Why You Need a Plumbing Permit
A plumbing permit in Spokane is a legal mandate to ensure all work meets the Washington State Building Code (WSBC), specifically the Uniform Plumbing Code (UPC) chapters, as adopted by the state. This requirement is locally enforced by the Spokane Building Services Division under the Spokane Municipal Code (SMC) Title 17. The permit triggers a required review and inspection process by city officials, verifying that all new, altered, or repaired plumbing systems—from a simple fixture replacement to a full backflow prevention assembly—are installed safely, prevent contamination of the water supply, and comply with state and local accessibility standards.
Starting plumbing work without this permit or failing an inspection carries immediate, costly consequences. Based on the enforcement provisions in the SMC and state administrative codes, common penalties include:
- Stop-work orders issued by the city, halting all construction until the permit is secured and work is brought into compliance.
- Daily fines imposed for each day the violation exists, with amounts escalating for repeat offenses.
- Denial of the Certificate of Occupancy or final inspection, legally preventing you from opening or using the space.
- Required demolition of non-compliant work at your expense, so inspectors can verify underlying compliance before re-installation.
- Voided insurance claims or lease defaults, as most policies and commercial leases require all work to be permitted and code-compliant.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Washington state has adopted the 2024 editions of the Uniform Plumbing Code (UPC) and International Building Code (IBC), which Spokane enforces—applicants must ensure their plans and specifications comply with these updated standards.
Who Needs a Plumbing Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required for installing or altering plumbing for kitchen sinks, dishwashers, mop sinks, and restroom fixtures per Spokane Municipal Code (SMC) Title 21, which governs new commercial construction and tenant improvements. |
| Bar / Nightclub | Required | Required for any plumbing work, including installing bar sinks, ice makers, drain lines, and restroom facilities under SMC Title 21, as these are considered alterations to the building's plumbing system. |
| Food Truck | Not Required | Generally exempt for the vehicle's plumbing system, which is regulated under Washington State Department of Health mobile food unit permits; however, a permit is required if connecting to a fixed utility source at a commissary or base of operations. |
| Coffee Shop / Café | Required | Required for installing plumbing for espresso machines, prep sinks, and restrooms, as these constitute new plumbing fixtures under the Spokane Building and Plumbing Code (adopts International Plumbing Code). |

27 of 33 auto-filledJob Site Address
textEnter the full, physical address of the restaurant where the plumbing work will be performed—this must match the location on your lease and business license.
COMMON MISTAKE: Using a P.O. Box, mailing address, or corporate office location instead of the physical job site, which triggers an immediate rejection.
Property Owner Name
textEnter the legal name of the individual or entity that holds title to the property, as it appears on the deed or county tax records.
COMMON MISTAKE: Entering the business name, LLC name, or tenant's name if they are not the legal property owner, which invalidates the application.

textProvide a direct, working phone number for the property owner where they can be reached during business hours by Spokane Building & Planning staff.
COMMON MISTAKE: Providing a disconnected number, a tenant's phone, or a number with an out-of-state area code without explanation, which delays verification.
Property Owner Email
textEnter a valid, monitored email address for the property owner to receive digital correspondence and permit status updates from the city.
COMMON MISTAKE: Using an incorrect or defunct email address, which causes important inspection notices or approval documents to bounce.
Business Different from Owner?
checkboxCheck this box only if the business operating at the address (e.g., your restaurant) is a different legal entity from the property owner listed above.
COMMON MISTAKE: Failing to check the box when the business and owner are different, which omits required tenant information and stalls review.
Business Name
textIf 'Business Different from Owner?' is checked, enter the exact legal name of your restaurant business as registered with the Washington Secretary of State.
COMMON MISTAKE: Using a 'Doing Business As' (DBA) name instead of the registered legal entity name, which creates a mismatch with state records.
Business Contact Person
textEnter the full name of the primary point of contact for the business (e.g., general manager, owner-operator) who will coordinate with inspectors.
COMMON MISTAKE: Listing a contractor or plumber instead of an authorized business representative, which violates Spokane's permit holder of record rules.

textProvide a direct phone number for the business contact person, ideally a mobile number, to schedule required plumbing inspections.
Business Email
textEnter a valid email address for the business contact to receive inspection results and permit documents from Spokane's permit portal.

textEnter the official building use code from Spokane's zoning ordinance (e.g., 'A-3 Assembly' for restaurants, 'M' for Mercantile); reference your Certificate of Occupancy.
COMMON MISTAKE: Guessing or using generic terms like 'restaurant' instead of the specific code, which triggers a plan review for use verification.

Top 5 Plumbing Permit Mistakes
1. Selecting the Wrong Permit Type
Spokane's permit portal offers several plumbing permit options (new construction, remodel, fixture replacement, gas line). Choosing the wrong one triggers an automatic rejection, requiring a complete re-application. Based on ApronPrep's analysis of Plumbing Permit applications in Spokane, this mistake adds 3-5 business days to your timeline. Avoid it by verifying your project scope matches the permit description; for example, installing a new water heater for an existing sink requires a 'Fixture/Appliance Replacement' permit, not a 'Remodel' permit.
2. Using Inaccurate Contractor or License Information
Entering incomplete or incorrect contractor names, state license numbers (like a Washington State Unified Business Identifier - UBI), or expiration dates is a high-rejection risk field. The Spokane Building Division cross-checks this data in real-time against state databases. A mismatch results in an immediate hold. To avoid this, have your licensed plumber's UBI number and their full business name (exactly as registered with the state) ready before you start the application.
3. Submitting Incomplete Site Plan Details
The application requires a detailed site plan showing the location of all new and existing plumbing work relative to property lines and structures. A common mistake is submitting a vague sketch instead of a scaled drawing with clear dimensions. This omission leads to a 'plan review correction' notice, which can delay approval by 1-2 weeks. Ensure your plan includes all fixtures, pipe routes, and distances to critical features like the sewer main cleanout.

Step 1: Determine plumbing work scope - identify all fixtures to be installed, moved, replaced, or roughed-in (kitchen sinks, grease traps, floor drains, backflow preventers, etc.)
Walk your restaurant space with your plumber to mark every planned fixture on a floor plan. The City of Spokane requires separate permits for each type of work (new, alter, repair), so misidentifying the scope is a common cause for reapplication. Duration: 1-2 hours.
Step 2: Obtain contractor license number and contact information from licensed plumbing contractor performing the work
Verify your plumber holds an active Washington State Plumber UBI# and is bonded and insured for Spokane. The city will reject applications from unlicensed contractors. Have their license certificate and insurance declaration page ready to upload. Duration: 1 day.
Step 3: Complete the Plumbing Permit Application form with job site address, property owner/business information, contractor details, and building use classification (Commercial for restaurant)
Use the Spokane Unified Permit Application form (PDF). For building use, select 'Commercial' and specify 'Food Service Establishment.' ApronPrep auto-fills property and business details from your profile. Incorrect owner/contractor roles cause immediate rejection. Duration: 15 minutes.

See All RequirementsProcessing time varies significantly based on project complexity, the completeness of your application, and City review workloads. For small-scale residential repairs, approval can take 1–2 weeks, while extensive commercial work requiring plan reviews may take 4 weeks or longer. To avoid delays, ensure your submitted plans comply with the 2021 Uniform Plumbing Code, as adopted by Spokane, and include any required supporting documents like a Backflow Prevention Device Certification if applicable.
Government filing fees for a plumbing permit in Spokane are based on the valuation of the work, starting from $0 to $11 for minimal projects, per the Spokane Planning & Development Services fee schedule. More complex installations have higher fees, calculated as a percentage of the total job cost. Contact Spokane's Permit Center directly to confirm the exact fee for your project scope, as this does not include potential charges for inspections or related permits like a Building Permit. Not legal advice.
No. Plumbing permits issued by the City of Spokane are specific to the property and project described in the original application and are not transferable between locations. If work moves to a new site, you must apply for a new permit. Starting a new application ensures the plans are reviewed for compliance with the specific zoning and plumbing infrastructure at the new address.
Plumbing permits themselves are not recurring licenses; they are single-use authorizations for a specific construction project. However, if work is not started within 180 days of issuance, or is abandoned for more than 180 days, the permit expires and you must apply for a new one. Ongoing operational compliance may involve other annual requirements, like maintaining a valid City Business License/Registration.
A City of Spokane plumbing inspector will visit your site to verify the installed work matches the approved plans and complies with code. They check for proper materials, venting, drainage, fixture installation, and backflow prevention. You or your licensed plumber must be present to provide access; failing an inspection typically requires corrections and a re-inspection fee, adding 3–5 business days to your project timeline.
