Washington County Building Department | Permits, Inspections & Contact

Washington County Planning administers land-development approvals in areas outside incorporated city limits. The county’s official planning page specifically says it does not enforce building codes for agricultural buildings, single-family homes, or residential accessory structures in unincorporated areas, so a rural homeowner should not assume that Washington County operates like a city building department. Municipal boundaries and the project’s type determine which permits and reviews apply.

What Washington County Planning handles

The county lists certificate-of-occupancy requests, certified surveys, civil plat review, communication-tower construction permits, floodplain development permits, large-scale developments, lot splits and combinations, subdivisions, and zoning or conditional-use permits among its planning functions. The county’s application materials also cover E911 address review and related land-use submissions. Fees are due to the Planning Department when an application is submitted, and staff asks applicants to provide the property address or parcel number when requesting a pre-application appointment.

Unincorporated residential construction

For an unincorporated single-family home, agricultural building, or residential accessory structure, Washington County says no building permit or inspection is required under the county’s building-code policy, and no certificate of occupancy is issued unless specifically requested. That statement does not eliminate other obligations: zoning, subdivision, floodplain, driveway or culvert, septic, E911 addressing, utility, and state requirements may still apply. If the property is inside Fayetteville, Springdale, Farmington, Prairie Grove, or another municipality, contact that city’s building and planning authority instead.

Zoning, floodplain, and development review

Washington County describes the countywide parcel designation as Agricultural/Single-Family Residential, one unit per acre, but proposed subdivisions, lot changes, conditional uses, large-scale developments, towers, floodplain work, and other land-development activities may require formal review. The county requests surveys certified by an Arkansas-licensed land surveyor when a survey is part of an application, with items such as property boundaries, improvements, septic locations, setbacks, easements, floodplain information, parcel number, acreage, and legal descriptions.
