What is Market Rent and Month to Month Renewals

Published 10/15/2025
When a lease ends and a tenant stays month-to-month, rent can’t just be raised to “market.”
Under Arizona law (A.R.S. § 33-1375(B)), the only lawful rent increases are those:

Already defined in the lease (like returning to the un-concessed rent), or

Properly noticed to the tenant at least 30 days in advance.

If it’s not in the lease or in a written notice, it’s not enforceable.

📈 “Market rent” means nothing unless you’ve made it real — in writing.
