Fisher County, TX Building Permits, Zoning & Septic Rules

Fisher County, Texas has no building or permit department listed on its official site, and Texas counties generally cannot require residential building permits outside cities, so unincorporated Fisher County most likely does not require one¹. No zoning department or ordinance was found either, so minimum lot size, setbacks and RV, tiny-home or manufactured-home occupancy are unregulated by the county based on current findings²³. Both answers rest on the absence of a published county rule, not a confirmed ordinance search of every county record, so call the County Judge's office to check before you build⁴. Septic systems need a state OSSF permit, most likely through the TCEQ regional office since no local authorized agent was found⁵⁶.

Do you need a building permit 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 found during this research⁹. 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 regardless¹⁰⁹. 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 instead⁴.

Who is the Fisher County building department, and how do you reach them?

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 records⁴¹¹. 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 [email protected]⁴. 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 325-776-2401¹¹. Property tax questions go to the Tax Assessor-Collector at PO Box 278, 100 N. Concho, Roby, TX 79543, phone 325-776-2181¹².

Does Fisher County have zoning?

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 zoning². 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 based on current findings³. 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 changed⁴. Subdivision plats and any recorded deed restriction, which a lack of zoning does not override, are filed with the County Clerk¹¹.

How do septic permits work in Fisher County?

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 from⁶⁵. 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 during this research, so a buyer should call TCEQ directly to confirm before assuming no local agent exists⁵. 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 line⁶. 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 of the counties in this guide series, though a site evaluation still confirms the specific parcel¹³.

Can you live in an RV or tiny home on your land in Fisher County?

Based on current findings, living in an RV or tiny home on unincorporated land in Fisher County is unrestricted by county zoning, since no zoning ordinance was located³. 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 it⁴. 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 agent⁶⁵.

Building a home in Fisher County: the steps, in order

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 online⁴.
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 on¹¹.
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 begins⁶⁵.
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 counties in this guide series¹³.
If the driveway connects to a state highway, get a TxDOT Form 1058 permit before construction begins⁸.
Confirm your property tax account with the Tax Assessor-Collector at 325-776-2181 before closing¹².
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.

What to check before you buy land in Fisher County

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 one¹⁴¹⁵. 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-century¹⁶¹⁷¹⁸. 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 field¹³. Fisher County has no federal land, so public-land boundary issues are not a factor here¹⁹. It sits about 44 miles from the nearest metro area with a population density of about 4 people per square mile, among the most remote and sparsely populated counties in this guide series²⁰²¹. 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 home²²²³²⁴. Farmland trades at roughly $1,380 an acre against a typical home value around $101,592, among the lowest of either figure in this guide series²⁵²⁶.

Watch-outs

Fisher County's official site lists no building, zoning or floodplain department, and whether the county ever adopted the optional state resolution for residential building-code enforcement is unconfirmed, so call the County Judge's office at 325-776-2151 before you build rather than treat this guide's answer as a re-verified legal ruling⁴¹.
No confirmed local TCEQ authorized agent was found for Fisher County septic permits, so call TCEQ directly to confirm the regional office is still the permitting authority before you apply⁵.
This guide's zoning and building-permit answers rest on the absence of a published county rule, not a courthouse-by-courthouse ordinance search, so a buyer with an unusual plan should still confirm with the County Judge's office³.
The County Clerk's office cannot receive US Mail at its street address; use PO Box 368, Roby, TX 79543 for anything mailed¹¹.

Living off-grid in Fisher County, Texas

Is Fisher County a good place to live off-grid or homestead?

Do you need a building permit in Fisher County, Texas?

Can you live in an RV or tiny home on your land in Fisher County?

Living in an RV on your own land in Fisher County is allowed: Unincorporated Fisher County: no county rule sets this, because Texas law gives zoning power only to certain counties, and Fisher County has no zoning ordinance. The county legal census found no county zoning ordinance, citing fishercounty.org. Septic, floodplain, subdivision and health rules still apply; cities and towns set their own rules inside their limits.
