Bellevue, Washington Building Permit Guide

Bellevue is the largest of the eastside cities. Clearing, grading, trees and critical areas reach ordinary residential projects here often, alongside the building code.

Development Services handles building, land use, clearing and grading and critical areas permitting from the Permit Center at City Hall, 450 110th Avenue NE, with applications, plans, fees and inspection requests running through MyBuildingPermit.com, the regional portal used by several eastside jurisdictions.

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

What requires a building permit in Bellevue?

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 Bellevue is not whether a code applies, but which edition is in force and what Bellevue Development Services 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 Bellevue Development Services before work starts.

Local rules worth knowing

The point that catches small projects is the reverse of an exemption: erosion control performance standards must be maintained on site even if the project does not require a clearing and grading permit at all, and the city states that exemption from the permit is not exemption from the city codes requiring sediment and other pollutants to be kept out of the drainage system

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 Bellevue?

Development Services issues building, land use, clearing and grading and critical areas permits, with a dedicated clear and grade desk in the Permit Centre for threshold and submittal questions.

Clearing and grading is a permit family rather than a single instrument. Separate types cover commercial clearing and grading associated with a building permit, non-residential landscape and vegetation work, work in critical areas, and tree removal only on a single-family property where the work is not combined with a building permit and not within the right of way, a critical area, a buffer or a protected vegetation easement. The director may also require single-family building permits and clearing and grading permits to be combined.

A construction stormwater pollution prevention plan is required for all projects meeting the permitting thresholds and must be implemented from initial soil disturbance until final stabilisation. Projects clearing less than 7,000 square feet and grading less than 100 cubic yards may use the short form. Plans must be stamped and signed by a Washington-licensed civil engineer, except for plans prepared for a single-family lot.

In 2025, building permits issued in Bellevue authorized 566 new privately owned housing units, 273 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential work runs alongside the clearing and grading regime, with thresholds at over 1,000 square feet of clearing measured at ground level within a one-year period, or more than 50 cubic yards of grading. Where improvements sit adjacent to a critical area — a stream, floodplain, steep slope, landslide hazard area or wetland — the site plan must show the distance from the improvement to the critical area boundary or setback.

How Washington contractor credentials work

Commercial permits

Commercial clearing and grading covers work associated with a building permit, underground storage tank removal and installation, major changes to non-residential landscaping, walls or rockeries that do not require a building permit, roadway and utility installations, and removal of landmark and significant trees or other permitted activity in critical areas requiring environmental policy review.

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 Bellevue Development Services 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

Bellevue permit costs and fees

Bellevue fees follow the published schedules by permit type, with clearing and grading permits categorised into types by the director and different fees charged for different types. A clearing and grading permit may be issued as a component of a building permit rather than separately.

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 Bellevue Development Services 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 Bellevue 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 Bellevue Development Services before filing.

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

Inspections in Bellevue

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. Erosion and sediment control measures are inspected on site from initial soil disturbance through to final stabilisation, independently of the building inspections.

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.

Bellevue permit search and official resources

Permit records in Washington are split the same way the permits are. Where Bellevue Development Services is the authority for the City of Bellevue, 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

Can I remove a landmark tree myself?

No. The city states that only licensed contractors may remove landmark trees, and that the contractor's name, address, telephone number and current and valid Washington State contractor registration number must be provided before the permit is issued.

What counts as a landmark or significant tree?

A landmark tree is a minimum of 24 inches in diameter at breast height. A significant tree is a minimum of 6 inches at breast height. Both are regulated, and removal in critical areas brings environmental policy review.

Do I need erosion control if I do not need a grading permit?

Yes. Erosion control performance standards must be maintained on site even if the project does not require a clearing and grading permit, and the city states that exemption from the permit is not exemption from the codes requiring sediment and pollutants to be kept out of the drainage system.

When does clearing and grading need a permit?

Thresholds include over 1,000 square feet of clearing measured at ground level within a one-year period, and more than 50 cubic yards of grading. A clearing and grading permit may be issued as a component of a building permit, and the director may require single-family building and clearing permits to be combined.

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, and Bellevue checks the number before issuing. 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.
