Eastland County also has no countywide zoning ordinance2. For septic, Eastland County Water Supply District is an authorized local OSSF agent within its jurisdiction; TCEQ Region 3 is the fallback elsewhere34.

Do you need a building permit in Eastland County, Texas?
Not for ordinary construction in unincorporated Eastland County: the county's own site lists no building, code-enforcement or permit office, and Texas counties generally have no authority to require prior approval for a house, barn or shed outside a city1. That finding comes from the county's office listing rather than an explicit county statement, so it's worth a confirming call before you break ground. Inside the City of Eastland, the answer flips: the city has adopted the 2018 International Building Code and 2018 International Residential Code as its reference codes and runs its own permit process8. If your land is within the city's extraterritorial jurisdiction, roughly a half-mile band around the city limits, you're still outside city zoning and building permits, but the city does require a plat before you can divide the land9.
How do septic permits work in Eastland County?
Eastland County Water Supply District is a TCEQ-authorized OSSF agent, but the published record does not establish that its jurisdiction covers every parcel in Eastland County3. TCEQ Region 3 in Abilene is the permitting authority wherever no local jurisdiction is authorized, so confirm the parcel's authority before applying410. A permit and approved plan are generally required before constructing, installing, altering, extending, repairing or operating a septic system; qualifying single-family tracts of at least 10 acres and certain emergency repairs have narrow exceptions6. Submit the application and planning materials to the applicable authority, which must approve or deny them within 30 days and explain a denial in writing11. Off-grid systems remain subject to these rules and may accept only domestic sewage12. Only about 2.3% of Eastland County soils avoid severe limits for a conventional drain field, so arrange a site evaluation before committing to a system13. A site in a 100-year floodplain also carries added planning and design requirements14.
Does Eastland County have zoning?
Eastland County has no countywide zoning ordinance2. Because Texas law gives counties zoning power only in narrow, specifically named circumstances that Eastland County doesn't meet, unincorporated Eastland County sets no minimum dwelling size, no setback, no lot-coverage limit and no building-height limit, and does not restrict accessory dwellings, RVs, tiny homes, manufactured homes or temporary camping5. Zoning is strictly a city matter here: the City of Eastland runs its own zoning, specific-use permits, site plans and variance process inside city limits15. The city's subdivision rules reach further, into its extraterritorial jurisdiction about a half-mile beyond the city boundary, reviewing any new plat there for lot size, lot width, street access, utilities, drainage and flood protection, even though the city does not zone that outer band169.
Can you live in an RV or tiny home on your land in Eastland County?
Unincorporated Eastland County has no zoning ordinance, so it places no restriction on occupying an RV, tiny home or manufactured home on your own land, and sets no minimum home size5. Wastewater rules still apply: an off-grid OSSF generally needs a permit and approved plan, may handle only domestic sewage, and can be subject to stricter local requirements12. Eastland County Water Supply District administers OSSF permits within its authorized jurisdiction, while TCEQ Region 3 handles locations without an authorized local jurisdiction34. Confirm which authority covers the parcel before moving in, and arrange the site evaluation early because only about 2.3% of county soils avoid severe limits for a conventional drain field13.
Building a home in Eastland County: the steps, in order
- Confirm your parcel is outside the City of Eastland; if it's within the city's extraterritorial jurisdiction, plan on the city's plat review even though city zoning and building permits don't reach that far9.
- Get a septic site evaluation early, given how little of the county's soil avoids severe drain-field limits, and identify whether the site falls in a 100-year floodplain with added design requirements1314.
- Ask Eastland County Water Supply District whether the parcel lies within its authorized OSSF jurisdiction; if it does not, contact TCEQ Region 3 in Abilene3410. Submit the application and planning materials to the confirmed authority before septic work begins11.
- If the new driveway connects to a state highway, submit TxDOT Form 1058 before construction on the right of way7.
- If you're building inside the City of Eastland, apply for the city's building permit under its adopted 2018 IBC/IRC codes8.
What to check before you buy land in Eastland County
Soils are the single biggest thing to verify before you buy: only about 2.3% of Eastland County's soils are free of severe limits for a conventional septic drain field, so get a site evaluation on the specific parcel rather than assuming standard septic will work13. About a fifth of the county, 21.6%, is wooded, while 94.5% of the land sits at 15% slope or less1718. The county gets 31.1 inches of precipitation a year and sees severe drought in about 26.7% of years1920. The nearest city of 100,000 or more is about 55 miles from the county center21. Property taxes run an effective 1.2% with a median bill around $1,451 a year, and typical home insurance runs about $2,320 a year222324.
Watch-outs
- The 'no building permit' finding for unincorporated Eastland County comes from the county's own office listing showing no building department, not from an explicit county statement that no permit is required; call the County Judge's office to confirm before you build1.
- If your land sits within about a half-mile of the Eastland city limits, you may be inside the city's extraterritorial jurisdiction and subject to its subdivision plat review even though county zoning and building permits don't apply there9.
- Eastland County Water Supply District is an authorized OSSF agent, but its published jurisdiction does not establish coverage of every county parcel; ask the district whether it covers your land, with TCEQ Region 3 as the fallback elsewhere34.
