Permitting overview

ADUs are reviewed as residential accessory structures or separate dwelling units depending on size and utilities. Expect requirements for site plans, setbacks, building-code compliance (IRC/Texas amendments), and utility connections. Contact the Planning or Development Services office early to confirm zoning and lot-specific constraints. See the municipal code for zoning definitions and accessory use rules.
