“Second-story additions in the Valley are the most permit-intensive project we do. LADBS requires structural plans stamped by a licensed engineer, a Title 24 energy report, and — in fire zones — a fire sprinkler evaluation. From design start to permit in hand: 5–7 months. Budget that lead time into your project timeline.”
Confirm your lot's existing FAR (Floor-Area Ratio) and remaining development potential before designing any room addition. LADBS has maximum FAR limits for single-family zones; exceeding FAR triggers a variance application that adds 3–6 months and significant cost. Calculate your remaining envelope before committing to an addition size.
