Planning

Do I need a permit for my renovation?

The short version: if you’re changing the structure, plumbing, or electrical, almost certainly yes. If you’re changing finishes only, often no. Here’s the real breakdown.

Usually needs a permit

• Moving or adding plumbing. New sink, shower, or toilet locations, or rerouting water or gas lines.
• Electrical work beyond a straight swap. New circuits, a panel upgrade, or added outlets and fixtures.
• Removing or moving walls. Especially anything load-bearing — this also requires engineering, not just a permit.
• Any addition or ADU. New square footage always requires permits, plus zoning review.
• Structural or foundation work. Anything touching the home’s structure, by definition.

Often doesn’t need a permit

• Painting, flooring, and finishes. Cosmetic work that doesn’t touch structure or systems.
• Cabinet or countertop replacement in the same footprint. Swapping what’s there for something new, without moving plumbing.
• Fixture swaps. A new faucet, toilet, or light fixture in the exact same spot as the old one.

This is a general guide, not a ruling on your specific project — confirm with your contractor or LADBS directly, since the line between “cosmetic” and “needs a permit” isn’t always obvious until someone who knows the code looks at your actual scope.

Why it matters even when it’s tempting to skip

Unpermitted work doesn’t just carry a risk of fines. It can complicate or delay a home sale, cause real problems with an insurance claim if something goes wrong later, and in some cases has to be torn out and redone to code before a sale can close. A contractor who suggests skipping a needed permit to save time or money is shifting that risk onto you, not absorbing it themselves.

The good news: it’s often faster than you’d expect

LA has an express-permit program for many straightforward residential projects that can clear in a day to a few days without full plan check. It’s only for projects within a limited scope, so it won’t cover everything — but it means “needs a permit” doesn’t automatically mean a long wait. See our renovation timeline guide for realistic ranges by project type.

General guidance based on common LADBS categories as of 2026; not official guidance, and every project’s specifics can change what’s actually required. Confirm with LADBS (ladbs.org) or your contractor before assuming either way.
