Remodeling permits, Seattle
Do You Need a Permit to Remodel in Seattle?
A remodel in Seattle needs a building permit unless the 2021 Seattle Residential Code exempts it. Exempt work includes painting and kitchen cabinets with no change to the building envelope, and minor work worth $6,000 or less in six months. Any loadbearing change needs one. You apply to SDCI online, and trade work needs its own permit.
Every rule below is quoted from the adopted code or from city and county permit pages, read in October 2026. To have one team design, permit and build your remodel, Book a Consultation.
Which remodeling work needs a permit in Seattle, inside and out?
Almost all interior and exterior remodeling work. Section R105.1 of the 2021 Seattle Residential Code (PDF page 6, read October 2026) says "a building permit shall be obtained from the building official for each building or structure prior to erecting, constructing, enlarging, altering, repairing, moving, improving, removing, changing the occupancy of, or demolishing such building or structure". It adds: "All work shall comply with this code, even where no permit is required." SDCI lists the 2021 edition as current, and its code adoption page (read October 2026) expects the 2024 codes "no sooner than May of 2027".
The trades have their own permits. SDCI's 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". Public Health, Seattle and King County says on its plumbing permits page (read October 2026): "Whenever you are going to install, relocate, or change a plumbing or gas piping system, Seattle and King County codes require that you obtain a permit."

What remodeling work is exempt from a permit in Seattle?
Section R105.2 (PDF page 7) lists the work that needs no building permit. Its lead sentence warns that exemption "does not authorize any work to be done in any manner in violation of this code or any other laws or ordinances of the City." These are the items a homeowner meets most often, word for word.
| Item | Exempt work, as the code words it |
|---|---|
| 1. Minor work | "Minor repairs or alterations if the value of construction, as determined by the building official, is $6,000 or less in any six month period. Such repairs and alterations shall not include the removal, reduction, alteration or relocation of any loadbearing support. Egress, light, ventilation and fire-resistance shall not be reduced without a permit." |
| 2. Finishes | "Minor work including the following, provided no changes are made to the building envelope: patio and concrete slabs on grade; painting or cleaning a building; repointing a chimney; installing kitchen cabinets, paneling or other surface finishes over existing wall and ceiling systems; insulating existing buildings; abatement of hazardous materials; and in-kind or similar replacement of or repair of deteriorated members of a structure." |
| 4. Fences | "Fences not over 8 feet high that do not have masonry or concrete elements above 6 feet." |
| 7. Low platforms | "Platforms, walks and driveways not more than 18 inches above grade and not over any basement or story below." |
| 12. Roofs | "Roof replacement if no changes are made to the building envelope other than adding or replacing insulation, and the work is equivalent to or better than the existing structure. Permits are required for structural changes and replacement of sheathing of any size." |

Does retiling or new flooring need a permit in Seattle?
Often, yes. R105.2 does not exempt floor coverings or tile by name. Item 2 names "surface finishes over existing wall and ceiling systems" only, and only "provided no changes are made to the building envelope". A floor or shower retile can fit item 1 only if its value is $6,000 or less in six months and it touches no loadbearing support. Ask SDCI before you start.
Neither exemption covers the trades. Section R105.3 says "separate master use, plumbing, electrical, mechanical and other permits may be required for the above exempted items." A new shower valve, a moved drain or a new circuit for a heated floor is trade permit work.
Does the $6,000 limit cover a kitchen or bathroom remodel?
Rarely. SDCI's Do You Need a Permit? page (read October 2026) says "The $6,000 limit is based on fair market value of labor and parts, even if you do the work yourself." Our own pricing guides, updated October 2026, start a kitchen refresh at $35,000+ and a small bathroom at $25,000+.
Our Seattle jobs show the same scale. Our attic bathroom in Seattle, where the old tub became a walk-in shower in 2021, cost about $30,000. Our finished basement in Seattle, completed in July 2024 with new closets and one plank floor through the level, cost about $120,000.

How do you get a remodeling permit in Seattle?
You apply online through the Seattle Services Portal, and the permit type follows the size of the job. SDCI's Addition or Alteration page (read October 2026) says "You need a construction permit to remodel or add onto your building". Simple work may qualify for a Subject-to-Field-Inspection (STFI) permit. SDCI's STFI page (read October 2026) names "remodeling a portion of your house" as a common example. Larger or structural work goes through plan review.
Section R105.5 sets what the application holds. It must give the contractor's business name, address, phone and "current contractor registration number (required if contractor has been selected)", and it must be "signed by the owner of the property or building, or the owner's authorized agent".
Section R105.6.1 requires plans by "an architect or structural engineer licensed to practice under the laws of the State of Washington", but Exception 1.1 lets the building official waive that for "Detached one- and two-family dwellings." SDCI's House Additions and Remodels page (read October 2026) says house drawings "rarely require a professional stamp".
How long does a Seattle remodeling permit take?
From 48 hours for a simple permit to months with plan review. SDCI's permit cost page (read October 2026) says it issues "some simple building permits with minimal review within 48 hours" of the application. For plan review, the Addition or Alteration page says: "We try to finish our initial review of simple permit applications in 2-3 weeks and complex permits in 8 weeks."
SDCI's Construction Permit Performance page (read October 2026) sets a goal of 30 days for a single family addition or alteration. It reports 64 days at the 75th percentile, counting only days in City control, and says the total an applicant sees "is roughly twice the calendar days in City control."
A permit then runs for a set time. Section R105.13 says "Authority to do the work authorized by a permit expires 18 months from the date of issuance." For the whole schedule, design and construction included, read How long does a remodel take in Seattle?
How much does a remodeling permit cost in Seattle?
It depends on the value of the work. SDCI's How Much Will Your Permit Cost? page (read October 2026) lists six factors: the size and complexity of the project, the value of the work, additional permits, review time, inspection fees and technology fees. It publishes a 2026 Fee Subtitle and a 2026 Fee Estimator for an exact figure.
Timing differs by permit. With plan review, "You must pay 75 percent of the total plan review and permit fees when your permit application is accepted." An STFI permit pays "40% of the plan review fee calculated in the Fee Estimator spreadsheet", with all fees due when the permit is issued.
Permit fees are not in our published prices. Our kitchen and bathroom pricing guides, updated October 2026, list "Permit fees" under "Not included in starting prices".
Who pulls the remodeling permit, you or the contractor?
On our jobs, we manage it. Our FAQ says "One team designs, permits and builds the project", and that we "manage construction, including permits, the budget and updates." See General Contractor Across the Greater Seattle Area for every service, and Home Remodeling Contractors in Seattle, WA for our work in the city.
The code names the holder. Section R105.8.1 says "When the permit is issued, the applicant or the applicant's authorized agent becomes the permit holder." Owners may also do some work themselves. SDCI's Electrical Permit page says "Property owners may do their own work when they own and occupy the property they're working on."
What happens if you remodel without a permit in Seattle?
A stop work order, a daily fine and extra fees. Section R103.3 (PDF page 4) lets the building official "issue a stop work order whenever any work is being done contrary to the provisions of this code". Section R103.5 sets the fine: "Any person violating or failing to comply with the provisions of this code shall be subject to a cumulative civil penalty in an amount not to exceed $500 per day for each violation from the date the violation occurs or begins until compliance is achieved." Section R103.7 (PDF page 5) says "civil actions to enforce Seattle Municipal Code (SMC) Title 22 must be brought exclusively in Seattle Municipal Court".
SDCI's Construction Without a Permit page (read October 2026) says the same: "If you build without a permit, you may be fined up to $500 per day." It adds that skipping the final inspection can bring a fine or other enforcement.
Starting work before the permit can add a fee. Section R106.11 (PDF page 15) says that for work started before a permit, "a special investigation fee may be assessed in accordance with the Fee Subtitle."
Frequently Asked Questions
Do I have to bring my whole house up to code when I remodel?
No. SDCI's House Additions and Remodels page (read October 2026) says: "You do not need to upgrade existing portions of your house that are not being remodeled to the current codes." The new work must meet current code, and any structural impact must be shown in the permit design.
Can I ask SDCI whether my project needs a permit?
Yes. SDCI's Construction Without a Permit page (read October 2026) offers a 20 minute coaching session with a permit specialist through the SDCI Services page. Bring the address, a sketch of the existing structures with distances to the property lines, and a description of your project.
Does a permitted remodel need a final inspection?
Yes. Section R106.6 of the 2021 Seattle Residential Code says "There shall be a final inspection and approval of all buildings when they are completed and ready for occupancy." Each earlier inspection must be approved before work moves past that point.
Are the rules the same in Bellevue and other Eastside cities?
No. Bellevue issues its own permits and words its exemptions differently. Bellevue's Work Requiring Permits page (read October 2026), for example, needs no permit for "replacing a fixture with a similar fixture in the same location, such as wash basins, toilets, bidets and laundry tubs," and says "Showers and bathtubs require permits." Our bathroom and kitchen permit guides compare eight King County cities.
