Fisher County (county seat: Roby) covers 902 square miles with a population of 3,672 (2020). Official county website: www.fishercounty.org/. This page summarizes the verified building-regulation posture of unincorporated Fisher County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
No county residential building code or building department found. Texas gives counties no general code authority; the only path (Local Gov't Code ch. 233 Subchapter F) is opt-in and Fisher shows no adopting resolution. Even if it opted in there is no county permit, no prior approval, no zoning, and no county fee (§233.153(d),(f)). The state IRC/IECC nominally 'applies' but there is no county enforcement mechanism in unincorporated land — practical building freedom is near-maximal (9, not 10, because OSSF/septic still applies). The incorporated towns (Roby, Rotan, and the Fisher-County portion of Hamlin) can regulate inside their own limits; scored land is OUTSIDE them.
The claim above is source-verified (official statute/county documents; URL, direct quote, and date on the full card). Method: how we verify.
No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Fisher County and how hard.
The score describes unincorporated county land only. Inside Fisher County, incorporated municipalities set their own, usually stricter, rules — including: Roby, Rotan, Hamlin (partial). Land inside town limits follows town code.
Building rules are the first question people ask about Fisher County — and the easiest one to answer. They're rarely the one that decides it. The full card grades all ten dimensions, every claim quoted from the county's own code.
