Overview of the Permit Process

Typical steps for a rooftop PV permit in Los Angeles include plan preparation, plan check submission to LADBS, permit issuance, installation, inspections, and final approval or certificate of occupancy for affected structures. Many installations also require electrical permits and a utility interconnection application. For official LADBS guidance on solar permit requirements and checklists see LADBS solar permits guidance[1].
