Kent sits in the Kent Valley, the industrial and logistics heart of King County, and handles a heavy mix of warehouse, manufacturing and residential work. Its fee structure has two stages and the first one carries a hard deadline.
Most permits need both an intake appointment and formal review. All permits are processed through the city’s permitting portal, with file uploads limited to sixty megabytes and files required to be flattened.
This guide covers work inside the Kent city limits. Unincorporated King County is permitted by the county, and the neighbouring valley cities administer the state code themselves.
Fifteen days, or the application is cancelled. Kent issues a fee invoice at intake and payment is required before permit review can start. All intake fees must be paid within fifteen days or the application will be cancelled. A second invoice for the remaining balance follows once review is complete, and that must be paid before the permit is released. Two invoices, two payments, and one of them on a clock.
What requires a building permit in Kent?
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 amend the state code, but it amends upward from a floor it cannot opt out of. So the question in Kent is not whether a code applies, but which edition is in force and what the Kent Permit Center has added to it.
Permit required
- New buildings, additions, alterations and change of occupancy or use
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Plumbing work under the Uniform Plumbing Code as adopted by the state
- Mechanical and HVAC change-outs, fuel gas work and ventilation
- Work affecting the Washington State Energy Code envelope or systems
- Re-roofing above the exempt scope, demolition, and work in critical areas
Often exempt
- Ordinary repairs and maintenance replacing materials in kind
- Small accessory structures below the code threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture swaps with no alteration to piping
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 Kent Permit Center before work starts.
Your electrical permit almost certainly does not come from the city. For most of Washington, electrical permits are issued and electrical inspections are carried out by the Electrical Program at the Department of Labour and Industries under chapter 296-46B WAC — not by the local building department. A minority of cities run their own electrical programme instead. Establish which applies to the parcel before you assume a single counter handles everything, because the electrical track runs on its own timetable and its own inspector.
The statewide features that catch projects everywhere
Four things shape a Washington filing more than the model code does. First, the edition is set by the state on a three-year cycle and adopted in two groups over a two-year timeline, so the building, residential, mechanical and plumbing parts do not all arrive on the same day. Second, plumbing runs on the Uniform Plumbing Code as adopted by the state, not the International Plumbing Code that most of the country uses. Third, the Washington State Energy Code is its own code under chapter 19.27A RCW rather than the international energy code, and it is among the most demanding in the country. Fourth, growth management and critical areas regulation reach ordinary residential work near wetlands, steep slopes, streams and shorelines far more often than owners expect. Cascadia subduction zone seismic detailing applies statewide. Fire review is not a city function here. Kent is served by the regional fire authority, which publishes its own fee schedule alongside the city’s building and land use schedules — so a project carries fire plan review and fire permit fees set by a separate body, on top of the city fees
Who handles permitting in Kent?
The Permit Center issues building, land use and construction permits for the city, with intake appointments and formal review required for most permit types and multi-department review on commercial projects.

The portal has practical limits that stop submissions before anyone reads them. File uploads are capped at sixty megabytes and files must be flattened, so a large unflattened drawing set simply will not go in. Resubmittals, revisions and deferred submittals all run through the same portal and each requires formal review rather than being handled informally.
Kent also runs a registered plans programme, where an approved house or floor plan is established once and later built on individual lots under site-specific permits. It is common on subdivisions with a small number of models. Registered plans are approved for the duration of a code cycle only, which matters given the state moves the code on a three-year cycle.
Permit types
Residential permits
Residential permits run through the portal, with registered plans available where the same model will be built repeatedly. A certificate of occupancy is not issued for one or two family residences, so the close-out looks different from commercial work. Revisions to an issued permit require formal review rather than a field agreement.
How Washington contractor credentials work
Washington registers contractors rather than licensing them. Under chapter 18.27 RCW every contractor must register with the Department of Labour and Industries, file a continuous surety bond — thirty thousand dollars for a general contractor, fifteen thousand for a specialty contractor — and keep liability insurance on file. Registration runs for two years and carries no continuing education requirement at the base level. Crucially, registration is not a competence test and it does not authorise trade work: electrical work requires certification under chapter 19.28 RCW and plumbing under chapter 18.106 RCW, each with its own examination and its own programme office.
A general registration does not let anyone touch the wiring or the pipes. A registered general contractor must subcontract electrical and plumbing work to appropriately certified trades, and an electrical contractor licence additionally requires at least one certified electrician on staff. Verify the registration is active and the bond and insurance current with the Kent Permit Center and with the department, because registration lapses are common and an expired registration invalidates the credential the permit relies on.
Commercial permits
Commercial and multi-family work — three or more units, or multiple duplexes on a single site — is reviewed by multiple departments at the same time, and certificates of occupancy are issued. Non-residential and multi-family re-roofs go through the minor work permit route, with an engineer’s certification required for a single overlay.
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 Kent Permit Center requires for the specific building before filing.
Kent permit costs and fees
Kent fees come in two stages: an intake invoice payable before review starts, subject to the fifteen day cancellation rule, and an issuance invoice for the remaining balance payable before the permit is released. Fire plan review and fire permit fees are set separately by the regional fire authority.
| Fee component | How it works |
|---|---|
| Building permit | Set by the local jurisdiction, usually on project valuation; the state sets the code, not the fee |
| Plan review | A percentage of the permit fee or a flat charge, set locally |
| Plumbing and mechanical | Separate local permits under the adopted plumbing and mechanical codes |
| Electrical | Usually a state permit fee through the Labour and Industries Electrical Program, not a city fee |
| Energy code | Compliance documentation for the Washington State Energy Code, and review time for it |
| Critical areas and land use | Separate review and fees where wetlands, slopes, streams or shorelines are involved |
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 on most projects it is paid to the state rather than to the city. Ask the Kent Permit Center for the schedule in force on your filing date, and confirm the electrical route separately.

Trade permits and who may pull them
Trade permits are separate from the building permit and, in Washington, are not all issued by the same body. Plumbing and mechanical permits come from the local jurisdiction under the codes the state has adopted. Electrical permits come from the Electrical Program at the Department of Labour and Industries, unless this jurisdiction runs its own. That split is the single most common source of confusion on a Washington project.
Your electrical permit almost certainly does not come from the city. For most of Washington, electrical permits are issued and electrical inspections are carried out by the Electrical Program at the Department of Labour and Industries under chapter 296-46B WAC — not by the local building department. A minority of cities run their own electrical programme instead. Establish which applies to the parcel before you assume a single counter handles everything, because the electrical track runs on its own timetable and its own inspector.

How to apply for a Kent building permit
Most permits need both an intake appointment and formal review; the appointment is not the application.
Review does not start until it is paid, and the application is cancelled if it is not paid within fifteen days.
Files must be flattened and each upload is limited to sixty megabytes.
Fire plan review and fire permit fees are set by the regional fire authority on its own schedule.
Commercial projects are reviewed by several departments at the same time, with correction cycles adding a review period each.
A second invoice for the remaining balance follows review completion and must be paid before the permit is released.
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 the electrical split, where a project waits on a city inspection that was never going to happen because the electrical permit sits with the state. Then edition confusion, because the state adopts in two groups and the parts do not all move together. Build review time into the schedule and confirm the checklist with the Kent Permit Center before filing.
Approvals do not stay live indefinitely. Permit validity periods are set locally on top of the state code, so they differ between neighbouring jurisdictions and cannot be assumed from a previous job. On phased or financed work, confirm the expiry window and keep the permit alive with progress inspections.
Inspections in Kent
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. A certificate of occupancy is not issued for one or two family residences, so residential close-out is completed through the final inspection rather than a certificate.
The point to plan around is that the electrical inspections may be booked with a different body entirely. Where the state Electrical Program holds the electrical permit, its inspector attends on the state’s schedule and the local inspector will not sign off electrical work. Sequencing a cover-up around two independent inspection queues is the practical skill on a Washington job.
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.
Kent permit search and official resources
Permit records in Washington are split the same way the permits are. Where the Kent Permit Center is the authority for the City of Kent, it holds the building, plumbing and mechanical records — but the electrical record for most projects sits with the state Electrical Program instead. If you are buying, refinancing or renovating, check both, because a clean local record does not mean the electrical work was ever permitted.
Confirm the edition, the local amendments and the electrical route. Washington sets a mandatory statewide minimum under chapter 19.27 RCW, but the edition moves in two groups on a three-year cycle and every jurisdiction may amend upward. All three questions have to be answered for the parcel and the filing date.

Frequently asked questions
What happens if I do not pay the intake fee quickly?
The application is cancelled. Kent provides a fee invoice at intake, payment is required before permit review can start, and all intake fees must be paid within fifteen days or the application will be cancelled.
Why is there a second invoice?
Because fees are staged. Once permit review has been completed you receive a new fee invoice with the remaining balance due, and that issuance payment is required before the permit is released.
Why will my plans not upload?
Most often size or format. File uploads are limited to sixty megabytes and files need to be flattened before submission.
Who reviews the fire elements?
The regional fire authority, which serves Kent and publishes its own fee schedule. Fire plan review and fire permit fees sit outside the city building and land use schedules.
Do I get a certificate of occupancy for a house?
No. Certificates of occupancy are not issued for one or two family residences in Kent. Multi-family buildings of three or more units, and commercial buildings, do receive them. Whichever route applies, the contractor behind the permit has to hold a current state credential. Washington registers contractors rather than licensing them. Under chapter 18.27 RCW a contractor registers with the Department of Labour and Industries, files a continuous surety bond of thirty thousand dollars as a general contractor or fifteen thousand 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 itself usually comes from the state rather than the city, because the Electrical Program at Labour and Industries issues electrical permits and carries out electrical inspections for most of Washington under chapter 296-46B WAC.
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 two thousand twenty-one editions took effect on the fifteenth of March, two thousand twenty-four after two delays, and the two thousand twenty-four editions are dated to take effect on the third of May, two thousand twenty-seven. Adoption runs in two groups over a two-year timeline, so the building, residential, mechanical and plumbing parts do not all move on the same day. A city or county may amend upward from the state minimum but cannot opt out of it.
