Arizona security deposit law lives in one statute, A.R.S. § 33-1321, and it runs on four numbers:
- The most you can collect is one and a half months’ rent, counting every refundable deposit and any required prepaid rent combined, whatever the lease calls them.
- After the resident moves out and asks for the deposit back, you have 14 days, excluding weekends and legal holidays, to mail the refund with an itemized list of deductions.
- Wrongful withholding costs you the amount due plus twice the amount wrongfully withheld.
- Once you mail the itemized list, the resident has 60 days to dispute it. After that, your accounting is final.
No interest is owed, and no separate account is required. Every rule in this guide is checked against the Arizona Residential Landlord and Tenant Act as it stands in 2026, including two changes older guides still miss: the 60-day dispute window added in 2018 and the small claims limit that rose to $5,000 in 2025. To see how Arizona compares with other states, start with our guide to landlord-tenant laws by state.
How Much Can a Landlord Charge for a Security Deposit in Arizona?
One and a half months’ rent, total. A.R.S. § 33-1321(A) caps security “however denominated, including prepaid rent,” which is the statute’s way of saying labels do not matter. A refundable pet deposit, a cleaning deposit, and a required last month’s rent all count toward the same ceiling. On a $1,600 home, everything refundable you require can add up to $2,400 and no more. A resident may volunteer to prepay additional rent, and the statute allows that, but you cannot demand it as a condition of the lease.
Nonrefundable fees sit outside the cap, on one strict condition from § 33-1321(B): their purpose must be stated in writing. Any fee or deposit the lease never designates as nonrefundable is refundable, whatever you meant it to be. A $200 “cleaning fee” with no written designation comes back to the resident at move-out, so label every fee before signing, and say in the lease exactly what it covers.
What Does Arizona Require From the Landlord at Move-In?
Three things, and most first-time landlords have never heard of the third. Under § 33-1321(C) you must give the resident 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. If the resident asks when that inspection will happen, you have to tell them. The only exception covers evictions for a material and irreparable breach where the landlord reasonably fears violence, and there the joint inspection duty drops away.
Take the move-in form seriously. It is the document every deposit dispute eventually turns on, because it separates the damage that predates the resident from the damage they caused.
What Can a Security Deposit Be Used For in Arizona?
Three uses, all in § 33-1321(D): unpaid rent, charges spelled out in the signed lease agreement (subject to your duty to mitigate), and damages from the resident’s failure to meet the duties in § 33-1341. Those duties include keeping the home reasonably clean and safe, disposing of garbage, using plumbing, electrical, and HVAC systems reasonably, and not deliberately or negligently damaging the property. In practice that covers broken fixtures, wall holes, pet destruction, trash left behind, and the deep cleaning a neglected home needs.
Ordinary aging of the home is off limits. Faded paint, worn carpet in the walkways, and small nail holes are the cost of someone living there, and Arizona’s court-connected self-help resources at AZLawHelp draw the deduction line at damage “beyond ordinary wear and tear.” Our guide to normal wear and tear in a rental walks that boundary item by item, and for a deeper look at lawful deductions, see what a landlord can deduct from a security deposit.
How Long Does a Landlord Have to Return a Security Deposit in Arizona?
14 days, excluding Saturdays, Sundays, and legal holidays, which works out to roughly three weeks on the calendar. Under § 33-1321(D), the statutory clock starts once three things have all happened: the tenancy has ended, the resident has returned possession, and the resident has demanded the deposit. AZLawHelp coaches residents to make that demand in writing at move-out, with a forwarding address, delivered by hand or certified mail, so expect the clock to start the day the keys come back.
Do not build a strategy around a missing demand. Mail the itemized list and any refund on the move-out clock regardless, by first-class mail to the resident’s last known place of residence, unless they arranged something different in writing. With no forwarding address on file, the last known address can be the rental itself. Keep proof of the mailing date, because that date starts the second clock: the resident then has 60 days to dispute your deductions, and if they stay silent, the statute deems your accounting “valid and final” and waives any further claims. That waiver clause entered the statute in 2018, and plenty of older articles still describe Arizona law without it. Deadlines like this vary widely across the country, and our state-by-state guide to how long a landlord has to return a deposit shows just how much.
What Happens If a Landlord Wrongfully Withholds a Deposit?
The resident recovers the money due plus damages equal to twice the amount wrongfully withheld (§ 33-1321(E)). Withhold $900 you were not entitled to, and you owe that $900 back plus $1,800 on top, or $2,700 in all. The penalty keys to the amount wrongfully withheld, not the whole deposit, which makes precise itemization your best protection: a landlord who mails an honest, documented accounting on time has little exposure even if one line item gets challenged.
The penalty reaches any failure to comply with subsection D. Missing the 14-day deadline, skipping the itemized list, and taking deductions the law does not allow all qualify. These fights land in small claims court, where the jurisdictional limit rose from $3,500 to $5,000 in 2025 (A.R.S. § 22-503, amended by SB 1022). Nearly every Arizona deposit fits inside that ceiling even after doubling, so assume a wronged resident has an easy, lawyer-free path to collect.
Does Arizona Require Interest or a Separate Escrow Account?
No to both. Nothing in § 33-1321 requires a landlord to pay interest on a held deposit or to keep it in a dedicated account, and subsection G even lets a landlord use refundable deposits during the tenancy in line with the property management agreement, as long as every refundable dollar is there to return at the end. Investors arriving from states that mandate escrow and annual interest can relax those habits here, though a separate deposits account remains smart bookkeeping.
One more subsection worth knowing if you buy or sell occupied rentals: under subsection H, whoever holds the landlord’s interest when the tenancy ends is bound by the deposit rules. Buy a home with a resident in place and the refund obligation is yours, so collect the deposit ledger and the move-in forms at closing.
How Do You Return a Deposit Without a Dispute?
Deposit disputes are documentation contests, and the winning file is built the day the resident moves in. Across the 40,000+ homes we manage, the expensive deposit fights almost always trace back to a missing document rather than a dishonest landlord. The routine that keeps Arizona landlords out of small claims court:
- Inspect at move-in and move-out, with dated photos and the statutory move-in form signed by the resident. Invite them to the move-out inspection, since the statute gives them the right to attend anyway.
- Itemize with real numbers. Attach invoices or estimates to every deduction. “Repairs: $600” invites a lawsuit, while a contractor’s invoice usually ends the argument.
- Calendar the clock from move-out day. Fourteen days excluding weekends and holidays is tight when a repair estimate is slow, so start lining up vendors before the keys come back.
- Mail with proof. First-class mail to the last known address satisfies the statute, and a certificate of mailing proves your date for both the 14-day duty and the 60-day finality window it starts.
The same discipline pays off across the whole tenancy. Our guide to managing a rental property covers the inspection and record-keeping systems behind uneventful move-outs.

FAQ
Can a resident use the security deposit as the last month’s rent in Arizona?
Not without the landlord’s written agreement. Rent stays due every month of the term, and a resident who skips the final payment risks a five-day nonpayment notice under A.R.S. § 33-1368(B), plus a deposit that can no longer stretch to cover any damage. The statute lets the landlord apply the deposit to unpaid rent after the tenancy ends, but it gives the resident no right to spend it early.
Are pet deposits included in Arizona’s security deposit limit?
Yes, if they are refundable. Every refundable deposit, however labeled, counts toward the one-and-a-half-month cap in § 33-1321(A). A genuinely nonrefundable pet fee sits outside the cap, but only if the lease designates it as nonrefundable in writing and states its purpose. An undesignated fee is refundable by statute.
Can a landlord raise the security deposit in the middle of a lease?
Not during a fixed-term lease unless the lease itself allows it or both sides agree in writing. On a month-to-month tenancy, terms can change with 30 days’ written notice before the next monthly rental date, the same notice period that governs the tenancy under A.R.S. § 33-1375. Even then, the total refundable security can never exceed one and a half months’ rent.
What if the resident never demands the deposit or leaves no forwarding address?
Mail the itemized list and any refund anyway. The statute’s 14-day clock technically waits on the resident’s demand, but mailing to the last known address, which can be the rental unit itself, shows good faith and starts the 60-day window that makes your accounting final. Keep the certificate of mailing either way.
How can a resident dispute deposit deductions in Arizona?
In writing, within 60 days of the day the landlord mailed the itemized list, or the deductions become final under § 33-1321(D). If the landlord refuses to correct a wrongful deduction, the resident can sue in small claims court for up to $5,000 and recover the amount due plus twice the amount wrongfully withheld.
