection can bar the permit outright. Section 161.053(5)(b) prohibits a permit for a structure proposed for a location that will be seaward of the seasonal high-water line within 30 years of the application date. There is a narrow exception at § 161.053(5)(c) for certain pre-existing platted single-family lots. A lot can be legally subdivided, taxed, and for sale, and still be unbuildable under this test.
- Some local governments run their own coastal program "in lieu of" the state process, under DEP oversight (§ 161.053(3)). Find out which applies to your parcel before you file anything.
- The coastal building zone is a different and much larger area. Under § 161.54(1) it runs from the seasonal high-water line to 1,500 feet landward of the CCCL — and on coastal barrier islands, 5,000 feet landward or the entire island, whichever is less. All of Monroe County is included. Being in the coastal building zone triggers the § 161.55 construction standards; it does not by itself require the separate DEP permit. Two different lines, two different consequences — confirm which one your lot sits behind.
Inspection Requirements
Plan for a full inspection schedule from foundation through final certificate of occupancy.
The Notice of Commencement: A Courthouse Filing That Gates Your First Inspection
If you read only one section of this guide, read this one. The Notice of Commencement is filed at the clerk of the circuit court, not the building department, which is exactly why owner-builders miss it — it is not on the counter with everything else, and nobody at the permit desk is required to remind you.
Here is what it controls. Under Fla. Stat. § 713.135(1)(e)1.:
"In the absence of the filing of a copy of the notice of commencement, the issuing authority or a private provider performing inspection services may not perform or approve subsequent inspections until the applicant files… such copy with the issuing authority."
Note who that binds: the building department and a private provider. Hiring your own inspector does not get you around it.
But the permit itself is not held up by it. Sections 713.135(1)(f) and (1)(e)4. bar the department from requiring the recorded notice as a condition of applying for, processing, or issuing the permit. So the sequence is: permit can issue, then the notice gates the inspections. People conflate these two halves constantly and end up either filing far too early or discovering the problem at footing inspection.
Three different dollar thresholds apply, and they are not the same number:
| Threshold | What it triggers | Citation |
|---|---|---|
| Over $2,500 | Recording the Notice of Commencement is required at all | Fla. Stat. 713.02(5) — note this lives here, not in 713.13 |
| Over $5,000 | A copy must be filed with the building department before the first inspection | Fla. Stat. 713.135(1)(e) |
| Under $15,000 | HVAC repair or replacement contracts are carved out of 713.135(1) entirely | Fla. Stat. 713.135(1) |
The mechanics, and the two clocks inside them:
- Record it before you commence work (§ 713.13(1)(a)), then post a certified copy or a notarized statement at the job site.
- You sign it personally. Section 713.13(1)(g) says "no one else may be permitted to sign in his or her stead." It is sworn, so the form carries a notary block — Florida does permit online notarization.
- Void if work does not begin within 90 days of recording (§ 713.13(2)). Record too early and it expires before you break ground.
- Effective for 1 year from recording unless the notice states otherwise (§ 713.13(6)). You can amend it to extend, but changing contractors requires a new notice.
- Payments made after it expires are "improper payments." The statutory form's own WARNING TO OWNER says they "CAN RESULT IN YOUR PAYING TWICE." On a build that runs past a year — and part-time owner-builder projects routinely do — this is not a paperwork problem, it is a paying-for-your-framing-twice problem. Diary the expiration date the day you record it.
As your own contractor, the lien documents that normally flow from a general contractor to an owner have nobody to flow from. Nobody is going to hand you a Notice of Commencement to sign, chase your lien releases, or produce a final payment affidavit. Every one of those jobs is now yours, on top of building the house.
The 90-day and 1-year clocks above are the two most commonly blown. Put both on a calendar the day you record.
Minimum Required Inspections
| # | Inspection | Timing / condition |
|---|---|---|
| 1 | Building Slab/Monolithic Pour | Before pouring |
| 2 | Building Footing/Stem Wall | Before pouring |
| 3 | Building Foundation | After foundation complete |
| 4 | Electrical Underground | Before covering |
| 5 | Plumbing Underground | Before covering, must pressure test |
| 6 | Building Frame | After framing complete |
| 7 | Structural Frame | Engineered elements — trusses, beams, connectors — checked against the sealed truss package and the engineer of record's plans |
| 8 | Electrical Rough-In | Before insulation/drywall |
| 9 | Plumbing Rough-In | Before covering, must pressure test |
| 10 | Mechanical Rough-In | Before covering |
| 11 | Insulation | After installation, before drywall |
| 12 | Gas Test | If gas lines installed |
| 13 | Truss Bracing | During framing (some counties) |
| 14 | Sheathing Nailing | During roof/wall sheathing (spot checks) |
| 15 | Final Building | All work complete |
| 16 | Final Electrical | All devices installed, power on |
| 17 | Final Plumbing | All fixtures installed, tested |
| 18 | Final Mechanical | HVAC operational, tested |
| 19 | Energy Final | Duct testing, blower door (if required) |
A persistent piece of bad advice tells Florida owner-builders they must hire a special inspector once their frame is engineered. That is not the law for a one- or two-family dwelling.
The special-inspector regime attaches to threshold buildings, defined at Fla. Stat. § 553.71(12) as buildings greater than three stories or 50 feet in height, or assembly occupancies over 5,000 square feet holding more than 500 occupants. A house never qualifies. Your structural frame is inspected by the building department like everything else.
Your engineer of record may still want to see the frame, and your truss supplier's engineering has to be on site — but that is a design-team question, not a statutory special-inspector requirement, and it should not appear as a line item in someone's quote to you.
Additional Inspections (as needed)
- Pool/Spa: Multiple inspections (steel, gunite, plaster, barrier)
- Seawall: If waterfront property
- Hurricane Protection: the building official schedules an inspection to confirm the impact-resistant coverings or systems on your plans were installed per the manufacturer's instructions and per the product approval — this is where your FL numbers get checked against what is actually hanging in the wall
- Elevations (flood hazard areas): two separate certifications, not one — an elevation certification upon placement of the lowest floor, before further vertical construction, and a final certification at the final inspection. Getting the first one late stops the job
Inspection Scheduling
- Most counties: Online scheduling (24-48 hours advance)
- Call-in scheduling still exists in some rural counties
- Inspection windows: Usually 8am-12pm or 12pm-4pm
- Must be present for most inspections
- Failed inspection: 24-48 hour delay for re-inspection
Common Inspection Failures
- Improper hurricane straps/clips
- Incorrect nailing patterns on sheathing
- Missing blocking or headers
- Improper plumbing vents
- GFCI outlets missing (required in many locations)
- Handrail height incorrect
- Smoke detector placement wrong
- Missing flood vents (flood zones)
Special Florida Considerations
Termites and Pests
Termite pressure in Florida is serious — take it seriously and budget for it.
Pre-Treatment Required:
- Chemical soil treatment before slab pour
- Licensed pest control operator
- Cost: $700-$1,500
- Warranty: Usually 1 year included
Post-Treatment Recommended:
- Annual inspections: $75-$150
- Bait stations: $600-$1,200 initial, $300-$500 annually
- Treatment if active: $1,200-$3,000+
Building Strategies:
- Pressure-treated lumber for all plates on slab
- Avoid wood-to-ground contact
- Proper drainage (termites love moisture)
- Physical barriers (stainless mesh) in high-risk areas
Septic Systems
Much of Florida is on septic, and on a rural lot the septic permit is not a side errand — it is the first domino.
Because the water table drives so much of the layout here, it pays to draw the lot first: the free Site Plan Studio places the well, tank and drainfield to scale, measures the distance between them, and prints a letter-size sheet for your septic application.
This one statute reorders your entire filing sequence, and it is missing from nearly every Florida owner-builder guide. Fla. Stat. § 381.0065(4) says a municipality or political subdivision:
"may not issue a building or plumbing permit for any building that requires the use of an onsite sewage treatment and disposal system unless the owner or builder has received a construction permit for such system from the department. A building or structure may not be occupied and a municipality, political subdivision, or any state or federal agency may not authorize occupancy until the department approves the final installation…"
Read that twice. Septic construction permit before building permit. Septic final approval before occupancy. Both are statutory, neither is discretionary, and the permit office will simply enforce both without explaining why.
On a rural lot the practical order is: site evaluation, then septic construction permit, then building permit application. If you plan a spring start and book the site evaluation for March, you have already lost the season.
Who Actually Issues Your Septic Permit — the Answer Is Split
Most guides get this wrong in one direction or the other, and both common answers are wrong for a large part of the state.
The onsite sewage program transferred from the Department of Health to the Department of Environmental Protection effective 1 July 2021, under the Clean Waterways Act (ch. 2020-150, Laws of Florida). The rule chapter was renumbered from 64E-6 to 62-6, F.A.C. in the same move, which is why county forms and older handouts still say 64E-6.
But the transfer is phased and it is not finished.
- DEP issues permits directly in 17 counties: Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, Jefferson, Leon, Liberty, Marion, Okaloosa, Santa Rosa, Wakulla, Walton, and Washington.
- In the other 50 counties — including every major metro — you still file with the Environmental Health program of your county health department.
DEP's own onsite sewage permitting FAQ says the remaining transitions depend on legislative approval, and publishes no schedule. So "the health department regulates septic" is out of date, and "DEP regulates septic" is misleading for 50 of the 67 counties. Check which office covers your county before you file, and check again if your project spans a year.
| System type | Cost | Notes |
|---|---|---|
| Conventional | — | Still the norm on ordinary lots. Enhanced nutrient-reducing systems are required in specific designated areas such as BMAP and impaired-basin areas, not statewide |
| Aerobic Treatment Unit (ATU) | $8,000-$15,000 | Common where an advanced system is required or where site conditions demand one |
| Performance-Based | $12,000-$25,000 | Advanced systems, engineered to a performance standard |
Site Evaluation — and note who is allowed to do it:
- Required first step; illustratively $400-$800
- Soil testing and wet-season water table evaluation. A high water table is common in Florida, and it is why filled and mound systems are so often the answer
- You cannot self-perform this one. Rule 62-6.004(3) limits the site evaluation for a new system to five credential-holders: a Florida licensed engineer with soils training, department personnel, a Master Septic Tank Contractor, a certified professional soil scientist, or a person certified under § 381.0101
Permits and Timeline:
- Permit: illustratively $400-$1,000
- Timeline: roughly 6-10 weeks from evaluation to final approval — build this into the front of your schedule, not the middle
- You may install it yourself, within limits. Section 381.0065(4) exempts "a property owner who personally performs construction, maintenance, or repairs to a system serving his or her own owner-occupied single-family residence" from registration requirements only — and expressly leaves that owner "subject to all permitting requirements." Read the conditions literally: personally, your own, owner-occupied, single-family. Anyone you pay to install it must be a registered septic contractor
Maintenance:
- ATU and performance-based systems carry operating permits and maintenance contracts, illustratively $200-$400/year
- An ordinary residential gravity system outside a BMAP or impacted area generally does not require an operating permit
- Pumping: every 3-5 years, illustratively $300-$500
Wells
Common in rural Florida areas — and a different agency again. Well permits come from one of the five water management districts under Rule 62-532, F.A.C. and each district's own chapter, not from the county and not from DEP's septic program.
Requirements:
- A permit is required before construction, repair, or abandonment, applied for by the owner or by the water well contractor on the owner's behalf (Rule 62-532.400(1)). Illustratively $200-$500
- Practically, you will hire a licensed driller. The owner exemption at Fla. Stat. § 373.326(2) is much narrower than people assume: it reaches a well "2 inches or under in diameter" on your own or leased property for a single-family house that is your residence. That describes a driven well point, not the 4-6 inch cased well a household needs. And it is an exemption from licensure only — the district permit still applies
- Setback from septic: 75 feet minimum for a private potable well, Rule 62-6.005(1)(a)
- Depth: 100-800 feet, varies by region
- Cost: illustratively $3,500-$15,000
- Water testing: Florida's rules do not mandate a bacteriological test before occupancy for a true single-family private well — the testing regime in Rule 64E-8.003(5) is scoped to multifamily and limited-use public systems. Your lender or title company will very likely require one anyway. That is a lending requirement, not a state rule, and it is worth knowing which one you are satisfying. Budget $150-$300 either way
Water Quality Issues:
- High sulfur common (rotten egg smell)
- High iron common (staining)
- Saltwater intrusion in coastal areas
- May need treatment: $2,000-$8,000
Sinkholes
High-risk areas:
- Central Florida (Pasco, Hernando, Hillsborough)
- Parts of north-central Florida
Considerations:
- Geological survey recommended before purchase
- Sinkhole insurance expensive
- Foundation design may need engineering
Hurricane Shutters vs. Impact Windows
| Option | Pros | Cons | Cost / notes |
|---|---|---|---|
| Impact Windows | Permanent, no prep, insurance discount, noise reduction, UV protection | Expensive | $40,000-$80,000 for typical home; required in HVHZ |
| Hurricane Shutters | Less expensive, effective | Must install before storm, storage issues, labor-intensive | $8,000-$25,000; types: panels, accordion, roll-down (roll-down most expensive) |

This is the source of record for anything about the code; check it before you believe a summary anywhere else.
Department of Business and Professional Regulation (DBPR) — contractor license verification, complaints, and the licensing rules behind chapter 489. Verify every license here before you sign anything, and read the certified versus registered distinction: a registered contractor may contract only in the jurisdictions where they met local competency requirements, so seeing "Registered" does not mean the license is good on your parcel.

Florida Administrative Code — the rules, including septic (chapter 62-6), wells (62-532), and the coastal construction control line (62B-33). Rule chapter 62-6 has been amended repeatedly and moves faster than most; check the effective date on any rule you rely on.
Septic — and check which office covers your county. Florida DEP's onsite sewage program issues permits directly in 17 counties; in the other 50 you file with your county health department's Environmental Health program. The permitting FAQ is where DEP publishes the current split. Note that drinking-water quality rules stayed with the Department of Health — only the onsite sewage program moved.
County Building Departments
A note on how these are listed. When the obvious deep permitting URLs for thirty Florida counties were tested for this update, eleven were dead or silently redirected somewhere unrelated — several counties use reassignable numeric page IDs, and one "building department" link resolved to a stormwater master plan. So this guide gives you root domains and lets you search from there. It is one extra click and it will still work next year.

Common Questions from Florida Owner-Builders
Q: Is owner-building more expensive in Florida due to licensing requirements? A: You'll spend more on licensed contractors, but can still save 15-25% overall by managing the project, doing finish work, and sourcing materials yourself. HVHZ areas: savings closer to 10-15%.
Q: Can I get financing as owner-builder in Florida? A: Yes, but challenging. Look for:
- Local credit unions
- USDA loans (rural areas)
- Smaller regional banks
- Owner-builder specific lenders
- Expect 20-25% down, higher rates
Q: How much does hurricane code really add to costs? A: Illustratively — HVHZ (Miami-Dade/Broward): +$50,000-$100,000 on a typical home. Other coastal: +$30,000-$60,000. Inland: +$10,000-$25,000. You get insurance discounts and storm protection in return. One lever people give away for free: opening protection can be satisfied by approved shutters rather than impact glass, including in Miami-Dade, and on a whole house that difference is real money.
Q: Should I build in a flood zone? A: Only if you understand costs. Zone AE: manageable (+$15,000-$35,000). Zone VE: expensive (+$50,000-$150,000). Factor in flood insurance ($1,000-$5,000/year). Consider higher ground if available.
Q: Can I DIY any major work? A: More than most guides claim. On a home you own and will occupy, the owner-builder exemption (Fla. Stat. 489.103(7)) lets you do your own:
- General contracting and project management
- Framing, drywall, finish carpentry, painting, flooring, tile, cabinets
- Electrical and plumbing (489.103(7) plus the electrical owner exemption in 489.503(6)) — with permits and inspections The catch: you may not pay an unlicensed person to do this work. Anything you hire out — electrical, plumbing, HVAC, roofing, pools, septic, wells — must go to a state-licensed contractor. Some building departments scrutinize owner-performed trade work closely, so confirm your county's policy before planning to self-perform.
Q: What's the biggest mistake Florida owner-builders make? A: Two, and they are both sequencing mistakes rather than construction ones.
The first is underestimating hurricane code cost and timeline. Get detailed quotes early, plan for longer reviews in coastal counties, and don't cut corners on wind protection — it will fail inspection and cost more to fix than to do right.
The second is treating Florida's gates as paperwork you handle later. On a rural lot the septic construction permit has to exist before the building permit can issue (§ 381.0065(4)), and the Notice of Commencement has to be recorded at the courthouse and filed with the department before anyone will inspect you (§ 713.135(1)(e)1.). Neither is optional, neither is on the building department's counter, and both stop the job dead when they're missed. Handle them in month one.
Q: Who issues my septic permit — the health department or DEP? A: Depends on your county, which is why most guides get this wrong. The onsite sewage program transferred from the Department of Health to DEP effective 1 July 2021 under the Clean Waterways Act, but the transfer is phased and unfinished. DEP issues directly in 17 counties; in the other 50 — including every major metro — you file with your county health department's Environmental Health program. Check the current split on DEP's permitting FAQ before you file.
Florida Owner-Builder Timeline Example
Timeline for 2,000 sq ft home in coastal county (not HVHZ).
| Phase | Tasks and durations |
|---|---|
| Months 1-3: Planning & Permitting | Land purchase: 2-8 weeks; septic site evaluation and construction permit: 6-10 weeks, and it must come FIRST because the building permit cannot issue without it; plans (with engineering): 4-8 weeks; record the Notice of Commencement before work starts; permit submittal and review: 6-10 weeks; impact fees and permit issuance: 1 week |
| Month 3-4: Site Work | Clear and rough grade: 1 week; septic installation: 2-3 weeks; well drilling: 1-3 weeks; driveway: 1 week; temporary power: 1-2 weeks |
| Month 4-5: Foundation | Layout: 2-3 days; plumbing under slab: 3-5 days; foundation forms and pour: 1-2 weeks; cure: 1 week |
| Month 5-7: Framing | Frame walls: 2-4 weeks; frame roof with hurricane ties: 2-3 weeks; sheathing with enhanced nailing: 1-2 weeks; windows and doors (impact-rated): 1-2 weeks |
| Month 7-8: Exterior | Roofing (enhanced attachment): 2-3 weeks; siding: 2-3 weeks |
| Month 8-10: Mechanicals | Electrical rough-in (licensed contractor or owner-performed): 1-2 weeks; plumbing rough-in (licensed contractor or owner-performed): 1-2 weeks; HVAC rough-in (licensed contractor or owner-performed): 1-2 weeks; inspections and corrections: 1-2 weeks |
| Month 10-12: Insulation & Drywall | Insulation: 1 week; drywall: 3-4 weeks; paint: 2-3 weeks |
| Month 12-14: Finishes | Cabinets and counters: 2-3 weeks; flooring: 2-3 weeks; trim: 2-3 weeks; final electrical/plumbing (licensed contractor or owner-performed): 2 weeks |
| Month 14-15: Final | Exterior finishing: 1-2 weeks; final inspections: 1-2 weeks; punch list: 1-2 weeks; Certificate of Occupancy |
Total: 14-15 months (part-time owner-builder)
HVHZ areas: Add 2-4 months for longer permit review and more complex construction.
The schedule above only holds if materials arrive on time — see the material lead times guide for when to order windows, trusses, and cabinets (impact-rated windows run even longer). And in the finish stage, installing your own interior trim is one of the easiest places to cut labor costs.
Final Thoughts for Florida Owner-Builders
Florida's combination of strict building codes and a strong owner-builder exemption creates a unique environment. You have the legal right to build your own home — and even to do your own electrical and plumbing on a home you'll occupy — but anything you hire out must go to a licensed professional. The key to success:
- Budget for hurricane requirements - They're expensive but non-negotiable and protect your investment
- Use licensed trades when you hire out - You can self-perform under the exemption, but you can't pay unlicensed help; for most owner-builders, licensed electricians, plumbers, and HVAC techs are worth it for the expertise and inspection sign-off
- Respect the gates, and handle them first - the septic construction permit before the building permit, the Notice of Commencement before the first inspection. Neither is on the building department's counter and both stop the job cold
- Plan for longer timelines - permit reviews take months in many counties. Know that § 553.792 puts the county on a clock, and that § 553.791 lets you hire your own plan reviewer and inspector if waiting is costing you more than paying
- Check flood zones, and the coastal control line - flood zone status can add $50,000+; a lot seaward of the CCCL needs a separate state permit and may fail the 30-year erosion test outright
- Focus on energy efficiency - AC runs most of the year, good ROI
- Don't fight the code - Florida's requirements are there for good reasons (Hurricane Andrew taught hard lessons)
Whether building in the panhandle, central Florida, or south Florida, respect the climate, follow the code, and build for the long term. Your home will withstand hurricanes that would destroy standard construction, and that peace of mind is priceless.
Florida Owner-Builder FAQs
Can you build your own house in Florida without a license?
Yes. Florida licenses residential general contractors through the DBPR, but Fla. Stat. 489.103(7) gives property owners an owner-builder exemption. You can pull the permit and act as your own contractor on a one- or two-family home you own, as long as you provide direct on-site supervision, sign the permit in person, and do not offer the home for sale or lease. There is no square-footage or dollar cap on a one/two-family residence; the $75,000 cap in the statute applies only to commercial buildings.
Do you need a contractor's license to build your own home in Florida?
No. Under the owner-builder exemption you do not need a state contractor license to build your own primary residence. You take on the contractor's legal and financial responsibility, you must sign the Owner-Builder Disclosure Statement at permit application, and you cannot hire an unlicensed person to act as your contractor. If you sell or lease the home within one year of completion, the law presumes you built it for sale, which voids the exemption.
Can a homeowner do their own electrical and plumbing work in Florida?
Yes, on a home you own and occupy — but under two different exemptions, because chapter 489 is split. Plumbing, mechanical, air-conditioning and roofing are all licensed inside Part I, and Fla. Stat. 489.103 opens by saying this part does not apply to owners acting as their own contractor, so when Part I stops applying to you it stops applying for those trades. Electrical is licensed separately under Part II, which is exactly why it needs its own exemption at Fla. Stat. 489.503(6) with its own disclosure statement. Permits and inspections are still required either way. On the electrical code edition, ask your plan reviewer: the 8th Edition as adopted referenced the 2020 NEC, and the Commission has since updated the referenced standard to the 2023 NEC using a fast-track power that applies only to the electrical code. The key limit: you may not pay an unlicensed person to do the work for you. Some building departments scrutinize owner-performed trade work, so confirm your county's policy first.
What is the Florida owner-builder one-year rule?
Under Fla. Stat. 489.103(7), if you sell or lease an owner-built home within one year after construction is complete, the law presumes you built it for sale or lease, which violates the exemption and can expose you to unlicensed-contracting penalties. It is not a limit of one permit per year; it is a hold-and-occupy rule. Plan to keep and occupy the home for at least a year after completion.
Which Florida Building Code is in effect in 2026?
Florida is on the 8th Edition (2023) Florida Building Code, effective December 31, 2023. The Residential volume is based on the 2021 IRC, the Energy Conservation volume on the 2021 IECC, and wind design moved to ASCE 7-22 in this edition. The 9th Edition (2026) exists only as a draft on the Building Commission's own code menu, with no adopted effective date — treat any guide that gives you one as guessing, since Fla. Stat. 553.73(7)(e) also requires the adopting rule to take effect no sooner than six months after the updated code is published. The electrical answer is genuinely split: the 8th Edition as adopted referenced the 2020 NEC through FBC Chapter 27, and the Commission has since updated that referenced standard to the 2023 NEC under a fast-track power specific to the electrical code. Ask your electrical plan reviewer which edition your permit is reviewed against. Which edition applies to your project overall is set by your permit application date.
Do I need a Notice of Commencement in Florida?
For a house, yes — and the sequencing matters more than the form. You record it with the clerk of the circuit court before commencing work, post a certified copy or notarized statement at the site, and file a copy with the building department before the first inspection. Until that copy is filed, Fla. Stat. 713.135(1)(e)1. bars the building department or a private provider from performing or approving inspections. But the same statute bars the department from requiring it as a condition of issuing the permit, so the permit can issue first. Three thresholds apply and they are commonly conflated: recording is required above $2,500 under Fla. Stat. 713.02(5), filing a copy with the department applies above $5,000, and HVAC repair or replacement contracts under $15,000 are carved out of 713.135(1) entirely. The notice is void if work does not start within 90 days of recording, and it expires one year after recording unless it says otherwise — payments made after it expires are improper payments and can result in paying twice.
Who issues septic permits in Florida, the health department or DEP?
Both, depending on your county. The onsite sewage program transferred from the Department of Health to the Department of Environmental Protection effective 1 July 2021 under the Clean Waterways Act, and the rule chapter was renumbered from 64E-6 to 62-6, F.A.C. But the transfer is phased and unfinished: DEP issues permits directly in 17 counties — Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, Jefferson, Leon, Liberty, Marion, Okaloosa, Santa Rosa, Wakulla, Walton and Washington — while in the other 50, including every major metro, you file with your county health department's Environmental Health program. One thing that does not vary: under Fla. Stat. 381.0065(4) no building or plumbing permit may issue until you hold the septic construction permit, and occupancy cannot be authorized until the final installation is approved.
Do owner-builders have to hire licensed contractors for major trades in Florida?
Only when you hire the work out. If you personally do the work under the owner-builder exemption, you can self-perform trades including electrical and plumbing on a home you will occupy. But anyone you pay to do electrical, plumbing, HVAC, roofing, pool/spa, septic, or well work must be a state-licensed contractor. You cannot pay unlicensed help to run a trade, and any unlicensed worker on your site must be your supervised, payrolled employee.

Last updated: September 2026. Verified this update against the Florida Statutes at flsenate.gov, the Florida Administrative Code at flrules.org, and the Florida Building Commission's own documents at floridabuilding.org. This pass corrected several substantive errors in the prior version: septic is regulated by the Department of Environmental Protection, not the Department of Health, following the 1 July 2021 transfer under the Clean Waterways Act — but the transfer is phased, and 50 of 67 counties still permit through the county health department's Environmental Health program; the 9th Edition (2026) has no adopted effective date and the previously printed December 31, 2026 figure was not supportable; the blower door limit is 7 ACH50, not 5; impact glass is not mandatory in Miami-Dade — approved shutters satisfy FBC Residential R301.2.1.2, which even retains a plywood option; permit validity lives in the FBC administrative chapter (105.3.2, 105.4.1, 105.4.1.3), not in statute; special inspectors do not apply to houses, since threshold buildings under § 553.71(12) are over three stories or 50 feet; Florida does not use REScheck; the septic and well owner-DIY claims were narrowed to what § 381.0065(4), Rule 62-6.004(3) and § 373.326(2) actually say; and the county wind-speed table was replaced with the parcel-specific ASCE 7-22 lookup the code itself now points to. Added this pass: the Notice of Commencement and its three thresholds (§§ 713.02(5), 713.13, 713.135), the statutory rule that a septic construction permit must precede the building permit (§ 381.0065(4)), Florida Product Approval as a purchasing constraint (§ 553.842), the § 553.792 plan review clock and its fee reductions, the § 553.791 private provider option, the coastal construction control line (§ 161.053, Rule 62B-33), and the expiry of local code amendments on the triennial cycle (§ 553.73(4)(e)). All cost, fee, and timeline figures in this guide are illustrative planning ranges, not quoted fees or published schedules. Permit fees, impact fees, code editions, and owner-builder trade policies vary by county and change without notice — always verify current requirements with your local building department, and separately with the office that permits septic and wells for your parcel, before beginning construction.
