How to apply for a building permit in Tacoma
Step 1: Prepare your materials

Step 2: Apply online
Submit your permit request using Tacoma’s Accela online portal. Here, you have to upload all required documents digitally (DAC Drop in DevHub-style submission for architectural, structural, or civil plans).
Step 3: Plan review
- Intake staff verify completeness: Incomplete ones are quickly returned
- Technical review proceeds: Specialists (planning, structural, mechanical, etc.) examine submissions and issue “checksheets” for necessary corrections

Step 4: Pay final fees
After final approval, a permit invoice is generated within the portal.
Fees here might include:
- Building permit
- Plan review charges
- Impact or utility-related fees
Step 5: Start work and schedule inspections
