Kitchen and bathroom remodeling in Redwood City, CA: permits, inspections and what to expect
Do you need a permit to remodel a kitchen or bathroom in Redwood City?
In most cases, yes. Redwood City's Building Division states that a building permit is required for all work not specifically exempted by Section 105.2 of the California Building Code. That exemption list covers minor finish work such as painting and flooring, but a typical kitchen or bathroom remodel moves plumbing, adds circuits, replaces a shower or shifts a wall, and that work needs a permit. If your scope is truly cosmetic, ask the city to confirm before you skip the paperwork.
The city's residential checklist also spells out shower rules: the shower must be at least 1,024 square inches and fit a 30-inch circle, and shower doors must open outward with at least a 22-inch clear opening. Those numbers matter when you are squeezing a walk-in shower into a compact hall bath in an older Farm Hill or Mount Carmel home.
How do you apply for a remodel permit in Redwood City?
Redwood City offers complete permitting services online. Applications and drawings are uploaded through the city's eTRAKiT portal, with each file named by the project address. For an alteration, the residential checklist calls for:
- A signed permit application form
- Three sets of drawings on sheets at least 22" x 17", including fully dimensioned existing and proposed floor plans
- Title 24 energy forms for conditioned space, plus job specifications
- Structural calculations or a soils report, if the scope calls for them
Plan review starts once the application is in and the plan review fees are paid. The city notes that review times currently range from 6 to 24 weeks depending on scope, so a simple bath refresh and a gut-and-reconfigure kitchen in Emerald Hills can land at very different ends of that range. Not sure which permits apply? The city suggests starting with a permit technician at (650) 780-7350 or at the City Hall counter.
Can you get a faster review?
Possibly. Redwood City's One Stop service lets you meet with building staff, who may approve a project while you wait or return comments. Residential interior alterations and remodels are listed as eligible, while ADUs and some additions combined with interior remodels are excluded. You can check in at City Hall Monday through Thursday, 1:00 to 3:00 p.m., or, after receiving a permit number online, email the permits desk to request a virtual One Stop review. Bring PDF plans, the completed application and the checklist documents.
What happens during a Redwood City remodel inspection?
Once work begins, inspections are tied to the permit and its job card. On a contractor-run job, the city requires a qualified employee on site at each inspection with the approved plans, permit and job card. On an owner-builder job, the property owner stands the inspection. Typical remodel milestones look something like this:
| Stage | What is usually checked |
|---|---|
| Rough-in | New plumbing, electrical, venting and framing before walls close |
| Shower pan / waterproofing | Pan and waterproofing before tile goes on |
| Insulation / drywall | Insulation and wallboard where walls were opened |
| Final | Fixtures, outlets, ventilation and overall code compliance |
The exact sequence depends on your scope, so confirm it with the Building Division for your permit.
How long is a Redwood City permit valid?
A permit is valid for 365 days from issuance, and every passed field inspection extends it for another 365 days. Steady progress keeps a permit alive, while a project that stalls for a year can lapse. Also worth knowing: the city notes that a building permit belongs to the property owner, not the contractor.
What should Redwood City homeowners plan for before remodeling?
Redwood City's "Climate Best by Government Test" slogan is good news for scheduling, since mild weather rarely gets in the way of interior work. The housing stock is the bigger variable. Older homes can hide outdated wiring or tired plumbing behind the walls, hillside homes in Emerald Hills may have tricky access for deliveries, and townhomes and condos in Redwood Shores may add HOA approvals on top of the city permit. Depending on scope, the city also notes that fire sprinklers may be required for additions and remodels, which is worth asking about early if you are expanding.
