Full Breakdown
Palo Alto does not publish an STR-specific occupancy cap, but limits are derived from the California Building Code, California Fire Code, and the Uniform Housing Code as adopted by the city. The commonly applied standard is two persons per bedroom plus up to two additional persons, subject to minimum square footage per occupant under H and S Code 17920.3. Sofa beds and air mattresses in common areas do not increase the lawful occupancy when the count would exceed code. Hosts should post the maximum allowed number of guests in the listing and on the premises, and must not advertise capacities that exceed code. Violations are enforced through building and code enforcement, particularly when tied to noise or parking complaints. Hosts of larger groups should check with Palo Alto Building at 650-329-2100 before accepting reservations that may exceed safe limits.
