AVOID THESE PITFALLS
Learn from the most common mistakes that cause delays and rejections — so yours doesn't end up on this list.
Unpermitted work in LA can result in stop-work orders, fines up to $5,000/day, and mandatory removal of completed work.
LA has complex zoning overlays (hillside, coastal, historic). What is allowed in one neighborhood may be prohibited in another.
California requires a Title 24 energy report for most new construction and additions. Forgetting this delays plan check approval.
Missing required inspections (especially framing before drywall) means work must be opened up for inspection later — costly and disruptive.
Unlicensed contractors void insurance coverage and expose owners to liability. LADBS may refuse to issue permits.
