Unincorporated Jones County, Texas has no county building-permit requirement and no zoning ordinance, because Texas gives counties zoning and building authority only in narrow situations that don't apply here123. Septic systems go through Jones County's own on-site sewage facility (OSSF) program, since the county acts as TCEQ's authorized agent4. Because the county has no zoning, no county rule restricts RV living, tiny homes or manufactured homes on your own land, though septic permitting and other requirements still apply3.

Do you need a building permit in Jones County, Texas?
Unincorporated Jones County has no county building-permit requirement1. Texas law gives building- and fire-code authority to counties only above a 250,000-population threshold, or to a county adjacent to one; Jones County's population of 20,381 falls well short of that mark, so the county has no general building-permit program89. The county's own website lists no building department or code-enforcement office among its County Offices1011. That doesn't mean nothing is regulated: septic systems and driveways onto state highways still carry their own requirements, covered below4.
Who do you call in Jones County if there's no building department?
Jones County has no building or planning department, so there's no single permit office to call before you build1. The County Judge's Office, based at the Jones County Courthouse in Anson, oversees county administration and the Commissioners Court, and is the right office to ask about floodplain administration or any countywide construction rule that isn't posted online10. The County Clerk's Office, also at the courthouse, handles land records, plat filings and elections, and is where a subdivision plat gets recorded11. Neither office reviews building plans or issues a construction permit, because unincorporated Jones County doesn't run that program1.
Does Jones County have zoning?
Jones County has no county zoning ordinance, and no zoning or planning office is listed on the county's website2. Texas law gives counties general zoning authority only in narrowly defined areas, such as parts of Padre Island in Cameron or Willacy County, that have nothing to do with Jones County5. Because Jones County has no zoning authority, there's no county rule setting minimum lot size, setbacks, lot coverage, building height or accessory-dwelling limits on unincorporated land, and the county doesn't restrict living in an RV, tiny home or manufactured home either3. That's a direct result of Texas law giving the county no zoning power here, not a gap in what's been researched3. Jones County's cities, including Anson, Hamlin and Stamford, can set their own zoning within their own city limits, separate from the county.
How do septic and well permits work in Jones County?
On-site sewage facilities (septic systems) in Jones County go through the county's own OSSF program, since Jones County acts as TCEQ's authorized agent rather than routing permits through a TCEQ regional office4. Every OSSF in Jones County requires a permit before construction, installation, repair or alteration, with a residential permit application fee of $450 plus a $10 state research fee, for a total of $4606. Statewide, Texas allows a limited exemption from the septic-permit requirement on tracts of at least 10 acres, but only if every condition is met: a licensed site evaluator signs off, it's a single-family home, all parts of the system sit at least 100 feet from the property line, and the tract has no other dwelling12. Jones County has no published rule on private water wells; ask the County Clerk's Office or County Judge's Office to confirm whether your specific location falls inside a groundwater conservation district before you drill1110.
Can you live in an RV or tiny home on your land in Jones County?
Jones County has no zoning ordinance, so there's no county rule restricting RV living, tiny homes or manufactured homes on your own land3. That's a real answer, not just an absence of research: Texas law gives Jones County no zoning power to regulate these uses in the first place3. Statewide rules about licensed RV parks and campgrounds don't apply to living in your own RV on your own land, so don't read those as a limit here. Whatever dwelling you choose, its septic system still needs a Jones County OSSF permit, since that requirement doesn't depend on the structure being a conventional house4. If your land sits inside Anson, Hamlin, Stamford or another Jones County city rather than the unincorporated county, that city's own rules would apply instead2.
Building a home in Jones County: the steps, in order
- Confirm your parcel is in unincorporated Jones County rather than inside a city, since city rules can differ from the county's2.
- Call the Jones County Judge's Office to confirm current floodplain status and any other county requirements for your specific parcel before you break ground10.
- Apply for a Jones County on-site sewage facility (OSSF) permit before you design your septic system; the residential application fee is $450 plus a $10 state research fee6.
- If your tract is at least 10 acres, have a licensed site evaluator confirm in writing whether you qualify for the state's septic-permit exemption, since every condition has to be met12.
- If you're adding or changing access onto a state highway, submit TxDOT Form 1058 and wait for a fully executed permit before starting work13.
- If you're subdividing the land, check the county's subdivision regulations and file the plat with the Jones County Clerk's Office11.

Watch-outs
- Jones County's Commissioners Court has discussed floodplain-management administration in official meeting minutes, but no official Jones County page spells out the floodplain rules that would apply to your parcel; confirm current floodplain status with the County Judge's Office before you build10.
- The County Judge's Office and the county's septic-permit program both list the same P.O. Box 148 mailing address in Anson; that's normal for a small county with one courthouse, not a sign you have the wrong office106.
- Several other U.S. counties are also named Jones County; confirm any result you find online names Jones County, Texas specifically before you rely on it2.
