Brewster County (county seat: Alpine) covers 6,184 square miles with a population of 9,546 (2020). Official county website: www.brewstercounty.gov/. This page summarizes the verified building-regulation posture of unincorporated Brewster County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
No county building permit, code, or inspection exists — the county's official Permits & Procedures page lists only OSSF (septic), mass gathering, utility certificate, road-crossing/trenching, and GCD well-drilling permits, plus a 2021 outdoor-lighting order, a 1999 floodplain order, and subdivision regs; the state IRC-standards subchapter (LGC 233 subch. F) is opt-in per §233.152 and no Brewster adoption order was found, and even opted-in counties may not require prior approval or charge enforcement fees (§§233.153–.155).
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 Brewster County and how hard.
The score describes unincorporated county land only. Inside Brewster County, incorporated municipalities set their own, usually stricter, rules — including: Alpine. Land inside town limits follows town code.
Building rules are the first question people ask about Brewster 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.
