Owner-occupied single-family houses, owner-occupied portions of duplexes, and owner-occupied condominium units shall be exempted from the requirement to have and maintain a fire certificate of occupancy.
(2) A building or portion thereof which receives a certificate of occupancy from the city's building official upon completion of construction or major rehabilitation shall simultaneously receive a fire certificate of occupancy from the fire chief if their use or occupancy so requires.
(3) Buildings which have a change in use or occupancy shall become subject to the fire certificate of occupancy requirement.
(4) Commercial buildings and residential occupancies shall be subject to the ongoing requirement to maintain a fire certificate of occupancy. These buildings shall be issued fire certificates of occupancy and shall be subject to regular inspection, based on the date of the building's last complete certificate of occupancy inspection, subject to the terms of this article.
It is a misdemeanor to rent or lease, or permit the occupancy of, a building or structure or portion thereof which does not have a fire certificate of occupancy.
