What Requires a Solar / Photovoltaic Permit in Los Angeles
Every solar panel installation in Los Angeles requires a permit from LADBS, regardless of system size or property type. Residential and commercial properties must submit detailed plans demonstrating electrical capacity, structural integrity, and compliance with California Title 24 energy standards. The permit process applies to new installations, system upgrades, and modifications to existing solar infrastructure. LADBS specifically requires documentation showing how the proposed solar system connects to the building's electrical grid and meets current seismic and wind load requirements.
What Doesn't Require a Permit
Small temporary solar devices under 100 watts do not require a permit in Los Angeles. Portable solar charging stations used for recreational vehicles or temporary outdoor events may also be exempt from LADBS review. However, any permanent solar installation connected to building electrical systems must undergo comprehensive permit review, regardless of size or perceived simplicity.
