The Short Answer
A full kitchen remodel in Danville requires a building permit if you're moving walls, relocating plumbing, adding electrical circuits, modifying gas lines, or cutting exterior walls for range-hood venting. Cosmetic-only work—cabinet/countertop swap, appliance replacement on existing circuits, paint—is exempt.
Danville sits in Contra Costa County's coastal hillside zone, and the city enforces the current California Building Code (based on 2022 IBC) with local amendments that emphasize structural review and fire-safety compliance for kitchen wall removals. Unlike some neighboring East Bay cities that allow over-the-counter plan review for minor kitchens, Danville typically routes full kitchen remodels through full plan review—meaning your contractor submits plans (building, electrical, plumbing) to the city, the city reviews for 2–3 weeks, issues a mark-up or approval, and then you revise and resubmit if needed. Danville's building department does not have a 'limited kitchen' exemption tier; any wall move, any plumbing relocation, any new circuit, or any range-hood exterior vent triggers the full three-permit stack (building, electrical, plumbing). The city also enforces strict GFCI and small-appliance circuit rules per NEC 210.12 and 210.8—common rejection reason is missing the two 20-amp small-appliance branch circuits shown on the electrical plan. Lead-paint disclosure is mandatory if your home was built before 1978, and Danville will not issue a building permit until you've provided lead-hazard compliance documentation.

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

Danville kitchen-remodel permits — the key details

Danville requires a building permit for any kitchen remodel that involves structural changes, plumbing relocation, electrical circuit additions, gas-line modifications, or range-hood exterior venting. The California Building Code (adopted statewide, but Danville enforces it strictly in the hillside context) mandates that any wall removal over 8 feet must be engineered if it's load-bearing—Danville's building department will not sign off on a wall-removal plan without a licensed structural engineer's letter or detailed beam calculation (IRC R602.7.2). Full kitchen remodels almost always require three separate permits: building (structural/general), electrical, and plumbing. A fourth permit for mechanical (HVAC range-hood vent) is sometimes required if you're adding a powered range hood with exterior ducting. The city's online portal allows you to download permit applications and fee schedules, but Danville does not accept 100% electronic submittals for full kitchens—you must print, sign, and deliver plans in person or via mail to the city's permit office, which can add 1–2 weeks to initial intake.

Electrical work in a Danville kitchen is governed by the National Electrical Code (NEC), adopted by California and enforced locally. IRC E3701 requires that all receptacles serving counter surfaces in the kitchen be GFCI-protected and spaced no more than 48 inches apart (outlet center to outlet center). This is not a suggestion; it's a code-compliance line item that inspectors check on the rough electrical inspection. You must also show two 20-amp small-appliance branch circuits (IRC E3702) dedicated to serving countertop receptacles and the refrigerator—these cannot be combined with other circuits, and they must be shown on your electrical plan with clear wire sizing (typically 12 AWG for 20 amps). Common rejection reason: the electrician submits a plan that omits one of these circuits or shows GFCI protection at only some outlets, not all. The rough electrical inspection happens after framing but before drywall, and the inspector will not pass the job until every GFCI outlet is tested and verified live.

Plumbing in a kitchen remodel triggers two code sections: IRC P2722 (kitchen sink drain requirements) and IRC P2704 (trap arm and vent). If you're relocating your kitchen sink, the plumbing plan must show the new trap location (typically a P-trap under or beside the new sink cabinet), the vent-stack connection, and the main drain routing. Danville's building department frequently rejects plumbing plans that omit the vent detail or show a trap arm longer than 5 feet without a vent (which creates a siphon risk). A licensed plumber must sign and stamp the plumbing plan; Danville does not accept self-designed plumbing submittals from homeowners. The rough plumbing inspection occurs after framing and before the trap arms are covered by cabinetry—the inspector will verify trap depth (should be 1–4 inches of water seal), vent routing, and compliance with the trap-arm length rule. If you're adding a gas cooktop or range, the gas line must be sized and labeled on the plumbing plan, and a separate gas-line inspection is required.

Range-hood exterior venting is a frequent source of rejections in Danville. If you're installing a new range hood with exterior ducting, the plan must show the duct routing from the hood through the exterior wall, including the exterior wall cap detail (damper and screen required per IRC M1505.2). Many homeowners and contractors assume they can just run a 6-inch flex duct through the wall; the city will reject this unless you show the transition fitting, the cap termination, and the distance from the wall (typically 12 inches minimum from roof or overhang). The range-hood vent is often inspected as part of the mechanical permit, not the building permit, so you may need to apply for a separate mechanical permit ($100–$200 in addition to building and electrical fees). The final inspection for range-hood venting happens after drywall but before trim, so the inspector can visually confirm the duct routing and cap installation.

Lead-paint disclosure is mandatory in Danville for any home built before 1978. You cannot pull a building permit without providing a Lead-Based Paint Disclosure form (federally required under 42 U.S.C. § 4852d), signed by all parties, stating that you understand the risks and have had the opportunity to inspect or test for lead. If your home was built before 1978 and you're doing a remodel that disturbs painted surfaces (cabinets, walls, trim), Danville may require you to hire a lead-certified contractor or post a lead-safe work practices plan. This adds cost and timeline but is non-negotiable. The building department will not issue a permit if the lead disclosure is missing or unsigned.

Three Danville kitchen remodel (full) scenarios

Scenario A
Galley kitchen, new island, wall relocated 18 inches—Danville foothills ranch home, 1972 build, load-bearing wall
You're removing a 10-foot section of the wall between the kitchen and dining room to open up the space and add a new island. The wall is load-bearing (runs perpendicular to floor joists, supports the roof above). This absolutely requires permits. First, you must hire a structural engineer (cost: $800–$1,500) to design a beam or lintel to carry the roof load. The engineer signs and stamps a structural detail drawing showing beam size, moment connections, and bearing points. Danville's building department will not approve your wall removal without this letter. Next, you submit four sets of plans: building (with the engineer's beam detail), electrical (showing new circuits to the island and GFCI outlets spaced 48 inches apart on the island perimeter and existing wall), plumbing (if relocating the existing sink or adding a second fixture on the island), and mechanical (if you're adding a powered range hood with exterior duct). Total permit fees: $400–$800 (based on estimated project valuation, typically 1–2% of construction cost). Plan review takes 2–3 weeks. Once approved, you have framing inspection (inspector verifies beam is installed per engineer's detail), rough electrical and plumbing inspections (before drywall), drywall inspection, and final inspection. Timeline: 6–8 weeks from permit issuance to final sign-off. The home was built in 1972, so lead-paint disclosure is required; you'll need a lead-safe work practices plan if the wall contains original paint.
Structural engineer letter required | Beam sizing + moment connections | Full building review 2–3 weeks | Framing + rough electrical + rough plumbing + final inspections | GFCI on island receptacles + 48-inch spacing | $800–$1,500 engineer fee | $400–$800 permit fees | 6–8 week timeline | Lead disclosure mandatory (pre-1978 home)
Scenario B
Cabinet and countertop swap, new range hood with exterior duct, existing location—Danville hillside mid-century home, 1955 build, new electrical circuits for hood
You're replacing cabinets and countertops in-place (no wall moves, no plumbing relocation) but adding a new powered range hood with ducting to the exterior. This still requires permits because you're cutting through the exterior wall and adding an electrical circuit. The electrical plan must show a 20-amp single-pole breaker dedicated to the range hood motor, wired in 12 AWG cable, with the circuit originating from the main panel. The range hood itself must be GFCI-protected (some range hoods have built-in GFCI, but the plan must specify). The mechanical permit covers the duct routing: you must show the duct path from the hood, through the interior wall/soffit, through the exterior wall, and the exterior cap detail (damper, screen, 12-inch clearance from roof). Danville's building and mechanical departments will cross-check the duct size (typically 6 inches for a standard 30-inch range) and the cap termination. Permit fees: $250–$400 (electrical) + $150–$250 (mechanical) = $400–$650 total. Plan review: 1–2 weeks (quicker than a full kitchen because no structural or plumbing review). Inspections: rough electrical (after framing but before drywall), mechanical (before final drywall, to verify duct routing), and final (range hood and duct installed, cap visible, circuit live). The home was built in 1955, so lead disclosure applies; if you're removing old cabinets with painted surfaces, lead-safe work practices are required. Timeline: 4–5 weeks from permit issuance to final.
No structural work (no walls moved) | Electrical permit only for range-hood circuit | Mechanical permit for duct + exterior cap | GFCI protection on range hood circuit | Exterior duct cap with damper + screen required | Duct size 6 inches, 12-inch clearance from roof | $250–$400 electrical permit | $150–$250 mechanical permit | 1–2 week plan review | Rough electrical + mechanical + final inspections | 4–5 week timeline | Lead disclosure (pre-1978 home)
Scenario C
Full kitchen remodel: new peninsula, plumbing relocation (sink to opposite wall), gas cooktop replacement, new small-appliance circuits—Danville downtown bungalow, 1925 build, owner-builder
You're doing a complete gut: moving the sink to the opposite wall, installing a new gas cooktop where the old electric range was, adding a peninsula with a second sink and seating. This is three separate permits minimum (building, electrical, plumbing), potentially four if you're adding a mechanical duct. As owner-builder, Danville allows you to pull the building permit yourself (you have an Owner-Builder exemption per California B&P Code § 7044), but you cannot do the electrical or plumbing work yourself—these subtrades must be licensed contractors who sign and stamp the plans. The building plan must show the new peninsula layout, any wall modifications, and cabinet/counter details. The electrical plan must show the two 20-amp small-appliance branch circuits (one for countertop receptacles, one for the refrigerator), GFCI protection on all countertop receptacles spaced no more than 48 inches apart, a 40-amp circuit for the gas range hood (if adding a powered hood), and the gas cooktop supply line (gas lines are shown on plumbing plans, not electrical, but the cooktop's igniter may require a dedicated circuit). The plumbing plan must show the new sink trap location, vent routing, main drain connection, and a new gas supply line sized for the cooktop. Lead disclosure is critical: the home was built in 1925, so all original painted surfaces must be treated as lead hazard. You'll need a lead-safe work practices plan (cost: $200–$500) and possibly lead-certified contractors. Permit fees: $500–$800 (building, estimated $40K–$60K project valuation) + $200–$400 (electrical) + $200–$400 (plumbing) = $900–$1,600 total. Plan review: 3–4 weeks (full scope). Inspections: framing (if you're modifying any walls), rough electrical, rough plumbing, gas-line (if new gas supply), drywall, final. Timeline: 7–10 weeks from permit issuance to final, plus lead remediation work.
Owner-builder can pull building permit, licensed electrician + plumber required | Two 20-amp small-appliance circuits required | GFCI on all countertop receptacles | New sink plumbing relocation (trap arm, vent, main drain) | Gas cooktop supply line on plumbing plan | Range hood circuit (if powered hood) | Lead-safe work practices plan (1925 home) | Full plan review 3–4 weeks | Framing + rough electrical + rough plumbing + gas-line + drywall + final inspections | $900–$1,600 permit fees | 7–10 week timeline | Lead disclosure mandatory

Danville's plan-review process and why full kitchens don't qualify for over-the-counter approval

Danville's building department does not offer a 'short-form' or 'over-the-counter' review for full kitchen remodels, unlike some neighboring East Bay cities (e.g., Walnut Creek, Concord). This means your contractor cannot walk in with plans, get a thumbs-up on the spot, and start work the next day. Instead, Danville routes all kitchen remodels through formal plan review: your contractor submits four sets of plans (building, electrical, plumbing, and sometimes mechanical) to the permit office; the plans are assigned to a plan reviewer; the reviewer checks for code compliance over 2–3 weeks; and then the city issues either an approval or a 'conditional approval' (mark-up sheet listing deficiencies). You must revise and resubmit, adding another 1–2 weeks to the cycle. This process exists because Danville sits in a hillside/foothills context (climate zone 3B–3C coast, 5B–6B mountains in the higher elevations) where seismic and fire-load concerns are heightened, and the city enforces strict structural review for any wall modification.

The submission requirements are: (1) building plan set (floor plan showing cabinet/appliance layout, wall sections if walls are moved, details of any beam or lintel, sink location, range-hood ducting if applicable); (2) electrical plan set (load calculation, panel diagram, circuit schedule, receptacle spacing diagram, GFCI locations, small-appliance circuit details); (3) plumbing plan set (isometric or plan view of drain, supply, and vent lines, trap and vent details, gas-supply line if applicable); (4) mechanical plan set (if range hood is powered and vented to exterior, showing duct sizing, routing, and cap detail). All plans must be signed and stamped by the licensed contractor (or structural engineer if walls are removed). Danville's portal allows download of blank applications, but final submittal is in-person or by mail; the city does not accept email or digital-only submittals for full kitchens. This adds 1–2 weeks if you're mailing from a distance or if the permit office is busy.

Once plans are approved and permits are issued, you schedule inspections in sequence: framing inspection (if walls are moved), rough electrical (after framing, before drywall), rough plumbing (after framing, before drywall), mechanical inspection (if range-hood duct), drywall inspection, and final inspection. Each inspection must pass before you move to the next phase. If the rough electrical inspection fails (e.g., GFCI outlets not installed, receptacle spacing wrong, small-appliance circuits missing), the inspector will mark the items non-compliant, and you cannot cover walls with drywall until corrections are made. This can add 1–2 weeks per failed inspection. Plan for a total timeline of 6–10 weeks from permit issuance to final sign-off.

Electrical and GFCI compliance: the most common rejection in Danville kitchens

The most frequent reason Danville's building department rejects kitchen electrical plans is missing or incomplete GFCI protection and small-appliance branch circuits. The National Electrical Code (NEC) and California's adoption thereof require that all countertop receptacles in a kitchen be GFCI-protected (IRC E3801.1). This means every outlet serving counter surfaces (within 6 feet of the sink, on islands, on peninsula counters) must either be a GFCI outlet itself or be on a GFCI-protected branch circuit. Many electricians submit plans showing GFCI protection at only the first outlet on a circuit ('GFCI at outlet, remainder protected'), but Danville's inspectors will fail this because it doesn't account for downstream outlets if the GFCI device fails. The best practice (and what Danville expects) is to install GFCI outlets at each location or to use a GFCI breaker at the panel and then regular outlets downstream. The spacing rule (NEC 210.52(C)(1)) states no point on a countertop can be more than 48 inches (measured horizontally along the counter surface) from an outlet. This means on a 10-foot counter, you need at least 3 outlets. On an island, outlets must be spaced 48 inches apart around the perimeter.

The second common rejection is missing or misplaced small-appliance branch circuits. NEC 210.52(B) and IRC E3702 require a minimum of two 20-amp small-appliance branch circuits serving countertop receptacles and the refrigerator. These are separate, dedicated circuits that cannot serve any other loads (no lighting, no range hood, no dishwasher). Many electricians combine these or show only one circuit, and Danville will not approve the plan. The electrical plan must explicitly label these circuits on the panel schedule (e.g., 'Circuit 3 & 4: 20A small appliance #1 & #2'), and the receptacles they serve must be called out on the plan. If you're adding an island, the island receptacles typically go on one of these two small-appliance circuits; the refrigerator and existing countertop receptacles share the other. The third issue is gas-cooktop igniter circuits. If you're installing a gas range with an electric igniter, that igniter requires a separate 120-volt, 15- or 20-amp circuit. Some electricians try to piggyback this onto a small-appliance circuit, which is code-non-compliant. Danville's inspectors will catch this and require a separate circuit breaker and wire run.

Common questions

Do I need a permit if I'm just replacing cabinets and countertops in the same location with no plumbing or electrical changes?

No, cosmetic-only cabinet and countertop replacement with no plumbing relocation, no new electrical circuits, and no structural changes does not require a permit in Danville. If you're also replacing appliances on existing circuits and outlets, that's still exempt. However, if you're adding a new range hood with exterior ducting, you'll need mechanical and electrical permits for that component.

What if I'm removing a non-load-bearing wall to open up my kitchen?

A non-load-bearing wall (e.g., a wall that runs parallel to floor joists and doesn't support anything above) still requires a building permit in Danville, even though you don't need structural engineering. The permit is required to document the work and ensure compliance with code (framing details, fire blocking, electrical/plumbing routing through the wall). You'll still go through plan review and inspections. If the wall contains any plumbing, electrical, or gas lines, those must be rerouted per code and shown on the building plan.

Do I need a separate mechanical permit for a range hood, or is it covered under the building permit?

In Danville, if you're adding a new range hood with exterior ducting, you typically need a separate mechanical permit ($150–$250) in addition to the electrical permit. The building permit covers the structural work (cutting through walls); the electrical permit covers the circuit and power supply; the mechanical permit covers the duct sizing, routing, and exterior cap. Some contractors bundle all three under the building permit, but Danville's current practice is to separate them, so plan for three distinct permit applications and inspections.

Can I pull the building permit myself as owner-builder, or do I need a contractor?

Yes, California law (B&P Code § 7044) allows owner-builders to pull building permits for residential remodels in their own home. However, Danville requires that electrical and plumbing work be performed and signed off by licensed contractors. You cannot do electrical or plumbing work yourself even if you pull the building permit. You can do demolition, framing, drywall, painting, and finish carpentry yourself, but the licensed trades must sign their respective permit plans and inspections.

How long does plan review take for a full kitchen remodel in Danville?

Plan review typically takes 2–3 weeks from the time you submit complete, signed plans to the permit office. If the city finds deficiencies (missing GFCI details, incomplete plumbing vent routing, structural engineer letter missing), they will issue a mark-up sheet, and you'll need to revise and resubmit, adding another 1–2 weeks. Budget 3–4 weeks total for a first-time approval and issuance.

What is the most common reason Danville rejects kitchen electrical plans?

Missing or incomplete GFCI protection and missing small-appliance branch circuits. The code requires GFCI protection on all countertop receptacles (spaced no more than 48 inches apart) and a minimum of two dedicated 20-amp small-appliance branch circuits. Many submitted plans show GFCI protection at only some outlets or combine small-appliance circuits with other loads. Danville's plan reviewer will reject these and require resubmission with full GFCI and dedicated small-appliance circuit labeling.

Do I need a lead-paint disclosure for a 1965 kitchen remodel?

Yes, absolutely. Any home built before 1978 is presumed to contain lead-based paint under federal law. Danville requires a signed Lead-Based Paint Disclosure form before issuing any permit, and if your remodel disturbs painted surfaces (walls, cabinets, trim), you may need a lead-safe work practices plan or a lead-certified contractor. The disclosure is non-negotiable; the building department will not issue a permit without it.

If I'm adding an island with a sink, does that require a second plumbing permit?

No, there is only one plumbing permit for the entire kitchen remodel, but the plumbing plan must show all drain, supply, and vent lines including the island sink. The plan must detail the new sink trap location, the vent routing back to the main stack or wet vent, and the supply lines (hot and cold). The plumbing inspector will verify all of this during the rough plumbing inspection.

What happens during the rough electrical inspection in a kitchen remodel?

The rough electrical inspection occurs after framing but before drywall. The inspector will verify that all circuits are run per the approved electrical plan, that GFCI outlets are installed at every required location (countertop and elsewhere), that small-appliance circuits are properly labeled and separated, that the range-hood or cooktop circuit is installed with correct breaker size and wire gauge, and that all boxes and connections are code-compliant. The inspector will physically test GFCI outlets with a tester device to confirm they are live and functioning. Any non-compliances must be corrected before drywall can be hung.

What's the typical cost for a full kitchen remodel permit in Danville?

Danville's permit fees are typically 1–2% of the estimated project valuation. For a full kitchen remodel valued at $40,000–$60,000, expect $400–$1,200 in permit fees (building + electrical + plumbing combined). If you need structural engineering for a wall removal, add $800–$1,500. If you need a lead-safe work practices plan, add $200–$500. Timeline and total cost depend heavily on whether walls are load-bearing and whether you're relocating plumbing.
