City permits are required to construct and operate a new onsite wastewater treatment system (OWTS). For all existing OWTS, operating permits must be obtained when a property is sold. For commercial and multifamily OWTS, renewable operating permits are required.
Applications for new OWTS are reviewed by Environmental Health, Planning, Geology, Biology, and in certain cases Coastal Engineering and Public Works. Many commercial and multifamily OWTS applications must also be concurrently processed by the Los Angeles Regional Water Quality Control Board.
