Tyler County (county seat: Woodville) covers 924 square miles with a population of 19,798 (2020). Official county website: www.co.tyler.tx.us/. This page summarizes the verified building-regulation posture of unincorporated Tyler County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
No Texas county residential building code by default; no evidence Tyler opted into LGC 233 Subchapter F, and that subchapter forbids prior approval, zoning, and enforcement fees even where adopted. IRC/IECC nominally applicable (H&S 388) but no county enforcement. Score 9 = TX no-enforcement ceiling.
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 Tyler County and how hard.
The score describes unincorporated county land only. Inside Tyler County, incorporated municipalities set their own, usually stricter, rules — including: Woodville, Colmesneil, Chester, Ivanhoe. Land inside town limits follows town code.
Building rules are the first question people ask about Tyler 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.
