Ontario ties STR occupancy to bedroom count and California Building Code per-occupant floor area. A common cap is two guests per bedroom plus two additional, with events and parties typically prohibited.
Ontario short-term rental occupancy is limited by the California Building Code minimum floor area per occupant and by the city STR program. A common benchmark used in Ontario STR permits is two adults per legal bedroom plus two additional guests, though the actual cap is set on the permit based on bedroom count, square footage, and parking. California Building Code requires a bedroom to contain at least 70 square feet for one occupant and an additional 50 square feet for each occupant beyond one, plus proper egress windows. Maximum occupancy must be posted inside the unit and disclosed in the listing. Exceeding the posted occupancy is grounds for citation, permit suspension, and insurance problems. Special events, weddings, and parties that push attendance above the posted cap are prohibited at STR properties in Ontario.
