Spokane County is the largest jurisdiction in eastern Washington and permits not only its own unincorporated areas but two small towns as well. Its permit life is unusually generous and its structural design criteria unusually explicit, which together make it one of the more plannable counties in the state.
The Building and Planning Department accepts online applications for unincorporated Spokane County and for the towns of Rockford and Spangle, with a published map showing the service area before an application is started.
This guide covers unincorporated Spokane County and the towns of Rockford and Spangle, which the county also serves. Spokane and Spokane Valley are incorporated and permit separately, and both are covered elsewhere in this series.
Three years, then one extension of 180 days. Building permits automatically expire and become invalid by limitation of time three years from the date of issuance. The director may grant one extension not exceeding 180 days, but the request must be made in writing by the permit holder, received before the expiration date, and must demonstrate just cause. One extension, not several.
What requires a building permit in Spokane County?
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 County is not whether a code applies, but which edition is in force and what Spokane County Building and Planning 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 Spokane County Building and Planning before work starts.

The seismic category has to be earned rather than assumed: portions of unincorporated Spokane County fall within the lower seismic design category, and its provisions may be used only on demonstration by the applicant that the project is located within it — while the basic minimum roof snow load for the county is 30 pounds per square foot, with the director determining a higher figure where local climate and topography make that inadequate
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 County?
Building and Planning issues building permits for unincorporated Spokane County and the two towns it serves, working to the state code as modified in places by the State Building Code Council and by the county code.

Fees now come before review rather than after it. From the middle of 2025 the processing and plan review fees must be paid before the application is routed for review — a project coordinator contacts the applicant by email when the fees are ready, and review only begins once they are paid. On a project with a fixed start date that payment step sits on the critical path.
Addressing is regulated in unusual detail because rural response depends on it. County ordinance requires property addresses to be conspicuously displayed on the building or adjacent to the driveway, with numbers at least 4 inches high, a half inch stroke width and a contrasting background. Buildings more than 100 feet from the public way need the address on a sign or post between three and 6 feet above ground and within 25 feet of the right of way.
Permit types
Residential permits
Residential submittals require foundation plans, floor plans, elevations, cross sections and structural details, with documents saved as individually named files separate from the drawing files. For additions and remodels a key plan for the whole house may be submitted with a partial floor plan covering only the proposed work area.

A general registration does not let anyone touch the wiring or the pipes. A general contractor needs a licensed electrical contractor and a licensed plumbing contractor for that work, or must hold those licences itself, and each electrical contractor must name a master electrician or a certified administrator. Owners may do their own electrical and plumbing work on their own property, with limits for buildings meant for sale or rent. Verify the registration is active and the bond and insurance current with Spokane County Building and Planning and with the department, because registration lapses are common and an expired registration invalidates the credential the permit relies on.
Commercial permits
Commercial plan review typically runs a fortnight to a month depending on project type and complexity, with correction comments generating additional review cycles and commercial projects often taking two or three rounds. Fences over 7 feet require a building permit, and sight-obstructing fences are limited to 3 feet in residential front and flanking street yards.
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 County Building and Planning 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 County permit costs and fees
Spokane County charges processing and plan review fees before routing the application for review, with the balance following. Because electrical permits for unincorporated areas come from the state programme, that cost is invoiced 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 paid to L&I rather than with the building permit. Ask Spokane County Building and Planning for the schedule in force on your filing date, and confirm the electrical route separately.

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 local inspection that was never going to happen because the electrical permit sits with L&I. 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 County Building and Planning before filing.
The state code sets a 180-day default for permit validity, but Spokane County may change it, so confirm the expiry on phased or delayed work. Permit validity in Washington
Inspections in Spokane County
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. Because the address ordinance exists partly for emergency response, a poorly posted address is a practical obstacle to an inspector finding a rural site at all.
The point to plan around is that the electrical inspections may be booked with a different body entirely. Because L&I holds the electrical permit here, 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.
Spokane County permit search and official resources
Permit records in Washington are split the same way the permits are. Where Spokane County Building and Planning is the authority for unincorporated Spokane County, it holds the building, plumbing and mechanical records — while the electrical record sits with the state Department of Labor and Industries (L&I), which issues the electrical permits and carries out the electrical inspections here. 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 long does my Spokane County permit last?
Three years. Building permits automatically expire and become invalid by limitation of time three years from the date of permit issuance, which is the longest permit life in this series.
Can I extend it?
Once. The director is authorised at discretion to grant one extension of time not exceeding 180 days. The request must be made in writing by the permit holder, received by the department before the expiration date, and must demonstrate just cause.
What snow load do I design to?
The basic minimum roof snow load for the county is 30 pounds per square foot except as otherwise provided, and the director determines snow loads in all cases where that figure appears inadequate, based on local climate and topography and the state snow load analysis.
When do I pay?
Before review begins. Processing and plan review fees are payable before the application is routed for review, with a project coordinator contacting the applicant by email when the fees are ready.
Inspections are where schedules slip.
Get a free quote →Which code edition applies?
The state edition as modified in places by the council and by the county code. 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 state, because the Electrical Program at the Department of Labor and Industries (L&I) issues electrical permits and carries out electrical inspections here under chapter 296-46B WAC.
