Ontario enforces a 72-hour street parking limit under California Vehicle Code 22651(k) and OMC Title 10, and posted street-sweeping days vary by neighborhood with citations typically 55 to 85 dollars.
Ontario adopts California Vehicle Code 22651(k) by reference, allowing police to tow any vehicle that has remained parked on a public street for more than 72 consecutive hours. Street sweeping restrictions are posted block by block, generally once a week between 7 AM and noon, and violations are enforced by Ontario Police parking enforcement. Overnight parking is permitted on most residential streets unless signed otherwise, but vehicles cannot block driveways, fire hydrants (15 feet per CVC 22514), crosswalks, or red-painted curbs. Permit parking districts exist near ONT International Airport and Ontario Mills to prevent long-term airport and shopper overflow; residents in these zones must display a decal. Vehicles over 6 feet in height or 22 feet in length parked on residential streets are further restricted under OMC Chapter 10 commercial vehicle provisions. Parking on unpaved front yards is prohibited under OMC zoning standards. Citations may be contested within 21 days through the Ontario Parking Citation Processing Center.
