Unincorporated Waller County

Residential development in unincorporated Waller County requires a development permit, driveway permit, and septic/OSSF permit. Rental communities also need a certificate of compliance after approval of the infrastructure development plan. Fire-code overlay applies to commercial establishments, public buildings, and multifamily residential structures of four or more units.

Note: Waller County does not enforce building codes in unincorporated areas for general construction. However, septic/OSSF, driveway, development, and fire-code overlay requirements still apply to covered projects. Confirm specific project requirements directly with the County Engineer and Environmental Division.
