Pasco sits north of the Columbia in Franklin County, the only one of the Tri-Cities outside Benton County, and is among the fastest-growing cities in the state. Its most distinctive rule is one most applicants have never encountered anywhere else.
The Building Division accepts permit applications by email, with the project site address as the subject line and the files attached as PDFs. Files over thirty megabytes go through the city’s online file transfer system instead. Incomplete applications are not processed.
This guide covers work inside the Pasco city limits. Kennewick and Richland are separate cities in Benton County across the river, and Franklin County permits unincorporated areas separately.
Thirty days to collect the permit, or start again. The city’s application carries an acknowledgement that once accepted, the permit application is valid for thirty days — and if the permit is not obtained within thirty days, the permit application and all submitted building and site plans are void. Approval is not the finish line here; collecting and paying for the permit is, and the clock runs on the application rather than on the work.
What requires a building permit in Pasco?
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 Pasco is not whether a code applies, but which edition is in force and what the Pasco Building Division 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 Pasco Building Division 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. Pasco also publishes its review windows plainly, which makes the thirty day rule plannable: residential permits run a five to seven business day review, commercial permits twenty to thirty business days, and commercial projects requiring multiple departmental reviews thirty business days — with the clock beginning once the application and plans are accepted as a complete submittal
Who handles permitting in Pasco?
The Building Division reviews all projects against the building, fire and energy codes, processes permit applications, conducts building and fire inspections on permitted work, and monitors construction to ensure the requirements adopted by the State Building Code Council are met.
| Detail | Information |
|---|---|
| Department | City of Pasco Inspection Services, Building Division |
| Address | 525 North Third Avenue, First Floor, Pasco, WA 99301 |
| Phone | (509) 543-5726 |
| Hours | Monday to Friday, 8:00 a.m. to 5:00 p.m. |
| Submittal | By email with the site address as the subject and files attached as PDFs |
| Large files | Online file transfer system for anything over thirty megabytes |
| On-site plans | The applicant prints and provides the approved plans, minimum page size eleven by seventeen |
| Electrical | All electrical permitted work is handled by the state Labour and Industries programme |
Two obligations sit with the applicant rather than the city. First, printing: it is the applicant’s responsibility to print and make available on site the approved construction plans, at a minimum page size of eleven by seventeen inches, once the building permit has been issued. Second, payment timing: all outstanding fees must be paid in full before the city grants plan approval, and again before the city will issue project inspections.
The application also asks something most Washington cities do not: the applicant selects the dust control method that will be used, from the city’s approved list. In the dry, wind-exposed Columbia Basin that is a live construction requirement rather than a formality.
Permit types
Residential permits
Single family dwelling applications carry a detailed site plan requirement, with the plan on a defined page size and showing the location of all city utilities in the adjoining right of way and on the site, including water valves, meter boxes and irrigation valves. Accessory structures such as pools, sheds and fences included with the permit must show construction details and placement for approval before construction.
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 Pasco Building Division and with the department, because registration lapses are common and an expired registration invalidates the credential the permit relies on.
Commercial permits
Commercial submittals run the longer review windows, and commercial projects requiring development services review carry the thirty business day process. The plan review process begins only once the application and plans are accepted as a complete submittal and processed by city staff, so completeness rather than submission starts the clock.
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 Pasco Building Division requires for the specific building before filing.
Pasco permit costs and fees
Pasco publishes a building permit fee schedule and a building valuation data sheet, with all outstanding fees required in full before plan approval is granted and again before project inspections are issued.
| 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 Pasco Building Division for the schedule in force on your filing date, and confirm the electrical route separately.
Need a real number for a specific Pasco project? Send us the scope, address and valuation and we will identify the edition in force, the local amendments, the electrical route and the fee categories that will apply.
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 Pasco building permit
Site address as the subject line, files attached as PDFs, using the file transfer system for anything over thirty megabytes.
Incomplete applications are not processed, and the review clock starts only on acceptance as a complete submittal.
Five to seven business days residential, twenty to thirty commercial, thirty where multiple departmental reviews apply.
Once accepted, the application is valid for thirty days; miss it and the application and all submitted plans are void.
All outstanding fees must be paid before plan approval and again before inspections are issued.
The applicant provides the approved construction plans on site at a minimum page size of eleven by seventeen.
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 Pasco Building Division 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 Pasco
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 final inspection is requested when the project is complete and the permit is finalled once it passes, so the permit is not closed by the work finishing but by the inspection passing.
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.
Pasco permit search and official resources
Permit records in Washington are split the same way the permits are. Where the Pasco Building Division is the authority for the City of Pasco, 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 collect my permit?
The application dies. The city's application states that once accepted, the permit application is valid for thirty days, and that if the permit is not obtained within thirty days the permit application and all submitted building and site plans are void. Approval is not the same as issuance here.
How do I submit an application?
By email to the permit technicians, with the project site address as the email subject and the files attached in PDF format. Files greater than thirty megabytes go through the city's online file transfer system instead. Incomplete applications will not be processed.
How long will review take?
Residential permits have a five to seven business day review process, commercial permits twenty to thirty business days, and commercial projects requiring multiple reviews thirty business days. The process begins once the application and plans are accepted as a complete submittal.
Who issues my electrical permit?
The state. The city states plainly that all electrical permitted work is handled by the Washington State Department of Labour and Industries. 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.
Do I have to print the approved plans?
Yes. It is the applicant's responsibility to print and make available on site the approved construction plans, at a minimum page size of eleven by seventeen inches, after the building permit has been issued.
