Is It an Emergency? Note: Life-threatening emergencies and/or after-hours noise complaints should be reported to 9-1-1. We treat emergency conditions differently. The compliance timeframe is very short, usually a few days. If your violation is not corrected, we may close your building and require all occupants to leave, and charge you fines. If you violate a "stop work" order, you may face criminal charges. Emergencies include: No water; No heat; Raw sewage leaks. We may also treat certain construction violations as emergencies, such as those that create a danger to public health and safety. In those cases, we may issue a stop work order, or a hazard correction order for the most serious violations. We may also issue a stop work order for working without a permit. What Types of Notices Are Issued? Citations are like parking tickets: they state a violation and assess a fine right away. Your options are to: Pay the fine; Ask for a hearing to contest the violation; Correct the violation and ask for the fines to be reduced or eliminated at a hearing. Notices of Violation (NOVs) provide a specified amount of time, usually 30 to 60 days, to correct a code violation. You can request a review of the NOV if you disagree with the notice. If the violation is not fixed in time, your fines will accumulate.
Full Breakdown
The most frequently reported code violations in Seattle include: unpermitted construction or alterations (especially ADUs and basement conversions), overgrown weeds and vegetation encroaching on public rights-of-way (SMC 10.52), substandard housing conditions (lack of heat, plumbing failures, pest infestations, mold), illegal land use (operating businesses in residential zones, unauthorized parking lots), work performed beyond the scope of issued permits, and junk or debris accumulation on private property. Seattle is particularly strict about housing code enforcement under SMC Title 22. The Weeds and Vegetation Code (SMC 10.52) requires property owners to prevent vegetation from overgrowing onto sidewalks, streets, and alleys.

SDCI maintains a publicly searchable Code Complaints and Violations database through the Seattle Open Data portal.
