Moore County (county seat: Dumas) covers 900 square miles with a population of 21904. Official county website: www.co.moore.tx.us/. This page summarizes the verified building-regulation posture of unincorporated Moore County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
No county zoning or building code on unincorporated land under LGC ch.233; only OSSF septic permitting applies.
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 Moore County and how hard.
The score describes unincorporated county land only. Inside Moore County, incorporated municipalities set their own, usually stricter, rules — including: Dumas, Cactus, Sunray and the Moore County portion of Fritch enforce their own municipal codes, permits and zoning.. Land inside town limits follows town code.
Building rules are the first question people ask about Moore 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.
