Arkansas Owner-Builder Permit Guide

By a retired general contractor with 15+ years building custom homes — about the author. Last updated: September 2026.

Quick Answer: Can You Build Your Own House in Arkansas?

Yes. Arkansas requires a residential builders license when the cost of residential work exceeds $2,000, but a person building their own residence is exempt under Ark. Code Ann. § 17-25-513(1) — the only condition is that you not build more than one residence in any calendar year. There is no holding period, no not-for-sale window, no dollar cap on the exemption, and no state owner-builder affidavit.

The building code is the Arkansas Fire Prevention Code (AFPC), 2021 Edition, whose Volume III is the 2021 International Residential Code with Arkansas amendments, effective January 1, 2023. Here is the part that trips people up: Arkansas has a statewide code and no statewide permit. Cities "may" require a building permit; counties have no enumerated power to run a building-code program at all, and most never created one. Of fourteen counties whose own department lists we read in September 2026, exactly one — Benton — requires a building permit in unincorporated areas.

Arkansas also has homeowner exemptions for electrical, plumbing and HVAC work, but they are three differently worded tests, not one rule, and two of them expressly bow to local ordinance. Read that section before you plan your own trade work.

RequirementOwner-builder in Arkansas
State license to build your own homeNot required. Ark. Code Ann. § 17-25-513(1) exempts a person acting as a residential building contractor in the construction of his or her residence, unless more than one residence is built in a calendar year
Conditions on that exemptionOne residence per calendar year. That is the entire condition — no holding period, no resale ban, no affidavit, no dollar limit
Who requires a building permitLocal option. Cities of the first class 'may' require one (§ 14-56-202); counties act under a general services power in which building codes are not an enumerated service (§ 14-14-802). Most counties issue no residential building permit
Can a homeowner pull their own permitYes, in jurisdictions that issue permits. Proof of ownership is typical; there is no state owner-builder affidavit
DIY electrical, plumbing & HVACThree separate exemptions with three different tests — electrical 'primary residence', plumbing 'owned and occupied', HVACR 'existing building or structure'. See the trade section
Licensed trades (if you hire out)Residential builder over $2,000 (Contractors Licensing Board); electrical (Board of Electrical Examiners, Dept. of Labor & Licensing); plumbing & gas (Dept. of Health); HVAC/R (HVACR Licensing Board, Dept. of Labor & Licensing)
The $50,000 figure you will see quotedThat is the commercial threshold, and § 17-25-101(a)(1) and (c) expressly except single-family residences. It never applies to a house
Current code editionsAFPC 2021 (2021 IRC/IBC/IFC) effective January 1, 2023; electrical is the 2026 National Electrical Code with Arkansas amendments (17 CAR § 210-401)

Arkansas is one of the more contradictory owner-builder states in the country. It writes one building code for the entire state, forbids local governments from adopting a different one — and then requires nobody to enforce it on your house. The code binds your dwelling as a construction standard everywhere. The inspection that would catch a mistake exists only where a city, or one of a handful of counties, decided to create a building department.

That split — one code on the books, an inspector almost nowhere outside city limits — is the single most important thing to understand before you build here. It is genuine freedom for a rural owner-builder and a genuine transfer of responsibility, because the standard still applies to you whether or not anyone shows up to check it.

Arkansas Building Code Overview

The Big Picture: one code, and usually no permit

Arkansas adopts a single statewide building code and tells local governments they may not adopt a different one. What it does not do is require anyone to issue a permit, review a plan, or inspect a house.

The code's own text concedes the choice. AFPC Volume I § 101.2.2 says the AFPC "shall be the only foundation document available for modification by local jurisdictions should they choose to adopt more stringent provisions." Cities "may" require a permit (Ark. Code Ann. § 14-56-202). Counties have no statute that plainly authorizes a building-code program — they act under a general services power at § 14-14-802 in which "building codes" is not among the enumerated services, and the county planning subchapter enumerates "zoning, subdivision, setback, or entry control" ordinances and again omits building codes (§ 14-17-207(a)).

Nothing is delegated. Every verb is "may."

The AFPC is adopted and enforced by the State Fire Marshal, and that office has moved. Act 841 of 2023 relocated the State Fire Marshal into the Office of Fire Protection Services, Division of Emergency Management (Ark. Code Ann. § 20-22-1009), repealed most of the old §§ 12-13-1xx series, and re-enacted the Fire Marshal's duties — including "enforce the Arkansas Fire Prevention Code and periodically revise and update" it — at § 20-22-1010. Almost every guide on the web, including earlier versions of this one, still names the Arkansas State Police, because the 2021 code's own front matter predates the move.

One trap worth naming: § 12-13-120 is still on the books and is still titled "Arkansas Fire Prevention Code." It is a storm-shelter provision for educational occupancies, not the adoption authority. It is exactly the section a search will hand you, and it is the wrong one.

The adopting rule sits in the Code of Arkansas Rules under the Office of Fire Protection Services. The code text itself is readable free at codes.iccsafe.org — Volume III is the residential one.

What Arkansas Deleted from the Residential Code

This is the part that will bite you if you work from a national IRC source. Arkansas struck whole chapters out of Volume III and replaced them with pointers to separate Arkansas codes:

IRC content deleted from AFPC Volume III and where it went instead
IRC contentArkansas treatment
Chapter 11, Energy EfficiencyDeleted in its entirety — refer to the Arkansas Energy Code
Chapter 24, Fuel GasDeleted in its entirety — refer to the Arkansas State Gas Code
Chapters 25–33, all plumbingDeleted in its entirety — refer to the Arkansas State Plumbing Code
Chapters 34–43, all electricalDeleted — refer to the National Electrical Code as adopted by the Arkansas Board of Electrical Examiners
Every appendixDeleted in its entirety
Arkansas adopted no IRC appendices — so there is no state tiny-house code path

AFPC Volume III § R102.5: appendices "are NOT adopted by the State of Arkansas and shall not apply unless adopted by local ordinance," and the volume's table of contents strikes every appendix.

That means Arkansas has adopted no Appendix AQ Tiny Houses, no strawbale, cob, light straw-clay or 3D-printed construction appendix, and no private sewage disposal appendix, at state level. If you are planning alternative construction, there is no state code path to point an official at — a local jurisdiction would have to adopt the appendix by ordinance. (A small internal inconsistency to be aware of: the table of contents strikes appendices AA through AX while § R102.5 names AA through AW. Either way, nothing survives.)

Who Actually Requires a Building Permit

Arkansas publishes no register of which jurisdictions issue building permits, so this has to be established parcel by parcel. The reliable method is to pull your county's own department list: when a county lists Assessor, Collector, Clerk, Judge, Sheriff, Road and Emergency Management — and no Building, Planning or Permits office — that absence is your answer.

Here is what that method returned for fourteen counties in September 2026.

County building permits in unincorporated areas — verified against each county's own published department list, September 2026
CountyCounty building permit outside city limits?What it does require
BentonYes — the only full yes of the fourteenBuilding permits for new construction, additions and interior remodels of single-family homes; floodplain permit; road-department driveway permit
PulaskiPartial — Lake Maumelle Watershed onlyThe county's own form list names a Building Permit Application for that watershed and nowhere else
WashingtonNo — stated in the county's own wordsBut countywide zoning, floodplain development permits, a septic ordinance with no acreage exemption, and a perc test before you get a 911 address
FaulknerNoA floodplain permit is required countywide before any development, through Emergency Management
GarlandNoFloodplain construction permits through Emergency Management, which also issues exemption certificates outside flood hazard areas
Craighead, SalineNoSubdivision review and floodplain permits only
Sebastian, White, Crawford, Baxter, BooneNoNo building, planning or permits office appears on the county's department list at all
Lonoke, CarrollNo permit foundNo enumerable county department list was available — verify by phone before relying on either way

Twelve of fourteen — including three of the four largest counties in the state — require no county building permit in unincorporated areas. But "no building permit" is never "no permits." Every county in the sample still had at least one construction touchpoint: floodplain, 911 addressing, a road-department driveway tie-in, and the septic permit that applies statewide.

Washington County: no building permit, and the most regulated 'no' in the state

Washington County's own Planning page states it plainly: the county "does not enforce building codes for agricultural buildings, single-family homes, or residential accessory structures … in unincorporated areas. As a result, no building permits or inspections are required, and no certificates of occupancy will be issued unless specifically requested."

Do not read that as "no rules." The entire county is zoned — every parcel carries "Agricultural/Single-Family Residential, one (1) unit per acre." Planning issues floodplain development permits. County septic ordinances require a permit on a tract of any size, with no large-lot exemption. And the county gates your 911 address on an approved soil analysis or perc test, which inverts the usual order: in Washington County the soil test comes before the address, not after.

Benton County is the exception — do not let the rural pattern near it

Benton County requires building permits for new construction, additions and interior remodels of single-family homes in unincorporated areas. Group U accessory structures — detached shops, carports, storage buildings, decks, fences — were exempted from the building permit effective November 28, 2023, but trade permits for electrical, plumbing and HVAC are still required for them, and Planning's site-plan review still applies even where no building permit does.

If you are lot-shopping across the Benton/Washington county line, that difference is worth more than a few thousand dollars of fees. Confirm it against the county's own page before you buy.

Arkansas-Specific Amendments and Conditions

The AFPC adapts the base IRC, and local design criteria fill in the site-specific values:

  1. Frost depth: Shallow — Little Rock's published design criteria set the frost line at 12 inches, with a minimum footing 18" wide and 12" deep. Northern Arkansas jurisdictions may require deeper footings; verify locally
  2. Wind: Arkansas sits in the interior severe-storm belt. Little Rock's design criteria use a 115 mph basic (ultimate) design wind speed for ordinary Risk Category II homes
  3. Seismic: The northeast counties near the New Madrid Seismic Zone require elevated seismic design (see the dedicated section below); most of the state is low-seismic. Your seismic site class is determined by investigation at your site, not from a citywide map — do not accept a number someone quotes for "Little Rock" as applying to your lot
  4. Snow: Light — Little Rock design ground snow load is 10 psf; northern counties somewhat higher
  5. Storm shelters and sprinklers: Not mandated for one- and two-family dwellings statewide despite heavy tornado activity
No statewide sprinkler or storm-shelter mandate

Arkansas does not require residential fire sprinklers or storm shelters in one- and two-family dwellings, even though the state is squarely in tornado country. Shelters are strongly encouraged but voluntary — see the hazard section for why you should build one anyway.

Arkansas Owner-Builder Laws

Where the freedom comes from

Arkansas licenses residential homebuilders, then carves out a clear statutory exemption for a person building their own residence. That exemption is the legal foundation for owner-building here, and it is unusually clean — one condition, and nothing else.

Arkansas licenses residential builders through the Arkansas Contractors Licensing Board, part of the Department of Labor and Licensing. Title 17, Chapter 25 actually holds two separate regimes, and confusing them is the fastest way to publish a wrong number:

The statutes are published in full by the Board itself: Residential Contractors Licensing Law and Commercial Contractors Licensing Law, both revised April 2026.

Under Ark. Code Ann. § 17-25-513:

Two supporting definitions do a lot of work here. "Own residence" is defined by rule at 17 CAR § 295-101(6) to mean "the personal residence, the principal place of abode, the domicile, or a residence constructed for the occupancy of the person who owns the property." That final clause is what makes the exemption work for a house you do not live in yet — without it, "principal place of abode" would be circular for new construction.

And the exemption reaches managing the job, not just swinging the hammer. "Residential building contractor" is defined at § 17-25-502(2) to include one who "assumes charge in a supervisory capacity or otherwise manages the construction" of a single-family residence. Acting as your own general contractor and hiring subs is inside the exempt activity.

One more definition worth knowing: § 17-25-502(3) defines "single family residence" as a project of "at least one (1) but no more than four (4) units of new construction." A duplex, triplex or fourplex is still residential in Arkansas, not commercial.

The one-home-per-year line is a real statute, not a norm

In most states the "one home per year" limit is an informal local policy. In Arkansas it is written into the licensing exemption itself: build more than one residence in a calendar year and you lose the owner-builder exemption and need a residential builders license. Build one home for yourself and you are clear.

What the statute does not tell you is how the count is measured — start of construction, completion, or certificate of occupancy. A build that straddles a year boundary is ambiguous on the text. If that is your situation, ask the Residential Contractors Committee in writing before you start the second one.

What the Statute Does Not Say

This matters as much as what it does say, because most of the conditions people expect Arkansas to impose are imported from other states' rules. Reading § 17-25-513 and the whole of 17 CAR part 295:

The things that do still apply: local permits and inspections where a jurisdiction issues them, and standard Arkansas residential property disclosure obligations when you later sell.

Licensed Trades (If You Hire Out)

If you hire contractors instead of doing the work yourself, Arkansas licenses the trades through several different boards — and note that plumbing stayed with the Department of Health when electrical and HVACR moved under Labor and Licensing. That split surprises people who assume one agency runs all the trades.

Arkansas trade licensing bodies (apply when you hire these trades out)
TradeLicensing bodyLicense trigger
Residential building (whole-home GC)Arkansas Contractors Licensing Board, Residential Contractors Committee (Dept. of Labor & Licensing)Residential work over $2,000 (§ 17-25-513(3))
Commercial / general contractorArkansas Contractors Licensing Board, commercial side$50,000 or more — but single-family residences are expressly excepted (§ 17-25-101(a)(1), (c)), so this does not reach a house
ElectricalArkansas Board of Electrical Examiners (Dept. of Labor & Licensing), Title 17 Ch. 28Electrical work, unless exempt (§ 17-28-304)
Plumbing & natural gasCommittee of Plumbing Examiners, Arkansas Department of Health, Title 17 Ch. 38Plumbing / gas installation (§ 17-38-301)
HVAC/RHVACR Licensing Board (Dept. of Labor & Licensing), Title 17 Ch. 33, Class A through E plus LHVACR contracting (§ 17-33-303)
Residential roofingResidential Contractors Committee — registration under § 17-25-601 et seq.Roofing contracting; owner exemption mirrors the builder one at § 17-25-610
Hiring an unlicensed contractor is a penalty on YOU, not just on them

This is the least-known provision in the Arkansas licensing law and it points straight at the owner. Ark. Code Ann. § 17-25-510(b) authorizes a civil penalty of "not less than one hundred dollars ($100) nor more than four hundred dollars ($400) for each day that the violation occurred" — and subdivision (b)(2) applies that penalty to "using a contractor in violation of this chapter."

Hiring an unlicensed sub is not only the sub's problem. Verify every license at the Board's contractor lookup before the first invoice, and keep the printout in your job file.

The flip side protects you: under § 17-25-515 a residential contractor who works in violation of the subchapter "shall not bring an action" to enforce the contract or for quantum meruit. Unlike the commercial chapter, there is no cure provision. An unlicensed residential contractor in Arkansas cannot sue you for the money.

Homeowner Doing Their Own Trade Work

Every guide you will read says Arkansas lets you do your own electrical, plumbing and HVAC. All three exemptions do exist. But read the verbs — they are three different tests, and the differences decide whether they reach a house that is not finished and not occupied.

The three homeowner trade exemptions — the wording, and what it does
TradeThe exemption, in its own wordsWhat that wording does to a house under construction
Electrical — § 17-28-102(b)Nothing in the chapter requires a license “before doing electrical work on his or her primary residence except as otherwise required by state law, rules, regulations, or local ordinances.” “Primary residence” is defined as “an unattached single-family dwelling used as the person’s primary place of residence” (§ 17-28-101(9))Present tense — “used as.” Its application to a not-yet-occupied new build is not addressed in the statute. Expressly subject to local ordinance
Plumbing — § 17-38-302(1)The licensing provisions do not apply to “plumbing work done by a property owner in a building owned and occupied by him or her as his or her home except when the license is required by local ordinance”Owned AND occupied. No rule extends this to a residence merely constructed for future occupancy. Also expressly subject to local ordinance
HVAC/R — § 17-33-102(b)(1)The chapter does not apply to a person who “performs HVACR work in an existing building or structure owned and occupied by him or her as his or her home”On the face of the text, an “existing building” is not a house you are building. This is the narrowest of the three
The honest answer on new construction: nobody has resolved it

Whether these three exemptions reach an unoccupied new build is the highest-value unresolved question in Arkansas owner-builder law. There is no Arkansas appellate case on it, no board rule, and no published opinion letter settling it. Anyone who tells you flatly that you may wire and plumb your own new house in Arkansas is reading past the words.

The HVACR one is the starkest — "existing building or structure" plainly describes something that already exists. On the text alone, an owner-builder installing a system in a house they are building is not inside it.

What to do about it: write to each board — the Board of Electrical Examiners, the HVACR Licensing Board (both at the Department of Labor and Licensing) and the Plumbing and Natural Gas Section at the Department of Health — describe your actual situation, and keep the written answers in the job file. That is the only way to be certain, and a written answer is worth having if anyone questions the work later.

Two further constraints on the electrical side that most guides miss:

And one on the plumbing side worth raising with the Department of Health if you build inside a city or a water, sewer or gas utility district: § 17-38-301(b)(1) separately requires that in any such area, "no person, firm, or corporation shall install plumbing unless a licensed master or restricted licensed plumber who shall be responsible for proper installation is in charge at all times." That is a jobsite supervision mandate, textually distinct from the licensing exemption, and how the two fit together for an owner-builder is not settled in the statute.

Liability and Insurance

As owner-builder, the liability is yours

As an owner-builder in Arkansas:

  • You're personally liable for injuries on your job site (carry workers' comp for any paid labor)
  • Builder's risk insurance is available but priced higher than for licensed builders
  • Some construction lenders require owner-builders to carry liability coverage during the build
  • Arkansas residential property disclosure obligations apply for years after you sell
  • The electrical homeowner exemption carries an express sting in its own text: it "shall not be referred to in any way and shall not be any evidence of the lack of negligence or the exercise of due care" in a civil damages trial (§ 17-28-102(b))

Permit Costs in Arkansas

These are illustrative planning estimates — verify before budgeting

The figures below are illustrative planning ranges compiled from published fee schedules, several of which date from 2023 and were not re-verified for this update. Arkansas cities set fees by ordinance and they change often. Confirm exact amounts with the department that will issue your permit before budgeting. Outside city limits in a county with no building department, your building-permit cost is $0 — but the septic permit still applies, and so may a floodplain permit.

Arkansas permit costs are low to moderate. Most cities charge a valuation-based building permit fee (calculated from the ICC Building Valuation Data table) plus separate trade and plan-review fees. The Northwest Arkansas cities add impact fees that can dwarf the permit itself.

Major Cities

Estimates below are for a 2,000 sq ft home, roughly $300,000–$350,000 of valuation, which is what most Arkansas cities use to compute fees.

Little Rock (Pulaski County) illustrative permit cost estimate for a 2,000 sq ft home
Cost itemIllustrative amount
Building permit (valuation-based)Roughly $1,000 at $300K valuation on the schedule we found; confirm the current ordinance

Electrical permit (1–2 family new)Around $0.10 per sq ft under roof
Residential certificate of occupancyAbout $30
Sewer/water connection fees$2,500–$6,000
Total typical cost$4,500–$8,500

Plan reviewConfirm current rate
Trades & utilities$2,500–$6,000
Total typical cost$8,000–$12,000
Bentonville's impact fee sets it apart

Bentonville charges roughly $3,800 in impact fees on a single-family home — among the highest in Northwest Arkansas and far larger than the building permit itself. Most of that is the parks fee. Neighboring cities and unincorporated areas charge much less or nothing.

If NW Arkansas impact fees matter to your budget, compare Bentonville, Rogers, Springdale, and unincorporated Benton and Washington counties before you buy the lot — and remember that unincorporated Benton County still requires a building permit while unincorporated Washington County does not.

Fort Smith, Springdale, Rogers, and Conway illustrative permit cost estimates for a 2,000 sq ft home

Rogers (Benton County)~$1,000–$1,200 + impact fees$5,500–$9,500
Conway (Faulkner County)~$900–$1,100$4,500–$8,000

Hidden Fees

Hidden fees Arkansas owner-builders should budget for (illustrative unless a rule is cited)
FeeTypical amount / note
NW Arkansas impact feesOften the largest add-on in Bentonville and Rogers (parks, police, fire, library)
Sewer/water tap & connection fees$2,500–$6,000 in cities; private well and septic instead in rural areas
Driveway / culvert permit (county road tie-in)$100–$400 — this one exists even in counties with no building department
Floodplain development permitRequired countywide in several counties regardless of building permits; some issue an exemption certificate instead if you are outside the flood hazard area
Septic plan review (ADH)$30 to $150 by conditioned square footage — a published fee schedule at Onsite Wastewater Rules § 4.9.1, not an estimate
Septic design (Designated Representative)A private professional you hire; priced by the DR, not by the state
Well drillingNo permit exists — drilling is priced per foot
Stormwater / land disturbance$0–$800 depending on lot size and city; the state construction general permit triggers at one acre disturbed
Re-inspection fees$45–$50 per trip in most cities

Processing Timelines

Faster than the coasts; nonexistent in no-permit counties

Arkansas city permitting is generally quick. In an unincorporated county with no building department there is no plan review at all — but you still cannot break ground before the septic approval, which state rule requires "prior to construction of a building or residence."

Illustrative permit processing timelines by jurisdiction
JurisdictionTime to permit
Little Rock3–6 weeks
Fayetteville3–6 weeks
Bentonville / Rogers3–6 weeks (plus impact-fee processing)
Fort Smith, Springdale, Conway2–5 weeks
Smaller incorporated towns1–3 weeks
Counties with no building departmentNo building permit — but budget for the septic permit sequence

Energy Code Requirements

We are not printing an Arkansas insulation table, and here is why

AFPC Volume III deletes IRC Chapter 11 in its entirety and points to the separate Arkansas Energy Code for New Building Construction. That much is verified from the code's own table of contents.

What we could not verify in September 2026 is the current edition or the instrument that adopts it. The widely repeated answer is a weakened 2009 IECC base with 2014 amendments, but the pages that carried it sit on retired agency paths and no current adopting document or agency landing page could be reached. The Energy Office sits within the Department of Energy and Environment — not, as a great many guides still say, the Arkansas Economic Development Commission.

We would rather tell you the honest state of the record than print an R-value table you might build to. Ask your jurisdiction, or the Energy Office, which edition applies, and get the answer in writing before you order insulation and windows.

Climate Zones

Arkansas spans two IECC climate zones, and that much is stable regardless of which edition governs:

Arkansas IECC climate zones by county
ZoneCountiesCharacter
3A (warm-humid)Most of the state — Little Rock, Fort Smith, the Delta, southern and central ArkansasCooling-dominated
4A (mixed-humid)Northern tier — Benton, Washington, Carroll, Boone, Baxter, Marion, Fulton, Izard, Madison, Newton, Searcy, StoneMixed heating/cooling
Build above whatever the code turns out to be

Arkansas's energy minimums have historically been among the lightest in the country, which means the prescriptive floor leaves real money on the table in a state with hot, humid summers and meaningful winter heating in the north. Attic insulation, air-sealing and better windows pay back quickly here — fastest in 4A Northwest Arkansas. You will not regret exceeding the code on the envelope, whichever edition applies.

Foundation and Frost Depth

Representative minimum frost depths by region (verify with your jurisdiction)
RegionMinimum frost depth
Central / southern Arkansas (Little Rock and south)12 inches
Northern Arkansas (Ozarks, NW counties)12 inches or more — some jurisdictions require deeper
Shallow frost depth, but expansive soils matter more

Arkansas frost depths are shallow (Little Rock specifies 12 inches), so frost heave is rarely the foundation problem. Expansive clay is — see the special considerations section. Get the foundation right for the soil, not just the frost line.

Inspection Requirements

Where a jurisdiction issues permits, the inspection list comes straight from AFPC Volume III § R109, which Arkansas left unamended: foundation after the trenches or basement are excavated; plumbing, mechanical, gas and electrical rough "prior to covering or concealment"; a floodplain inspection on placement of the lowest floor where applicable; frame and masonry after the roof and framing are in place; any other inspection the building official requires; and final, "after the permitted work is complete and prior to occupancy."

Standard Arkansas city inspection schedule
#InspectionWhen
1FootingAfter excavation, before pour
2Foundation / slab (plumbing under-slab)Before slab pour
3Underground / rough electricalBefore cover
4Plumbing rough-inSlab and rough stages
5Mechanical / duct rough-inBefore cover
6FramingAfter dry-in, before insulation
7InsulationBefore drywall
8Gas line / pressure testDept. of Health or its delegated inspector where applicable
9Final electricalBefore CO
10Final plumbingBefore CO
11Final mechanicalBefore CO
12Final building / Certificate of OccupancyAfter all work complete, prior to occupancy (§ R110)
The asymmetry nobody tells you: plumbing inspection is mandatory, electrical is optional

These two read as a matched pair and they are not. The difference is one verb.

Plumbing — "shall." The Arkansas plumbing code is adopted as "minimum standards statewide in application … to all types of buildings, private or public, rural or urban" (§ 17-38-103). And § 17-38-204(c) requires that a city, town, sewerage district, water district, water association, utility gas system or county having a water, sewer or gas utility system "shall establish a system of permits and inspections." Work may not be started "without the prescribed licenses, permits, and acceptable plan review" where required (§ 17-38-204(b)(2)). Where a utility system exists but no local inspector was provided, the Department of Health "may take immediate charge and entire control of the plumbing inspection program" (§ 17-38-204(f)(1)).

Electrical — "may." § 17-28-305(c): "Any city or county may establish by ordinance, rules, and regulations a system of permits and inspections for the installation, repair, and maintenance of electrical facilities and electrical work."

So in a rural Arkansas build your electrical work may genuinely never be inspected — while the plumbing, if you are inside any kind of utility district, is supposed to be.

But the state kept a reach-in on electrical. Under 17 CAR § 210-1101(a) a state electrical inspector "may require electrical work to be exposed for inspection, including the removal of sheetrock" where the work was never subject to city inspection and there is evidence of serious violations. Exempt from routine inspection is not the same as beyond reach.

Arkansas is on the 2026 NEC — with its own amendments

This is the opposite of the usual trap. Most states lag on the electrical code; Arkansas is current. 17 CAR § 210-401 adopts the National Electrical Code, 2026 edition, as "the standard for the construction, installation, repair, and maintenance of electrical facilities and the performance of electrical work" — published in the Board of Electrical Examiners' own administrative rules.

It does not adopt it clean, and the amendments land in your kitchen and laundry:

  • AFCI and GFCI protection is not required on dwelling-unit circuits over 130 volts, except for Articles 680 and 682 (§ 210-401(b)(2))
  • AFCI/GFCI does not apply within a dwelling unit to laundry areas — except convenience outlets within six feet of a sink — or to a refrigerator or microwave appliance (§ 210-401(b)(3))
  • Arkansas writes its own island and peninsula receptacle spacing: at least one within the island or peninsula for the first 9 sq ft of countertop, one more per additional 18 sq ft, and at least one within two feet of the outer end of a peninsula (§ 210-401(b)(4))
  • The rule also adopts ANSI/NECA 1-2023 as the workmanship standard, and § 210-401(f) says the adoption "does not include any later amendments or editions" — a newer NEC does not take effect here until the Board adopts it

Confirm the edition with the Board before you buy the code book, since the rule text itself carries no effective date.

New Madrid Seismic and Tornado / High-Wind Hazards

This is the section that makes Arkansas different from almost every other Southern state. Two natural hazards drive real design decisions here: violent spring tornadoes statewide, and a serious earthquake threat in the northeast from the New Madrid Seismic Zone.

New Madrid Seismic Zone (Northeast Arkansas)

Northeast Arkansas is genuine earthquake country

The New Madrid Seismic Zone runs through northeast Arkansas — roughly northeast from Marked Tree (Poinsett County) up through Blytheville (Mississippi County). This is the most seismically hazardous region in the central United States. Under Arkansas's seismic-zone statute, Ark. Code Ann. § 12-80-103, counties including Craighead and Mississippi sit in the zone of greatest anticipated damage.

If you build in the northeast — Mississippi, Craighead, Poinsett, Greene, Clay, Crittenden, and neighboring counties — seismic design is not optional theater:

In the northeast, pay for the engineer

Even where an unincorporated county will not inspect your home, the New Madrid hazard is real and physics does not care about permits. Budget for a geotechnical evaluation and an engineered foundation and lateral design if you build anywhere near the NE Arkansas seismic zone. It is the single highest-value professional dollar you will spend there.

Tornadoes and High Wind (Statewide)

Build the safe room — the state won't make you, but you'll want it

Arkansas is hit by violent tornadoes most springs. The code does not require a storm shelter in a one- or two-family home, and Arkansas's homeowner shelter rebate program ended in 2016. There is no state cash to help you build one anymore — but it is still the best safety money you can spend.

Wind and shelter considerations:

Special Arkansas Considerations

Expansive Clay Soils (The Real Foundation Risk)

Expansive clay is the number one foundation hazard in Arkansas

Arkansas's biggest foundation problem is not frost — it is expansive clay. In the Delta, Sharkey clay ("buckshot") swells when wet and shrinks when dry, putting enormous stress on slabs and footings. Get a geotechnical evaluation before you pour.

Where it matters most and what to do:

Septic Systems (Rural Areas)

This is the permit that applies to you whether or not your county has a building department, and it is the one that most often determines whether a rural parcel is buildable at all. The Arkansas Department of Health regulates onsite wastewater under Ark. Code Ann. § 14-236-101 et seq. and the Rules Pertaining to Onsite Wastewater Systems, effective September 5, 2024.

The sequence, and where the surprises are:

  1. The approval comes before the house. Rule § 4.3 requires the application and plans to be submitted to and approved by the Department or its Authorized Agent "prior to construction of a building or residence." Not before occupancy — before construction
  2. You cannot design it yourself. Rule § 4.10.1: Part I of the permit application "shall be completed by a Designated Representative" — a private licensed professional (engineer, surveyor, master plumber, registered sanitarian or similar) certified by the Department to make percolation tests, designs and inspections. Your county health unit will give you the list of DRs working in your area
  3. You may install it yourself. Ark. Code Ann. § 14-236-102(b)(2) requires registration of installers "with the individual homeowner retaining all rights to install and repair his system," and "installer" is defined as someone who does the work for compensation for others (§ 14-236-103(6)). So a homeowner may lawfully install their own system — but the permit is still required, the DR must still design it, and field practice varies by county Environmental Health Specialist. Confirm with your county health unit before you rent the equipment
  4. Soil first, perc test second. Arkansas is a soil-morphology state: a minimum of two soil pits is required, one in the primary absorption area and one in the secondary (§ 7.1), left open for the Authorized Agent. A percolation test is an option after that, not the starting point (§ 8.5)
  5. You need two absorption areas, not one. Every design requires both a primary and a secondary (reserve) absorption area. Buyers shopping raw land routinely underestimate this — plan on roughly twice the suitable soil area you were expecting
  6. The system may not be used until the Permit for Operation issues (§ 4.10.3), which comes after the installation inspection
ADH septic plan-review fee schedule by conditioned square footage (Onsite Wastewater Rules § 4.9.1 — a published fee, not an estimate)
Conditioned structure sizePlan review fee
1,500 sq ft or less$30
Over 1,500 up to 2,000 sq ft$45
Over 2,000 up to 3,000 sq ft$90
Over 3,000 up to 4,000 sq ft$120
Over 4,000 sq ft$150
Alteration, repair or extension$30

Garages, carports and porches are excluded from the square footage (§ 4.9.2.1). The Permit for Construction is valid one year and must be revalidated if older.

The separation distances that decide your site plan

Rule § 6.2 holds the entire statewide separation table for onsite wastewater — and Arkansas deliberately gives the septic tank and the absorption field the same numbers, so one set covers tank, field and lines:

  • 100 feet from any source of domestic water supply — this is the well number
  • 100 feet from the high-water mark of any stream or lake, and 100 feet from any sinkhole
  • 10 feet from any dwelling or building, 10 feet from all property lines, 10 feet from any water service line
  • 50 feet from a pond on the same property; 100 feet from a pond on adjacent property if in the pond watershed
  • 300 feet from a spring used as a public water supply, or from the high-water mark of a body of water within a quarter mile of a public water supply intake

Two things to hold onto. First, these are floors, not entitlements: § 6.1 says minimum distances apply "only where ideal conditions indicate them to be sufficient and greater distances shall be required where local conditions demand." Second, the well side of the table has a multiplier almost nobody publishes — 17 CAR § 11-502(c)(2) requires the lateral distances to be increased, "double the distance for highly pervious gravel formations." In Ozark karst that quietly turns 100 feet into 200.

Sketch the layout before the evaluator walks the lot — the Site Plan Studio is a free tool that places the well, tank and absorption field to scale, measures the separation between each, and prints the sheet at letter size for your permit packet.

The 10-acre septic exemption — real, current, and missing from the rule book

Ark. Code Ann. § 14-236-104(c): "The requirements of this chapter shall not apply to any individual sewage disposal system or alternate and experimental system which is situated on a tract of land ten (10) acres or larger, in which the field line or sewage disposal line is no closer than two hundred feet (200′) to the property line."

The Department's own onsite wastewater guidance confirms and sharpens it: it applies to a single residence on ten or more acres where all parts of the system are more than 200 feet from any property line, "including roads" — and the owner is still required to install and operate the system so it meets state requirements and does not create a nuisance.

Why almost nobody finds it: the exemption is absent from the 81-page 2024 rule. A full-text search of the rule for "ten (10) acres," "10 acres" and "two hundred feet" turns up nothing relevant; the rule's variances-and-exemptions section mirrors § 14-236-104(a) and (b) and omits (c). Cite the statute, not the rule, and expect county health staff to be unfamiliar with it.

Run the geometry before you count on it. On a square 10-acre parcel (about 660 feet a side), a 200-foot buffer on every side leaves roughly a 260-by-260-foot envelope — tight but workable. On a long narrow 10-acre parcel it can be geometrically impossible.

And think hard before using it. § 14-236-104(b) still lets the Department act on a system that becomes a health hazard or nuisance, a municipality may impose stricter local rules (§ 14-236-105), and an unpermitted system can create real problems at appraisal, resale and mortgage underwriting. On most parcels the $30 to $150 plan-review fee is cheap insurance against a financing problem five years out.

Arkansas septic system costs (illustrative planning ranges; the ADH plan-review fee above is the exact figure)
ItemIllustrative cost
Soil evaluation and DR design$300–$700
Standard absorption-field system$6,000–$13,000
Engineered / aerobic system (poor or clay soils)$13,000–$24,000
Drip or advanced treatment on tight soils$15,000–$28,000

Wells

Private wells are common in rural Arkansas, and the regulator is not who most guides say it is. Water well construction is governed by the Arkansas Water Well Construction Act, Ark. Code Ann. § 17-50-101 et seq., and the Arkansas Water Well Construction Rules at 17 CAR Part 11. The Department of Health does not regulate well construction.

The agency changed in 2023. Act 691 of 2023 abolished the Commission on Water Well Construction and transferred its authority, duties, records, personnel and appropriations to the Arkansas Natural Resources Commission, on the Natural Resources side of the Department of Agriculture. Existing licenses and rules were preserved. Do not go looking for the old commission — it does not exist.

Three facts that matter to an owner-builder:

Well siting rules worth knowing before you pick the spot: 100 feet from a septic tank, absorption field, cess pool, leaching pit, pit privy or manure pile; 50 feet from watertight sewers; doubled in highly pervious gravel formations (§ 11-502(c)); at least 10 feet clear of any building projection and 10 feet from any power line, and the casing top may not terminate in a basement or an undrained below-grade pit (§ 11-502(h)). Closed-loop geothermal wells keep 50 feet from a septic tank, its field lines, or other potable wells (§ 11-502(e)).

Arkansas well costs (illustrative planning ranges)
ItemIllustrative cost
Drilling$20–$35 per foot
Typical residential well (150–400 ft)$4,000–$12,000
Pump and pressure tank$1,500–$3,000
Well permitNone exists — there is nothing to pay for

Flooding (Delta and River Corridors)

Eastern Arkansas and the major river bottoms (Mississippi, Arkansas, White, Red) carry real floodplain risk. Check FEMA flood maps before buying; building in a Special Flood Hazard Area triggers elevation requirements and flood insurance.

This is also the permit most likely to exist in a county that has no building department at all. Faulkner County requires a floodplain permit countywide before any development; Garland County issues floodplain construction permits through Emergency Management, and an exemption certificate if you are outside the hazard area; Benton and Washington counties both administer floodplain permits through their planning offices. Ask about it early — it is easy to assume "no building department" means "no county paperwork," and that is wrong nearly everywhere.

Top Counties for Owner-Builders

1. Washington County (Fayetteville, Springdale — NW Arkansas)

2. Benton County (Bentonville, Rogers — NW Arkansas)

3. Faulkner County (Conway — central Arkansas)

4. Saline County (Benton, Bryant — Little Rock suburbs)

Common Questions

Do I need a license to build my own house in Arkansas? No. Arkansas requires a residential builders license when residential work exceeds $2,000, but a person building their own residence is exempt under Ark. Code Ann. § 17-25-513(1) — as long as you do not build more than one residence in a calendar year. That is the only condition: no holding period, no resale restriction, no affidavit. You still pull local building permits in jurisdictions that require them.

Can you build your own house without a permit in Arkansas? In much of the state, yes — because there is no permit to pull. Arkansas has a statewide building code but no statewide building permit and no state residential inspection program. Cities "may" require one and most do; counties have no enumerated power to run a building-code program, and of fourteen counties we checked against their own department lists in September 2026, only Benton required a building permit in unincorporated areas. Confirm your own county before you assume it either way.

What is the Arkansas owner-builder exemption? It is a real statute. § 17-25-513(1) exempts a person acting as a residential building contractor in the construction of his or her residence, unless more than one residence is built in a calendar year. "Own residence" is defined by rule at 17 CAR § 295-101(6) to include "a residence constructed for the occupancy of the person who owns the property," which is what makes it work for a house you do not live in yet. There is no not-for-sale window and no affidavit.

Can a homeowner do their own electrical, plumbing, and HVAC work in Arkansas? All three exemptions exist, but they are three different tests. Electrical covers "his or her primary residence," defined as a dwelling "used as" your primary place of residence. Plumbing covers a building "owned and occupied by him or her as his or her home." HVACR reaches work "in an existing building or structure" — which on its face is not a house under construction. Electrical and plumbing are both expressly subject to local ordinance, and a city may require you to demonstrate technical competency before doing your own electrical work. Ask each board in writing about your specific situation.

Can I install my own septic system in Arkansas? Yes, you may install it — § 14-236-102(b)(2) preserves "the individual homeowner retaining all rights to install and repair his system." But you may not design it: Part I of the application "shall be completed by a Designated Representative" (Onsite Wastewater Rules § 4.10.1). The permit is required either way, the approval must come before construction of the residence, and the system may not be used until the Permit for Operation issues.

Do I need a permit to drill a well in Arkansas? No — there is no well permit and no notice of intent for a private domestic well, and § 17-50-108(b) expressly lets a landowner construct a well for their own use on their own land without a license. What you do owe is compliance with every construction standard in 17 CAR Part 11, and a report of construction within 90 days carrying the well's longitude and latitude.

How much does an Arkansas owner-builder permit cost? In cities, building permits for a typical 2,000 sq ft home run roughly $900–$1,550 on a valuation basis, plus plan review and trade permits. Northwest Arkansas adds impact fees — Bentonville's run around $3,800 per home on the schedule we found, which dates from 2023. In a county with no building department the building-permit cost is $0, but the septic plan review ($30 to $150) and often a floodplain permit still apply.

Which Arkansas counties are best for owner-builders? Washington County pairs NW Arkansas growth with no building permit in unincorporated areas, at the cost of countywide zoning and a septic ordinance with no acreage exemption. Benton County has the strongest economy but is the one county in our sample that requires a building permit outside city limits. Faulkner and Saline suit central-Arkansas builders. The Ozark counties offer the lowest cost and least red tape, with harder financing and karst geology as the trade-off.

Does Arkansas require a storm shelter? No. Despite heavy tornado activity, the code does not require a storm shelter in one- and two-family homes, and the state homeowner rebate program ended in 2016. Most experienced Arkansas owner-builders build one anyway.

Typical Owner-Builder Timeline

Phased Arkansas owner-builder timeline (illustrative)
PhaseTasks
Months 1–2: Pre-permitEstablish whether your jurisdiction issues a building permit at all; hire the Designated Representative and get the soil pits dug; site/soils evaluation (critical on clay); plans; engineer for foundation (NE seismic or expansive clay)
Months 2–3: ApprovalsSeptic permit — required before construction of the residence, everywhere. City: submittal, review, impact fees, permit issuance. Floodplain permit where the county requires one. 911 address and driveway/culvert permit
Months 3–5: Foundation and shellExcavation and footings; engineered slab or foundation pour; framing, sheathing, roof; dry-in; framing inspection where one exists
Months 5–7: Rough-insElectrical, plumbing, mechanical, gas rough-ins; insulation; drywall. Plumbing inspection is mandatory inside a utility district even where nothing else is
Months 7–10: FinishesCabinets, flooring, trim, paint; final inspections; Permit for Operation on the septic system; Certificate of Occupancy where issued

Total: 8–11 months (part-time owner-builder). Full-time, 6–9 months.

Final Thoughts for Arkansas Owner-Builders

Arkansas rewards owner-builders who match their build to the state's split personality. Inside the cities — Little Rock, Fayetteville, Bentonville — you get a real code, real inspections, and reasonable fees (impact fees aside). Out in the unincorporated counties, you will often face no building permit at all, which is genuine freedom and genuine responsibility in equal measure.

The big decisions:

  1. Establish your enforcement level deliberately, in writing. Pull your county's own department list and see whether a building office exists. A no-permit county means freedom but also no safety net and tougher financing and resale. A city means oversight but cleaner title and easier loans. Choose on purpose
  2. Use the owner-builder exemption correctly: one home per calendar year, built for your own occupancy. Stay inside § 17-25-513(1) and you need no builders license — and do not import conditions from other states that Arkansas never wrote
  3. Verify every contractor's license before the first invoice. § 17-25-510(b)(2) puts a $100-to-$400-per-day civil penalty on the owner who uses a contractor in violation of the chapter. That one is on you, not on them
  4. Get the trade exemptions in writing before you plan on them. Three different tests, and the HVACR one says "existing building." Ask each board about your actual situation rather than trusting a summary — including this one
  5. Treat the septic permit as the real gate. It applies whether or not your county has a building department, the approval must come before you build, and you cannot design the system yourself. If your parcel is ten acres or more, read § 14-236-104(c) carefully before deciding whether to use it
  6. Engineer for the soil and the seismic zone. Expansive clay statewide and New Madrid seismic in the northeast are the two things that wreck Arkansas houses. Spend on geotech and structural engineering even where no one makes you
  7. Build the storm shelter. The state will not require it or pay for it anymore. Build it anyway

Arkansas is a strong state for the practical, self-reliant owner-builder. Pick the right county, respect the soil and the seismic zone, get the trade questions answered in writing, and the freedom here is real.

Arkansas Owner-Builder FAQs

Can you build your own house in Arkansas without a license?

Yes. Arkansas requires a residential builders license when the cost of residential work exceeds $2,000, but Ark. Code Ann. 17-25-513(1) exempts a person who acts as a residential building contractor in the construction of his or her residence, unless he or she builds more than one residence during any calendar year. That one-per-calendar-year cap is the entire condition. There is no holding period, no not-for-sale window, no dollar limit on the exemption, and no state owner-builder affidavit to file. You still pull building permits in jurisdictions that issue them, and the home must still meet the Arkansas Fire Prevention Code.

Do you need a contractor's license to build your own home in Arkansas?

No, not for your own residence. The exemption is at 17-25-513(1), and the rule at 17 CAR 295-101(6) defines 'own residence' to include 'a residence constructed for the occupancy of the person who owns the property' — which is what makes it work for a house you do not live in yet. It also covers acting as your own general contractor, because 'residential building contractor' is defined at 17-25-502(2) to include one who assumes charge in a supervisory capacity or otherwise manages the construction. The $50,000 figure you will see quoted is the commercial threshold, and 17-25-101(a)(1) and (c) expressly except single-family residences — it never applies to a house.

Can a homeowner do their own electrical and plumbing in Arkansas?

All three trade exemptions exist, but they are worded differently and the differences matter for a house that is not finished. Electrical exempts work on 'his or her primary residence,' defined as an unattached single-family dwelling 'used as' the person's primary place of residence (17-28-102(b), 17-28-101(9)) — present tense. Plumbing covers a building 'owned and occupied by him or her as his or her home' (17-38-302(1)). HVACR is narrowest: it reaches work 'in an existing building or structure' (17-33-102(b)(1)), which on its face is not new construction. Electrical and plumbing are also expressly subject to local ordinance, and 17-28-305(b)(2) lets a city or county require you to demonstrate technical competency before doing your own electrical work. No Arkansas case or board rule settles whether these reach an unoccupied new build — ask each board in writing.

What is the Arkansas owner-builder exemption?

It is a statutory exemption at Ark. Code Ann. 17-25-513. Subdivision (1) exempts a person acting as a residential building contractor in the construction of their own residence, unless they build more than one residence during any calendar year. Subdivision (2) exempts an owner acting as their own home-improvement contractor on their own property, with no annual cap in its text, and subdivision (3) exempts any project costing $2,000 or less, with an anti-splitting rule. Contrary to what most guides say, the exemption contains no resale restriction and no occupancy period — the rule's test is purpose at the time of building.

Can you build your own house without a permit in Arkansas?

It depends entirely on where you build, and in much of Arkansas there is no permit to pull. Arkansas adopts one building code statewide and forbids local governments from adopting a different one, but nothing requires a city or county to issue a permit or inspect a house. Cities 'may' require a permit (14-56-202) and most do. Counties act under a general services power in which building codes are not an enumerated service (14-14-802), and of fourteen counties checked against their own published department lists in September 2026, only Benton County required a building permit in unincorporated areas — Pulaski requires one only in the Lake Maumelle Watershed. Washington County states on its own Planning page that no building permits or inspections are required and no certificates of occupancy will be issued unless requested. Confirm your own county before assuming either way.

How much does an Arkansas owner-builder permit cost?

In cities, the building permit for a typical 2,000 sq ft home runs roughly $900 to $1,550 on a valuation basis, plus plan review and separate trade permits. Northwest Arkansas adds impact fees — Bentonville's ran about $3,800 per single-family home on the 2023 schedule we found, which was not re-verified for this update. In a county with no building department the building-permit cost is $0, but two costs survive: the septic plan review, which is a published ADH fee of $30 to $150 by conditioned square footage, and often a floodplain development permit. All city figures here are illustrative planning ranges — confirm with the department that will issue your permit.

What building code and NEC edition does Arkansas use in 2026?

The Arkansas Fire Prevention Code, 2021 Edition, effective January 1, 2023 as a state rule. Volume III is the residential one — the 2021 International Residential Code with Arkansas amendments — and it applies to detached one- and two-family dwellings and townhouses not more than three stories above grade. Electrical is the 2026 National Electrical Code, adopted at 17 CAR 210-401 with Arkansas amendments to the AFCI and GFCI requirements and to island and peninsula receptacle spacing. What surprises people is how much Arkansas struck out of Volume III: IRC Chapter 11 energy, Chapter 24 fuel gas, Chapters 25-33 plumbing and Chapters 34-43 electrical are all deleted and replaced by pointers to separate Arkansas codes — and every appendix is deleted, so Arkansas has adopted no tiny-house, strawbale, cob or 3D-printed-construction appendix at state level.

If nobody inspects my house in Arkansas, does the building code still apply?

Yes. The Arkansas Fire Prevention Code is adopted statewide and Volume III reaches your dwelling by its own scope. What is missing in a county with no building department is the inspection, not the standard, and not your liability for falling short of it. Three things bite regardless of your county: the onsite wastewater permit; the plumbing code, adopted as minimum standards statewide in application, rural or urban (17-38-103), with permits and inspections mandatory wherever a water, sewer or gas utility system exists (17-38-204(c)); and the 2026 NEC as the standard for electrical work. Even the electrical exemption from routine inspection has a sting — under 17 CAR 210-1101(a) a state inspector may require electrical work to be exposed for inspection, including the removal of sheetrock, where the work was never subject to city inspection and there is evidence of serious violations.

Do I need to design for earthquakes in Arkansas?

In northeast Arkansas, yes. The New Madrid Seismic Zone runs through counties including Mississippi, Craighead, and Poinsett, and Ark. Code Ann. 12-80-103 places that region in the zone of greatest anticipated earthquake damage. Deep, soft soils there amplify ground motion, so seismic design of your foundation, bracing, and connections matters — a structural engineer is strongly recommended even in unincorporated counties that do not inspect. Your seismic site class is established by investigation at your site rather than read off a citywide map. Most of the rest of Arkansas is low-seismic.

Last updated: September 2026. Verified against the Arkansas Code at arkleg.state.ar.us, agency rules in the Code of Arkansas Rules, the Arkansas Fire Prevention Code's own adopted text at codes.iccsafe.org, the Contractors Licensing Board and Board of Electrical Examiners statute books published by the Department of Labor and Licensing, and the Department of Health's Rules Pertaining to Onsite Wastewater Systems effective September 5, 2024, in September 2026.

Key points corrected in this update: the State Fire Marshal was relocated to the Office of Fire Protection Services, Division of Emergency Management by Act 841 of 2023 (§ 20-22-1009), not the Department of Public Safety's police division, and the old §§ 12-13-1xx adoption sections were repealed. Arkansas is on the 2026 National Electrical Code (17 CAR § 210-401) with Arkansas amendments to AFCI/GFCI and island receptacles. The owner-builder exemption at § 17-25-513(1) carries a one-residence-per-calendar-year cap and nothing else — no holding period, no resale restriction, no affidavit — and the $50,000 figure is the commercial threshold, which expressly excepts single-family residences. The three homeowner trade exemptions are three differently worded tests, with the HVACR one reaching only an "existing building or structure." § 17-25-510(b)(2) penalizes the owner $100–$400 per day for using a contractor in violation of the chapter. Water well construction is regulated by the Arkansas Natural Resources Commission after Act 691 of 2023 abolished the Commission on Water Well Construction; there is no well permit, and a landowner may drill their own well under § 17-50-108(b). Septic requires ADH approval before construction and a Designated Representative to complete the design, though a homeowner may install the system; § 14-236-104(c)'s ten-acre, 200-foot exemption is current law and absent from the 2024 rule. County permit findings come from each county's own published department list, read in September 2026.

Dollar ranges for permits, impact fees and construction costs in this guide are illustrative planning figures rather than sourced quotes; the ADH septic plan-review fees ($30 to $150 by conditioned square footage) are exact. The Arkansas Energy Code edition is deliberately not stated — no current adopting instrument could be verified. Permit fees, processing times, frost depths, impact fees, and whether any building permit is required at all vary by jurisdiction — verify with your specific county or city building department, and with the Department of Health for the septic permit, which applies either way, before relying on any figure here.
