Federal Way, Washington Building Permit Guide

Federal Way sits between Seattle and Tacoma and runs a four-day permit counter. The submittal route has a built-in lead time before the clock even starts, which makes it one of the easier jurisdictions in the band to underestimate.

The Building Division administers and enforces the building, mechanical, electrical and plumbing codes, covering plan review, permit issuance and inspection. Simple mechanical, electrical and plumbing projects can go through an over-the-counter programme on the regional permitting portal.

This guide covers work inside the Federal Way city limits. Unincorporated King County is permitted by the county, and the neighbouring cities administer the state code themselves.

What requires a building permit in Federal Way?

Washington has a mandatory statewide building code. The codes enumerated in chapter 19.27 RCW, the State Building Code Act, are adopted and amended by the State Building Code Council within the Department of Enterprise Services, and they are required in all cities and counties — local government administers and enforces them rather than deciding whether to have them. A city or county may make the state code stricter but cannot opt out of it, and local changes affecting houses or apartments need State Building Code Council approval. So the question in Federal Way is not whether a code applies, but which edition is in force and what the Federal Way Building Division has added to it.

Local amendments, fee schedules and exempt thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable. An exemption from a building permit is never an exemption from zoning, critical areas review, the energy code or a trade permit. Confirm scope with the Federal Way Building Division before work starts.

Local rules worth knowing

The counter week is four days. Permit applications are accepted and permits are issued between nine and four on Monday, Tuesday, Thursday and Friday, and the Permit Center is closed to the public on Wednesdays — so a week in Federal Way has four working counter days, not five, and a Wednesday deadline is a Tuesday deadline in practice

Washington has a mandatory statewide building code under chapter 19.27 RCW that every city and county enforces and may make stricter; electrical permits come from the Department of Labor and Industries unless the city runs its own programme or Tacoma Power serves the site.

Who handles permitting in Federal Way?

The Building Division administers and enforces the building, mechanical, electrical and plumbing codes for the city, covering plan review, permit issuance and inspection, with a permit centre handling applications four days a week.

The city takes the view that virtually every improvement on a residential or commercial lot requires a permit, with defined residential and commercial exemption lists published separately. Simple mechanical, electrical and plumbing projects can be applied for through the over-the-counter programme on the regional portal rather than going through the upload link route, which is the fastest path available here.

Valuation drives the fee and the applicant supplies it. Fees are calculated on the value of the work being performed, and for remodels, tenant improvements and alterations the valuation must be provided by the applicant based on a legitimate bid or cost estimate reflecting the fair market value of all elements of the project. A copy of the bid may be required for verification, and the building official has authority to assign a valuation.

In 2025, building permits issued in Federal Way authorized 136 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential work follows the state residential provisions with city amendments, and the residential exemption list is published separately from the commercial one. Because the submittal route requires a link the city issues, allow lead time before the review clock can start at all.

How Washington contractor credentials work

Commercial permits

Commercial projects are reviewed by multiple departments at the same time, and correction cycles each add a further review period. Electrical permits use a separate valuation table from all other permit types, so an electrical estimate does not scale the same way as the building estimate.

Registrations, trade certifications and design professionals

Three credential layers appear on Washington projects: the state contractor registration under chapter 18.27 RCW, which nearly everyone doing the work needs; separate state trade certification for electricians and plumbers, each examined and administered by its own programme; and, on commercial and larger residential work, drawings stamped by a Washington-licensed architect or professional engineer. Confirm what the Federal Way Building Division requires for the specific building before filing.

Most Washington contractors register with the Department of Labor and Industries (with a surety bond and insurance) rather than holding a licence; electrical and plumbing contractors also need an L&I contractor licence. Contractor licensing in Washington

Federal Way permit costs and fees

Federal Way calculates all permit fees on the value of the work performed, using one valuation table for electrical work and another for everything else. The applicant provides the valuation from a legitimate bid or cost estimate, and the building official may assign one.

Washington sets the code statewide but leaves the fee schedule local, so two jurisdictions on the same edition can price the same project very differently. The electrical fee is the one that most often surprises people, because it is a separate city permit with its own fee. Ask the Federal Way Building Division for the schedule in force on your filing date, and confirm the electrical route separately.

Fees are set locally, plus a small state permit fee (RCW 19.27.085); the electrical fee goes to whichever body issues the electrical permit. Permit fees in Washington

Trade permits and who may pull them

Plumbing and mechanical permits are local; electrical permits come from the Department of Labor and Industries unless the city runs its own electrical programme or Tacoma Power serves the site. Trade permits in Washington

How to apply for a Federal Way building permit

Review, corrections and what actually causes delay

In Washington the first cause of delay is the energy code, because the state code is its own instrument and more demanding than the international one most designers default to. After that comes critical areas review, which reaches ordinary residential work near wetlands, streams, steep slopes and shorelines and adds its own study and mitigation timeline. Then edition confusion around the switch-over date, when a new state edition takes effect and local amendments change with it. Build review time into the schedule and confirm the checklist with the Federal Way Building Division before filing.

The state code sets a 180-day default for permit validity, but Federal Way may change it, so confirm the expiry on phased or delayed work. Permit validity in Washington

Inspections in Federal Way

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in plumbing and mechanical, insulation and energy code compliance, fire systems on commercial work, and final, with a certificate of occupancy before the building is used. Inspections are requested through the regional portal used for applications, so the same account carries the project through from submittal to close-out.

The city issues its own electrical permits, so electrical inspections are requested from the city rather than from the state.

Do not cover work before the required inspection has been approved. Keep the issued permits — plural — the approved plans and the energy code documentation available on site.

Federal Way permit search and official resources

Permit records in Washington are split the same way the permits are. Where the Federal Way Building Division is the authority for the City of Federal Way, it holds the building, plumbing and mechanical records — and the electrical record too, because the city issues its own electrical permits and carries out its own electrical inspections. If you are buying, refinancing or renovating, check both, because a clean local record does not mean the electrical work was ever permitted.

Frequently asked questions

How do I submit my application?

Electronically, but not directly. All applications requiring review must be submitted electronically, and you first request a Document Upload Link. The city then sets up a file for the project and sends the link. It states that you will not receive the link immediately and that it can take a few days to process.

Is the Permit Center open every day?

No. Permit applications are accepted and permits are issued between nine and four on Monday, Tuesday, Thursday and Friday, and the Permit Center is closed to the public on Wednesdays.

Is there a faster route for small trade work?

Yes. A variety of simple mechanical, electrical and plumbing projects may be applied for through the over-the-counter programme on the regional permitting portal, which avoids the upload link process.

How is my fee calculated?

On the value of the work being performed, using one valuation table for electrical permits and another for all other permits. For remodels, tenant improvements and alterations the applicant provides the valuation from a legitimate bid or cost estimate reflecting fair market value, and a copy may be required for verification.

Which code edition applies?

The state edition as amended by the city. Washington has a mandatory statewide building code. The codes enumerated in chapter 19.27 RCW, the State Building Code Act, are adopted and amended by the State Building Code Council within the Department of Enterprise Services and are required in all cities and counties, so local government administers and enforces them rather than choosing whether to have them. The 2021 editions took effect on the fifteenth of March, 2024 after two delays, and the 2024 editions are dated to take effect on the third of May, 2027. The state adopts a new edition every three years and reviews the codes in two groups, but all of them take effect on the same date (the 2021 codes on 15 March 2024, the 2024 codes on 3 May 2027). A city or county may make the state code stricter but cannot opt out of it; local changes affecting houses or apartments need State Building Code Council approval, and the residential energy code cannot be changed locally.

Who registers my contractor?

The state. Most Washington contractors register rather than hold a licence; electrical and plumbing contractors must also hold an L&I contractor licence. Under chapter 18.27 RCW a contractor registers with the Department of Labor and Industries, files a continuous surety bond of $30,000 as a general contractor or $15,000 as a specialty contractor, and keeps liability insurance on file, renewing every two years. Registration is not a competence test and does not authorise trade work: electrical certification comes under chapter 19.28 RCW and plumbing under chapter 18.106 RCW. The electrical permit comes from the city, which runs its own electrical permits and inspections; elsewhere in Washington the Electrical Program at the Department of Labor and Industries (L&I) usually issues them.
