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 systems.
The Wichita County Floodplain Administrator handles county floodplain review for structural development, grading, excavation, drainage work, roads, subdivisions, and individual water or sewer systems1. An applicant gives the project location and legal description and submits the county form before covered work begins1. 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 authority3.
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 homes4. Municipal rules vary across incorporated areas2. The Wichita Falls zoning ordinance applies within that city's incorporated area, where land use and construction must follow the parcel's zoning district2.

County floodplain review can also apply regardless of zoning1.
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 OSSF.
Texas generally requires a permit and approved plan to construct, install, alter, extend, repair, or operate an OSSF6. 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 jurisdiction3. 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 dwelling6. Only about 8.9% of county soils lack severe limitations for a conventional drain field, so settle septic feasibility early7.

County zoning does not restrict RV occupancy, tiny-home occupancy, manufactured-home occupancy, accessory dwellings, or temporary camping on unincorporated Wichita County land4. 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 review1,6. 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 type2,8.

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 contingency7.
