you are stating that you are simply asking if the lease terminates with notice but that you are not contemplating eviction. the answer, as i stated, is that it does not terminate because it is effective for its term. further, it is not overly presumptive for me to assume that a question pertaining to a landlord breach would not include the question of what happens if an eviction follows. otherwise, what precisely is going on?
further, if the lease terminates with the notice and the landlord does not immediately evict, in essence, the same result can apply, just with one more step. that is, the landlord would then be able to either immmediately send a notice of eviciton to the extent that the lease is terminated and the tenant has not vacated; or the landlord could immediately send a notice of termination of the then-in-effect month to month lease and when the tenant does not leave, serve notice of eviction. either way, it makes no sense because if the lease is terminated the next step is always to serve a notice of eviction.
further to the above, there is a fundamental difference in the application of recourse when either a tenant or landlord breaks a lease. when a tenant does, landlord can go after the tenant for monetary damages but can not force the tenant to move back in. when the landlord breaches the lease by illegally evicting a tenant, the recourse is that the tenant can gain re-entry and might be entitled to monetary damages. in this instance, the tenant's place of residence has been removed and the necessary recourse is diffreent than simply monetary.
as far as your statement that the AZ code does not state what happens when a landlord breaks a lease, every code does as they state clearly that any eviction can only be done through the courts. to assume that we are not talking about an eviciton but the rights to simply give notice to terminate a lease during its term when there are no defaults by the tenant is certainly a stretch and would essentially remove the entire benefits of a written lease as far as a tenant is concerned. it would basically mean that all leases are de facto month to month leases.
i am sorry if you are viewing this entire scenario through a different lens than i am but a contract is effective until its term unless provisions therein allow for its earlier termination.
