Why You Need a Plumbing Permit
A Plumbing Permit in Tacoma is mandated by the Washington State Building Code (WSBC), specifically chapters covering plumbing systems, which is locally administered and enforced by the City of Tacoma's Permit Services Department. The primary legal authority is the Tacoma Municipal Code (TMC) Title 2, Chapter 02.05, which establishes the city's permitting authority, and the specific technical requirements are found in the Washington State Plumbing Code (WSPC). This code adoption ensures that all plumbing installations—whether for a new restaurant sink, bathroom fixtures, or gas line—meet state standards for safety, sanitation, and water conservation, protecting public health and property.
Installing plumbing without this permit carries significant, immediate consequences. Based on the enforcement protocols of Tacoma Permit Services, the typical penalties include:
- Stop-work orders: The city can legally halt all construction activity on your site until the violation is corrected, freezing your opening timeline.
- Fines and fees: You will be subject to double permit fees (standard practice for work commenced without a permit) and possible daily penalties until compliance is achieved.
- Certificate of Occupancy denial: The city will not issue the final CofO required to legally open your business to the public.
- Required demolition City inspectors can mandate the removal of non-compliant work at your expense for re-inspection, adding substantial unplanned costs.
- Insurance and lease implications Unpermitted work typically voids commercial property insurance clauses and constitutes a breach of most commercial leases, risking eviction or loss of coverage for any related damages.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of the 2024 code cycle, Tacoma has fully adopted the 2021 versions of the Washington State Building Code suite, including the Plumbing Code (WSPC), meaning all permit applications must demonstrate compliance with these updated technical standards.

28 of 34 auto-filledBusiness Legal Name
textEnter your restaurant's official legal name exactly as it appears on your Washington State Business License, Articles of Incorporation, or IRS SS-4 confirmation letter; do not use a DBA or trade name unless it's your registered legal entity.
COMMON MISTAKE: Using the restaurant's operating name (DBA) instead of the official legal entity name registered with the state, which causes rejections because the permit must be issued to the legal owner of the work.
Business License Number
textProvide your active Washington State Unified Business Identifier (UBI) number, which is a 9-digit code starting with '60' or '80', found on your state business license or tax registration certificate.
COMMON MISTAKE: Entering a city of Tacoma business license number instead of the state UBI, or leaving the field blank if the business is new, which requires a 'Pending Application' note.
Business License (Copy)
checkboxCheck this box to confirm you are attaching a clear, legible copy of your Washington State Business License showing the UBI number, business name, and active status.
COMMON MISTAKE: Checking the box but failing to attach the document, or attaching an expired or city-only license, which stops review until the correct state license is provided.
Property Street Address
textEnter the full, official street address of the restaurant property where plumbing work will occur, including suite or unit number if applicable; use the address from your lease, deed, or Pierce County parcel report.
COMMON MISTAKE: Using a mailing address, P.O. Box, or an address that doesn't match the legal property description in city records, which causes planning delays.
City
textEnter 'Tacoma' as the city for the property; this must match the jurisdiction of the Tacoma-Pierce County Health Department and City of Tacoma Planning Department.
COMMON MISTAKE: Entering a neighboring city like 'Lakewood' or 'Fife' if the property is near a border, which routes the application to the wrong jurisdiction and adds weeks to the timeline.
State
textEnter 'WA' or 'Washington' for the state; this field is typically auto-filled by ApronPrep from your property profile to ensure consistency.
COMMON MISTAKE: Leaving blank or using a two-letter abbreviation for a different state, which is a clerical error but requires correction.
ZIP Code
textProvide the correct 5-digit ZIP code for the property address; verify using the USPS ZIP Code Lookup tool to ensure it matches the city of Tacoma's zoning records.
COMMON MISTAKE: Using the ZIP code for a nearby post office that serves the area but is technically a different city, which can trigger a jurisdiction review.
Property Ownership Status
textState your relationship to the property: enter 'Owner,' 'Tenant,' or 'Authorized Agent'; if you are a tenant, you must also provide a signed owner authorization letter.
COMMON MISTAKE: A tenant incorrectly selecting 'Owner' or failing to provide the required owner authorization, which is a common cause for immediate rejection per Tacoma Municipal Code 2.02.040.
Property Ownership Documentation
checkboxCheck this box to confirm you are attaching proof of ownership, such as a recorded deed, title report, or most recent property tax statement, if you are the property owner.
COMMON MISTAKE: Owners checking the box but attaching a lease agreement or mortgage statement instead of a deed, which does not prove legal ownership and halts the permit.
Lease Agreement
checkboxIf you are a tenant, check this box to confirm you are attaching the full, signed lease agreement showing the restaurant's legal name, address, lease term, and owner/landlord signature.
COMMON MISTAKE: Tenants attaching only the first page or a summary of the lease, which lacks the necessary signatures and legal descriptions required by the Tacoma Planning Department.

Top 5 Plumbing Permit Mistakes
1. Mislabeling Fixture Counts
Incorrectly tallying the number of sinks, toilets, or water heaters leads to immediate plan review rejection, as it changes the scope of work and fee calculation. For example, listing two toilets when your renovation involves three will require a complete resubmission after a reviewer catches the discrepancy. Count every fixture on your plans carefully, including new and existing units being replaced.
2. Using Generic Descriptions Instead of Fixture Make/Model
Entering 'sink' or 'water heater' without the manufacturer name and model number (e.g., 'KOHLER K-3814-0' or 'Rheem XG40T06EC36U1') will cause a delay. Tacoma requires specific fixtures to be listed to verify compliance with approved plumbing standards and water efficiency ratings. Always pull the exact make and model from the product specification sheet before you fill out the application.
3. Submitting Incomplete or Unscaled Drawings
Providing hand-drawn sketches or floor plans without a proper scale and clear fixture locations is the top cause of plan review delays. Tacoma inspectors need a 1/4" = 1' scale drawing showing all plumbing runs, vent stacks, and fixture placements relative to walls. Missing this detail adds 1–2 weeks while the city requests corrected plans from your contractor or designer.

Timeline: Varies
Step 1: Contact Tacoma-Pierce County Health Department or City of Tacoma Building & Land Development Services to determine if your plumbing work requires a permit
Call or email the Tacoma-Pierce County Health Department (TPCHD) Environmental Health division or the City of Tacoma Building & Land Use Services counter. You must confirm your project scope triggers permit requirements under the Washington State Plumbing Code (WAC 51-46) and Tacoma Municipal Code Title 2 — common triggers include installing a new commercial kitchen sink, grease interceptor, or water heater. Having your floor plan and equipment list ready speeds up this inquiry. Duration: 1-2 business days to get a definitive answer.
Step 2: Obtain the Plumbing Permit application form from tacoma.gov or the local building department
Download the most current 'Plumbing Permit Application' (Form BLD-001) from the City of Tacoma Permits & Inspections website. As of 2026, Tacoma also uses the MyTacoma online portal for digital applications. Confirm you have the correct version; using an outdated form is a top reason for immediate rejection. Print two copies if submitting in person. Duration: 30 minutes to locate and download.
Step 3: Complete the application with detailed plans showing kitchen sink installation, grease trap location, sizing, and connections to municipal sewer system
Fill out all applicant, contractor, and project details. You'll need your contractor's state license number (if applicable), parcel number, and detailed work description. For restaurants, sketches must clearly show the proposed fixture locations, pipe sizes, and the grease interceptor's rated capacity in gallons per minute (GPM) with its connection point to the city sewer main. Missing interceptor specs is the #1 cause of plan review delays. Duration: 2-4 hours for manual completion; ApronPrep auto-fills 70% of fields.

See All RequirementsProcessing time varies significantly based on project complexity. For simple re-pipes or fixture replacements, the City of Tacoma's Permits & Inspection Services Division may review within a few business days. For major commercial projects requiring plan review, contact the department to confirm current timelines, which can extend to several weeks based on their posted guidance.
The government filing fee for a standard plumbing permit application in Tacoma is $0. This base fee is listed on the city's fee schedule. However, total project costs are calculated during the plan review phase based on job valuation, and you will also need a separate Building Permit for most structural work, which carries its own fees. Not legal advice — verify final costs with Tacoma Permits & Inspection Services.
No, plumbing permits are not transferable between locations or property owners. Permits are issued for a specific scope of work at a specific address. If you move or sell the business, the new owner must apply for new permits. This is standard for trade permits to ensure the city's inspection records and property files remain accurate per Tacoma's municipal code.
Plumbing permits themselves are not renewable annual licenses; they are one-time approvals for a specific project. However, your overall business must maintain other recurring licenses. For instance, all businesses operating in Tacoma must annually renew their City Business License/Registration. The plumbing work must also pass final inspection before the permit is considered closed.
A city inspector visits your site to verify the installed plumbing matches the approved plans and meets the Uniform Plumbing Code (UPC) standards adopted by Tacoma. They check for proper materials, venting, drainage, water supply, and fixture installations. Common inspection points include testing for leaks and verifying backflow prevention devices, which themselves require a separate Backflow Prevention Device Certification.
