Tustin, CA Short-Term Rentals: Occupancy Limits (2026)

Cities that permit STRs typically cap overnight guests (for example, two per bedroom plus two). Tustin has no such STR occupancy standard because it does not allow short-term rentals at all. Per the City's official FAQ, any residential rental under 30 days is a prohibited hotel/motel use in residential districts, so there is no scenario in which a residential vacation-rental occupancy cap would apply. The only occupancy-related controls on Tustin dwellings are the generally applicable standards: the California Building Code and Housing Code occupancy and habitability limits enforced through Tustin's Building Division and Code Enforcement, and the zoning code's definitions of dwelling unit and family. These apply to long-term residents and tenants, not to a sanctioned STR guest count, because no sanctioned STR exists. For lawful transient lodging, occupancy is governed by the hotel or motel's own building-code-rated capacity in an appropriately zoned commercial location, not by a residential STR rule. Anyone considering listing a Tustin home should understand that the relevant constraint is not a guest cap but the outright prohibition: the minimum lawful residential rental term is 30 calendar days, and only then is it a permitted long-term tenancy rather than a banned transient use.
