No Rialto-specific ordinance directly addresses short-term rental occupancy limits; California state default applies. General habitability and occupancy standards flow from the State Housing Law (Health and Safety Code Sec. 17922), which adopts Uniform Housing Code requirements.
Neither the Rialto Municipal Code's transient occupancy tax chapter (RMC Chapter 3.08) nor its zoning code (Title 18) sets a maximum guest count for short-term rentals - the City has adopted no STR-specific occupancy, night-cap, or guest-limit rules. The only occupancy-related threshold in local law is definitional: RMC 3.08.020(D) classifies a person as a 'transient' when occupancy is for 30 consecutive calendar days or less, which determines whether the 9 percent transient occupancy tax applies. Absent local regulation, the California state default governs. Under Health and Safety Code Sec. 17922, the state's residential building standards must impose substantially the same requirements as the Uniform Housing Code, whose dwelling-space standards (commonly applied as roughly two persons per bedroom plus one additional occupant) set the floor for lawful occupancy of any dwelling, including one offered as a short-term rental. Property owners remain free to set their own contractual guest limits in rental listings and agreements.
Because there is no local STR occupancy ordinance, the City cannot cite a host simply for guest count. Overcrowding that violates state habitability standards adopted under Health and Safety Code Sec. 17922, or conditions creating a nuisance under RMC Chapter 18.72 (Property Maintenance - Nuisances), can be enforced through code enforcement action, administrative citations under RMC Chapter 1.10, or misdemeanor/infraction prosecution under RMC 1.16.010.
