Tigard, OR Short-Term Rentals: Occupancy Limits (2026)

Because Tigard has not adopted a dedicated short-term rental chapter, there is no city-codified fixed maximum number of overnight guests. Occupancy of any dwelling unit, including one operated as an STR, is controlled by two layers. First, the Oregon Residential Specialty Code (the Oregon-adopted version of the International Residential Code) and the property maintenance provisions in Oregon law incorporate the standard minimum-area-per-occupant rules: every dwelling unit must contain at least 150 square feet of floor area for the first occupant and an additional 100 square feet for each additional occupant; every sleeping room must contain at least 70 square feet of floor area for one occupant, and at least 50 square feet for each additional sleeping occupant. Second, the Tigard Community Development Code (Title 18) defines the use classifications by base zone. Title 18 zones residential dwellings primarily for Household Living, defined functionally as occupants living together as a single housekeeping unit; whether transient occupancy of an entire dwelling counts as Household Living, Group Living, or a separate accessory commercial use is a use-classification determination made by the Tigard Permit Center based on the underlying base zone. There is no codified Tigard STR-specific 'two-per-bedroom-plus-two' guest cap and no codified per-night maximum-guest figure. The state Residential Specialty Code area math sets the upper bound.
