Building Permits in Tacoma

Tacoma requires a building permit for most construction, alteration, and repair work that affects structural, electrical, plumbing, or mechanical systems. Permits are issued by the City of Tacoma Planning & Development Services Department (PDS) — Building & Land Use Services, which administers plan review, inspections, and land use approvals.

Tacoma enforces the Washington State Building Code (Chapter 19.27 RCW), adopted and maintained by the Washington State Building Code Council (SBCC). This code is based on the International Building Code (IBC) and International Residential Code (IRC) with mandatory Washington State amendments — including the Washington State Energy Code (WSEC), which imposes stricter energy efficiency requirements than the base ICC model codes. Because Washington's building code is a statewide mandate under Chapter 19.27 RCW, all jurisdictions including Tacoma must adopt and enforce it without weakening its minimum standards.

Tacoma sits on Commencement Bay (Puget Sound) in Pierce County and is situated in a high seismic hazard region influenced by both the Seattle Fault zone and the Cascadia Subduction Zone. Projects may also be subject to tsunami inundation mapping requirements near the waterfront. These geohazards affect foundation design and structural engineering requirements for permitted work.

When You Need a Permit

You generally need a Tacoma building permit for:

• New construction, additions, and accessory structures (including ADUs — Accessory Dwelling Units)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, and mechanical (HVAC) changes
• Reroofing and window or door openings in exterior walls
• Swimming pools, spas, and retaining walls above a height threshold
• Demolition of any habitable structure
• Changes of use or occupancy classification
• Grading and site work where required by code

Minor cosmetic work (painting, floor coverings, cabinetry without plumbing or electrical changes) is typically exempt. When in doubt, contact PDS at (253) 591-5030 before starting work.

Tacoma Permits Portal — Accela Citizen Access

Tacoma Permits (permits.cityoftacoma.org) is the City of Tacoma's online permitting portal, powered by Accela Citizen Access. It is the primary system for submitting permit applications, uploading plans, paying fees, and scheduling inspections.

Through the Tacoma Permits portal you can:

• Create an account and start a new permit application
• Submit plans for electronic plan review without visiting City Hall
• Track the status of your application and review comments
• Respond to correction notices and resubmit revised documents
• Pay permit fees online
• Schedule and track required construction inspections

For assistance, contact Planning & Development Services at (253) 591-5030 or visit the PDS counter during business hours.

Washington State Building Code — Statewide Mandate

Unlike states where cities may adopt different editions of the I-Codes, Washington State has a unified statewide building code established under Chapter 19.27 RCW. The Washington State Building Code Council (SBCC) adopts and amends the code on a statewide basis. Key features include:

• Washington State Building Code (WSBC) — based on IBC, with WA amendments
• Washington State Residential Code (WSRC) — based on IRC, for one- and two-family dwellings
• Washington State Energy Code (WSEC) — one of the most stringent energy codes in the country, requiring high-performance insulation, fenestration, and mechanical systems
• Washington State Mechanical Code, Plumbing Code, and Fire Code — also adopted statewide

Tacoma enforces the current edition as adopted by the SBCC. Verify the current adopted edition with PDS before preparing construction documents.

Seismic and Geohazard Considerations

Tacoma lies within a high seismic hazard zone. The Cascadia Subduction Zone (CSZ) offshore and the Seattle Fault onshore create significant earthquake risk for the entire Puget Sound region. Practical implications for permit applicants include:

• Seismic design category: Most Tacoma structures fall into Seismic Design Category D or higher, requiring engineered lateral force-resisting systems
• Geotechnical reports: New construction and significant additions on sites with fill, soft soils, or steep slopes typically require a geotechnical investigation by a licensed Washington geotechnical engineer
• Liquefaction and landslide zones: Some Tacoma parcels — particularly near the waterfront and hillside areas — are mapped as susceptible to liquefaction or landslide during earthquakes; additional engineering may be required
• Tsunami inundation: Properties near Commencement Bay and the Puyallup River delta are in mapped tsunami inundation zones; review applicable hazard maps before siting structures

PDS can advise on whether your specific parcel triggers additional geohazard review requirements.

Shoreline Master Program Requirements

Tacoma has significant shoreline along Commencement Bay, the Puyallup River, and other water bodies. Under the Washington Shoreline Management Act (Chapter 90.58 RCW), development within 200 feet of shorelines of statewide significance is subject to Tacoma's Shoreline Master Program (SMP).

If your project is within the SMP shoreline jurisdiction, you may need one of the following before a building permit is issued:

• Shoreline Substantial Development Permit — for most development exceeding a cost threshold
• Shoreline Conditional Use Permit — for uses not outright permitted in the applicable shoreline environment designation
• Shoreline Variance — to deviate from SMP dimensional standards
• Shoreline Exemption Letter — for qualifying minor projects; the exemption must be documented in writing by PDS

Shoreline review is administered by PDS and must be completed or concurrent with building permit review. Do not assume a project near the water is automatically exempt — contact PDS to confirm SMP applicability.

Permit Costs

Tacoma permit fees are established in the official fee schedule published by PDS. Fees typically include:

• Building permit fee — scales with project valuation or square footage
• Plan review fee — a percentage of the building permit fee
• Trade permit fees — separate permits and fees for electrical, plumbing, and mechanical work
• Impact and utility connection fees — for new construction or significant additions
• Shoreline or land use review fees — hourly or flat fees for projects requiring SMP review or land use approval

Do not rely on third-party fee estimates. Check the current fee schedule with PDS or on the Tacoma Permits portal for exact amounts.

Typical Timeline

Correction cycles are typically shorter than the initial review if all comments are fully addressed. Contact PDS at (253) 591-5030 for current workload estimates before planning your project schedule.

The Process

1. Research: Confirm your parcel's zoning, shoreline designation, hazard overlay, and applicable codes — use Tacoma's zoning map and the Tacoma Permits portal
2. Pre-application: For complex projects, schedule a pre-application conference with PDS to identify requirements before preparing full drawings
3. Plans: Prepare construction documents; a licensed Washington architect or structural engineer must stamp documents where required by the Washington State Building Code
4. Geotechnical review: If your site is in a mapped hazard area, obtain a geotechnical report from a licensed Washington geotechnical engineer before submitting plans
5. Shoreline review: If within 200 feet of a shoreline, determine permit or exemption requirements with PDS before or concurrent with building permit submittal
6. Submit via Tacoma Permits: Upload documents and pay initial fees through the Accela portal (permits.cityoftacoma.org)
7. Plan review: PDS reviews for compliance with the Washington State Building Code, energy code, zoning, and applicable overlays
8. Corrections: Respond to review comments and resubmit revised plans through the portal
9. Permit issuance: Pay remaining fees and receive the approved permit
10. Inspections: Schedule required inspections at each construction phase through the portal
11. Final: Pass final inspection and, where applicable, receive a Certificate of Occupancy

Inspections

Typical required inspection stages for residential projects include:

• Site/erosion control — before ground disturbance
• Foundation/footings — before concrete placement
• Underground plumbing and electrical
• Framing — before insulation or interior wall covering
• Rough mechanical, electrical, and plumbing (separate trade inspections)
• Insulation — after installation, before drywall
• Drywall
• Final building and trade inspections

Schedule inspections through the Tacoma Permits portal or by contacting PDS at (253) 591-5030.

Common Reasons for Denial or Corrections

• Plans do not comply with the Washington State Building Code or Washington State Energy Code (WSEC)
• Missing structural calculations, energy compliance documentation, or licensed design-professional stamps
• Zoning conflicts — setbacks, height limits, lot coverage, or use not permitted in the applicable district
• Site is in a geohazard area (liquefaction, landslide, tsunami inundation) without required geotechnical report
• Shoreline Master Program review not completed for projects within 200 feet of a shoreline
• Missing or incomplete seismic design documentation for Seismic Design Category D structures
• Incomplete submittal — missing documents, plans, or fee payments in the Tacoma Permits portal
• Missing utility (water, sewer, stormwater) service or drainage clearances
