Do I Need a Permit to Remodel My Kitchen in California?

Most of the time, yes. A lot of people think permits are only for big jobs, like adding a whole new room. But a kitchen remodel usually needs one too. And the rules can be tighter than you'd expect.

So before you pick out cabinets, it's worth knowing what your city will ask for.

California Has One Rule Book

Every building in California follows the same set of rules. It's called the California Building Standards Code. Most people just call it Title 24. It covers the whole state, and it covers more than most people think. It includes the parts of your house that hold it up, plus the wiring, the pipes, the heating and cooling, and fire safety. But there's a catch that trips people up. The state writes the rules. Your city or county hands out the permit.

Cities and counties have to follow the state rules. They're also allowed to add their own rules on top, as long as those rules are stricter. So the big picture is the same everywhere in California. The small details change from town to town.

The State Rule Is Broad

The Contractors State License Board is the state agency that watches over contractors in California. On their permit page, they explain it simply. Under the state code, you can't build, add to, change, repair, move, improve, or tear down a building without first getting a permit from your building official. They also point out that rules are different in each city and county, so you should check with your local building department.

Read that list again. The word "change" is right there in it. That's a low bar, and it's why so many kitchen jobs end up needing paperwork. That same page has a list of every city and county building department in California, which is the fastest way to find yours.

Jobs That Usually Need a Permit

These four things most often mean you'll need one. This is based on how most California building departments handle kitchens, not one single state list, so check yours to be sure.

‍

1. Wiring work

Adding outlets, moving them, or putting in new circuits for a big appliance.

2. Pipework

Moving the sink or the dishwasher, or adding a second sink.

3. Gas work

Any new gas line, or moving the one you already have for a stove.

4. Work on structural walls

Taking a wall out, or cutting a new opening for a door or window.

‍

If your remodel touches any of these, plan on a permit.

Jobs That Often Don't

Some work is more about looks than safety. In a lot of cities, these are fine without a permit:

• Painting
• New floors
• New doors or handles on cabinets that stay where they are
• A new countertop, if nothing moves and the sink stays

One thing worth saying clearly, though. No permit doesn't mean no rules. The building code still applies. You just don't have to file for approval first.

One City, Up Close

City rules make a lot more sense when you can see a real one. This is how the City of Walnut Creek sorts kitchen jobs in its own handout for homeowners:

This reflects the city's published handout. Rules can change, so call the Building Division to confirm before you apply.

Look at the cabinet rows. Just swapping cabinets, with nothing else moving, still needs a full building permit there. The reason is the wiring. Once the cabinets come off the wall, the city wants the outlets behind them brought up to today's safety rules.

Now look at the countertop row. No permit, but only if the sink stays. Swap the sink at the same time and it moves up a level.

Your city will have its own version of this list, and it'll probably look similar. It may not match exactly. That's the whole reason to check.

The Rules Changed in January

If you're planning right now, this part matters. A new version of the state code took effect on January 1, 2026. It applies to any permit application sent in on or after that date. You can see the current code list on the California Building Standards Commission website.

One helpful thing to know: the code in place when your finished application goes in is the code your project follows all the way through. It doesn't change on you halfway.

There's more good news. The state has frozen new home building code changes through 2031, with a few exceptions for emergencies, fire safety, and saving energy. Before this, the rules changed every three years. So what you're dealing with now should stay put for a while.

What If Work Was Already Done Without One?

This comes up all the time, usually right when someone's about to sell.

Walnut Creek spells out its position in writing. When you apply to get old work approved, the city treats it like brand new work. It has to meet today's rules, not the rules from whenever it was actually built.

Sometimes that means opening walls back up so an inspector can look inside. They can't sign off on something they can't see.

The city also lists why it wants people to fix this instead of hiding it. Work done without a permit can cause trouble with your home insurance. It can make selling the house harder. And it can leave you personally responsible if something goes wrong later.

If that's your situation, sort it out before you list the house, not in the middle of a sale.
