Unincorporated Saline County, Arkansas has no countywide building-permit program: the county's only land-use body, the Saline County Planning Board, oversees subdivision rules, not building permits or zoning1. There's also no countywide zoning ordinance for unincorporated land2. If your land is part of a subdivision, though, the Planning Board's own rules do reach you — they set a minimum lot size for septic-served lots and require plats to go through the Board before land is split or sold34. Septic itself is a state matter, permitted through the Arkansas Department of Health's Saline County Local Health Unit in Benton56.

Do you need a building permit in Saline County, Arkansas?
No, not from the county. Saline County's only land-development body is the Planning Board, and it oversees subdivision rules and regulations, not a residential building-permit program1. That's consistent with most rural Arkansas counties, which have the legal option to adopt a permit program but haven't1. The Arkansas Fire Prevention Code, including its residential volume, still applies statewide as a compliance standard "even in areas when no permit or inspections are required," so the code itself governs construction quality even where no county office checks for it10. Keep in mind Saline County is more built-up than many rural counties in this guide series, with a population near 130,000 and density around 179 people per square mile, so confirm your parcel is genuinely unincorporated before assuming county rules (or the lack of them) apply1112.
Who handles land questions in Saline County, and how do you reach them?
There's no county building department to call, because Saline County doesn't run one1. If your land is being subdivided, sold as part of a new subdivision, or platted, the Saline County Planning Board is the office, reachable at (501) 303-5690 or from its office at the Saline County Road Department in Benton13. For septic, the office is the Arkansas Department of Health's Saline County Local Health Unit, also in Benton1415. If your driveway will connect to a state highway, that's a separate process: the Arkansas Department of Transportation requires its own permit before any access driveway is built, reconstructed or modified on state highway right-of-way16.
Does Saline County have zoning?
No countywide zoning ordinance was found for unincorporated Saline County — the Planning Board's own authority is limited to subdivision rules, not zoning districts, setbacks or land-use categories across the county2. That's genuinely unconfirmed territory, not a green light: no official Saline County source states a minimum lot size, setback, building-height limit or minimum dwelling size for unincorporated land outside a subdivision, and none addresses RV, tiny-home or manufactured-home occupancy on an individual parcel2. Where the Planning Board's rules do reach unincorporated land is subdivisions: a subdivider must submit plats to the Board, can't begin most construction before a Certificate of Preliminary Plat Approval, and can't convey title to lots before a Certificate of Final Plat Approval is recorded with the Circuit Clerk3. If your parcel was created as part of a subdivision, those rules may already apply to it even without countywide zoning.
How do septic permits work in Saline County?
Every onsite wastewater system in Saline County needs construction and operation permits before installation, issued under Arkansas Department of Health rules through the Saline County Local Health Unit614. Once installed, the system must be inspected and approved, with the owner obtaining a permit for operation before use17. Soils are a serious constraint here: only about 4.9% of Saline County's land is free of severe limitations for a conventional drain field, among the more difficult counties tracked for this guide, so budget for a site evaluation and likely an alternative system9. If your lot is inside a Planning Board subdivision and served by a septic tank, the Board's own rules set a 20,000-square-foot minimum lot size, conditioned on the Health Department approving the percolation reports, plus a 10-foot side-yard clearance for septic-tank pump-truck access4. If a sanitary sewer is available within 300 feet of the building and reachable without crossing another person's property, state rule requires connecting to it instead of installing an onsite system18.
Can you live in an RV or tiny home on your land in Saline County?
This isn't confirmed by an official Saline County source for an individual parcel, and the lack of countywide zoning shouldn't be read as an answer either way — no county page addresses RV, tiny-home or manufactured-home occupancy on your own unincorporated land outside a subdivision2. What is confirmed is narrower: Arkansas regulates mobile-home and RV parks (three or more spaces, with placement or maintenance services provided for a fee) as a distinct category requiring Department of Health approval before construction, and within a qualifying park, mobile homes must keep at least 20 feet of separation from each other and from internal service easements1920. None of that answers whether you can park an RV or place a tiny home on your own individual unincorporated parcel outside a park — call the Planning Board to ask directly before you commit to living in one full-time13.
Building a home in Saline County: the steps, in order
- Confirm your parcel is unincorporated and, if it's part of a subdivision, whether it falls under Planning Board jurisdiction — land outside incorporated areas and outside a city's extraterritorial planning jurisdiction3.
- Get a soil evaluation early. With only about 4.9% of the county's soils free of severe septic limitations, plan for the real possibility of an alternative system9.
- If you're creating or buying into a new subdivision, check the Planning Board's plat-approval status before relying on lot boundaries or minimum lot sizes133.
- Apply for an onsite wastewater permit with the Saline County Local Health Unit before construction begins146.
- Schedule your installation inspection and get your permit for operation before using the system17.
- If your access is a state highway, apply for an Arkansas DOT driveway permit before starting any work in the right-of-way16.
- Build. Because there's no county building department, there's no county building permit, inspection or certificate of occupancy to schedule for a single-family home outside a municipality and outside subdivision-specific requirements1.
What to check before you buy land in Saline County
Confirm whether the parcel is unincorporated, and if it's part of a platted subdivision, whether the Planning Board's rules — including the 20,000-square-foot septic-lot minimum — already apply to it4. Get a soil evaluation before you count on a conventional septic field: with only about 4.9% of the county's soils free of severe limitations, an alternative system is the likely outcome on most parcels9. Because Saline County is one of the more populated counties in this guide series — about 130,000 people, with a metro area roughly 20 miles away — expect more competition for buildable rural land and higher typical home values than in more remote counties112122. Ask about access: a driveway onto a state highway needs an Arkansas DOT permit before any work begins16. And budget for property tax: Saline County's effective rate is about 0.6%, with a median annual bill near $1,3352324.
Watch-outs
- No official Saline County source confirms or denies a rule on RV occupancy, temporary camping, tiny-home occupancy or manufactured-home occupancy for an individual unincorporated parcel outside a subdivision or park — call the Planning Board before you build or move onto a parcel2.
- Saline County's soils are among the tougher ones tracked for septic: only about 4.9% are free of severe limitations for a conventional drain field, so plan and budget for an alternative system before you commit to a site9.
