How long will the permit take? It depends on what you're building. A deck permit can clear in two months. A 200-unit apartment building can take three years.
Typical Timelines by Project Type
Three things drive the timeline: project complexity, whether design review is required, and SDCI's current backlog.
| Project Type | Typical Timeline | Notes |
|---|
| Simple residential (deck, remodel, ADU) | 2-4 months | Straightforward review, no design review |
| New single-family home | 3-6 months | May require pre-application site visit |
| Small multi-family (under 8 units) | 4-8 months | May avoid design review depending on zone |
| Large multi-family (8+ units) | 12-36 months | Includes design review process |
| Mixed-use development | 12-36 months | Land use + building permit, plus design review |
| Commercial/office | 6-18 months | Depends on size and zoning complexity |
These ranges cover the full process from application to permit issuance. Actual construction time is on top of this.
What Affects Your Timeline
1. Design Review
The single biggest factor. Projects that trigger Design Review (typically 8+ units in lowrise zones) add 6-18 months to the process. The two-meeting sequence, Early Design Guidance followed by a Recommendation meeting, has its own scheduling backlog.
2. Completeness of Submission
Incomplete applications get sent back for corrections, which restarts the review clock. Most applications go through at least one round of corrections.
3. Environmental Review (SEPA)
Larger projects require State Environmental Policy Act (SEPA) review, which adds its own analysis timeline and can be appealed.
4. Appeals
Any design review decision or SEPA determination can be appealed. Appeals add months, sometimes years.
5. SDCI Staffing and Backlog
Review times fluctuate with the department's workload. During construction booms, review times stretch; during slowdowns, they compress.
The Permit Process Step by Step
- Pre-application research. Check zoning and determine what permits are needed.
- Pre-Application Site Visit (PASV). Optional but recommended; a 20-minute coaching session with SDCI staff.
- Submit application. Upload plans and pay initial fees (approximately 75% of total).
- Initial review. SDCI checks for completeness (2-8 weeks depending on complexity).
- Corrections. Address any reviewer comments and resubmit.
- Approval. Plans are approved, and you pay remaining fees.
- Permit issuance. Pick up your permit and begin construction.
How to Track Your Permit Status
Check the Seattle Services Portal
The Seattle Services Portal shows real-time status for any permit by number or address. You can see which review stage you're in and whether corrections are pending.
Monitor on BuildVue
For professionals tracking multiple projects, BuildVue shows permit status across your entire portfolio or area of interest. Set up saved searches with email alerts to get notified when permit statuses change.
Tips for Faster Approvals
- Attend an SDCI coaching session, a free 20-minute video call to answer questions before you submit
- Submit complete applications, since incomplete submittals are the #1 cause of delays
- Start design review early if your project triggers it — DR has its own scheduling backlog on top of everything else
- Hire a permit expediter for complex projects — they know which reviewers handle which project types and how to keep things moving
- Respond to corrections fast — the clock stops while SDCI waits on you
