San Bernardino County
Rialto does not impose STR-specific guest-parking minimums because the city has no STR ordinance. Hosts must rely on the general framework: Title 18 Zoning sets off-street parking minimums for the underlying dwelling (typically 2 covered spaces per single-family home in Rialto's R-1 zones), Title 10 Vehicles and Traffic governs on-street parking (including the 72-hour vehicle-storage rule under Cal. Veh. Code §22651(k)), and oversize/RV parking is restricted near the Rialto Municipal Airport (L67) AIA overlay and on residential streets per Title 10 posted-zone rules.
