Building permits, zoning and land rules in Fisher County, Texas

Fisher County's official website lists no building or permit department, and Texas counties generally lack authority to require residential building permits outside incorporated cities, so the best current answer is that unincorporated Fisher County does not require one¹. That answer comes with a real caveat: Texas law lets a county add residential building-code enforcement by adopting a resolution or order under Local Government Code Section 233.152, and no official Fisher County resolution or order confirming or ruling out that adoption was found⁶. Fisher County's population is about 3,600, far under the 250,000-person threshold that would let it adopt a fire code tied to commercial or multifamily construction on its own, so that separate authority does not apply here regardless^6,7. Call the County Judge's office at 325-776-2151 before you build to confirm neither rule has changed, since no dedicated department was found to ask instead³.

Fisher County has no building, zoning or floodplain department listed on its official site, which is common for a rural Texas county this size¹. The offices that do exist, and that a land buyer is most likely to need, are the County Judge's office, which presides over the Commissioners Court and handles the county's administrative functions, and the County Clerk's office, which records deeds, plats and other land records^3,8. The County Judge's office and Commissioners Court share the Fisher County Courthouse at 112 N Concho St in Roby, and can be reached at 325-776-2151 or info@fishercounty.org³. The County Clerk's office is physically at 109 N. Angelo, but mail must go to PO Box 368, Roby, TX 79543, since the Post Office does not deliver to the street address; the Clerk's office can be reached at 325-776-2401⁸. Property tax questions go to the Tax Assessor-Collector at PO Box 278, 100 N. Concho, Roby, TX 79543, phone 325-776-2181⁹.

No zoning or land-use department is listed on Fisher County's official site, and Texas counties generally cannot zone unincorporated land, so the best current answer is that Fisher County has no zoning¹. Because no zoning ordinance was found, accessory dwellings, RVs used as housing, tiny homes, manufactured homes, minimum lot size and setbacks are all unrestricted by county zoning as far as we could confirm². This is a rural-county default, not a re-verified ordinance search of every Fisher County record, so a buyer with a specific plan should still confirm with the County Judge's office that nothing has changed³. Subdivision plats and any recorded deed restriction, which a lack of zoning does not override, are filed with the County Clerk⁸. Texas requires a plat when an owner divides a tract to lay out lots or a subdivision outside city limits, though land used primarily for agricultural use is excepted from the county plat requirement while it stays in that use^10,11.

Every on-site sewage facility (OSSF, commonly called a septic system) in Texas needs a permit before construction, alteration or repair, and Fisher County has no local program evident to issue it, so the TCEQ regional office is the current best answer for where that permit comes from⁴. Under Texas rules the TCEQ regional office is the permitting authority only where no local jurisdiction has been authorized⁴. That finding is a default, not a confirmed local authorized-agent lookup: no Fisher County department or TCEQ authorized-agent listing specific to the county was located, so a buyer should call TCEQ directly to confirm before assuming no local agent exists⁴. If the permit is issued by an authority that allows it, an owner may install the system on their own single-family home, provided the owner owns the property, the property is not developed for sale or lease, and any helper is a licensed installer⁴. A 10-acre exemption can remove the permit requirement, but only if every condition is met: a site evaluation by a licensed evaluator or engineer, a single-family home on at least 10 acres with no other dwelling on the tract, no nuisance or groundwater pollution, and every part of the system kept at least 100 feet from the property line⁴. Soils help the odds here: about 36% of Fisher County's land is rated free of severe limits for a conventional septic drain field, well above many rural counties, though a site evaluation still confirms the specific parcel⁷.

As far as we could confirm, living in an RV or tiny home on unincorporated land in Fisher County is unrestricted by county zoning, since no zoning ordinance was located². That is a zoning-only answer, and it rests on the absence of a rule rather than a confirmed ordinance search of every Fisher County record, so a buyer with a specific plan should still call the County Judge's office before relying on it³. An RV or tiny home with a bathroom or kitchen sink still needs an OSSF permit once it is used as a residence, the same as a house, most likely through the TCEQ regional office given the county's apparent lack of a local authorized agent⁴.

1. Call the County Judge's office at 325-776-2151 to confirm current building and floodplain rules before you finalize plans, since no dedicated department publishes them online³.
2. Check the deed and any recorded plat at the County Clerk's office, 325-776-2401, since Fisher County has no zoning to fall back on⁸.
3. If the site will use a septic system, contact the TCEQ regional office to confirm the permitting authority and apply for an OSSF permit before construction begins⁴.
4. Get a site evaluation to confirm your specific soils; about 36% of the county's land is rated free of severe limits for a conventional drain field, a better starting point than many rural counties⁷.
5. If the driveway connects to a state highway, contact the local TxDOT district office and get a TxDOT Form 1058 permit before construction begins⁵.
6. Confirm your property tax account with the Tax Assessor-Collector at 325-776-2181 before closing⁹.
7. Because no county building code was confirmed either way, line up your own inspector or engineer for plumbing, electrical and structural work if you want that assurance¹.

Fisher County is dry country: annual precipitation averages just 22.7 inches, and the county sees severe drought in about 34.7% of years, so a private well should be tested and sized for a dry year, not an average one⁷. The land is almost entirely open, with only about 2.3% wooded and 96.3% at 15% slope or less, so grading is rarely the obstacle, but heat is: the county is projected to see about 48.8 days a year at or above 100°F by mid-century⁷. Soils lean favorable for septic relative to many rural counties: about 36% of the land is rated free of severe limits for a conventional drain field⁷. Fisher County has no federal land, so public-land boundary issues are not a factor here⁷. It sits about 44 miles from the nearest metro area with a population density of about 4 people per square mile, a remote, sparsely populated county⁷. Typical homeowner's insurance runs high at about $2,650 a year, and the effective property tax rate is about 1.7%, for a median bill near $1,323 a year on the county's typical home⁷. Farmland trades at roughly $1,380 an acre against a typical home value around $101,592, both low figures for the region⁷.
