Kitchen and Bathroom Remodeling in Daly City: Permits, Inspections and Fog-Belt Ventilation

By ProRock Remodeling · CSLB #1154078 · Updated October 8, 2026

Do you need a permit to remodel a kitchen or bathroom in Daly City?

Yes. Under the California Building Code as adopted by Daly City, a permit is required to alter, convert, improve, remove or repair a building. The city's FAQ lists plumbing, mechanical and electrical work among the examples, and it adds a detail many homeowners miss: replacing or adding a sink, toilet or vanity requires a plumbing permit.

So a "simple" vanity swap is not as simple as it looks. If you're unsure, call the Building Division at (650) 991-8061.

How do you apply for a Daly City remodel permit, and when are plans required?

Daly City divides permits into quick permits and permits involving plans. Quick permits can be issued over the counter without a full plan review, and the city's list includes residential bathroom remodels, water heater and furnace replacement, and window replacement. You can apply online for quick permits or email the application and a credit card authorization to buildingdivision@dalycity.org.

Plans are needed for new construction and for changes to existing structures, such as rooms and stairways. Removing a wall to open up a Westlake kitchen falls into that category.

Permits are issued to the property owner or to a state-licensed contractor with a valid Daly City business license. The Building Division counter is on the second floor of City Hall, 333 90th Street, weekdays 8 a.m. to 5 p.m.

What inspections should you expect in Daly City?

Daly City's February 2025 inspection guidelines say work needing a permit can't start until the permit is issued, and each phase must pass before the next one begins. For a kitchen or bath, the key stops are usually:

1. Rough-in: drain, waste, vent and water lines, ductwork, and wiring and boxes, all before walls close.
2. Framing and insulation: where walls are opened or rebuilt.
3. Drywall: after it's hung and fastened, before taping.
4. Final: plumbing, mechanical and electrical, then the building final last.

Call at least two working days ahead with your permit number. Daly City inspectors are combination inspectors, so all trades can be inspected in one visit. Keep approved plans, the permit and earlier inspection reports on site. The inspector signs the job card at final, and that card becomes your record of completed work.

Why do Westlake homes remodel the way they do?

Daly City stayed small until the late 1940s, when Henry Doelger established Westlake, one of the earliest examples of a planned, large-tract suburb. Its rows of houses are said to have inspired Malvina Reynolds' 1962 song "Little Boxes." We'd say the boxes have aged with a lot of character.

Doelger's plans were built for efficiency, and that shapes remodels today:

• Living space upstairs, garage below. Many homes put the living space over a ground-floor garage or basement, so plumbing and wiring often run through the garage ceiling.
• Back-to-back plumbing. Bathrooms commonly share walls with kitchens to save on plumbing, which can make kitchen and bath work a natural pair.
• 8-foot ceilings. Plan cabinet heights and lighting around them.
• Ground-floor conversions. Many owners later turned the downstairs into rooms. The city's Residential Requirements Report (3R), required before most home sales, shows permits issued since January 1989, and rooms missing from it were likely built without permits.

Older systems behind the walls are also common. See our older-home hidden issues guide.

How do you prevent bathroom moisture problems in Daly City's fog belt?

Daly City's climate resembles San Francisco's Sunset and Richmond districts, with fog in spring and through summer. Cool walls plus hot showers equals condensation, so ventilation is a big part of a good bath remodel here.

• Choose a bath fan with a humidity control, so it runs when the room needs it, not just when someone remembers.
• Duct the fan outdoors, never into the attic or the garage ceiling below.
• Vent the kitchen range hood outdoors, too.
• Use moisture-resistant board and paint on bath walls and ceilings.

California's CALGreen code calls for humidity-controlled bath fans in new construction, and many building departments apply it to bathroom remodels too, so confirm with the Daly City Building Division. Our bathroom ventilation guide covers sizing. Karl the Fog is a fine neighbor. He just shouldn't move into your bathroom ceiling. For a nearby city we serve, see our South San Francisco guide.
