Pima County cannot impose STR occupancy limits due to ARS 9-500.39 preemption. Building code occupancy standards based on bedroom count still apply to all residences.
Arizona law under ARS 9-500.39 significantly restricts local governments from regulating short-term rentals. Pima County cannot impose occupancy caps specifically targeting STRs in unincorporated areas. General building and fire code occupancy limits based on square footage and bedroom count apply to all residential properties. The 2022 legislative amendment to ARS 9-500.39 allows local jurisdictions to regulate STRs for issues of public health and safety including noise, trash, and nuisance behavior, but does not authorize occupancy-specific regulations. Most STR platforms like Airbnb and VRBO allow hosts to set their own maximum occupancy. HOA CC&Rs may restrict the number of occupants or guests in residential units. Fire code egress requirements effectively limit occupancy based on the number of bedrooms and exit routes. International Building Code as adopted by Pima County provides baseline occupancy standards.
