Spokane, Washington Building Permit Guide

Spokane is the largest city in eastern Washington and the anchor of the Inland Northwest market. Its permitting is well documented, and one of the better-documented things about it is a caution the city publishes about its own tools.

The Development Services Centre sits in City Hall on Spokane Falls Boulevard. Adopted codes are carried in Spokane Municipal Code Title 17F, with permit types set out in Title 17G, chapter 17G.010.

This guide covers work inside the Spokane city limits. Spokane County permits unincorporated areas separately, and Spokane Valley is a distinct city with its own permitting.

What requires a building permit in Spokane?

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

Local rules worth knowing

On the commercial side Spokane runs a Simple Review Process for remodels and tenant improvements, but the qualification test is narrow: a project drops out of the simple route and into an intake meeting with additional requirements if it involves site work, parking lot changes, exterior modifications such as ramps, canopies or additions, or a change in use or occupancy group

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 Spokane?

The Development Services Centre handles building, land use and engineering permitting for the city, with pre-application meetings available to establish project feasibility and set out requirements before the application is prepared.

Commercial applicants have a genuine fork in the road at the start. A commercial remodel or tenant improvement may qualify for the Simple Review Process, which is materially faster. It loses that status if the project involves site work, parking lot changes, exterior modifications such as ramps, canopies or additions, or a change in use or occupancy group — in which case an intake meeting and the fuller new construction requirements apply instead.

There is a second submission most applicants forget. Where the work will be performed at a location where food or beverages will be served or stored, an additional set of plans must go to the Spokane Regional Health District. That is a separate agency on a separate timeline, and it is not triggered by the construction scope but by the eventual use.

In 2025, building permits issued in Spokane authorized 692 new privately owned housing units, 167 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 the city’s amendments in Title 17F applied. Confirm which state code group governs each part of the work at your filing date, since the building, residential, mechanical and plumbing parts move on separate dates under the state adoption cycle.

How Washington contractor credentials work

Commercial permits

Commercial submissions use the commercial application packet, which carries the non-residential energy code form, critical materials forms and a submittal checklist. New construction, additions and change-of-use projects have their own submittal guidesheets and require the intake meeting route rather than simple 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 Spokane 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

Spokane permit costs and fees

Spokane fees are amended annually and published as a dated Development Services Fee Schedule. Where the schedule and an application form or online calculator disagree, the schedule governs, and the city says so explicitly.

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 Spokane 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 Spokane 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 Spokane Development Services before filing.

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

Inspections in Spokane

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. Inspection scheduling runs through the city, including electrical inspections, because the city runs its own electrical programme.

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.

Spokane permit search and official resources

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

Why does my fee estimate not match the invoice?

Probably because you used a calculator. Development Services fees are amended annually, and the city states that the published Development Services Fee Schedule provides the most up-to-date information and supersedes older fees that may still be in the process of being updated on the currently available applications or calculators.

Does my tenant improvement qualify for simple review?

Only if it stays within scope. A commercial remodel or tenant improvement drops out of the Simple Review Process if it involves site work, parking lot changes, exterior modifications such as ramps, canopies or additions, or a change in use or occupancy group, in which case an intake meeting and additional requirements apply.

Which code edition applies here?

The state edition as amended by the city in Title 17F. 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.

Do I need to submit plans anywhere else?

If food or beverages will be served or stored at the location, yes. An additional set of plans goes to the Spokane Regional Health District, which is a separate agency reviewing on its own timeline.

Who registers my contractor?

The state, not the city. 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.

Is Spokane Valley the same jurisdiction?

No. Spokane Valley is a separate incorporated city with its own permitting, its own fee schedule and its own amendments. A Spokane postal address does not settle which of the two holds the parcel.
