We could not confirm a general building permit for unincorporated Wichita County, Texas. County floodplain review can end without a floodplain development permit when the administrator finds the site outside a Special Flood Hazard Area, while development in a hazard area follows the county permit process12. Wichita Falls has municipal zoning, and the Health District handles septic permits where it has designated authority34.

Do you need a building permit in Wichita County, Texas?
We could not confirm a general building permit or county-adopted building code for a home in unincorporated Wichita County. The county does require review before covered structural work, grading, excavation, drainage work, roads, subdivisions, or individual water or sewer systems begin2. When the Local Administrator determines that proposed development is outside a Special Flood Hazard Area, the review ends without a county floodplain development permit, although other approvals may still apply1. A project that requires the county floodplain permit is inspected for compliance and needs as-built elevation information before a Certificate of Compliance is issued5.
Who handles floodplain and building permits in Wichita County?
The Wichita County Floodplain Administrator handles county floodplain review for structural development, grading, excavation, drainage work, roads, subdivisions, and individual water or sewer systems132. An applicant gives the project location and legal description and submits the county form before covered work begins14. We could not confirm a current direct phone number, office address, or general county building department, so use the county permit page to confirm the submission route and ask whether the project needs any approval beyond floodplain review. Septic authorization remains separate: the Wichita Falls-Wichita County Public Health District administers OSSF permits where it has designated authority154.
Does Wichita County have zoning?
Unincorporated Wichita County has no county zoning rule setting minimum dwelling size, minimum lot size, setbacks, lot coverage, building height, zoning districts, or occupancy rules for RVs and tiny homes6. Municipal rules vary across incorporated areas7. The Wichita Falls zoning ordinance applies within that city's incorporated area, where land use and construction must follow the parcel's zoning district3. County subdivision regulations are a separate layer: Wichita County identifies regulations dated January 2025, but we could not confirm their specific acreage, road, utility, or filing terms8. County floodplain review can also apply regardless of zoning2.
How do septic permits work in Wichita County?
Texas generally requires a permit and approved plan to construct, install, alter, extend, repair, or operate an OSSF10. The Wichita Falls-Wichita County Public Health District administers OSSF permits and inspections only where it has designated authority, so confirm that the parcel falls within its approved jurisdiction41115. A single-family tract of at least 10 acres qualifies for the state exemption only if every condition is met, including a professional site evaluation, at least 100 feet between every system component and the property line, on-site effluent disposal, and no second dwelling10. Only about 8.9% of county soils lack severe limitations for a conventional drain field, so settle septic feasibility early12.
Can you live in an RV or tiny home on your land in Wichita County?
County zoning does not restrict RV occupancy, tiny-home occupancy, manufactured-home occupancy, accessory dwellings, or temporary camping on unincorporated Wichita County land6. Septic and floodplain rules still constrain an off-grid setup: an OSSF generally needs a permit and approved plan unless every condition of a state exemption is satisfied, and covered site or utility work can require county floodplain review92. Inside Wichita Falls, municipal zoning applies, and an OSSF or other alternative sewage system is routed through the Public Health District and/or Public Works depending on the system type316.
Building a home in Wichita County: the steps, in order
- Establish whether the parcel is unincorporated or inside a municipality; Wichita Falls applies zoning within its incorporated area73.
- Send the project location and legal description to the Wichita County Floodplain Administrator before covered grading, structural work, or utility installation1314.
- Confirm septic jurisdiction with the Wichita Falls-Wichita County Public Health District, then obtain the required OSSF review before construction15410.
- For a private well, confirm whether a groundwater district or local ordinance requires registration or a permit1718.
- Obtain TxDOT approval before building access in a state highway right-of-way19.
- Before dividing land, obtain Wichita County's current subdivision requirements8.
What to check before you buy land in Wichita County
Locate the parcel relative to city limits, mapped flood hazards, subdivision boundaries, and state highways. Municipal zoning varies, and the Wichita Falls ordinance governs only land inside that city's incorporated area73. County floodplain review ends without a floodplain development permit when the Local Administrator determines that a site is outside a Special Flood Hazard Area1. Only about 8.9% of Wichita County soils lack severe limitations for a conventional drain field, so make septic feasibility a contract contingency12. Severe drought occurs in about 40.7% of years, making a dependable water plan especially important20. For a well, confirm the parcel's groundwater-district or local requirements1718.
Watch-outs
- A Wichita Falls address can bring municipal zoning and utility rules that do not apply to unincorporated Wichita County; confirm the jurisdiction before planning an RV, tiny home, or utility connection321.
- Floodplain-permitted projects receive a compliance inspection, but we could not confirm a general county building code, a general certificate of occupancy, or an owner-builder exemption outside that process; ask the Wichita County Floodplain Administrator what applies to the project5.
