Kitchen remodeling permits, King County
Do You Need a Permit to Remodel a Kitchen?
A kitchen needs a permit when plumbing, a gas line, wiring or a wall moves. Replacing cabinets and countertops in place needs no building permit in Bellevue, Redmond, Kirkland, Sammamish or Bothell. Seattle's code exempts cabinets and does not name countertops. Trade work can need its own permit. Ask Issaquah and Renton first; neither lists a cabinet exemption.
Every rule below comes from the city's own code or permit page, read in October 2026. To have one team design the kitchen and file its permits, Book a Consultation.
Which kitchen remodel work needs a permit in King County?
The city pages read for this guide name four kinds of kitchen work that bring a permit: moving or removing a wall, moving plumbing or adding a gas line, adding or moving electrical circuits, and cutting a new or wider window. Each city writes the rule into its own code. Bothell Municipal Code 20.02.095 (read October 2026) is typical: a permit is needed to "construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system". Renton Municipal Code 4-5-060E.1 uses almost the same words.
The building permit and the trade permits are separate. The 2021 Seattle Residential Code, Section R105.3, says: "Unless otherwise exempted by this or other pertinent codes, separate master use, plumbing, electrical, mechanical and other permits may be required for the above exempted items." Renton's Residential Interior Remodels page (read October 2026) says: "Separate permits are required for electrical, plumbing, mechanical, fire sprinklers and alarms."
Do you need a permit to replace kitchen cabinets and countertops?
Usually not for the cabinets and tops themselves. Five of the eight cities exempt cabinets and countertops by name. Seattle names kitchen cabinets only. Kirkland, Sammamish and Bothell add one condition: existing accessible features must not be altered. Seattle's exemption holds only "provided no changes are made to the building envelope". Bellevue adds: "A plumbing and/or electrical permit may be required if there will be plumbing and/or electrical work."
Issaquah goes further. Its Remodel page (read October 2026) says: "This permit is required for all single family / duplex interior remodels."

Does moving a kitchen sink or adding a gas line need a permit?
Yes, once the pipes move. Bellevue's Work Requiring Permits page (read October 2026) says: "A permit is required to install a new fixture or move an existing fixture that requires installing or modifying existing water lines, drains or vents." It also says: "A permit is required for installing a new gas line or modifying an existing line." Cook tops are among its examples. Sammamish exempts only the "Reinstallation or replacement of prefabricated fixtures that do not involve or require the replacement or rearrangement of valves or pipes" (SMC 16.20.200(5)(c)).
Who issues the plumbing permit depends on the city. Public Health, Seattle and King County says (read October 2026): "PHSKC issues plumbing and gas piping permits, and performs inspections, in the following jurisdictions: Seattle, Clyde Hill, Unincorporated King County." For a house in another King County city, "you will need to get your plumbing and gas piping permits from that city's building department."
In a Shoreline kitchen we rebuilt in 2022, a change order added a repipe of the water lines before the new sink run and laundry nook went in.
Do new kitchen circuits need an electrical permit?
Yes. The Seattle Department of Construction and Inspections Electrical Permit page (read October 2026) says: "You need an electrical permit any time electrical wiring is installed, altered, extended, or connected to any electrical equipment". Bellevue requires a permit "for adding or moving electrical circuits and for changes to the service panel." Kirkland lists "Electrical circuit and service extensions or alterations" as work that needs a permit.
The office varies. Seattle electrical permits come from SDCI. Bothell's Permit Center page (read October 2026) says: "Electrical permits are obtained through Labor and Industries." Renton and Redmond take electrical permit applications themselves.
Our 2024 Renton condo kitchen refresh kept the cabinets, granite and backsplash. The work was a new plank floor, paint and electrical work, and it cost about $35,000.
Does removing a kitchen wall need a permit?
A load-bearing wall needs a permit in every city here, and some cities require one for any wall. Seattle exempts minor repairs or alterations worth $6,000 or less in any six month period, but R105.2 item 1 of the 2021 Seattle Residential Code adds: "Such repairs and alterations shall not include the removal, reduction, alteration or relocation of any loadbearing support." Kirkland lists "Addition, removal or relocation of walls, whether load-bearing or not" as permit work. Redmond answers "All I am doing is constructing or removing a wall, do I need a permit?" with: "Yes, minor remodeling projects such as this are considered to be alterations and therefore a permit is required." Bellevue requires a permit for "a remodel that changes the interior of the house without disturbing structural elements, such as creating new walls".
A load-bearing wall also needs a beam and engineering, as our kitchen pricing guide notes. In a Shoreline kitchen we rebuilt in 2022, a change order added a beam, and a wide opening now joins the kitchen to the living room.
Does a new kitchen window need a permit?
Yes, when the opening is new or larger. A same size replacement often needs none. Bellevue's Work Requiring Permits page (read October 2026) says: "A permit with plan review is required for installing or moving an exterior door, skylight or window, including making an existing window wider. No permit is required for replacements of the same size in the same location." Kirkland lists "Exterior door, window and skylight installations that require a new opening" as permit work. Redmond's Residential Permits page (read October 2026) exempts "Removal and replacement of exterior windows in existing window openings. The size and opening may not be altered and operable opening size may not be decreased."
Who issues kitchen remodel permits in each King County city?
The city the house is in. In Seattle, building and electrical permits come from SDCI and plumbing and gas piping permits from Public Health, Seattle and King County. Kirkland, Sammamish, Bothell and Issaquah take applications through MyBuildingPermit.com, a shared regional portal. Redmond treats building, electrical, mechanical and plumbing as separate submittals. Renton issues electrical, mechanical and plumbing permits online, and its Residential Interior Remodels page (read October 2026) puts a first review decision at typically 2 to 3 weeks. Homes outside city limits go elsewhere: Issaquah's Do I Need a Permit? page (read October 2026) sends Mirrormont to the King County Department of Permitting and Environmental Review and Klahanie to the City of Sammamish.
We prepare and file the permits your layout needs and book each inspection. See Kitchen Remodeling Across the Greater Seattle Area for how a kitchen runs from design to handover. Our city pages: Home Remodeling Contractors in Bellevue, WA and Home Remodeling Contractors in Renton, WA.
How do kitchen permits affect the remodel cost and schedule?
Permits add fees and time before work starts. Our kitchen pricing guide lists permit fees among the items not included in its starting prices. Its timelines start "after design and permits": a small or galley kitchen takes 6 to 10 weeks on site after that step.

Frequently Asked Questions
Does replacing a dishwasher or range need a permit?
Usually not, when it goes in the same spot. Bellevue's Work Requiring Permits page (read October 2026) says: "We do not require a permit for replacing an appliance with a similar appliance in the same location." Kirkland exempts "Like in-kind appliance and fixture replacement (such as dishwashers, ovens, toilets, sinks) in the same location, provided no modifications are made to gas lines, plumbing lines or electrical circuits."
Can I do my own kitchen wiring or plumbing?
Sometimes, with a permit. SDCI's Electrical Permit page says: "Property owners may do their own work when they own and occupy the property they're working on." Renton allows homeowner electrical work if the owner has "resided in the house for at least three (3) years." Public Health, Seattle and King County issues homeowner plumbing permits and says: "The permit issued to a homeowner is an authorization for the homeowner to do the plumbing." All read October 2026.
Do the cabinet exemptions apply near a stream or steep slope?
Not in Kirkland. Its permit page says: "Permit exemptions shall not apply to areas of flood hazard, wetland, steep slope, shoreline or other land use critical areas." Sammamish limits its critical area rule to "activities outside the footprint of an existing legally established structure" (SMC 16.20.200). Check your parcel before work starts.
Does exempt kitchen work still have to meet code?
Yes. Section R105.1 of the 2021 Seattle Residential Code says: "All work shall comply with this code, even where no permit is required." Bothell and Kirkland use similar words: an exemption does not authorize work that violates the code.
