Seattle ADU Permit Issued
"Issued" means Seattle has approved the plans and the permit is ready to be picked up — usually after the applicant pays outstanding fees and clears any pre-issuance conditions. Construction can legally begin once the permit is issued, posted on site, and any required pre-construction meeting is done.

What permit issued actually means in Seattle
Issuance is the legal handoff. The city has accepted the plans, the applicant clears the remaining balance (plan review balance, building permit fee, inspection deposits, technology fees, and any impact or connection fees the city collects at issuance), and the permit document is generated.
Pre-issuance conditions are common. Examples: recording a covenant for the ADU on the deed, paying water/sewer connection fees to the appropriate utility, posting a right-of-way bond, or completing a separate side-sewer permit. These do not all live with the building department.
Once issued, the approved plan set and the permit card go on site. Most cities require an inspection card to be visible and accessible to inspectors.
SEATTLE NOTE
Seattle's permit cost depends on size, complexity, valuation, review time, inspection fees, and technology fees — the SDCI fee subtitle (SMC Ch. 22.900) is updated annually and is the authoritative source for the issuance balance.
Why Seattle permit issued hits the high end
- 01How fast the applicant pays the issuance balance after the city emails the invoice
- 02Whether any pre-issuance conditions (covenants, utility fees, bonds) are outstanding
- 03Whether the applicant has been waiting on a separate side-sewer or right-of-way permit
Where the dollars actually come from
- 01Outstanding plan review balance
- 02Building permit fee (often computed from valuation per the state building code fee table)
- 03Inspection deposit / inspection fees
- 04Technology / records / archive fees
- 05Impact fees and utility connection charges (often the largest line item on a new DADU)
Exact dollar amounts vary by project. Use the Seattle fee schedule linked below for the current numbers.
Common homeowner mistakes
Cities publish their fee subtitles. Modeling the issuance invoice in advance prevents project pauses while financing catches up.
Adding a new dwelling unit usually requires a separate side-sewer permit and utility connection fees. These are not part of the building permit fee.
Work before the permit issues and is posted on site can void inspections and trigger stop-work orders.
Permit Issued checklist
These are typical artifacts for an ADU project at this phase in Washington cities. Exact requirements depend on the project and the current Seattle submittal checklist — verify with the city before submitting.
- Issuance invoice paid
- Pre-issuance conditions cleared (covenants, side-sewer permit, utility fees, bonds)
- Approved plan set on site and accessible to inspectors
- Permit card posted in a weather-protected, visible location
- Pre-construction meeting scheduled (if required)
When to call a pro
A Seattle-experienced contractor will line up subs and inspections to start the week of issuance — without that coordination, the project often sits idle for two to three weeks after the permit issues.
Seattle Permit Issued questions
How long does Seattle ADU permit issued take?
For an ADU project in Seattle, WA this phase typically runs ~1 week. Complex sites, missing reports, first-time submittals, or busy permit seasons trend toward the upper end. Resubmittals reset the clock for that round. These ranges are project-level averages — verify the current published timeline with Seattle for your specific project.
What does permit issued cost in Seattle?
Direct Seattle fees for this phase typically run $1,500–$4,000. That excludes designer/consultant time, impact fees, side-sewer / utility connection charges, and inspection fees that may apply separately. The authoritative current numbers live in the Seattle published fee schedule.
Which Seattle department handles permit issued?
SDCI handles this phase; submittals and status live in https://cosaccela.seattle.gov/portal/. See Seattle Department of Construction & Inspections (SDCI): https://www.seattle.gov/sdci/permits/common-projects/accessory-dwelling-units.
What's the most common reason permit issued stalls in Seattle?
Unpaid pre-issuance fees, missing side-sewer or utility connection permits, and pending covenants are the usual stall causes in Seattle. We pre-screen every submittal against the current Seattle checklist before it goes to the city.
Do I need a contractor or designer for Seattle permit issued?
Not legally required for owner-applicants, but in Seattle every ADU permit eventually touches building, land use, fire, and public works review tracks. Contractor coordination is what keeps the schedule honest once the permit is in motion.
How do I check Seattle permit status during permit issued?
Seattle publishes live status inside https://cosaccela.seattle.gov/portal/. The same record carries application data, review comments, fee balances, and (after issuance) inspection results.
