Sebastian County anchors western Arkansas on the Oklahoma border, with about 130,000 residents concentrated in Fort Smith — the state’s third-largest city — and Greenwood. It is one of Arkansas’s split-district counties, with two judicial districts and two county seats, Fort Smith and Greenwood. Most building-permit activity happens inside the cities, which run their own departments.
This guide covers the county’s two-district structure, what it handles in unincorporated areas, how the statewide code applies everywhere, and where the busy city counters are.
This guide covers unincorporated Sebastian County. Fort Smith, Greenwood, Barling, Lavaca and the other cities run their own building departments.
Sebastian County runs on two judicial districts with two county seats — Fort Smith to the north and Greenwood to the south. For builders the practical point is that the busy building counter is in the cities: Fort Smith’s Building Services office handles the largest share, while the county administers unincorporated development. Confirm from the parcel which authority applies.
What requires a building permit in Sebastian County?
The Arkansas Fire Prevention Code applies statewide, including rural and unincorporated land, but building permits are issued locally, where a city or county runs a permit program. Inside unincorporated Sebastian County a permit is required for most construction, alteration, demolition, repair, relocation, change of occupancy and trade work.
Permit required
- New residential and commercial construction, additions, alterations and conversions
- Structural and load-bearing work, foundations, decks, porches, ramps and stairs
- Finishing basements and attics, and any change of use or occupancy
- Electrical service changes, panel work, new circuits, solar and EV charging equipment
- Plumbing alterations, repipes, water heaters, backflow and sewer or gas connections
- HVAC installation and change-out, ductwork and venting; roofing, siding, windows, pools, signs and demolition
Typically exempt
- Painting, wallpapering, tiling, carpeting and cabinet installation
- Minor repairs and finish work replacing materials in kind
- Small accessory structures below the local size threshold, where zoning allows
- Portable equipment or temporary work the adopted code specifically exempts

Which code edition applies
Arkansas’s defining feature is that a mandatory state code reaches every jurisdiction, yet the state issues no local building permit. A city, county or other political subdivision may adopt only the AFPC 2021 as its foundation document, and it may add amendments only where they are more stringent than the state minimum — never less. So the technical standard is uniform across Arkansas, while the fee schedule, submittal process, review turnaround, inspection scheduling and local registration are set by the county.
Arkansas’s building code is the 2021 Arkansas Fire Prevention Code, adopted by the State Fire Marshal and in force statewide since 1 January 2023; building permits are issued locally where a city or county runs a permit program, and the plumbing, gas, mechanical, energy and electrical codes are adopted by separate state agencies.

Who handles permitting in Sebastian County?
In unincorporated areas the county’s Department of Emergency Management administers the 2012 flood damage prevention ordinance and assigns 911 addresses; Fort Smith, Greenwood and the other cities handle their own building permits and inspections.
| Detail | Information |
|---|---|
| Authority | Sebastian County Department of Emergency Management (unincorporated floodplain and 911 addressing) |
| Seats | Fort Smith (Fort Smith district) and Greenwood (Greenwood district) |
| City-limit work | City of Fort Smith Building Services, 623 Garrison Avenue, Suite 405 |
| Fort Smith contact | 479-784-1051 (permits); 479-784-2206 (building services) |
| County reviews | Floodplain and 911 addressing: Department of Emergency Management, 8400 South Zero, Fort Smith 72903 (479-783-3932, Monday to Friday 8am to 5pm) |

Fort Smith enforces the 2021 Arkansas Fire Prevention Code along with the Arkansas plumbing, gas, mechanical, energy and electrical codes, and requires a city business-occupation licence to operate within its jurisdiction, reciprocating with other Arkansas cities where a contractor has no local office. Building permits there are obtained at 623 Garrison Avenue, Suite 405.
Not sure this scope needs a permit?

As always in Arkansas, the statewide code applies regardless of who inspects.
Permit types
Residential permits
Rural residential work starts with addressing, floodplain review and septic before the structure. Inside Fort Smith or Greenwood, the city handles new homes, additions, re-roofs and solar under the 2021 code, with the $2,000 residential licensing threshold catching most jobs.
Commercial permits
Commercial and multi-family work concentrates in Fort Smith and Greenwood, where the cities review and inspect; unincorporated commercial work is a county development matter. Either way it crosses the ACLB commercial threshold of $50,000.
Credentials: three agencies license the trades
Arkansas splits trade licensing across three bodies, so the credential check is not a single lookup. Electrical and HVACR contractors are licensed through the Department of Labor and Licensing; plumbing and gas contractors through the Department of Health; and general contracting through the ACLB. A firm working across trades will hold several credentials from several agencies, and the county will expect each to be current before a permit issues in that firm’s name.
The Arkansas Contractors Licensing Board requires a commercial licence for non-residential work of $50,000 or more and a residential licence for residential work above $2,000; roofers instead need a roofing contractor registration. Contractor licensing in Arkansas
Sebastian County permit costs and fees
Budget the issuing city’s permit and plan-review fees for city-limit work — plus a Fort Smith business-occupation licence there — or the county’s development and floodplain fees for rural work, and separate trade permits in both cases. There is no state permit fee.
Rather talk it over?
Call 1-855-478-4290 →| Fee component | How it works |
|---|---|
| Local building permit | Set by the local adopted schedule, generally by valuation or floor area |
| Local plan review | Charged by the issuing department, commonly due at submission |
| Trade permits | Separate electrical, plumbing, gas and mechanical fees |
| Contractor registration | Local registration fees where a jurisdiction requires them before issuance |
| Floodplain / development | Additional review where a parcel sits in a mapped floodplain or overlay |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
Fee schedules in Arkansas are set locally and revised on each jurisdiction’s own cycle, so a figure quoted from a neighbouring city, an older packet or a national estimator is not a reliable number here. Ask the county for the schedule in force on your filing date, and ask separately about plan review, trade, and any re-inspection or revision charges, which are frequently billed as distinct lines.

Review, corrections and what actually causes delay
Because Arkansas’s technical code is statewide and uniform, correction cycles here tend not to turn on disputed interpretation of the model code. They turn on the local layer and on credentials: a licence in the wrong classification or lapsed; a trade credential from the wrong agency; a floodplain or zoning approval that had to clear first; a submittal that arrived without the sets or forms the county requires. Ask what the local department needs, in what form, before filing.

Inspections in Sebastian County
Standard checkpoints include footing and foundation, framing, rough-in trades, insulation and energy, fire systems on commercial work, and final, with occupancy approval before use. Fort Smith runs a full inspection sequence; the county administers floodplain compliance.
Confirm bookings rather than assuming them, and give the notice the department asks for — an unconfirmed inspection request is a scheduling risk you can remove with one call or visit.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, energy documentation, product listings, any special-inspection reports and your correction responses available on site.

Permit records in Arkansas sit with the local authority that issued them — the county holds the building permit, the inspection history and the certificate of occupancy for work in unincorporated Sebastian County. If you are buying, refinancing or renovating, ask what it holds for the parcel, and confirm that past work was permitted rather than assuming it was.
Confirm the local layer first, then file. The AFPC 2021 sets the technical standard everywhere in Arkansas, but the fee schedule, submittal list, review turnaround and local registration are the county’s to set. Confirm current requirements, fees and review turnaround for your filing date.
These are the primary sources behind this guide. Codes, fee schedules and portal procedures change, and a department’s own published packet can lag a code change — the adopted ordinance governs, not an un-updated handout. Confirm the position for your filing date.
