Identify the reason first
Under A.R.S. § 33-1368, unpaid rent generally involves a five-day written notice. A curable material lease breach generally involves ten days, while certain health-and-safety breaches involve five days. Material and irreparable breaches follow a different process. These categories are not interchangeable.
Separate termination from enforcement
For month-to-month tenancies, A.R.S. § 33-1375 generally requires written notice at least 30 days before the periodic rental date stated in the notice. Fixed-term leases and special circumstances require their own review. A notice alone does not authorize taking possession outside the applicable legal process.
Calculate receipt carefully
A.R.S. § 33-1313 addresses notice and receipt. For registered or certified mail, deemed receipt is the earlier of actual receipt or five days after mailing. The governing rule, delivery method, lease, and reason for the notice all matter when calculating a deadline.
Have the facts reviewed
Gather the lease, ledger, communications, incident records, and prior notices before selecting a form. Ask an Arizona attorney to confirm the notice, service method, and next steps for an active dispute. This page is educational and is not a notice template or individualized legal advice.
