Summary
Seattle's Housing and Building Maintenance Code declares that substandard, deteriorating buildings 'in danger of causing or contributing to the creation of slums or otherwise blighted areas' are hazardous to public health and welfare (SMC 22.200.020.A). SDCI's Director can declare a building unfit for human habitation under SMC 22.208.010 and order it repaired, vacated and closed, or demolished under SMC 22.208.020, with demolition required whenever repair costs exceed 50 percent of replacement value.
It is found and declared that there exist, within The City of Seattle, buildings together with appurtenant structures and premises that are substandard, deteriorating, in danger of causing or contributing to the creation of slums or otherwise blighted areas, and hazardous to the health safety and general welfare of the public.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Municipal Code: Supplement 44 Update 1).
Full Breakdown
SMC 22.208.010 lists the conditions that make a building 'unfit for human habitation or other use,' including structural members too weak to carry imposed loads, inadequate weather protection, inadequate sanitation, defective wiring or heating, inadequate exits, and fire or safety hazards such as accumulated junk or friable asbestos. Once the Director finds those conditions after a notice, hearing, and written complaint process under SMC 22.208.030, SMC 22.208.020 sets the remedy: if the estimated repair cost exceeds 50 percent of the building's replacement value (calculated from the 'Residential Cost Handbook,' Marshall and Swift), the Director orders demolition and removal; if repair costs are 50 percent or less, the Director orders repair, or vacation and closure to the minimum standards in SMC 22.206.200.
A building may also be ordered demolished at owner expense if it was subject to an emergency closure order and suffered two or more unauthorized entries in the prior 12 months with police or fire notice that it endangers the public. If an owner fails to comply, SMC 22.208.100 authorizes the Director to repair, vacate, demolish, or correct the property directly, recovering costs under SMC 22.208.110 by assessing them as a lien against the property, collected with general property taxes and interest under RCW 84.56.020.
Orders may be appealed to the Hearing Examiner within ten days under SMC 22.208.050, and the Hearing Examiner's decision is final absent a land use petition to King County Superior Court within 21 days under SMC 22.208.060.
Violations & Fines
Civil enforcement of the Housing and Building Maintenance Code runs through Seattle Municipal Court under SMC 22.206.280, with cumulative penalties of $150 per day, per housing unit, for the first ten days of noncompliance, rising to $500 per day thereafter until the violation is corrected. Noncompliance with an emergency closure order carries a separate penalty of up to $1,000 per day under subsection 22.206.280.B.
