Rent control rules in Maricopa County, AZ — also known as rent stabilization or rent cap ordinances — limit annual rent increases and protect tenants from displacement.
Arizona law (ARS 33-1329) prohibits all cities, towns, and counties from enacting rent control or rent stabilization measures. Maricopa County has no authority to regulate rental prices. Landlords may set and increase rents without government restriction. This statewide preemption has been in effect since 1983.
Arizona state law (ARS 33-1329) expressly prohibits all cities, towns, and counties from enacting rent control or rent stabilization ordinances. This preemption applies to Maricopa County and all municipalities within it, meaning no local government in the county can cap rent increases, impose rent freezes, or regulate rental pricing. Landlords may raise rent at lease renewal or with 30 days notice for month-to-month tenancies under ARS 33-1375. The only tenant protections regarding rent are prohibitions against retaliatory rent increases under ARS 33-1381 following a tenant's good-faith complaint about code violations.
