Do you need a building permit in Bowie County, Texas?
No. Unincorporated Bowie County has no county building-permit program1. Texas counties generally lack authority to require one outside a few narrow, population-gated exceptions8. Building permits in this area come from cities such as Texarkana, so if your land is inside a city's limits rather than the surrounding unincorporated county, check with that city instead1.
Who handles permits and inspections in Bowie County?
There is no county building or planning department for unincorporated Bowie County12. For septic, the Bowie County Health Inspections Department at the Bowie County Courthouse handles OSSF permits directly3. For anything else the county's own pages don't cover, the Bowie County Courthouse is the general point of contact at 903-628-6700, 710 James Bowie Drive, New Boston, TX 755709.
Does Bowie County have zoning?
Bowie County has no county zoning ordinance2. Because Texas gives counties zoning power only in narrow, specifically named circumstances that do not include Bowie County, the county cannot set a minimum lot size, setbacks, a building height limit or zoning districts for unincorporated land6. That same absence of zoning means unincorporated Bowie County places no zoning-based restriction on RVs, tiny homes, manufactured homes or accessory dwellings6. This applies only outside incorporated cities; a city like Texarkana sets its own rules inside its limits.
How do septic permits work in Bowie County?
Bowie County's Health Inspections Department administers OSSF (septic) permits directly, acting as the state's authorized agent rather than routing applications through a TCEQ regional office43. The county publishes an Application on-Site Sewage PDF on the department page10. A permit and approved plan are required to construct, alter, repair, extend or operate an OSSF11, and the county lists a $325 residential fee and a $425 commercial fee as of October 13, 20205. A single-family home on a tract of at least 10 acres can qualify for Texas's 10-acre exemption if every part of the system stays at least 100 feet from the property line and the tract has only that one dwelling12. Only about 11% of Bowie County's mapped soils are free of severe limitations for a conventional septic drain field13, so budget for a site evaluation and possibly an engineered system.
Can you live in an RV or tiny home on your land in Bowie County?
In unincorporated Bowie County, living in an RV or a tiny home on your own land is unrestricted, because the county has no zoning ordinance to set occupancy rules for either6. The same absence of zoning means Bowie County sets no minimum dwelling size for unincorporated land6. This is a county-level answer only: it does not apply inside an incorporated city, and it says nothing about deed restrictions a particular subdivision may carry.
Building a home in Bowie County: the steps, in order
- Confirm your tract is in unincorporated Bowie County rather than inside a city like Texarkana, since a city sets its own permit and zoning rules12.
- Because unincorporated Bowie County has no building permit or zoning requirement, you can generally start planning construction without a county permit12.
- Download the county's Application on-Site Sewage PDF, then work with the Bowie County Health Inspections Department on the OSSF permit and site evaluation10313.
- If the driveway will connect to a state highway, submit TxDOT Form 1058 and do not start work in the right-of-way until the permit is fully executed and TxDOT has received 24-hour notice14.
- For building inspections, occupancy, wells, floodplain development or access from a county road, call the Bowie County Courthouse because we could not confirm the applicable county requirements9.
