Guadalupe County only exercises permitting authority for septic systems and floodplain development in unincorporated areas, while incorporated cities like Schertz and Seguin manage all building, electrical, and plumbing permits within their city limits. Development in unincorporated areas must comply with county floodplain management regulations if located within a designated Special Flood Hazard Area.
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.
