In Seattle, a complaint about construction without a permit led to a Notice of Violation at the same address in 38% of the cases opened in 2024, usually within about three weeks. We counted 422 complaints filed with the Seattle Department of Construction and Inspections (SDCI) that year whose description says the work had no permit. As of October 2026, 200 read “Completed,” 62 read “Closed,” and 160 (38%) still read “Under Investigation.”
We also matched each complaint address to Seattle’s building permit records. Within 12 months of the complaint, 29% of the addresses applied for a building permit. Where a Notice of Violation followed, that rose to 53%; at addresses with no notice, it was 15%. For a buyer, the complaint shows what someone reported, and the permit history shows whether the work was later brought into the permit system.
Where to find construction complaints for a Seattle address
- Complaints and violations: the Seattle Services Portal lists complaint records (numbers ending in “CP”) and enforcement cases for an address, each with its description and current status.
- Permits: the same portal lists building and trade permits. Our Seattle permit search guide explains the search fields and status labels.
- Questions about a case: SDCI’s Violation Complaint Line is (206) 615-0808. SDCI asks for the property address or the case number to give a status, per its How We Respond page.
How SDCI handles a complaint about work without a permit
An inspector checks the reported work. If there is a violation, SDCI issues a warning, a citation or a Notice of Violation, and a notice usually allows 30 to 60 days to correct the problem. The owner can ask for a review of the notice (SDCI, How We Respond).
For construction without a permit, SDCI can issue a stop work order until a permit is obtained. Its Tip 612 on reporting code violations adds that when owners promptly get the permits or make the corrections after being told of a violation, SDCI usually stops short of legal action.
How Seattle’s 2024 unpermitted-construction complaints stand in October 2026
Status is each complaint’s current status in the city’s open data. The last two columns match the complaint address to enforcement cases and building permit applications in the 12 months after the complaint.
| Current complaint status | Complaints | Notice of Violation or citation at the address within 12 months | Building permit applied for within 12 months |
|---|---|---|---|
| Completed | 200 | 66% | 41% |
| Closed | 62 | 26% | 32% |
| Under Investigation | 160 | 8% | 13% |
| All 2024 complaints | 422 | 38% | 29% |
When a notice came, it came fast: the median gap from complaint to the first notice at the address was 18 days, and three in four arrived within 45 days. Of the 161 notices and citations, 116 were construction notices; the rest covered other matters at the same address, such as trees or land use. Today 82 of them read “NOV Issued” and 52 read “Completed.”
“Under Investigation” on a 2024 complaint is the status worth a phone call. Only 8% of those addresses have a notice on file and 13% applied for a permit, so the record alone leaves the outcome open.
Did a building permit follow the complaint?
Within 180 days, 22% of complaint addresses applied for a building permit; within 12 months, 29%, and 27% had a permit issued. Most were addition or alteration permits for a single-family house or duplex (105 of 149). Of those 149 permits, 107 now read “Completed,” 23 “Issued” and 12 “Expired.” Just 4% of the addresses had applied for a permit in the 90 days before the complaint, so in most cases the permit, if any, came after.
Our match uses SDCI building permits. Electrical and other trade permits are separate records, and the portal shows them for the same address. Austin’s records show a similar pattern: 54% of addresses filed a permit within a year when the owner came into compliance, as our analysis of Austin work-without-permit complaints shows. The two cities record outcomes differently, so compare the patterns, not the exact rates.
Checklist: reading a Seattle construction complaint before you buy
- Search the address in the Seattle Services Portal and list every complaint with its open date, description and status.
- For a complaint that still reads “Under Investigation” months later, call (206) 615-0808 with the case number and ask whether an inspection took place and what it found.
- Look for a Notice of Violation at the address after the complaint date. Note the correction date and whether the status moved past “NOV Issued.”
- Compare the complaint description with the permits filed afterward. A complaint about a basement bedroom calls for a permit covering that work, and that permit should read “Completed.” Seattle alteration permits often end as Expired; see our expired permits by project.
- Ask the seller in writing how the complaint was resolved: a permit, removal of the work, or an inspection that found no violation.
For violation records in other cities, see our code violation lookup by address, and for work that never had a permit, our guide to records of unpermitted work.
Los Angeles records the same kind of complaint differently. Our analysis of Los Angeles unpermitted construction complaints follows 7,187 reports from 2022 through LADBS cases and later permits.
Virginia Beach shows a similar pattern: about half of building-work complaints there led to a permit application within a year, in our Virginia Beach unpermitted construction complaints study.
Counts are our calculations from Seattle’s Code Complaints and Violations (complaints opened in 2024 with the Construction type and a description saying the work had no permit) and Building Permits, matched by street address, both pulled October 24, 2026. Address matching misses complaints filed with a descriptive location instead of a street address. More analyses are on our permit data page.
