Rialto, CA Short-Term Rentals: Parking Rules (2026)

Title 18 (Zoning) parking minimums are applied as part of the original building permit and are not increased for STR use because STR is not a defined zoning use. The standard R-1 single-family requirement is 2 covered off-street spaces; multi-family and mixed-use zones have separate schedules. Title 10 (Vehicles and Traffic) authorizes Rialto Police to enforce: (1) the 72-hour stored-vehicle rule under Cal. Veh. Code §22651(k), (2) posted overnight or street-sweeping restrictions, (3) prohibitions on parking on unpaved surfaces, in front yards, or blocking sidewalks (also enforceable under Title 8 nuisance provisions). Heavy commercial truck parking is regulated separately because of Rialto's freight/logistics corridor — Title 10 contains truck-route restrictions that apply to oversized guest vehicles. RVs and trailers cannot be parked on residential streets between midnight and 5 a.m. under California Vehicle Code §22651(o) authority as applied locally. The Rialto Municipal Airport (L67) AIA overlay in Title 18 restricts certain uses and parking configurations near the runway.
