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.
Planning Permits: Step 1 - Coastal Development Permit
After obtaining an approved CDP from the Planning Department, final approval of the OWTS design must first be obtained from Environmental Health staff (Building Plan Check stage). Conformance with project CDP project conditions must be demonstrated prior to final approval. Apply for a Coastal Development Permit (CDP) with the Planning Department. If you have questions, contact Planning Department staff.
Construction Permits: Step 2 - Combination Sewer/Septic Permit
Apply for a Combination Sewer/Septic Permit with Building Safety staff prior to installation. If you have questions, contact Building Safety staff.
