Atascosa County (county seat: Jourdanton) covers 1232 square miles with a population of 48981. Official county website: co.atascosa.tx.us/. This page summarizes the verified building-regulation posture of unincorporated Atascosa County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
County permitting covers OSSF septic, floodplain, subdivision, driveways, utilities, and commercial fire inspection (NFPA 1), but single-family homes on unincorporated land are not subject to a residential building code.
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 Atascosa County and how hard.
The score describes unincorporated county land only. Inside Atascosa County, incorporated municipalities set their own, usually stricter, rules — including: City of Pleasanton enforces its own building codes, City of Jourdanton enforces its own codes, City of Poteet enforces its own codes. Land inside town limits follows town code.
Building rules are the first question people ask about Atascosa 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.
