Building permits, zoning and septic rules in Schleicher County, Texas

Schleicher County publishes an unusually direct answer: its own Permits & Regulations page states that four items -- subdivision regulations, a county-road pipeline/utility crossing permit, an access-driveway permit, and septic tank permits -- are the only permits and regulations the county has in place¹. A residential building permit is not one of them, so building a home in unincorporated Schleicher County does not require a county building permit¹. Because there is no permit to get, there is also no permit to be exempt from: you may build your own home as an owner-builder in unincorporated Schleicher County¹. State licensing for electrical, plumbing and HVAC trades can still apply even without a county building permit¹.

The Schleicher County Judge's office handles questions about the county's permits and regulations, including septic, driveway and utility-crossing permits¹. Email questions to cjassistant@co.schleicher.tx.us or call 325-853-2593; the office is at the Schleicher County Courthouse, 2 S. Divide, Eldorado, TX 76936¹. For a driveway or culvert permit specifically, the application goes to the Commissioners Court, and the precinct commissioner confirms the correct culvert size^1,5. For a driveway onto a state highway instead of a county road, contact the local TxDOT district office and file Form 1058⁶.

Unincorporated Schleicher County has no countywide zoning: the county's own Permits & Regulations page lists its only permits and regulations, and a zoning ordinance is not among them¹. Because the county has no zoning authority over unincorporated land, it sets no minimum lot size, no setbacks, no lot-coverage limit, no building-height limit and no zoning districts, and RVs, tiny homes and manufactured homes are unrestricted by county zoning⁴. That is a real answer, not a research gap: it follows directly from Texas law giving a county like Schleicher no general zoning power, and Schleicher County's own page confirms it⁴. Inside the City of Eldorado the answer differs: the city applies zoning-related setbacks and variances, with a non-refundable $50 variance fee and a City Council hearing, and those rules do not reach unincorporated land². This guide otherwise covers unincorporated Schleicher County.

Every on-site sewage facility in Texas needs a permit and an approved plan before construction, alteration, repair or extension, with one narrow exception⁷. The exception is a "10-acre rule": a single-family home on at least 10 acres, evaluated by a licensed site evaluator or professional engineer, with every part of the OSSF at least 100 feet from the property line, no other dwelling on the tract, and no nuisance or groundwater pollution⁷. The Schleicher County Authorized Agent is current with TCEQ and serves the entire county except the City of Eldorado, so septic applications for unincorporated land go through the county rather than a TCEQ regional office³. We could not confirm who permits septic systems inside Eldorado, so ask the County Judge's office or the city before buying there¹. An emergency repair does not need a permit first, but it must be reported in writing to the permitting authority within 72 hours after work begins⁷. Plan carefully here: none of Schleicher County's soils are free of severe limits for a conventional septic drain field, so expect to need an engineered or alternative system almost everywhere in the county⁸.

Yes, with conditions: unincorporated Schleicher County has no zoning ordinance, so it sets no rule restricting RV, tiny-home or manufactured-home occupancy on private land, a direct result of Texas law giving the county no general zoning power⁴. The same lack of zoning means there is no minimum dwelling size and no accessory-dwelling rule in unincorporated Schleicher County⁴. Any wastewater system connected to the RV, tiny home or manufactured home still needs an OSSF permit through the county's own TCEQ-authorized program^3,7. And any new driveway or culvert onto a county road still needs a Commissioners Court permit, whatever kind of home it serves⁵.

1. Confirm the parcel is in unincorporated Schleicher County rather than inside Eldorado city limits; this guide covers the unincorporated county, where the county itself has no zoning and no building-permit requirement¹.
2. Email cjassistant@co.schleicher.tx.us or call 325-853-2593 with any permits question -- the County Judge's office handles septic, driveway and utility-crossing permits for Schleicher County¹.
3. Building a new entry from a county road that needs ditch work or a culvert? Submit an application to the Commissioners Court, and confirm the culvert size with your precinct commissioner⁵.
4. Start construction within six months of that driveway permit's issuance, or it becomes void; give the county at least 24 hours' notice before you begin the authorized work⁵.
5. Building a driveway onto a state highway instead? File TxDOT Form 1058 and give 24 hours' notice before construction⁶.
6. Get your septic (OSSF) plan approved and permitted through Schleicher County's own TCEQ-authorized program before you dig^3,7.
7. No county building permit is required for the home itself, and as an owner-builder you may do the construction yourself, though state trade licensing can still apply to electrical, plumbing and HVAC work¹.

Septic is the biggest constraint to plan around: none of Schleicher County's soils are free of severe limits for a conventional drain field, so budget for an engineered or alternative OSSF system on essentially any parcel⁸. The land itself is gentle and open -- 99% sits at 15% slope or less, with only 4.4% wooded -- and the county sees severe drought in about 23.4% of years, worth planning for with any well⁸. Schleicher County is rural and remote, with 2,391 residents at about 1.8 people per square mile, roughly 118 miles from the nearest metro area⁸. Any new driveway or culvert onto a county road needs a Commissioners Court permit, and the county can charge up to $500 to fix an improperly built one if you don't address it within 10 days of written notice⁵. Property taxes run an effective 1.4% rate, with a median annual bill of $1,621⁸.
