Arizona Late Rent Laws for Landlords
Arizona requires late fees to be reasonable and written in the lease, and uses a 5-day notice for unpaid rent. Its security deposit return deadline is counted in business days, which is easy to miss.

Late fees in Arizona
No fixed cap. Fees must be reasonable and stated in the written rental agreement (A.R.S. §33-1368).
Whatever the state allows, a late fee is only enforceable if it's written into your lease: the amount, when it applies, and whether it's a one-time or daily fee. If the lease is silent, you generally can't charge one. Use our late fee calculator to check a fee against Arizona's rules before you put it in a lease.
Grace period
None required by state law.
Even when the law doesn't require one, a short grace period of 3–5 days is common. It gives tenants room for weekends and bank delays and makes your late fee easier to defend. Learn more in our rent grace period guide.
Notice for unpaid rent
5-day written notice to pay rent before filing a special detainer action (A.R.S. §33-1368(B)).
Serve notices exactly the way the statute describes: the right number of days, the right delivery method, and only the amounts the notice is allowed to demand. A defective notice usually means starting the clock over. Our pay or quit notice template shows what a notice typically includes.
Security deposits
Maximum 1.5 months' rent (A.R.S. §33-1321). Return within 14 business days (excluding weekends and holidays) after the tenancy ends, with an itemized list.
Rent increases
Local rent control is preempted. Increases can't take effect during a fixed lease term unless the lease allows it. Month-to-month tenancies need 30 days' notice to end, so give at least 30 days before an increase.
Use the rent increase calculator to work out the new amount and the earliest date it can take effect.
Local rules
Arizona state law preempts most local landlord-tenant regulation, but check Tucson and Phoenix for local fee and registration rules.
A typical late rent timeline in Arizona
| Stage | What happens |
|---|---|
| Due date | Rent due (e.g. the 1st). A reminder 3–7 days before is the best way to avoid the rest of this table. |
| Earliest late fee | Whatever your lease says. Arizona doesn't require a grace period. |
| Formal notice | 5-day written notice to pay rent before filing a special detainer action. |
Most late rent never needs to reach the formal notice stage. Tenants who get a clear reminder a few days before rent is due, and another on the due date, pay on time far more often. That's exactly what automated reminders are for.
