Do you need a permit to remodel a bathroom in Los Angeles?

What needs a permit

• Moving or adding plumbing — relocating the sink, toilet, or shower drain
• Replacing a shower pan or waterproofing
• New or altered electrical circuits, adding an exhaust fan, moving outlets
• Removing, adding, or opening a wall
• Converting a tub into a walk-in shower (this almost always moves plumbing)
• Changing a window or its size
• Adding a bathroom where there wasn't one

What generally does not

• Swapping a toilet or faucet in the same location
• Replacing a vanity that connects to the same supply and drain
• New tile over an existing, sound substrate
• Paint, mirrors, towel bars, light fixture swaps on an existing box
• Re-glazing a tub

The grey zone is tile. New tile alone is cosmetic. But if you demo down to studs and discover rot, water damage, or a failed pan — and in mid-century Los Angeles houses you frequently do — you are now doing permitted work, whether that was the plan or not. Budget for it.

Which city are you actually in?

"Los Angeles" is not one jurisdiction. If your address is in the City of Los Angeles, you go through LADBS. Burbank, Glendale, Pasadena, Santa Monica, and Beverly Hills each run their own building departments, with their own fees, timelines, and quirks. Unincorporated areas go through LA County Public Works.

This matters more than people expect. The same bathroom can clear plan check in a week in one city and take a month next door.

What a permit actually costs

For a typical bathroom remodel, permit and plan check fees generally run a few hundred to a couple of thousand dollars, depending on the city and the declared value of the work. Compared to the cost of the remodel, it is noise. Compared to the cost of not having it, it is nothing.

The honest reason people skip it

Permits mean inspections, and inspections mean the schedule is not entirely in the contractor's control. That is inconvenient. It is also the entire point — an inspector is the only person on your project who is not being paid by the person doing the work.

We pull the permits and manage the inspections as part of the job. It is in the bid, not bolted on afterward.

Questions

What happens if I remodel a bathroom without a permit?

Three things, eventually. The work fails to appear in city records, so it becomes a disclosure problem at resale and can knock down an appraisal. If the city finds out, you pay a permit-in-arrears penalty and may have to open finished walls for inspection. And an insurance claim from an unpermitted shower pan leak can be denied. The permit is not the expensive part. The retroactive fix is.

How long does a bathroom permit take in Los Angeles?

For a straightforward bathroom remodel with no structural changes, an over-the-counter or express plan check typically takes days to about two weeks in the City of Los Angeles; smaller cities like Burbank and Glendale are often faster. Add structural changes and you are into a full plan check — four to eight weeks.

Who pulls the permit, me or the contractor?

Your licensed contractor should pull it, and that matters. When a homeowner pulls their own permit as an "owner-builder," the homeowner takes on the liability for the work and for anyone injured on site. If a contractor asks you to pull the permit yourself, treat that as a red flag.
