Ontario distinguishes between hosted and non-hosted STRs and may cap annual rental nights for non-hosted whole-home rentals. Operators must track bookings and retain records for city review.
California cities increasingly distinguish between hosted short-term rentals (owner or operator on-site during the guest stay) and non-hosted whole-home STRs, with tighter rules on the latter. Ontario's STR program may apply an annual night cap to non-hosted whole-home rentals while leaving hosted stays uncapped or counted separately. Caps in comparable Inland Empire cities commonly range between 90 and 180 rental nights per calendar year. Operators must keep accurate booking records, retain platform reports, and be prepared to submit usage summaries to the Planning Division on request. Exceeding an applicable cap can trigger permit suspension, fines, and zoning enforcement. Confirm the current cap for your zoning district and operator type with Ontario Planning at (909) 395-2000 before listing, especially because STR rules in Ontario are updated periodically.
