When a Deck Needs a Permit in Los Angeles

Whether a deck needs a building permit in Los Angeles usually comes down to how high and how big it is. Low, ground-level platforms are often exempt, while raised decks need a permit — many cities draw the line at decks more than about 30 inches above grade (where guardrails and footings come into play), but Los Angeles’s exact threshold is set by the LADBS. Attached decks almost always require a permit because they tie into the house’s structure, and even a freestanding deck usually needs one once it passes the size or height cutoff. Check the requirements above before you build, and note that zoning setbacks from property lines apply regardless.

Do You Need a Permit to Repair or Replace a Deck in Los Angeles

It depends on how much you’re changing. Swapping worn decking boards or railing on the same layout is usually treated as maintenance and often doesn’t require a permit in Los Angeles. But replacing the structural framing (joists, beams, posts, or footings), rebuilding the deck, enlarging it, or changing its height generally does — at that point it’s regulated like new construction. When in doubt, describe the scope to the LADBS before starting; the requirements above outline what Los Angeles expects.
