Unincorporated Burleson County, Texas has no authority to create or enforce building codes and does not require a general building permit for a home1. The one exception is land inside a mapped flood zone, where a floodplain permit is required before construction begins2. Septic is a separate story: Burleson County requires an OSSF permit on every septic system in the county, new or repaired, regardless of how many acres you own3. That's stricter than the standard 10-acre septic exemption Texas law otherwise allows4.

Do you need a building permit in Burleson County, Texas?
No. Unincorporated Burleson County has no authority to create or enforce building codes, and doesn't require building inspections for an ordinary home, cabin, barn or shop1. Texas law generally withholds building-permit authority from counties outside a handful of narrow situations, such as fire-code permits in larger counties covering commercial and multifamily buildings, or residential standards a county adopts by resolution near an international border14. Burleson County has not been shown to have adopted either. The one exception that does apply here: because the county participates in the National Flood Insurance Program, any development within a mapped floodplain needs a permit, approved before construction begins; development outside the floodplain doesn't need one215. If your land is inside the City of Caldwell, Somerville or Snook, that city's building-permit office handles your project instead of the county1.
Who handles building, floodplain and septic permits in Burleson County?
There's no building department to call in unincorporated Burleson County, because the county doesn't run a general building-permit program1. For land in a mapped flood zone, applications, plans and specifications go to the Floodplain Office, Suite 303 of the county courthouse, for review and approval before construction begins1615. Septic systems go through the Burleson County Environmental Department, the county's TCEQ-authorized agent for OSSF permits, also based in Suite 3031718. For a driveway or culvert in the county right-of-way, Road & Bridge issues the access permit and there's no application fee for it; the request is routed through the county's addressing coordinator to whichever commissioner's precinct covers the site1920.
Does Burleson County have zoning?
No countywide zoning ordinance was found for Burleson County; the county's own construction-permits and subdivision pages describe only building-code, floodplain, driveway, utility and OSSF permitting, not zoning districts5. Texas law gives counties zoning power only for a handful of special geographic areas, such as Padre Island beaches, certain military zones and select lakes, and Burleson County is not among them, so the county cannot zone unincorporated land even if it wanted to21. That means unincorporated Burleson County sets no minimum home size, no setbacks, no lot-coverage limit and no building-height limit, and RVs, manufactured homes, accessory dwellings and temporary camping are unrestricted under county rules7. Inside the cities it's a different picture: Caldwell has adopted its own zoning ordinance dividing land into districts such as agricultural, residential, mixed-use and commercial, so land inside Caldwell's city limits follows Caldwell's rules, not the county's6. One county-level rule still reaches unincorporated land regardless of zoning: dividing a tract into two or more parts with streets, alleys or shared-use areas requires a subdivision plat, unless the split qualifies for an exception such as primarily agricultural use, a family transfer of four or fewer parts, or every resulting lot over 10 acres1112.
How do septic permits work in Burleson County?
Every septic system in Burleson County needs an OSSF permit from the county's Environmental Department, the TCEQ-authorized agent for the county, covering new construction, modifications and repairs regardless of acreage317. That's stricter than Texas's usual rule: state law lets a single-family home on 10 acres or more skip OSSF permitting if a licensed site evaluator signs off, the system stays 100 feet from every property line and the dwelling is the only one on the tract, but Burleson County's own order requires a permit on every system no matter how much land you own43. Fees run $330 for a residential system and $540 for commercial; a modification against an existing permit costs $165 residential or $270 commercial, and a repair is $1003. Lot size matters too: the county requires at least 1 acre per single-family dwelling with public water access, or 2 acres with a private well9. Every system needs a construction inspection before the county issues a License to Operate, and an active water connection, well or public supply, is required on the application2223. Soils help explain the strict local rule: only 19.2% of Burleson County's land is free of severe limitations for a conventional drain field, so budget for a site evaluation and possibly an engineered system13.
Can you live in an RV or tiny home on your land in Burleson County?
Outside a zoning ordinance, Burleson County sets no rule limiting how you occupy your own land, so there's no county minimum home size and no county restriction on living in an RV, tiny home or manufactured home on unincorporated property7. That changes once you're inside a dedicated RV park, tiny-home park or campground: those developments must go through the county's subdivision regulations, capped at 15 units per acre, with an approved infrastructure plan required before construction, and a home under 600 square feet on a mobile platform is treated as an RV under those rules8. No official source confirms whether the county requires a certificate of occupancy for a home you build yourself, so confirm with the Environmental Department or Floodplain Office before you assume none is needed17.
Building a home in Burleson County: the steps, in order
First, confirm whether your parcel sits in a mapped flood zone using the FEMA flood map; if it does, submit a floodplain permit application, plans and specifications to the Floodplain Office before starting construction162. Next, order a site and soil evaluation early, since most of the county's soils have real limitations for a conventional drain field13. Then apply for your OSSF permit through the county's Environmental Department before installing a septic system; the county requires a permit on every system regardless of acreage, at $330 residential or $540 commercial173. Confirm your lot meets the county's septic-driven minimum size, 1 acre with public water access or 2 acres on a private well, before you count on building there9. If you're adding a driveway or culvert onto a county road, apply for the Road & Bridge access permit, which carries no fee1920. If your driveway connects to a state highway, apply through the TxDOT district office using Form 1058 and give TxDOT 24-hour notice before work begins24. Finally, build: there's no countywide building-permit review or inspection to schedule for an ordinary single-family home outside the floodplain1.
What to check before you buy land in Burleson County
Water and septic go together here: the county gets about 40.8 inches of rain a year but sees severe drought in 19.5% of years, and with just 19.2% of soils free of severe septic limitations, plan real budget for both a reliable well and a properly engineered system252613. Land is mostly flat, with 99.7% of the county at 15% slope or less, and modest tree cover at 22.3% forested, so building sites are easy to find but shade and windbreaks may need planting2728. Check the FEMA flood map before you buy, since it's the one trigger for a county permit here2. If you're drilling a well, contact the Post Oak Savannah Groundwater Conservation District first: even an exempt domestic or livestock well needs District registration and a Certificate to Proceed with Drilling before you drill29. If the tract you're buying was recently split off a larger parcel, confirm it went through the county's subdivision-plat process or qualified for an exception, since that affects road access and utility easements11. Typical property tax runs about 1% effectively, with a median bill near $1,816 a year, on a typical home value around $271,930303132.
