Short-term rental permit rules in Ontario, CA — also called Airbnb permits, vacation rental licenses, or STR registration — list the application steps, fees, and operating requirements for hosting.
Ontario requires a Short-Term Rental Permit before any stay under 30 days. Applications are filed through the City Citizen Portal and require proof of primary residence plus a full set of property documents.
The City of Ontario permits short-term rentals (stays under 30 consecutive days) only for operators who hold a valid Short-Term Rental Permit issued by the Planning Division. Applications are submitted electronically through the Citizen Portal and processed under the Ontario Municipal Code STR provisions. Three operator categories qualify: the property owner, the owner's spouse/parent/adult child, or a tenant with written owner authorization. Applications require a site plan, floor plan with bedroom count, proof of primary residence (two documents such as vehicle registration, driver license, voter registration, or recent tax records), a designated 24-hour local contact, and payment of application and annual renewal fees. Permits are not transferable with the property. Operating without a permit is a violation of the Municipal Code and subjects the owner to citation, back taxes, and listing takedowns. Contact Ontario Planning at (909) 395-2000.
