Washington County
Tigard has not codified a short-term rental-specific occupancy cap (no '10 guests', no '2 per bedroom plus 2'). Occupancy is governed by the Oregon Residential Specialty Code (the Oregon-adopted version of the International Residential Code) and the Oregon Property Maintenance provisions, which use the standard 70 sq. ft. minimum for the first occupant of a sleeping room plus 50 sq. ft. for each additional occupant. The Tigard Community Development Code (Title 18) also limits residential dwellings to Household Living use in most residential base zones, which may constrain the practical character of occupancy.

Hillsboro FAQ
How many short-term rentals can one owner run in Hillsboro?
Under CDC 12.40.230 an owner may operate one Partial-Dwelling STR, which must be the owner's primary residence, plus up to two Full-Dwelling STRs at separate Hillsboro dwellings. Each Full-Dwelling STR requires its own Type II Development Review approval with mailed notice to property owners within 200 feet.
Are guest counts capped per bedroom in a Hillsboro Airbnb?
Hillsboro's CDC 12.40.230 ties occupancy to the bedroom-based parking plan submitted with each STR permit rather than publishing a fixed guests-per-bedroom formula. Multiple bedrooms can be rented at once, but the host must satisfy the parking standard and the Special Use Standards for the declared bedroom count.
Tigard FAQ
How many guests can I host at a Tigard STR?
Tigard has not codified a short-term rental-specific guest cap. The upper bound is set by the Oregon Residential Specialty Code area-per-occupant rules: each sleeping room must provide at least 70 square feet for one occupant and at least 50 additional square feet for each additional sleeping occupant, and each dwelling unit must provide at least 150 square feet for the first occupant and 100 square feet for each additional occupant. There is no codified '2 per bedroom plus 2' figure.
Does Tigard require owner-occupancy of an STR?
No. Owner-occupancy and hosted/unhosted distinctions are not codified in the Tigard Municipal Code or in the Tigard Community Development Code (Title 18). Other Oregon cities (Portland, Bend, Hood River) impose hosted/unhosted rules, but Tigard has not adopted them.
Can my Tigard STR be classified as something other than a single-family dwelling?
Possibly. The Tigard Community Development Code (Title 18) classifies residential uses primarily as Household Living, defined as occupants living as a single housekeeping unit. Transient occupancy that does not fit Household Living may be reclassified as Group Living or a separate commercial lodging use by the Tigard Permit Center based on the base zone, which can affect whether the use is permitted at all. Confirm classification with the Permit Center before operating.
