Which Texas counties don't require a building permit?

Texas has 164 counties without a residential building permit requirement, 77 with requirements limited to particular cases, and 13 with a building permit requirement.¹⁶⁷ Start with Cherokee County, Sabine County and Angelina County, which fall in the no-residential-building-permit group.¹ Browse the Texas no-building-codes list for the full comparison.¹

A missing building permit requirement does not establish an exemption from construction standards: Texas county residential-code authority can apply without authorizing prior approval of new residential construction.¹³ Texas also has mandatory codes specifically for industrialized housing and buildings; that program is not a universal code adoption for all site-built construction.¹⁴ Owner-performed electrical work has a state licensing exemption only for a dwelling the owner owns and resides in, and local building permits or inspections are not waived.¹¹

Which Texas counties have no zoning?

Texas has 246 counties without countywide zoning, while 8 counties have zoning in applicable areas.²⁸ Cherokee County, Sabine County and Angelina County are among the counties without countywide zoning.² Texas county zoning authority is geographically or subject-matter limited, rather than a general statewide grant of county zoning power.¹⁵

For buyers seeking both conditions, 158 Texas counties have neither a residential building permit requirement nor countywide zoning.⁹ Use the no-zoning list and the no-building-codes and no-zoning list to narrow your search.²⁹ Septic approval remains a separate question, because Texas generally requires an OSSF permit and approved plan even where a county does not require a residential building permit.¹⁶¹

Who issues septic permits in Texas?

Texas septic authority is split among county offices in 189 counties, districts in 19, and state offices in 46.¹⁷ Local TCEQ-authorized agents administer most septic permitting; TCEQ regional offices issue septic permits where no local jurisdiction is authorized, and local programs may be stricter than state minimums.³ The TCEQ OSSF contacts page links to the local permitting authority lookup.¹⁸

Texas generally requires a permit and approved plan to construct, alter, repair, extend or operate an OSSF.¹⁶ The exemption for a tract of at least 10 acres requires a licensed site evaluator or professional engineer, only a single-family dwelling on the tract, no nuisance or groundwater pollution, disposal on the property, and all system parts at least 100 feet from the property line, along with applicable planning and construction standards.¹⁹ Ask the identified septic permitting authority to confirm exemption eligibility and the application fee before budgeting for wastewater approval.³

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

Texas RV occupancy answers cover 227 counties: 219 allow it, 7 impose limits and 1 prohibits it; 27 counties remain unanswered.⁴ Tiny-home occupancy answers cover 231 counties: 228 allow it and 3 impose limits, with 23 unanswered.⁵ An unanswered county is not an allowance or a prohibition.⁴⁵

Cherokee County, Sabine County and Angelina County are listed as allowing RV occupancy, with answers scoped to county zoning restrictions on unincorporated land.⁴ Those counties also have allowing answers for tiny-home occupancy under the same county-zoning scope.⁵ Compare the RV-living list and tiny-home list before choosing a county.⁴⁵ Off-grid wastewater still generally requires an OSSF permit and approved plan; choosing an RV or small dwelling does not establish a sanitation exemption.²⁰

Where are the best Texas counties for a bolthole?

Cherokee County and Sabine County lead the Texas Bolthole Index at 88, followed by Angelina County and Jasper County at 87.²¹ These counties have no residential building permit requirement and no countywide zoning; Cherokee and Sabine use county septic authorities, while Angelina and Jasper use district authorities.²¹

Across Texas counties, the median county farmland value is $2,782 per acre; that is an agricultural land-value measure rather than a price quote for a particular building tract.²² Roberts County has the lowest listed farmland value at $950 per acre, followed by Val Verde County at $1,000.²² The median county effective property tax rate is 1.25%, and the median county property tax bill is $1,875 annually; these county medians do not establish a particular parcel’s tax bill.²³

What should you check about Texas water, wells and highway access?

Texas combines surface-water appropriation and riparian or vested rights with the groundwater rule of capture.²⁴ Groundwater conservation districts generally require well permits unless an exemption applies; a particular well’s exemption and additional requirements depend on district rules.¹² A domestic or livestock well on more than 10 acres producing no more than 25,000 gallons per day has a groundwater-district production-permit exemption, but spacing and registration requirements may still apply.²⁴ Ask the applicable groundwater conservation district about the proposed well before arranging drilling.¹²

For a new or revised driveway onto state highway right of way, contact the local TxDOT district office and submit Form 1058, Permit to Construct Access Driveway Facilities on Highway Right of Way.²⁵ Construction on the right of way must wait for a fully executed driveway permit and advance notification to TxDOT of 24 hours.²⁵

Watch-outs

• The county building-permit counts apply to unincorporated land; city rules differ, and a municipal building code can control in the city’s extraterritorial jurisdiction.¹¹³
• Counties with limited building-permit requirements are a separate group; do not treat their development or floodplain approvals as no building permit requirement.⁶
• Texas septic permitting and local requirements remain separate from a county’s residential building permit answer.¹⁶³
• TDLR’s industrialized housing installation-permit option is for a purchaser or lessee’s own use; assembly for other people requires industrialized-builder registration.²⁶
