AZ SB1644

Allows tenants who are victims of domestic violence or sexual assault to terminate rental agreements early without penalty by providing written notice with specified documentation (protective order, law enforcement report, or statement from qualified third party) within 30 days of the incident.

Requires tenants to pay only rent through the termination date plus outstanding obligations; landlords may retain prepaid rent for the termination month but cannot withhold security deposits for early termination if requirements are met.

Permits tenants to require landlords to rekey or replace locks at the tenant's expense; landlords may retain a key copy but must refuse to provide keys to persons named in protective orders.

Prohibits landlords from providing property access to persons named in protective orders unless escorted by law enforcement; makes such persons civilly liable for economic damages caused by the lease termination.

Defines "qualified third party" to include physicians, psychiatrists, psychologists, social workers, nurses, therapists, and domestic violence service providers who can verify victim status.
