Permits in Ector County are highly decentralized; the City of Odessa handles its own building and zoning permits within city limits. The Ector County Development Office oversees development, septic, and floodplain permits for unincorporated areas. Floodplain development permits are required for any construction within designated FEMA flood 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.
