Building permits, zoning and land rules in Wise County, Texas

Wise County does not require a general building permit outside incorporated cities and their extraterritorial jurisdictions; contact City Hall for parcels in either area¹. An owner-builder may build a home without a county building permit, although state licensing may still apply to electrical, plumbing, and HVAC work¹. Municipal building-permit offices serve Decatur⁷, Bridgeport⁸, Runaway Bay⁹, Rhome¹⁰, New Fairview¹¹, Aurora¹², Town of Alvord¹³, Newark¹⁴, Paradise¹⁵. Wise County Public Works handles septic permits on unincorporated land; city septic authority needs a separate check, as Bridgeport administers a municipal OSSF program^3,16.

For septic permits on unincorporated Wise County land, call Environmental Services (Public Works) at 940-627-9332^1,3. For county-road, drainage, subdivision, or plat questions, contact the Wise County Engineer at (940) 273-7289¹⁷. Construction in an unincorporated floodplain requires a floodplain development permit from the Wise County Floodplain Administrator before work begins⁴. Wise County directs applicants in cities or extraterritorial jurisdictions to City Hall for building-permit information¹.

Unincorporated Wise County has no county zoning ordinance¹. Municipal zoning applies inside Decatur², Bridgeport¹⁸, Runaway Bay¹⁹, Rhome²⁰, Town of Boyd²¹, New Fairview¹¹, Aurora²², Town of Alvord¹³, Newark¹⁴, Paradise¹⁵. Decatur adopted its zoning ordinance in 2015; allowable uses remain subject to that ordinance and related development rules². County septic permits still apply on unincorporated land, while New Fairview and Aurora administer municipal OSSF rules inside their limits^3,23,24. The absence of county zoning does not eliminate subdivision or floodplain requirements^4,6.

On-site sewage facilities in unincorporated Wise County require a septic permit through Public Works³. Submit the application, site evaluation, required planning materials, and applicable fee, then obtain an Authorization to Construct before installing the system¹. Wise County requires an OSSF permit even on tracts of 10 acres or more⁴. Subdivision lots using septic need at least 1 acre with public water or 2 acres with an individual water system⁴. Only 24% of county soils are rated without severe limitations for conventional drain fields, making site evaluation an early feasibility check²⁵. Inside cities, confirm the septic authority separately: Bridgeport, New Fairview, and Aurora have municipal OSSF programs^16,23,24. Tarrant Regional Water District requires OSSF permits on Lake Bridgeport land subject to its Waste Control Order; that does not establish district jurisdiction over every city parcel²⁶.

Wise County does not use county zoning to set minimum dwelling size, setbacks, lot coverage, building height, or occupancy restrictions for RVs, tiny homes, manufactured homes, accessory dwellings, or temporary camping on unincorporated land⁵. Septic installation still requires a county permit and an Authorization to Construct^3,4. Subdivisions require public water unless connection is infeasible and the county allows qualifying private wells; that rule does not require every existing rural parcel to connect to public utilities⁴. Inside Decatur, ask City Hall about the proposed use under city zoning rather than applying the unincorporated-county answer².

1. Confirm whether the parcel is in unincorporated Wise County, a city, or an ETJ; contact City Hall for building-permit information¹.
2. For unincorporated land, proceed without a general county building permit¹.
3. Check the flood map early; construction in an unincorporated floodplain requires a floodplain development permit from the Wise County Floodplain Administrator⁴.
4. Call Wise County Environmental Services at 940-627-9332, submit the site evaluation and planning materials, and obtain an Authorization to Construct before installing septic^1,4.
5. If the project divides land, ask the County Engineer about plat review and published subdivision fees⁶.
6. For a subdivision, plan for public water unless connection is infeasible and the county approves qualifying private wells⁴.
7. If the driveway connects to a state highway, submit the state driveway permit application before construction²⁷.

Before buying land to divide for farming or ranching, ask the Wise County Engineer whether the agricultural platting exemption applies^6,17. A qualifying division outside municipal limits may avoid platting if the land remains primarily in agricultural, farm, ranch, wildlife-management, or timber-production use and no streets or other areas for public or lot-owner use are laid out; platting requirements apply if qualifying use ends⁶. The exemption does not waive septic or other development requirements⁶. For regulated subdivisions, published fees include $800 plus $100 per lot for a preliminary plat and $750 for a final plat without roads; confirm current charges with the County Engineer^6,17. Check wastewater feasibility, subdivision water supply, and flood status before committing to a homesite^4,25. Wise County’s effective property-tax rate is about 1.2%, and its median annual property-tax bill is $3,293²⁵.
