Arizona Revised Statutes Title 33. Property § 33-1366. Fire or casualty damage

1. Immediately vacate the premises and notify the landlord in writing within fourteen days thereafter of his intention to terminate the rental agreement, in which case the rental agreement terminates as of the date of vacating.

2. If continued occupancy is lawful, vacate any part of the dwelling unit rendered unusable by the fire or casualty, in which case the tenant's liability for rent is reduced in proportion to the diminution in the fair rental value of the dwelling unit.
