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

Troutdale's permissive posture on STRs (see permit-requirements) extends to occupancy. The city has not enacted an STR-specific guest cap, a per-bedroom formula, a children-counting rule, or a noise-tied occupancy limit; the Troutdale Development Code does not classify STR as a separate use and therefore imposes no use-specific density. The operative occupancy framework is the Oregon Residential Specialty Code (single-family and two-family dwellings) and the Oregon Structural Specialty Code (multi-family), both adopted statewide by the Oregon Building Codes Division and enforced locally by Troutdale's Building Division through Multnomah County's intergovernmental building inspection arrangement. These codes incorporate the standard International Code Council minimum sleeping-room area rule: a sleeping room must contain at least 70 square feet of floor area for one occupant, and rooms occupied by more than one person must provide at least 50 square feet per occupant. The dwelling unit itself must contain at least 120 square feet of living area for the first two occupants (Oregon Residential Specialty Code), with proportional increases for additional occupants under the structural code where applicable. Where an STR operator lists a 'sleeps 12' capacity for a three-bedroom dwelling, the operator should verify that the bedroom-area math under the state code supports that occupancy and that egress, smoke-alarm, and CO-alarm requirements meet code; the city's Building Division can verify capacity through a permit-record check or inspection at the operator's request. Crucially, none of these limits are unique to STRs; they are the same residential occupancy rules that apply to a permanent household. There is no Troutdale ordinance that imposes a tighter ceiling on STR guests than on a permanent occupant. Statements that 'Troutdale caps STR occupancy at ten people' or 'requires a two-per-bedroom rule for vacation rentals' are inaccurate as of May 2026.
