ARLTA Security Deposit Caps & Return Timelines
The Arizona Residential Landlord and Tenant Act (ARLTA) places clear statutory caps on deposits and establishes prompt accounting rules upon vacancy.
1.5 Months' Rent Cap
Under A.R.S. § 33-1321(A), a landlord may not demand or receive security deposit and prepaid rent exceeding 1.5 times monthly rent, unless voluntarily agreed by the tenant.
14 Business Days Return
Under A.R.S. § 33-1321(D), itemized deduction statements and refunds must be sent within 14 days, excluding weekends and legal holidays, following surrender and tenant demand.
Move-Out Walkthrough Right
At move-in, the landlord must tell the tenant they may be present at the move-out inspection, and on the tenant's request must say when it will take place (§33-1321(C)). Protect yourself using our inspection checklist.
30-Day Notice & Double Damages Remedies
Month-to-Month Notice (30 Days)
Under A.R.S. § 33-1375(B), either party may terminate a periodic month-to-month tenancy with at least 30 calendar days' written notice before the next rent period. Deliver proper notice with our move-out notice letter.
Double Damages Liability
Under A.R.S. § 33-1321(E), landlords failing to comply with the 14-day timeline face liability for the amount wrongfully withheld plus double damages. Demand your refund with our deposit return letter.
Phoenix & Tucson Rental Dynamics
In Phoenix and Tucson, desert climates make cooling essential. If a unit has air conditioning, the landlord must keep it in working order (A.R.S. § 33-1324); § 33-1364 gives tenants remedies if cooling is deliberately or negligently not supplied. Make sure to establish your move-in condition thoroughly with our prorated rent letter template.
Arizona Prorated Rent Frequently Asked Questions
How is prorated rent calculated in Arizona?
The Arizona Residential Landlord and Tenant Act does not prescribe a mandatory proration formula. Leases govern the calculation, with most Arizona housing providers calculating daily rent by dividing monthly rent by the actual number of days in the month, while others utilize a 30-day standard.
What is the maximum security deposit allowed in Arizona?
Under A.R.S. § 33-1321(A), a landlord cannot demand or receive a security deposit and prepaid rent combined exceeding one and one-half (1.5) months' rent, unless the tenant voluntarily agrees to pay a higher amount.
What is the deadline for returning a security deposit in Arizona?
Under A.R.S. § 33-1321(D), landlords must deliver an itemized list of deductions and refund any remaining balance within 14 days, excluding Saturdays, Sundays, and legal holidays (14 business days), after termination of tenancy, delivery of possession, and demand by the tenant.
What is the penalty if an Arizona landlord withholds a deposit wrongfully?
Under A.R.S. § 33-1321(E), if a landlord fails to comply with the 14-day itemization and return requirement, the tenant may recover the money due plus damages in an amount equal to twice the amount wrongfully withheld (double damages).
How much notice is required to end a month-to-month lease in Arizona?
Under A.R.S. § 33-1375(B), either the landlord or the tenant may terminate a month-to-month tenancy by delivering written notice to the other party at least 30 calendar days prior to the periodic rental date specified in the notice.
Does an Arizona tenant have the right to attend the move-out inspection?
Yes. At move-in, the landlord must tell the tenant they may be present at the move-out inspection, and on the tenant's request must say when it will take place (§33-1321(C)).
