Since July 1, 2023, Ontario requires a displayed permit to park an oversized vehicle (including most RVs, boats, and trailers) on any public street. Permits are limited to 48 hours, no more than two per calendar month, are not issued consecutively, and the vehicle must be parked in front of the owner's own residence.
Ontario's oversized-vehicle program was adopted by Ordinance 3231 (and amended by Ordinance 3261), codified at Ontario Municipal Code Sec. 4-6.1020. The City defines an oversize vehicle for its street-permit program as 'any vehicle, motorized or non-motorized, that exceeds 20 feet in length, or exceeds 80 inches in width or 78 inches in height or that weighs more than 6,000 pounds (gross vehicle weight),' which captures most recreational vehicles, travel trailers, boats on trailers, and large campers. Beginning July 1, 2023, such a vehicle may not be parked on a public street without displaying a valid temporary oversize-vehicle parking permit. Each permit is good for no more than a 48-hour parking period, no more than two permits may be issued per calendar month, permits are not issued on consecutive days, and the oversize vehicle 'must be parked in front of the residence it belongs to' and cannot create a public-safety hazard. Separately, the Off-Street Parking chapter (Sec. 4-13.03) prohibits storing motor homes, campers, boats, or similar equipment on unpaved or landscaped front/street-side yard areas of residential lots.
Parking an oversize vehicle on a public street without a displayed permit, or beyond the 48-hour permit window, is a parking violation subject to citation and tow. Storing an RV or boat on an unpaved or landscaped residential front yard violates OMC Sec. 4-13.03 and is enforced by Community Improvement (Code Enforcement). Permits are obtained through the Business License Division at 303 East B Street, Ontario, CA 91764, (909) 395-2022.
