The Short Answer
A full kitchen remodel in San Bruno requires a building permit if you're moving walls, relocating plumbing, adding electrical circuits, modifying gas lines, installing ducted range hoods, or changing window/door openings. Cosmetic-only work (cabinets, countertops, flooring, paint, appliance swap on existing circuits) is exempt.
San Bruno sits in unincorporated San Mateo County fire-jurisdiction territory but enforces its own building code. The city adopts the California Building Code (2022 edition as of this writing) with local amendments. A critical San Bruno quirk: the city requires all kitchen remodels involving ANY structural or MEP change to pull THREE separate permits — one master building permit, plus standalone plumbing and electrical permits — all filed together at City Hall (no online portal; in-person or mail submission). This is stricter than some Bay Area neighbors that bundle MEP into one building permit. San Bruno also enforces a mandatory GFCI requirement on every counter receptacle within 6 feet of a sink (stricter than the IRC 48-inch rule), and all range-hood ducts terminating through exterior walls require a detailed shop drawing showing the duct cap, flashing, and sealant. Load-bearing wall removal requires a structural engineer's stamp — no exceptions. The city's plan-review timeline runs 4–6 weeks, and you'll face three separate inspections (rough plumbing, rough electrical, framing/drywall, final), meaning the project stays on-hold between inspections. Pre-1978 homes trigger federal lead-paint disclosure, which adds paperwork but not hard cost.

What happens if you skip the permit (and you needed one)

San Bruno full kitchen remodel permits — the key details

San Bruno Building Department requires a permit whenever a kitchen remodel involves structural changes, electrical additions, plumbing relocation, gas-line modification, or ventilation ducting through exterior walls. The threshold is low: moving a single wall, adding one new circuit, or relocating even one sink requires full permitting. The city enforces California Title 24 (energy code) and California Plumbing Code (Title 24, Part 5) in addition to the 2022 CBC. Unlike some counties that allow a single-permit application to cover building, plumbing, and electrical, San Bruno requires three separate permit applications filed concurrently — a building permit (forms B-1 and B-2), a plumbing permit (form P-1), and an electrical permit (form E-1). All three must be submitted together; the city will not issue any until all three are deemed complete. Fees are calculated separately: building permit is typically 1.5% of project valuation (floor $150 minimum), plumbing is a flat fee plus per-fixture charges ($250 base + $50 per new fixture), and electrical is flat-fee ($300–$500 depending on circuit count). If your kitchen project budget is $40,000, expect $600–$1,200 in permit fees alone, not counting plan-preparation costs.

Load-bearing wall removal is a frequent flashpoint in San Bruno kitchens because many homes in the area were built in the 1950s–1970s with simple 2x4 framing; opening a wall between kitchen and living room often requires a beam. San Bruno requires a structural engineer's letter (or full design) for ANY load-bearing wall modification — no exceptions, no 'we'll just sister joists and hope.' Engineer fees run $500–$1,500 for a simple beam calc. The engineer must certify the beam size, material (steel or engineered lumber), bearing points, and connection details per California Building Code Section 2201 (structural design). The city's building inspector will not issue a framing inspection approval without the engineer's stamp. If you're simply removing a non-bearing partition wall (a wall that runs perpendicular to joists, sits on a floor joist rather than a beam, and carries no load from above), you still need a building permit, but no engineer letter — the permit application includes a checklist to verify load-bearing status. Get a framing contractor or engineer to confirm this in writing before filing.

Electrical work in kitchens is heavily regulated by NEC Article 210 (branch circuits and outlets) and California Title 24. San Bruno enforces a requirement that every kitchen counter receptacle must be on a 20-amp small-appliance branch circuit — meaning you cannot have a general-purpose outlet on a 15-amp circuit in the kitchen. You must have a minimum of two 20-amp dedicated circuits serving counter outlets (not including the refrigerator circuit, which is separate). Every receptacle within 6 feet of the kitchen sink must be GFCI-protected; San Bruno interprets this as every counter outlet within 6 feet of the sink edge, which is stricter than the 48-inch radius in the IRC. The city's electrical inspector will reject a rough plan if the circuit schedule doesn't clearly show two 20-amp small-appliance circuits, and if GFCI protection isn't applied to every affected outlet. When you submit your electrical permit, include a single-line diagram showing the existing panel, new circuits, breaker sizes, and all GFCI outlets labeled. Many applicants fail to show the existing panel — if you don't, the plan reviewer will request it. Lead time: order the single-line diagram from your electrician 2–3 weeks before you file; the city's plan-review team uses it to coordinate with the plumbing rough-in.

Plumbing relocation in kitchens requires detailed trap-arm and venting drawings that comply with California Plumbing Code Section 408 (trap requirements) and Section 504 (vent piping). If you're moving the sink to a new location, the drain must run with the correct slope (1/4 inch per foot minimum, 1/2 inch per foot maximum per code), must connect to an existing drain stack within 5 feet of the trap outlet (or require a new vent stack), and must not exceed the developed length limits for the trap arm (typically 3.5 feet for a 1.5-inch line). San Bruno's plumbing inspector will physically inspect the rough-in before drywall — they check slope with a level, measure trap-arm length, verify vent connections, and confirm that no 'S' traps exist (prohibited). If you're relocating a dishwasher, you need a separate drain line; it cannot share the sink trap. Hot-water line relocation must include insulation if the pipe runs more than 10 feet from the water heater (Title 24 requirement). Many first-time remodelers underestimate the cost of rerouting plumbing; if your sink is moving more than 10 feet, budget an extra $2,000–$4,000 for new drain and supply lines, new stack connection, and possible new vent drilling. The plumbing permit application requires a floor plan showing all new fixture locations, drain routing, vent connections, and hot-water supply path.

Range-hood exterior ducting is another common requirement in San Bruno kitchens. If you're installing a new range hood with ducting through an exterior wall, the city requires a shop drawing showing the duct diameter, material (smooth rigid duct preferred; flex duct discouraged), exterior termination cap (with damper), flashing detail, and sealant specification. You must drill through the rim joist, band board, or exterior sheathing; the city's inspector will verify that the duct is sloped (1/8 inch per foot minimum pitch toward the exterior), has no horizontal runs longer than 8 feet without makeup air, and terminates at least 10 feet from windows and doors. Many kitchens lack sufficient head space for a sloped duct; if yours does, you may need a booster fan downstream (extra cost, extra electrical circuit). Gas-line modifications follow similar scrutiny: if you're relocating the range or adding a gas connection, a licensed plumber must file the gas permit, test the line at 10 psig, and obtain a pressure-test certificate. The inspector will verify the line is 3/8-inch soft copper or rigid black iron (per California Plumbing Code Section 416), has a shutoff valve within 3 feet of the appliance, and is bonded to ground if it's 10 feet or longer. On a side note: some kitchens have old gas lines running through walls; if your remodel disturbs these, the plumber must cap and abandon them per code — cost is minimal (few hundred dollars) but easy to overlook.

Three San Bruno kitchen remodel (full) scenarios

Scenario A
Cosmetic cabinet and countertop swap, same-location appliances, paint, flooring — Millbrae Ranch, built 1968
You're replacing cabinets, counters, and flooring, repainting, and swapping a gas range with an identical new model in the same footprint. No walls are moved, no plumbing is relocated, no new electrical circuits are added (the range outlet is reused), and no gas line is modified (the line and shutoff stay in place). This work is cosmetic and exempt from permitting under California Building Code Section 100.5 (minor alterations). San Bruno's building department would classify this as 'like-for-like replacement' and would not require a building, plumbing, or electrical permit. However, you MUST obtain a lead-based paint disclosure if the home was built before 1978 (this home was 1968, so yes) — the seller or contractor must provide the federal EPA disclosure form, and you must sign it before work begins. The disclosure is required by federal law; failure to provide it is a federal violation (not enforced by San Bruno, but could become a liability if you ever sell). Cost: $0 permit fees. Flooring and cabinet work can proceed without inspections. If the new range requires 240V service and your existing outlet is only 120V, that would trigger an electrical permit — but if you're truly keeping the same appliance type and location, this shouldn't apply. Timeline: no waiting for plan review; you can start immediately after disclosure is signed.
No permit required | Lead-paint disclosure mandatory (pre-1978 home) | Same-location appliance replacement exempt | Cabinet and flooring work exempt | $0 permit fees | Start immediately
Scenario B
Kitchen island added, new sink, dishwasher relocated, existing gas range moved 6 feet, new range hood with duct through exterior wall — San Bruno Highlands, built 1985
You're adding a 4-foot island with a secondary sink and dishwasher, moving the existing gas range 6 feet to a new location, installing a new range hood with ducting through the north exterior wall, and reconfiguring counters. This triggers four separate permit requirements. First, the new island sink requires new plumbing (drain, supply, vent) — San Bruno requires a plumbing permit with floor plan showing the new trap-arm routing, vent connection, and hot-water line (insulated, per Title 24). The dishwasher relocation also requires a new drain line and 120V dedicated circuit. Second, moving the gas range 6 feet triggers a gas-line modification permit: the old shutoff and line must be capped per code, and a new line must run from the existing meter/shutoff to the new location (estimate $800–$1,500 for the gas line work, plus gas-permit fee $150–$250). Third, the new range hood requires a building permit detail showing the exterior duct penetration, cap, and flashing; San Bruno's building inspector will verify that the duct is sloped away from the home and has a dampered cap. Fourth, the dishwasher and island sink each require new electrical circuits: the dishwasher needs a dedicated 120V, 20A circuit, and the island sink needs GFCI protection on any outlets within 6 feet. The island itself may require a permit if it's fixed (bolted to the floor); if it's movable, it's treated as an appliance and doesn't require framing approval, but the plumbing and electrical still do. San Bruno's electrical inspector will examine the single-line diagram showing the two new 20A circuits, verify GFCI on island outlets, and inspect rough-in before drywall. The building permit application includes three forms (B-1, B-2) plus a floor plan showing island location, sink/range placement, and range-hood duct routing. Costs: building permit $400–$600, plumbing permit $300–$450 (base + per-fixture), electrical permit $350–$500, gas-permit fee $150–$250. Contractor labor: plumbing $2,000–$3,500, electrical $1,200–$2,000, gas-line work $800–$1,500. Inspections: rough plumbing (1 week after drywall is framed), rough electrical (concurrent with framing), framing inspection (after rough-ins are complete), drywall inspection (after drywall hung, before finish), final inspection (after all work is complete). Total timeline: 6–10 weeks from permit issuance to final approval. The project stalls between inspections if any rough-in fails.
Permit required — building + plumbing + electrical | Island sink requires new trap-arm and vent | Gas line relocation $800–$1,500 | Range-hood duct cap detail required | Dishwasher needs dedicated 120V circuit | Island outlets require GFCI | Permits total $1,200–$1,800 | Timeline 6–10 weeks | Three separate inspections (rough plumbing, rough electrical, final)
Scenario C
Load-bearing wall between kitchen and dining room removed, beam installed, kitchen expanded into former dining space, new electrical panel sub-feed added — San Bruno built 1956
You're removing a load-bearing wall that runs east-west between the kitchen and dining room, installing a steel beam or engineered-lumber header to span the opening (approximately 16 feet), and expanding the kitchen into the former dining space. This is a structural modification that triggers a building permit, engineering requirement, and electrical permit (sub-feed to handle new circuits in the expanded space). San Bruno Building Department requires a structural engineer's design for the beam: the engineer must calculate the load from the wall above (including second-floor framing if present), the roof load, and other dead load; size the beam accordingly (typically a 12-inch steel I-beam or 2x16 engineered lumber); and design the bearing points (posts on new footings or rim-joist attachment). The engineer provides a one-sheet design drawing showing beam size, material, bolting, bearing details, and a note: 'Designed per 2022 CBC Section 2304 (wood) or Section 2206 (steel).' San Bruno's building inspector will not issue a framing inspection approval without this stamp. Cost: engineer design $800–$1,500. Beam material and installation: $2,500–$4,500 for steel; $1,500–$2,500 for engineered lumber. Building permit: $500–$800 (based on 1.5% of structural modification valuation, or flat fee if city uses one). Electrical permit: $350–$500 (new sub-feed to expanded space requires new circuits). The city will also require a framing inspection after the wall is removed and the beam is in place, before any drywall is hung. If the wall contains plumbing or gas lines, these must be rerouted before removal (additional $800–$1,500 for plumbing relocation). If the wall is exterior (unlikely in this scenario but possible), it would also trigger a thermal envelope inspection to ensure insulation is maintained. Lead-paint disclosure is required (pre-1978 home, definitely painted). Timeline: engineer design 1–2 weeks, permit approval 3–4 weeks, construction 2–3 weeks, framing inspection 1 week, total 7–10 weeks. The project cannot proceed past the framing stage without the structural engineer's sign-off. Many first-time remodelers underestimate the structural engineering cost and timeline; budget 3–4 weeks just for the engineer to issue a stamp.
Permit required — structural engineering mandatory | Engineer design $800–$1,500 | Beam installation $1,500–$4,500 | Building permit $500–$800 | Electrical permit $350–$500 | Framing inspection required (no drywall until passed) | Lead-paint disclosure required | Timeline 7–10 weeks | Structural engineer's stamp non-negotiable

San Bruno's three-permit filing requirement and why it delays kitchens

San Bruno City Hall requires three separate, simultaneous permit applications for any kitchen remodel involving plumbing, electrical, or structural work. The building permit (forms B-1, B-2, scope statement), the plumbing permit (form P-1, fixture list, riser diagram), and the electrical permit (form E-1, single-line diagram, outlet schedule) must all be submitted together in one packet. The city will not begin plan review on any of the three until all three applications are deemed 'complete' — meaning if your electrical diagram is missing a single outlet label, the entire submission is rejected and sent back, and plumbing review stalls too. This differs from neighboring jurisdictions (e.g., Daly City, South San Francisco) that bundle MEP permits into a single building-permit application. San Bruno's approach is more rigid and slower: expect 4–6 weeks for plan approval, versus 2–3 weeks in faster cities. The upside is that the three departments (building, plumbing, electrical) coordinate internally before returning comments, so you get one round of revisions instead of three. But if you submit incomplete paperwork, you lose 1–2 weeks just getting a rejection letter. Best practice: hire a permit expediter or architect to prepare all three applications and coordinate submission. Cost for expediting: $500–$1,000, but often saves 2–3 weeks and prevents rejection cycles.

Once plan approval is issued, San Bruno schedules inspections in a specific sequence: rough plumbing (after plumbing is stubbed in, before drywall), rough electrical (concurrent with framing, before drywall), framing inspection (after any structural work and rough-ins are complete), drywall inspection (after drywall is hung, before finish), and final inspection (after all work is complete). Each inspection must be requested via the city's online portal or by phone; the city's inspector schedules appointments 2–3 business days out. If an inspection fails, the project stalls until corrections are made and a re-inspection is scheduled (another 2–3 days). A failed rough-electrical inspection for missing GFCI labeling on the plan can delay the project by a week. San Bruno's inspection team is professional and fair, but they enforce code strictly; bring your contractor's license number, permit number, and a copy of the approved plans to every inspection.

The three-permit requirement also affects cost-of-delay. If plan review takes 5 weeks instead of 3, and your contractor is billing hourly for site supervision, that's an extra $500–$1,000 in labor costs. If the project is weather-dependent (e.g., exterior duct work), delays can push you into rainy season. Many homeowners in San Bruno underestimate the permitting timeline and budget 4–6 weeks from application to first inspection; plan 8–10 weeks from first application to final sign-off. Requesting expedited review (if available) may cost $100–$300 extra but can compress the timeline by 1–2 weeks.

GFCI, small-appliance circuits, and lead paint in San Bruno kitchens

San Bruno enforces California Title 24 and NEC Article 210 strictly, which means every kitchen remodel must include two dedicated 20-amp small-appliance branch circuits for counter receptacles, and every outlet within 6 feet of a sink must be GFCI-protected. This is non-negotiable and is the #1 reason electrical plans are rejected in the city. Many homeowners assume they can add a few outlets to an existing 15-amp circuit or run a single 20-amp circuit; San Bruno's electrical inspector will flag this immediately. The code requires two 20-amp circuits so that a toaster and microwave can run simultaneously without tripping a breaker. Both circuits must originate from the main panel (or a sub-panel if you're doing a major remodel) and must be labeled on the single-line diagram. Each outlet on these circuits must be a 20-amp-rated receptacle (horizontal slots on the neutral side, not the hot side). GFCI protection can be provided either by GFCI breakers in the panel (one breaker per circuit, costs $50–$80 per breaker) or by GFCI outlets (one outlet per location, costs $15–$25 per outlet). GFCI outlets offer more flexibility because you can protect multiple outlets downstream from a single GFCI outlet, but the first GFCI outlet in the circuit must be at the location closest to the sink. If you're unsure, specify GFCI breakers in the panel — it's cleaner and eliminates ambiguity with the inspector.

A second common issue is counter-outlet spacing. The NEC requires receptacles on kitchen counters to be spaced no more than 4 feet apart (48 inches), measured along the counter edge. San Bruno interprets this as: every section of counter between two walls or appliances must have at least one outlet within 4 feet. Island counters also require outlets on all sides. Many remodels fail the rough-electrical inspection because the outlet spacing diagram is missing or incorrectly measured. When you submit your electrical permit, include a kitchen floor plan with dimensions of all counter sections, outlet locations marked, and spacing measurements labeled (e.g., '4 ft 2 in from corner' or 'under island center'). This single document prevents a rejection cycle. Your electrician should prepare this as part of the plan package; if they don't, request it before submitting the permit application.

Lead-based paint is a federal issue in San Bruno homes built before 1978 (which includes most kitchens in the city — the median home age is late 1950s). Before work begins, the property owner must receive an EPA-approved disclosure form acknowledging that the home may contain lead paint, and both owner and contractor must sign it. Work can proceed during renovation, but the contractor must follow lead-safe work practices (containment, HEPA vacuuming, no dry scraping or sanding of painted surfaces). The disclosure costs $0 (it's a form), but failure to provide it is a federal violation and can result in EPA fines up to $16,000 per violation. Many contractors assume the homeowner will handle this; clarify who is responsible before signing the construction contract. If you're hiring a contractor, ask them to provide the signed disclosure as part of the permit package. The San Bruno Building Department does not enforce lead-paint compliance (that's EPA), but they will ask to see the disclosure in the project file during final inspection. If it's missing, final sign-off is delayed.

Common questions

Do I need a permit for a kitchen remodel if I'm just replacing appliances and cabinets in the same locations?

No, if you're swapping out appliances and cabinets without moving walls, plumbing, or electrical outlets, that's exempt from permitting. However, if the new appliance requires a different voltage or gas configuration (e.g., a new electric range where you had gas), you'll need an electrical or gas permit. Also, if your home was built before 1978, you must obtain a lead-paint disclosure before work starts, even though no permit is required.

What's the cost of a full kitchen remodel permit in San Bruno?

Permit fees (building, plumbing, electrical combined) typically range from $600 to $1,500, depending on the scope and project valuation. The building permit is usually 1.5% of the project cost (minimum $150), plumbing is $250–$400 (base fee plus per-fixture charges), and electrical is $350–$500. These are city fees only; they do not include the cost of design, engineering, or contractor labor.

Can I pull permits as an owner-builder, or do I need a licensed contractor?

California Building & Professions Code Section 7044 allows owner-builders to pull permits for work on their own residential property, but you are prohibited from performing any electrical or plumbing work yourself — those must be done by licensed contractors. You can do framing, drywall, finishing, and cosmetic work, but electrical and plumbing require a state-licensed electrician and plumber. If you attempt unlicensed electrical or plumbing work, the city will issue a stop-work order and require a licensed contractor to correct it at added cost.

How long does plan review take in San Bruno?

San Bruno's plan-review timeline is 4–6 weeks from the date the application is deemed complete. The clock starts when all three permits (building, plumbing, electrical) are submitted together and the city confirms no missing documents. If the submission is incomplete, it's rejected and the timeline resets when you resubmit. If you want faster review, contact the building department to ask about expedited-review options (may add a fee of $100–$300).

What's the #1 reason kitchen remodel plans are rejected in San Bruno?

Missing or incorrect GFCI outlet labeling and small-appliance circuit sizing. The electrical plan must clearly show two dedicated 20-amp circuits for kitchen counters, with every outlet within 6 feet of a sink labeled as GFCI-protected. If this is not shown on the plan, the city's electrical reviewer will reject it and request a revised diagram. Resubmission delays approval by 1–2 weeks.

Do I need a structural engineer for a kitchen wall removal?

Yes, San Bruno requires a structural engineer's design for any load-bearing wall removal, with no exceptions. Even if a contractor claims the wall is 'non-bearing,' the city will require verification. The engineer provides a design drawing and stamp confirming the new beam size, bearing points, and connections per the California Building Code. Engineer costs range from $800 to $1,500 for a simple kitchen wall opening.

If I move my kitchen sink, what inspections will I need?

A sink relocation requires a rough-plumbing inspection (after drain, supply, and vent lines are roughed in but before drywall), and a final inspection (after all work is complete). If the sink requires new electrical outlets, you'll also have a rough-electrical inspection. San Bruno's inspector will verify that the drain slope is correct (1/4 inch to 1/2 inch per foot), the trap arm is under 3.5 feet, and the vent connection is to an existing stack within 5 feet of the trap.

Can I install a range hood that vents into my attic instead of through an exterior wall?

No. San Bruno Building Code (adopting the California Building Code) requires all range hoods to be ducted to the exterior, terminating at least 10 feet from windows, doors, and air intakes. Venting into the attic or crawlspace is not permitted because it introduces moisture and combustion byproducts into unconditioned spaces, creating mold and structural damage risk. If your kitchen layout makes exterior ducting difficult, a booster fan or ductless recirculating hood is an alternative, but the latter is less effective and requires frequent filter changes.

What happens at the final inspection for a kitchen remodel?

The final inspection verifies that all work is complete and meets code: cabinets are installed, countertops are in place, all outlets and switches are operational and GFCI-protected where required, plumbing fixtures are connected and draining properly, gas lines are capped or connected with shutoff valves, and range hood is ducted and operational. The inspector also verifies that any structural repairs (beam installation, drywall) are complete and that the project matches the approved plans. If everything passes, the city issues a 'Certificate of Occupancy' or final approval, and your home is legally occupied with the new kitchen.

Will an unpermitted kitchen remodel affect my home sale or refinance?

Yes, significantly. An unpermitted kitchen remodel will be disclosed on the Title-24 compliance notice during a home sale, and many buyers will demand a $5,000–$15,000 escrow holdback to cover the cost of bringing it into compliance or removal. If you apply for a refinance or home-equity line, the lender's appraiser will identify unpermitted work, and the lender will likely deny financing until the work is permitted and inspected. Correcting unpermitted work after the fact is more expensive than permitting it upfront — expect $2,000–$5,000 in additional costs for re-inspection and possible corrections. The safest path is to permit the work before you start.
