Kitchen and Bathroom Remodeling in Foster City, CA: Permits, HOAs and Inspections

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

Foster City is not like its Peninsula neighbors. It was planned from scratch starting in 1958 on Brewer's Island, a former salt marsh built up with more than 14 million cubic yards of sand pumped from the Bay, and it was laid out around a central lagoon that doubles as its drainage basin. The result is a city of planned neighborhoods, many of them townhome and condo communities run by homeowners associations, with single-family streets backing onto the water. That mix shapes remodels here as much as the building code does. Here is how permits, HOAs and inspections fit together.

Do I need a permit to remodel a kitchen or bathroom in Foster City?

Yes. The city's Building Division states that a building permit is required for all interior and exterior changes, for both new work and replacements. Cosmetic work such as painting or new carpet does not need one. Kitchen and bathroom remodels appear by name in the city's over-the-counter permit guide, so plan on a permit for any remodel that touches plumbing, wiring, ventilation or walls.

Can I get a same-day kitchen or bath permit in Foster City?

Often, yes. Foster City's over-the-counter (OTC) permit guide lists kitchen and bathroom remodels without structural renovation as eligible for same-day permits. OTC review is by appointment only, Tuesdays and Thursdays from 9:00 to 11:30 a.m. For an OTC kitchen or bath permit you need:

• Dimensioned existing and proposed floor plans showing the full scope, including anything needed to meet current code.
• The completed application, submitted with the plans.
• An HOA approval letter, which may be required if your property is in an HOA.

Moving a bearing wall or opening the kitchen to the living room typically takes the project out of the OTC lane and into regular plan check. All building permit submittals can also be made electronically through eTRAKiT, or in person at City Hall, 610 Foster City Boulevard.

How do HOAs affect a Foster City remodel?

In Foster City, the HOA conversation usually comes first. The city's OTC guide tells applicants to check whether their property is in an HOA and notes an HOA approval letter may be required. If the project changes the outside of the home, such as a new kitchen window or a bigger slider to the deck, ask the Planning Division whether exterior review applies and whether it also wants your HOA's sign-off. Associations often have their own rules on things like work hours, parking and contractor access, so read your CC&Rs and ask your board. Our condo and HOA remodel guide walks through what to ask your board.

Does building on fill land matter for a remodel?

The city's own history notes that the original island was soft, silty mud, which is why the land was built up with sand rather than conventional landfill. For most interior kitchen and bath work, the ground under the house is not the headline. It matters most when you relocate plumbing. Moving a toilet, shower or sink drain can mean cutting into a concrete floor or rerouting under the house, and drain lines need proper slope. Have your contractor confirm what is under your floor before you commit to a new layout. Keeping fixtures roughly where they are is often the simplest path.

How do inspections work in Foster City?

Inspections are requested in eTRAKiT with at least 24 hours' notice. Foster City has one step some homeowners miss: every permit requires a pre-inspection after the permit is issued and before any construction or demolition begins. After that, the city's kitchen remodel handout lists rough framing, plumbing, mechanical and electrical inspections before walls are closed, then a final once work is done and smoke and carbon monoxide alarms are verified. On inspection day, check eTRAKiT after 8:30 a.m. to see your assigned window. Keep the permit card and approved plans on site.

When can work happen in Foster City?

The city allows construction equipment near residential areas from 7:30 a.m. to 8 p.m. on weekdays and 9 a.m. to 8 p.m. on weekends and holidays. Your HOA may be stricter, so check both. The ducks on the lagoon have not filed a noise complaint yet, but the neighbor sharing your townhome wall might.
