Pasco, WA Short-Term Rentals: Primary-Residence-Only Rule (2026)

Pasco's prohibition on rentals of fewer than 30 days applies regardless of whether the dwelling is the owner's primary residence, so the city has no owner-occupied or primary-residence carve-out that would let a homeowner run an Airbnb in their own home. The clearest residency-based rule in the code concerns accessory dwelling units. Under the ADU development standards in PMC Chapter 25.161, occupancy of an ADU must be for long-term residential purposes and may not be used for transient occupancy or short-term/vacation rental purposes; persons residing in an ADU must live there for longer than 180 days each calendar year; and either the accessory unit or the primary dwelling must be owner-occupied, with an owner-occupancy agreement recorded on the property title to bind current and future owners. The effect is that an ADU is reserved for long-term living, not short-stay guests, and the property must have an owner living on site in one of the two units. None of this creates a permitted primary-residence short-term rental - it reinforces that even owner-occupied properties cannot offer sub-30-day stays. This entry does not cite a primary-residence STR provision, because Pasco does not authorize short-term rentals at all; the residency requirements that exist are the ADU owner-occupancy and 180-day rules.
