Ontario STR registration requires a Planning-issued permit, Finance TOT certificate, and business license. Annual renewal, a 24-hour contact, and safety inspection items are standard conditions.
To operate a short-term rental legally in Ontario, the owner or authorized operator must complete three parallel registrations. First, a Short-Term Rental Permit from the Planning Division through the City Citizen Portal, which requires site and floor plans, proof of primary residence, owner authorization if the applicant is a tenant, a designated 24-hour local contact, and payment of permit and renewal fees. Second, a Transient Occupancy Tax certificate from Finance, which enables collection and remittance of TOT on every stay under 30 days. Third, a general Ontario business license under the Municipal Code. Permits are issued annually and must be renewed to remain valid. Safety conditions typically include working smoke alarms, carbon monoxide alarms, fire extinguishers, posted emergency information, and compliance with the Ontario noise ordinance. Operating an unregistered STR is a Municipal Code violation and triggers fines, listing takedowns, and back taxes. Contact Ontario Planning at (909) 395-2000 before listing.
