Fire Sprinkler Requirements
Chandler's amended Building Code requires automatic fire sprinklers throughout every Group R occupancy, apartments, condos, group homes, hotels, with one carve-out: detached one- and two-family houses in Group R-3 are exempt, so a typical single-family home in Chandler doesn't need a residential sprinkler system.
