Los Angeles Solar Engineering Questions
How long does LADBS solar plan check approval take?
LADBS offers over-the-counter solar permitting for standard residential systems. Our 48-hour plan sets are formatted specifically to pass LADBS plan check on first submission without corrections.
Do I need an MPU (Main Panel Upgrade) plan set for LA solar installations?
If your existing electrical panel is rated at 100A or 125A and cannot support the 120% busbar rule for solar backfeed, we include full MPU panel upgrade single-line diagrams in your permit package.
