Arizona Landlord-Tenant Laws
Arizona Security deposits
Arizona caps everything a landlord can demand up front — security deposit, prepaid rent, and refundable fees combined, however they are labeled — at one and one-half month's rent, though a tenant may volunteer more.
Arizona Rent increase notice
Arizona has no statute requiring advance notice of a rent increase for standard rentals — the familiar 30-day convention for month-to-month tenancies is derived from ARS 33-1375(B), which lets either party end a month-to-month tenancy on 30 days' written notice before the periodic rental date, so a landlord who raises rent effectively offers new terms the tenant can decline by leaving.
Arizona Late fees
Arizona sets no dollar or percentage cap on residential late fees and mandates no grace period — rent is 'payable without demand or notice at the time and place agreed on by the parties' (ARS 33-1314(C)), so a lease-based late fee can begin accruing the day after rent is due.
Arizona Entry notice
Arizona landlords must give at least two days' notice before entering a rental for inspections, repairs, services, or showings, and may enter only at reasonable times — with no notice needed in an emergency, where giving it is impracticable, or where the tenant's own maintenance request supplies the permission.
How this record was verified: Direct read of statute text on the official Arizona Legislature site (azleg.gov): ARS 33-1321 and 33-1343 each read in full twice (independent fetches matched verbatim), ARS 33-1368, 33-1375, 33-1329, 33-1376, and 33-1314 read in full, plus trap-check reads of the mobile-home statutes ARS 33-1414 (late fees) and 33-1432 (90-day rent-increase notice) to confirm those figures do NOT apply to standard rentals. Pending-bill statuses (HB 2337 of 2025, HB 4122 and HB 2243 of 2026) checked against azleg.gov bill text and legislative trackers 2026-07-09; all died without committee action.
