Operators are generally limited to two units, one of which must be their primary residence, unless they are 'Legacy' operators grandfathered in from before 2017.

What this means for you

To host an Airbnb in Seattle, you need to register for two separate licenses: a general city business license and a special Short-Term Rental (STR) license. You are limited to renting out a maximum of two properties, and for most new hosts, one of those properties must be your primary home. You must also collect a 7% Seattle STR tax in addition to standard sales taxes, though platforms like Airbnb often handle the 7% part for you. Finally, you must include your license number on your public listing to avoid fines.
