The short answer
Which permits does a Seattle kitchen remodel need?
In Seattle, the permit question shapes most kitchen jobs. SDCI says installing kitchen cabinets needs no permit, but new or altered wiring needs an SDCI electrical permit, plumbing and gas changes go through Public Health, Seattle & King County, and any work on a load-bearing wall needs a building permit. Non-structural kitchen work in a single-family home typically fits SDCI's faster subject-to-field-inspection (STFI) permit, where the inspector checks code on site. More than half of Seattle's housing units were built before 1980 (Census ACS 2024), so plan for older wiring, lead-safe work and a range hood that meets the city's exhaust rule.
Settle one fact early: gas or electric. It sets the hood SDCI's checklist asks for, and a gas range that moves brings a county gas permit and a licensed gas piping mechanic.

Finish refresh: inclusions & limits
Covers new doors or refaced boxes, counters, backsplash, an in-place sink and faucet swap, and light fixtures on existing boxes. SDCI does not require a permit to install kitchen cabinets or for minor alterations of $6,000 or less in any six-month period, but connecting new wiring or equipment still needs an electrical permit. In a pre-1978 house, a firm that disturbs painted surfaces needs RRP certification, Washington's lead-safe renovation license.
Full replacement, same layout: inclusions & limits
Includes demolition, new cabinets and counters, rewiring to current kitchen circuit rules, and reconnecting sink, dishwasher and range. SDCI says non-structural interior alterations in single-family homes typically qualify for an STFI permit. Plumbing permits come from Public Health, Seattle & King County, not SDCI. Where framing cavities are exposed, SDCI's energy checklist requires filling them with insulation, so that belongs in the bid.
Change the layout: inclusions & limits
Adds structural work, new drain and vent routes, island power, a relocated gas line and a new hood duct path. SDCI's Tip 316, its guide to the fast STFI permit, allows STFI openings in bearing walls that carry only one story plus roof, with beam spans up to 14 feet. Inside Seattle, gas piping must be installed by the owner or a holder of a Seattle Gas Piping Mechanic License. Carry design and engineering as separate lines.
What a kitchen remodel costs in Seattle in 2026.
A Seattle kitchen can need a building permit, an electrical permit and a county plumbing permit before the first cabinet goes in, and the bids for it vary just as widely. On 94 kitchen permits SDCI took in for single-family homes and duplexes since September 2024, owners declared a median of $45,000, and half of them landed between $20,000 and $86,124.
$45,000
That sample is small for a city this size, and there is a reason. SDCI says installing kitchen cabinets needs no permit, new wiring goes on a separate electrical permit, and plumbing goes to Public Health, Seattle & King County, so many like-for-like remodels only need trade permits and never show up in this count. The 2025 Cost vs Value report fills in the rest: $32,271 for a midrange minor kitchen remodel in Seattle, $95,542 for a midrange full remodel and $188,401 for an upscale one. A permit records the project cost estimated for SDCI; a bid for your kitchen also carries the hood duct, the old wiring and what sits behind the plaster.

| Budget line | Define it | Watch for |
|---|---|---|
| Permits and inspections | SDCI building permit fees are based on project value, electrical fees depend on what is installed, and plumbing and gas permits are billed separately by Public Health. | SDCI adds a technology fee to its permits. Ask whether permit fees are inside the bid or passed through at cost. |
| Cabinets, counters and appliances | Boxes, fronts, slab fabrication and the appliance package. JLC's 2025 Cost vs Value report lists a Seattle midrange minor kitchen remodel at $32,271 and a midrange major remodel at $95,542. | Those are model projects, not quotes. A hood that meets SDCI's capture efficiency rule (the share of cooking fumes it actually catches) can cost more than the one in the showroom photo. |
| Opened walls and older systems | Rewiring, insulation of exposed cavities, lead-safe work in pre-1978 homes, and repairs found behind old plaster or paneling. | More than half of Seattle housing units predate 1980, per Census ACS. Ask for unit prices for rot, old wiring and insulation before demolition starts. |

What a kitchen remodel budget buys in Seattle.
$20,000
The bottom quarter of Seattle kitchen permits. Most jobs at this level keep the layout and plumbing and change fronts, counters, backsplash, the sink and faucet in place, and light fixtures on existing boxes. Cabinets need no SDCI permit, but new wiring still needs an electrical permit. In a pre-1978 house the crew also needs RRP, Washington's lead-safe renovation certification.
$30,000 to $45,000
From the Cost vs Value midrange minor remodel at $32,271 up to the permit median of $45,000. A same-footprint replacement starts here: new cabinets, counters and appliances, and rewiring to current kitchen circuit rules. It usually runs on an STFI permit plus trade permits. Where framing cavities open up, SDCI's energy checklist requires insulating them, so that line belongs in the bid.
$85,000 to $130,000
The top quarter of permits, from $86,124 up to where the top tenth begins at $125,130. The Cost vs Value midrange full remodel, at $95,542, sits in between. This is where layouts change: a moved sink or range, an island, or an opening in a bearing wall. Tip 316, SDCI's guide to the fast STFI permit, allows that opening only in walls carrying one story plus roof, with beams up to 14 feet.
$185,000 and up
The 2025 Cost vs Value report prices its upscale full kitchen remodel in Seattle at $188,401. Money at this level goes into cabinetry, the appliance package and design time. A big gas range raises the hood bar too: 80 percent capture or 250 CFM, vented outside.
What a Seattle kitchen permit value leaves out.
The $45,000 median covers the SDCI building permit only. The wiring goes on a separate electrical permit and the plumbing and gas on a county permit, so none of that work shows in the permit value. The figure is also what the applicant wrote down for SDCI, which sets building permit fees on project value. A contractor's price has to cover labor, materials, overhead and margin, plus a cushion for what the walls hide.
So line the bids up item by item. One may include the SDCI building or STFI permit with its technology fee, the electrical permit, the county plumbing permit and a gas line moved by a Seattle licensed gas piping mechanic. It may also price insulation for every opened cavity and lead-safe work in a pre-1978 house. Another may carry half of that as change orders. More than half of Seattle's housing units were built before 1980. Electricians in the Seattle-Tacoma-Bellevue metro earned a median $48.93 an hour in May 2025 and carpenters $36.74, and a contractor's hourly rate covers far more than the paycheck.

Make the guide yours
Refresh, replace or reconfigure: sizing a Seattle kitchen
In an older Seattle house, the scope you pick decides which walls get opened, and every opened wall brings its own obligations. SDCI's energy checklist requires insulating exposed framing cavities, a pre-1978 house calls for an RRP certified firm, and a moved range needs a licensed gas piping mechanic. A refresh avoids most of that. A new layout takes all of it on.
No scope selected. The guide and checklist are available without choosing a project tier or leaving contact details.
Resolve the old systems before ordering the new kitchen
In an older Seattle kitchen, the hood is often what forces the plan to change. SDCI's checklist says a hood over a gas range must catch at least 80 percent of the cooking fumes or move 250 cubic feet of air a minute (CFM). Over an electric range the bar is 60 percent or 160 CFM, and either way it vents straight outside. If today's hood only recirculates, settle the duct route before the cabinet sizes are final.
Cabinets alone need no SDCI permit, so a bid that lists only cabinets and counters has not priced the systems yet. New circuits go on an SDCI electrical permit. A moved gas line goes on a Public Health, Seattle & King County permit, run by the owner or a Seattle licensed gas piping mechanic.

A decision to work through · illustrative scenario
Swapping an electric range for gas
The owners of an older house want a gas range where an electric one stood. That means a new gas line, a county gas permit and a hood that meets the 80 percent or 250 CFM rule, vented outside. The duct path decides which wall cabinets can stay.
Before you compare bids: Ask each bidder for the hood model and its rating, where the duct leaves the house and who pulls the gas permit, each on its own line.
How long do Seattle kitchen permits take, and what comes first?
The calendar for a Seattle kitchen starts before the permit. The Seattle Services Portal shows what earlier owners filed, and SDCI's free 20-minute coaching session can settle whether the job fits an STFI permit. That choice matters: STFI screening takes a few days, while full review targets 2 to 3 weeks for a simple initial review and 8 weeks for a complex one.
- 1
Check the house first. Look up past permits and violations on the Seattle Services Portal, and find out whether the wall you want to open carries load. If you are unsure the job fits an STFI permit, book SDCI's free 20-minute coaching session.
- 2
Permit, then order. SDCI says STFI screening takes a few days, while full review targets 2 to 3 weeks for simple and 8 weeks for complex initial reviews. Order cabinets once the permit route and the hood duct path are settled.
- 3
Build and inspect. Most SDCI electrical permits need cover, service and final inspections, and the county plumbing program asks for several business days after an inspection request. Keep the permit posted on site; it is valid for 18 months.
Ask for separate dates for design, permit review, ordering and construction.
What a Seattle kitchen bid should list before you sign
Seattle kitchen bids can differ on the parts owners never see. Check which of the three or four permits are included, whether the hood meets SDCI's capture or airflow rule, and who insulates the cavities once walls open. Ask for each on its own line. It is also the right moment to check the contractor's Washington L&I registration, before anything is signed.
- A written permit list: SDCI building or STFI, SDCI electrical, county plumbing, and gas if it moves.
- Hood model with its capture efficiency or CFM (airflow) rating, and where the duct exits the house.
- Contractor's Washington L&I registration and RRP lead-safe certification if the house predates 1978.
- A line item for insulating every wall cavity that gets opened, per SDCI's energy checklist.
- Smoke and carbon monoxide alarm work that SDCI checks at final, included in the electrical scope.

Permits, costs and resale: Seattle kitchen questions
Buyers can look up what you did. SDCI keeps permit history by property, and it lists resale value and insurance coverage among its reasons to get a permit. The questions below start with the hood, which shapes an older Seattle kitchen's layout more than most owners expect.
Why does the hood come before the cabinets in a Seattle kitchen?
Because its duct has to go somewhere. SDCI's checklist asks for a hood that meets its capture or airflow rule and vents outside. If the duct runs through a wall cabinet or a joist bay, the cabinet layout changes. Settle the duct path first, then order the cabinets.
Do you need a permit to remodel a kitchen in Seattle?
Usually for some part of it. SDCI lists installing kitchen cabinets and minor alterations of $6,000 or less in any six-month period as exempt, but new or altered wiring needs an SDCI electrical permit, plumbing changes need a Public Health, Seattle & King County permit, and work on load-bearing supports always needs a building permit. Non-structural interior work in a single-family home typically qualifies for the faster STFI route.
What is the typical cost of a kitchen remodel in Seattle?
On 94 Seattle kitchen permits for single-family homes and duplexes since September 2024, owners declared a median project cost of $45,000, with half between $20,000 and $86,124. Many like-for-like remodels need only trade permits and are not in that count. The 2025 Cost vs Value report prices a midrange minor remodel in Seattle at $32,271 and a midrange full remodel at $95,542. A budget of $32,000 to $45,000 covers a same-footprint replacement.
Do buyers ask whether a Seattle kitchen was permitted?
They can check. SDCI keeps permit history by property, searchable through its Research a Project page and the Seattle Services Portal, and SDCI lists resale value and insurance coverage among its reasons to get a permit. If an earlier owner remodeled without one, ask SDCI how to handle that work before you build over it.
Check contractor credentials with Washington Labor & Industries. Match the business identity and scope to the proposal.
