Permits are primarily handled by individual municipalities for incorporated areas, while the county manages development in unincorporated regions. The county enforces specific regulations related to coastal flood zones and windstorm requirements due to its location on the Gulf Coast.

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.
