Legal regime

Regulated: two licenses required for all STR operators under Seattle Municipal Code (SMC) Chapter 6.600 (Ordinance 125490, effective January 1, 2019) — a Seattle Business License Tax Certificate and an STR Regulatory Operator License. Most operators are limited to up to two dwelling units (one primary residence and one secondary property); limited exceptions apply for units lawfully operated as STRs before September 30, 2017. Renters are prohibited from obtaining STR operator licenses except for legacy units in the Downtown Urban Core pre-dating September 30, 2017. Prohibited property types include RVs, tents, garages, boats, live-work units, houseboats, and waterfront residences. No annual night cap under Seattle law. Washington State lodging excise tax (retail sales tax plus lodging and convention/trade center taxes) applies per HB 2015; Seattle's city-specific STR tax was repealed in 2018.
