Unincorporated Loving County, Texas has no building permit requirement and no county zoning office, and Texas law gives Loving County no zoning authority over unincorporated land123. With a population of about 43, Loving County is the least populous county in Texas, and that population falls below the 100-person floor Texas law sets before a county can even opt into its optional residential building-code framework, so that framework isn't available here regardless of whether the county ever adopted it45. Septic is regulated statewide, and TCEQ's own authorized-agent lookup lists Loving County itself as the local agent for the entire county, with OSSF permits administered through the County Judge's office67.

Do you need a building permit in Loving County, Texas?
No building permit is required to build a home on unincorporated land in Loving County; Texas counties generally lack authority to require one, and no county building or permit department has been found for Loving County1. Texas does let some counties opt into a residential building-code subchapter, but only if the county both adopts a resolution or order and is either within 50 miles of the international border or has a population over 100; Loving County's population of about 43 rules that second path out regardless of whether the county has adopted a resolution54. Because that framework isn't in play here, the state's related owner-builder notice exemption for individuals acting as their own contractor is also moot for Loving County construction, since it only applies to projects the residential-code subchapter actually covers11.
Who do you call about building and land use in Loving County?
Loving County's government is based at the Loving County Courthouse in Mentone, the county seat, which houses the County Judge, County Clerk and the other elected county offices12. Since the county lists no building, planning or zoning department, this courthouse is the right first call for any land-use question on unincorporated land121. Septic is different: TCEQ's own authorized-agent lookup lists Loving County itself as the local agent for OSSF permits countywide, and that program is administered through the County Judge's office rather than a separate department76.
Does Loving County have zoning?
Loving County has no zoning ordinance or planning office, and Texas law gives county zoning power only to a handful of specific, narrowly defined areas elsewhere in the state, none of which include Loving County2. 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 Loving County has not published zoning districts3. That absence of zoning is also what makes RV, tiny-home, manufactured-home and accessory-dwelling living, and temporary camping, unrestricted by any county rule on unincorporated land3.
How do septic permits work in Loving County?
A permit is required to construct, install, alter, extend or repair an on-site sewage facility (OSSF) anywhere in Texas, and TCEQ's own authorized-agent lookup lists Loving County itself as the local agent for the entire county, with permits administered through the County Judge's office67. Soils here are a moderate constraint: USDA data rates about 33.1% of Loving County's soils as free of severe limitations for a conventional septic drain field, so roughly two-thirds of the county should expect extra site work or an alternative system8. A single-family home on a tract of 10 acres or more can qualify for Texas's 10-acre OSSF exemption if it also meets every other condition: 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 tract13. If you're buying into a proposed subdivision that draws its water from groundwater, Texas has required a groundwater-availability certification for that subdivision's plat since January 1, 202414.
Can you live in an RV or tiny home on your land in Loving County?
Yes: because Loving 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 too3. Once whatever you place on the land is plumbed, it still needs an OSSF permit through the County Judge's office, Loving County's own listed TCEQ agent, before you can use a septic system76.
Building a home in Loving County: the steps, in order
- Confirm the parcel is unincorporated; Loving County has no incorporated cities, so county rules (or their absence) apply countywide.
- Before you buy, check soil suitability for septic; only about 33.1% of the county's soils carry no severe limitation for a conventional drain field8.
- Apply for your OSSF permit through the Loving County Judge's office, the county's listed TCEQ agent, before installing any septic system, or confirm you qualify for the 10-acre exemption713.
- If you'll drill a well, check whether the parcel falls within a groundwater conservation district; registration and permitting rules apply only if it does9.
- 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 begins15.
- For anything else, start with the Loving County Courthouse12.
What to check before you buy land in Loving County
Water is the central planning question in Loving County: it's very arid, averaging about 11.6 inches of precipitation a year, with severe drought in roughly 23.6% of years, so confirm well capacity and any groundwater conservation district rules before you count on a given yield1016. This is genuinely remote land: Loving County has about 43 residents at a density of roughly 0.1 people per square mile, and it's about 72 miles to the nearest metro area, so plan for long drives to services, fuel and supplies41718. The terrain is flat and open, with all of the county at 15% slope or less and no wooded cover, and there's no federal land here to navigate boundary or access issues around192021. The climate is trending hotter: the county is projected to see about 66.2 days a year at or above 100°F by mid-century, worth factoring into any building or water-storage plan22.
Watch-outs
- We could not confirm whether any groundwater conservation district covers your specific parcel in Loving County; well registration and permitting rules depend entirely on that, so check with the Loving County Courthouse or the Texas Water Development Board before you drill9.
- No official source confirms whether Loving County has adopted a building code, requires inspections, or has a floodplain-development rule; ask the Loving County Courthouse directly before you build1.
