Run the numbers on a $1,600 rental in Mesa: the absolute most you can collect up front is $2,400, and that ceiling swallows security, pet deposit, prepaid rent, and anything else you collect as security, however you label it. Arizona wrote its deposit rules with more precision than almost any other part of the Residential Landlord and Tenant Act, and it backs them with a double-damages penalty. So that's where this guide starts.

Taking the deposit: the 1.5-month ceiling and the fee-labeling trap

A.R.S. § 33-1321(A) bars you from demanding or receiving security of more than one and one-half month's rent, and it counts prepaid rent toward the cap. A tenant may volunteer to pay more (say, prepaying six months because they lack credit history), but it has to be genuinely voluntary; you can't require it.

The trap most landlords miss sits in subsection (B): the purpose of every nonrefundable fee must be stated in writing, and any fee or deposit not explicitly designated nonrefundable is refundable (A.R.S. § 33-1321(B)). Call it a "cleaning fee" in conversation but never label it nonrefundable in the lease, and Arizona law says the tenant gets it back.

Move-in paperwork is mandatory, not best practice: give the tenant a signed copy of the lease, a move-in form for recording existing damage, and written notice that they may be present at the move-out inspection (A.R.S. § 33-1321(C)). Skipping that notice undercuts your deductions before the tenancy even starts.

Returning the deposit: 14 business days, itemized, or you owe double

After the tenancy ends and the tenant returns possession and demands the deposit, you have 14 days, excluding Saturdays, Sundays, and legal holidays, to deliver an itemized list of deductions plus whatever balance is due (A.R.S. § 33-1321(D)). Weekends don't count, so the real-world window is closer to three weeks, but it's still one of the tighter deadlines in the country.

Blow the deadline or the itemization and the tenant can sue for the property and money due plus damages equal to twice the amount wrongfully withheld (A.R.S. § 33-1321(E)). On a $2,400 deposit, sloppy paperwork can turn into a $7,200 problem. This is exactly the kind of per-state clock Rentari tracks automatically when a lease ends.

Deduct only unpaid rent, other charges the lease allows, and damage beyond ordinary wear. If the tenant asked to attend the move-out inspection, let them; a walkthrough with photos and both signatures beats a courtroom argument every time. Deposit clocks differ sharply across the region (our Colorado guide covers that state's very different timeline), so don't recycle another state's move-out checklist here.

Entry rules: two days' notice, with a repair-request shortcut

Give at least two days' notice before entering, enter only at reasonable times, and keep the purpose legitimate: inspection, repairs, services, or showings (A.R.S. § 33-1343). Emergencies need no notice. One genuinely useful wrinkle: when a tenant submits a maintenance request, that request itself counts as consent to enter to do the work, no separate notice needed.

Rent, late fees, and the 2025 rental-tax change

Arizona has no statutory grace period and no cap on late fees, but § 33-1368(B) adds a real condition: a late fee only exists if it's set out in a written rental agreement, and it must be reasonable. Courts here have refused fees that operate as penalties, so tie yours to what a late payment actually costs you, not to pressure.

Rent increases are uncapped, and cities are expressly forbidden from controlling rents on private property (A.R.S. § 33-1329); repeal bills like 2025's HB 2839 have died in committee. On a month-to-month tenancy, change the rent the same way you'd end the tenancy: written notice at least 30 days before the next periodic rental date (A.R.S. § 33-1375). Fixed-term rents are locked until renewal. Neither Idaho nor Montana caps increases either; the Mountain West prices at market.

The big money change took effect January 1, 2025: cities can no longer levy transaction privilege tax on residential rent of 30 days or longer, and landlords were required to stop charging tenants that 2 to 4 percent line item (SB 1131, 2023). If a tenant challenges a charge as disguised rental tax, the burden of proof sits on you. Scrub old lease templates and ledger codes; the Department of Revenue's residential rental guidelines spell out what changed.

The eviction ladder: five days, ten days, or none at all

Arizona's notices are short and specific (A.R.S. § 33-1368):

  • Nonpayment: a written 5-day notice to pay or the agreement terminates. If the tenant tenders all past-due rent plus the written, reasonable late fee before you file suit, you must accept it and the tenancy continues (A.R.S. § 33-1368(B)).
  • Material lease violation: a 10-day notice, with the tenancy surviving if the breach is cured within those 10 days (A.R.S. § 33-1368(A)).
  • Health and safety violations: a 5-day notice with a 5-day cure.
  • Irreparable breaches (serious criminal activity on the premises): immediate termination notice, no cure.

When a notice expires, you file a special detainer action in justice court, and Arizona justice courts move fast; hearings land within days, not months. What you cannot do is act without the court: changing locks, blocking entry, or cutting utilities lets the tenant recover possession or terminate plus up to two months' rent or twice their actual damages, whichever is greater (A.R.S. § 33-1367).

Tenants hold real counter-remedies, which is worth knowing before you slow-walk a repair. After written notice, a tenant can hire a licensed contractor to fix a minor defect you ignored for 10 days and deduct up to the greater of $300 or half a month's rent (A.R.S. § 33-1363), and separate statutes cover essential services like air conditioning, which in a Phoenix summer is treated as the emergency it is.

Disclosures Arizona actually requires

Three state-specific items, all in writing at or before move-in: the name and address of the property manager, the owner or the owner's agent for service of process and notices (A.R.S. § 33-1322), and a notice that the Residential Landlord and Tenant Act is available free on the Arizona Department of Housing's website. Keep the information current; successors and buyers inherit the duty.

Arizona also runs one of the country's few bedbug statutes: you can't knowingly lease an infested unit, and you must give tenants bedbug educational materials (A.R.S. § 33-1319). Pre-1978 buildings add the federal lead-based paint disclosure and pamphlet.

What changed in 2024 through 2026

The rental TPT repeal is the change with dollars attached: passed as SB 1131 in 2023, it took effect January 1, 2025, ending city taxes on long-term residential rent statewide. Its tenant-enforcement provision (the burden-of-proof rule above) is scheduled to sunset January 1, 2027, so the compliance risk is front-loaded on 2025 and 2026 books.

Beyond that, the 2024 and 2025 sessions left the core Act's numbers alone. Rent-control repeal bills died again, the 5-day and 10-day notices are unchanged, and the deposit cap has been 1.5 months for decades. The full current text of Title 33 is on the Arizona Legislature's site; chapter 10 is the Residential Landlord and Tenant Act.

Arizona landlord FAQ

How long do I have to return a security deposit in Arizona?

Fourteen days after termination, delivery of possession, and the tenant's demand, excluding weekends and legal holidays, with an itemized deduction list (A.R.S. § 33-1321(D)). Miss it and you're exposed to twice the amount wrongfully withheld.

Can I keep a cleaning fee automatically?

Only if the lease designates it nonrefundable in writing and states its purpose. Any fee not labeled nonrefundable is refundable by statute (A.R.S. § 33-1321(B)).

What notice do I give before raising rent?

On month-to-month, written notice at least 30 days before the next periodic rental date (A.R.S. § 33-1375). There's no cap on the size of the increase, and cities can't impose one (A.R.S. § 33-1329).

Do I still collect city rental tax in 2026?

No. Since January 1, 2025, cities can't tax long-term residential rent and you can't pass a repealed tax through to tenants. Short-term stays under 30 days still carry TPT.

How fast is an Arizona eviction for nonpayment?

A 5-day notice, then a special detainer filing in justice court, which sets hearings within days. But if the tenant pays everything owed, including the written late fee, before you file, you must take the money and stop.

This is general information for Arizona rental owners, not legal advice. Statutes change and courts add nuance a summary can't carry, so before you rely on any deadline or notice period here, check the current text of A.R.S. Title 33, chapter 10 or talk to an Arizona landlord-tenant attorney.
