Rent increases in Arizona

Arizona has no statute specifically on rent-increase notice. The landlord changes terms by giving the written notice needed to end the periodic tenancy: 30 days before a rent day (month-to-month) or 10 days (week-to-week). Notice sent by registered or certified mail counts as received on actual receipt or 5 days after mailing, whichever is first. (A.R.S. §§ 33-1375(A)-(B), 33-1313(B))

No separate rent-increase rule: the periods below are the notice to end a periodic tenancy.

• The notice must be in writing.
• Mailed notice: add 5 days.
• The change can only start at the end of a rental period (on a rent day).

Earliest date the new rent can start, with rent due on the 1st, worked out from the Arizona rule above:

• For a month-to-month tenant of 1 year raising rent 5% or a month-to-month tenant of 3 years raising rent 12%: Friday, January 1, 2027
• For a week-to-week tenant raising rent 5%: Tuesday, December 1, 2026

No Arizona statute addresses raising rent during a fixed-term lease; the rental agreement may set rent and term (A.R.S. § 33-1314(A)). (A.R.S. § 33-1314)

Cities, including charter cities, and towns may not control rents on private residential property; government-owned, financed, insured or subsidized property is excepted. (A.R.S. § 33-1329)

A landlord may not retaliate by increasing rent after a code complaint, a complaint under § 33-1324, or joining a tenants' union. A complaint within 6 months before the increase creates a presumption of retaliation (not if made after notice of termination). (A.R.S. § 33-1381)

• Without a fixed term, a tenancy is month-to-month (week-to-week for a weekly roomer) (A.R.S. § 33-1314(D)).
• Adding submetering or ratio utility billing to an existing tenancy requires 90 days' notice (A.R.S. § 33-1314.01(G)).

Security deposit

Security, however labeled, including prepaid rent, may not exceed one and one-half months' rent. A tenant may still choose to prepay more rent. Return deadline: 14 business days after the tenancy terminates.

Tenant's notice to move out

30 days, ending with a rental period

Notice for unpaid rent

5 days (pay or move out)

How a written notice is delivered (eviction-notice rules)

The tenant 'receives' a notice when it is delivered in hand or mailed by registered or certified mail to the place the tenant designated or, if none, to the last known residence (A.R.S. § 33-1313(B)).

Notice for other lease violations

10 days (fix it or move out)

Small claims court limit

$5,000 — where most deposit and rent disputes are filed.

Repairs

Time to repair: 10 days; urgent: 5 days. Repair and deduct: allowed with limits; withholding rent: allowed with limits.

Deposit kept wrongly

If the landlord fails to comply, the tenant recovers the money due plus damages equal to twice the amount wrongfully withheld (§ 33-1321(E)).
