Midland County has limited jurisdiction over building permits, as most construction occurs within the incorporated City of Midland or its extraterritorial jurisdiction. The county primarily manages rural development, septic systems, and floodplain management, while incorporated cities maintain their own building departments and zoning authority.
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.
