Arizona landlord rules: late fees, deposits and rent increases

Arizona's Residential Landlord and Tenant Act limits deposits and sets a short return deadline. It puts no number on late fees or rent increases. Here is what the Arizona Revised Statutes say, with the section for each rule.

Late fees in Arizona

Limit

None in the statute. A.R.S. tit. 33, ch. 10

Grace period

None in the statute. A.R.S. tit. 33, ch. 10

Other conditions

The statute refers to "a reasonable late fee set forth in a written rental agreement." The words appear in the section on unpaid rent, as part of what a tenant pays to bring the lease current. A.R.S. § 33-1368(B)

Security deposits in Arizona

Maximum deposit

One and a half months' rent, including prepaid rent. A.R.S. § 33-1321(A)

Return deadline

14 days, not counting Saturdays, Sundays and legal holidays. The time runs after the tenancy ends, the tenant delivers possession and the tenant demands the deposit. A.R.S. § 33-1321(D)

Itemized deductions

Required, within the same 14 days. Mail the itemized list with the amount due to the tenant's last known address. The tenant has 60 days to dispute the deductions. A.R.S. § 33-1321(D)

Interest

The statute doesn't require it. A.R.S. § 33-1321

How it's held

No special account or bond in the statute. A.R.S. § 33-1321

Penalty

The money due plus damages of twice the amount wrongly kept. A.R.S. § 33-1321(E)

Rent increases in Arizona

Notice to raise rent

No statute sets a notice period for a rent increase. The closest rule covers ending a month-to-month tenancy: written notice at least 30 days before the periodic rental date. Check your lease for its own notice term. A.R.S. § 33-1375(B)

Statewide cap

None in the statute. A.R.S. tit. 33, ch. 10

City rent control

Not allowed. Cities and towns don't have the power to control rents on private residential property. A.R.S. § 33-1329
