Webb County primarily exercises jurisdiction over unincorporated areas, while the City of Laredo manages its own extensive building and zoning permits. Development in unincorporated areas must comply with county subdivision regulations and floodplain management requirements. Specific environmental or fire safety reviews may be triggered by proximity to the Rio Grande or designated rural fire protection zones.
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.
