The maximum duration of a standard residential lease agreement in Arizona is one (1) year. Leases can be longer than one year, but they must be written (not oral).
Oral residential lease agreements can exist for shorter tenancies (less than one year), but it is recommended that all lease agreements be in writing. Like many states, if there is no definite, fixed term on the lease, the lease duration reflects the frequency that the rent is paid.
If the tenant pays rent weekly, they will be under a week-to-week lease unless otherwise specified. Likewise, if they pay rent monthly, the lease is considered a month-to-month lease if there is no other duration described in the contract. These lease types do not have to be in writing to be valid.
