Galveston County primarily exercises jurisdiction over unincorporated areas, while incorporated cities manage their own building permits and zoning. The county enforces specific regulations for coastal construction due to its location along the Gulf of Mexico, including strict adherence to windstorm certification requirements and floodplain management ordinances.
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.
