Unincorporated San Diego County does not set a specific short-term-rental guest cap. Occupancy is governed by the general building and safety code and zoning for the dwelling, not a dedicated STR occupancy formula like the City of San Diego uses.
Because the County has no STR operating ordinance for unincorporated areas, there is no per-listing maximum-occupant formula (e.g., two-per-bedroom-plus-two) written specifically for short-term rentals. Instead, the number of occupants is limited by the underlying residential use and the California Building/Residential Code as adopted by the County, plus any septic or well capacity limits common in East County. Hosts should size occupancy to the dwelling's legal capacity and parking, and honor the county noise limits that effectively constrain large gatherings.
Overcrowding that creates a code or health hazard, or that generates a nuisance/noise violation, can be enforced under the County building and nuisance ordinances.
