ARTICLE I · COUNTY BASELINE
CODES & LOCAL AUTHORITY
FIPS 48491
Article I · County Baseline

The county inherits from the state. And adds local rules.

2021 International Codes commonly adopted with city amendments.

City departments own most permit work. Williamson County handles unincorporated permits and on-site sewage facility (OSSF) review.

Edwards Aquifer Recharge Zone overlays add TCEQ review for ground-disturbing work in western parts.

How this fits with the state

The state authority here is Texas Department of Licensing and Regulation; Texas State Board of Plumbing Examiners. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
