Wichita County, TX Building Permits, Zoning & Septic Rules

Unincorporated Wichita County, Texas has no general building-code permit and no county zoning office, since Texas law gives Wichita County no zoning authority over unincorporated land¹². There is a catch: the county's floodplain development permit covers structural development, grading, excavation, drainage work, roads, subdivisions and individual water or sewer systems countywide, and no work of any kind may start until that permit process is resolved³⁴. Septic is handled locally and countywide, not by the state: the Wichita Falls-Wichita County Public Health District is the TCEQ-authorized agent that issues OSSF permits across the whole county⁵⁶.

Do you need a building permit in Wichita County, Texas?

Wichita County has no general building-code permit or inspection department for unincorporated land³. There's a significant exception, though: the county's floodplain development permit process covers structural development, grading, excavation, watercourse alteration, drainage improvements, roads, subdivisions and individual water or sewer systems countywide, and the county's own form states that no work of any kind may start until a permit is issued⁴. That said, if your specific site is not located in a Special Flood Hazard Area, the county's review of your application can end with a determination that no floodplain permit is required for your project, so the practical effect depends on where your parcel sits relative to the mapped floodplain⁴. Once a floodplain permit is issued, it expires if you haven't started work within six months, and it can be revoked, with all work required to stop until it's re-issued⁴.

Who handles floodplain and building permits in Wichita County?

The Wichita County Floodplain Administrator reviews applications for the county's floodplain development permit, covering structural development, grading, excavation, drainage work, roads, subdivisions and individual water or sewer systems¹⁰. Wichita County's own website blocked automated access this session and no recent archive snapshot was available, so we could not confirm a current phone number or office address; call the Wichita County Courthouse in Wichita Falls to reach this office and confirm before you apply.

Does Wichita County have zoning?

Wichita County has no zoning ordinance or planning office; Texas law grants county zoning power only to a handful of specific, narrowly defined areas elsewhere in the state, none of which include Wichita County¹. Because the county has no zoning authority, there's no county minimum dwelling size, no minimum lot size, no setback rule, no lot-coverage limit and no building-height limit, and Wichita County has not published zoning districts². Accessory dwellings, RVs, tiny homes and manufactured homes are unrestricted by county rule on unincorporated land, though the county's floodplain permit still applies if your parcel is in a Special Flood Hazard Area²⁴. The county has also adopted subdivision regulations, dated January 2025, so a parcel that's part of a new subdivision may face its own platting requirements¹¹.

How do septic permits work in Wichita County?

Unlike most rural Texas counties, septic permitting in Wichita County isn't handled by a distant TCEQ regional office: the Wichita Falls-Wichita County Public Health District is the TCEQ-authorized Designated Representative and issues OSSF permits countywide⁵⁶. Soils are a serious constraint here: USDA data rates only about 8.9% of Wichita County's soils as free of severe limitations for a conventional septic drain field, so plan on a site evaluation and likely an engineered or alternative system for most parcels⁷. Texas's statewide 10-acre OSSF exemption can still apply on a large enough tract if every condition is met: a licensed site evaluator's or engineer's evaluation, no nuisance or groundwater pollution, every part of the system at least 100 feet from the property line, effluent kept on the property, and no other dwelling on the tract¹².

Can you live in an RV or tiny home on your land in Wichita County?

Yes, on unincorporated land: because Wichita County has no zoning authority, RV, tiny-home and manufactured-home occupancy on your own private land is unrestricted by any county rule, and temporary camping is unrestricted too². Whatever you place on the land, once it's plumbed it still needs an OSSF permit from the Wichita Falls-Wichita County Public Health District, and if the parcel sits in a Special Flood Hazard Area you'll also need to work through the county's floodplain permit process first⁶⁴.

Building a home in Wichita County: the steps, in order

Confirm the parcel is outside Wichita Falls, Burkburnett, Iowa Park or another incorporated city, since those set their own rules separate from the county.
Check with the Wichita County Floodplain Administrator whether your site is in a Special Flood Hazard Area; if it is, you'll need a floodplain development permit before any grading, structural work or utility installation, and that permit expires if work hasn't started within six months¹⁰⁴.
Before you buy, get a septic site evaluation; only about 8.9% of the county's soils carry no severe limitation for a conventional system⁷⁶.
Apply for your OSSF permit through the Wichita Falls-Wichita County Public Health District before installing any septic system⁶⁵.
If your driveway will connect to a state highway, contact the local TxDOT district office and submit Form 1058 before any right-of-way work begins¹³.
If your land is part of a subdivision platted since January 2025, confirm the applicable subdivision regulations before you build¹¹.

What to check before you buy land in Wichita County

Septic soils are the headline issue: only about 8.9% of Wichita County's soils carry no severe limitation for a conventional drain field, so budget for a site evaluation and possibly an alternative system before you commit to a parcel⁷. Ask whether the parcel sits in a Special Flood Hazard Area, since that determines whether the county's floodplain development permit applies to your project at all⁴. This is one of the more populated and connected counties in this guide series: about 207.4 people per square mile and roughly 10 miles from the nearest metro area, with severe drought in about 40.7% of years¹⁴¹⁵¹⁶. Federal land is minimal at about 1.1% of the county, and only about 6.1% is wooded¹⁷¹⁸. Property taxes run about 1.8% effective, with a median bill around $2,501 a year, and a typical home insurance premium here is about $2,615 a year⁸⁹¹⁹.

Watch-outs

Wichita County's own website (wichitacountytx.com) blocked automated access this session and had no recent archive.org snapshot, so we could not confirm a current phone number or office address for the Floodplain Administrator; confirm contact details before you apply¹⁰.
We could not confirm whether Wichita County requires building inspections or a certificate of occupancy outside the floodplain-permit process, or whether an owner-builder exemption applies; ask the county directly before you build³.
