Email a Development Permit Application to the Austin County Planning and Development Department before anything is built or moved onto the property: planning1@austincounty.com for homes, other single-family development and septic permits, DebR@austincounty.com for commercial development. Attach a recorded copy of the deed and the 911 address letter from the Austin County Emergency Communication District. In a flood hazard area, an elevation certificate from a surveyor is required before the permit is issued. Commercial, multifamily and other non-single-family projects also need County Engineer approval through the Engineering Review Application. Septic systems need a separate On-Site Sewage Facility permit. A driveway culvert on a county road needs a Culvert/Driveway Permit signed by the precinct commissioner before it goes to Planning and Development. Permits must be posted where visible from the road. Call 979-865-5911 to pay.
