No, your Arizona landlord cannot raise rent without giving you proper notice. Arizona law requires landlords to provide tenants with advance written notice before increasing rent. Specifically:
For a month-to-month lease: Landlords must give at least 30 days’ written notice before a rent increase takes effect.
For a week-to-week lease: Landlords must provide at least 10 days’ written notice before raising rent.
If you have a fixed-term lease (such as a one-year lease), the landlord generally cannot raise the rent until the lease ends, unless the lease itself allows for mid-term increases.
Arizona has no rent control laws, so landlords can raise rent by any amount and as often as they wish, as long as they provide the required notice for your type of tenancy and do not act for discriminatory or retaliatory reasons.
If your landlord tries to raise your rent without giving you the required notice, the increase is not legally valid.
