Does Prairie Grove, Arkansas have zoning?

Yes. Prairie Grove applies its own zoning districts inside city limits1. The A-1 Agricultural district is one of them, and it is exempt from the city's fence and wall chapter8.

We could not confirm the district-by-district minimum lot sizes, setbacks, building heights or minimum dwelling sizes in the city code, nor whether accessory dwellings or tiny homes are allowed. Ask Prairie Grove city hall's planning office which district a parcel sits in before you buy, and get the dimensional rules for that district in writing. Washington County's lot-size and setback rules apply only to unincorporated land, not inside the city9.

Do you need a building permit in Prairie Grove, and who issues it?

Inside Prairie Grove, the city, not Washington County, is the office to ask. Permits for building, paving, utilities or construction are not issued until the planning commission or planning office approves a landscape site plan2. The city also has a building inspections office, which reviews fence permit applications and performs final inspections10.

We could not confirm a general residential building permit schedule, a certificate-of-occupancy rule or an owner-builder exemption inside the city. Call Prairie Grove city hall before you draw plans. The state's building code still applies statewide11.

How do septic permits work inside Prairie Grove?

Anyone intending to build a septic tank within Prairie Grove must first apply to the city water department superintendent3. The superintendent also inspects and regulates septic tanks, and the tank must follow state board of health recommendations12.

Where a city sewer line runs in an abutting street, alley or right-of-way and sits within 300 feet of the building, the owner must connect within 90 days of official notice7. Privies, cesspools and surface discharge are unlawful, though a septic tank is allowed13.

For soil testing, Washington County's guidance points to health department Designated Representatives; the Washington County Health Department is at14. Washington County's septic authority is the Arkansas Department of Health15. Washington County's farmland and soil picture is county-wide, and about 8.6% of its soils rate "not limited" for a conventional drain field, so expect a site evaluation16.

Can you live in an RV or tent in Prairie Grove?

Occupying a recreational vehicle or motor home in Prairie Grove for more than 14 days in any six-month period requires a permit, and the days need not be consecutive5. Beyond that, occupancy is allowed only as the chapter or a mobile-home or RV park ordinance provides5.

A camping tent may serve as temporary housing for no more than seven consecutive nights, only in backyards in residentially zoned areas6. We could not confirm tiny-home or manufactured-home occupancy rules inside the city; ask city hall.

Building a home in Prairie Grove: the steps, in order

  1. Confirm the parcel is inside Prairie Grove city limits; outside them, the Washington County rules apply instead (see Washington County).
  2. Ask city hall which zoning district the lot is in and what that district allows1.
  3. Get the landscape site plan approved by the planning commission or planning office, which comes before building permits are issued2.
  4. Check whether a city sewer is within 300 feet; if not, apply to the water department superintendent for a septic tank73.
  5. Arrange inspections with the city's building inspections office.

What stays with Washington County, and what to check before you buy

Washington County does not require building permits for single-family homes in unincorporated areas, but that rule stops at the city limits4. County Planning handles unincorporated land at17, and its guidance tells city-limits buyers to contact the city.

A driveway onto a state highway needs a state access permit18. Washington County's effective property tax rate is 0.6%19. Check flood zones too: floodplain rules inside the city were not confirmed, so ask city hall.

Watch-outs

  • Inside Prairie Grove, the county's no-building-permit rule does not apply; the county rule covers unincorporated land only4.
  • We could not confirm Prairie Grove's lot sizes, setbacks, accessory dwelling rules, well permits or floodplain rules; ask city hall before buying1.
  • Septic tanks inside the city need a city application first, and the tank must follow state board of health recommendations3.
