Arizona Security Deposit Law — Explained

The 14-Business-Day Deadline

Arizona's Residential Landlord and Tenant Act (A.R.S. § 33-1321) requires landlords to return the security deposit within 14 business days after the tenant vacates the unit and provides a written forwarding address. Arizona is one of the few states that uses business days rather than calendar days — this means Saturdays, Sundays, and legal holidays are excluded from the count, extending the practical deadline to approximately three calendar weeks.

The 14-business-day clock does not start until the landlord has both: (1) the tenant's vacating of the unit, and (2) a written forwarding address. Always provide your forwarding address in writing on or before your move-out date to start the clock running.

The 1.5-Month Deposit Cap

Arizona caps security deposits at 1.5 months' rent under A.R.S. § 33-1321(A). A landlord who charges more than this amount is in violation of the statute. If you paid a deposit exceeding 1.5 months' rent, the excess is unlawfully held and must be returned regardless of any other dispute. Check your lease and compare the deposit amount to 1.5 times your monthly rent.

Allowable Deductions

Arizona landlords may deduct from the security deposit for unpaid rent, damage beyond normal wear and tear, and other costs specified in the rental agreement. Typical non-deductible items include minor scuffs on walls, small nail holes, routine carpet wear, and faded paint from normal use. The landlord must provide a specific, itemized written statement for each deduction. Lump-sum charges without detail are insufficient.

Nonrefundable Fees vs. Security Deposits

Arizona permits landlords to charge nonrefundable fees (such as a move-in fee or pet fee) in addition to a refundable security deposit, as long as these fees are clearly identified as nonrefundable in the rental agreement and are reasonable in amount. If your lease labels a charge as a "security deposit" but the landlord later claims it was nonrefundable, this is a dispute worth raising — the label in the agreement controls.

Double Damages and Small Claims

Under A.R.S. § 33-1321(D), a landlord who wrongfully withholds a security deposit is liable for twice the amount wrongfully withheld. Arizona's justice courts handle small claims up to $3,500. For amounts between $3,500 and $10,000, file in superior court. The double-damage penalty can make even small deposits worth pursuing in court.

What to Do If Your Arizona Landlord Is Late

1. 1
   Document your move-out thoroughly Take timestamped photos and video of every room before handing over the keys. Keep your lease, move-in documentation, and all landlord communications.
2. 2
   Provide your forwarding address in writing on move-out day The 14-business-day clock doesn't start until the landlord has your written forwarding address. Email is ideal for timestamp documentation.
3. 3
   Count 14 business days carefully — excluding weekends and holidays Don't confuse business days with calendar days. 14 business days is typically about 3 calendar weeks. Use a business-day calculator to pinpoint the exact deadline.
4. 4
   Send a demand letter after the deadline passes Use RenterCalc's demand letter generator to cite A.R.S. § 33-1321 and demand your deposit plus double damages within 10 days.
5. 5
   File in justice court (small claims) Arizona's justice court small claims limit is $3,500. For larger amounts, file in superior court. You can represent yourself — attorneys are optional.
6. 6
   Consult a tenant attorney for larger deposits If your deposit exceeds $3,500 or you need to file in superior court, a tenant rights attorney may take your case on contingency, especially if double damages apply.
