Arizona Senate Bill 1142 keeps authority over residential landlord-tenant rules at the state level, barring cities and counties from passing their own ordinances on topics the Arizona Residential Landlord and Tenant Act already covers. For landlords, that means the rules on tenant screening, security deposits, and move-in fees look the same in Tucson, Scottsdale, and Flagstaff. For tenants, it means local councils cannot add protections the state hasn’t adopted.
What State Preemption Actually Does
Arizona has long consolidated rental regulation at the state level rather than letting municipalities write their own. SB 1142 continues that pattern by blocking local governments from enacting ordinances on landlord-tenant subjects already addressed by state law. When state law occupies a topic, a city or county cannot impose additional or conflicting requirements on either side of the lease.
The bill operates within the framework of the Arizona Residential Landlord and Tenant Act, codified at A.R.S. Title 33, Chapter 10, which governs lease disclosures, deposits, and the eviction process. The practical effect for landlords with units in multiple jurisdictions is a single rulebook rather than a patchwork.
Tenant Screening and Source of Income
One of the clearest effects of state preemption shows up in tenant screening. The federal Fair Housing Act prohibits discrimination based on race, color, religion, sex, national origin, familial status, and disability. It does not list source of income as a protected class. Arizona state law likewise does not require landlords to accept tenants who pay rent through Section 8 housing choice vouchers, Social Security, veterans’ benefits, or disability payments.
Because SB 1142 reinforces state authority over screening standards, cities and counties cannot pass their own ordinances requiring landlords to accept voucher holders or specific income sources. A landlord may choose to participate in the Section 8 program, but participation remains voluntary across Arizona.
Federal and state anti-discrimination rules still govern every application. Rejecting an applicant because of race, disability, or familial status is illegal no matter how the decision is framed. Credit history, rental history, and income-to-rent ratios remain permissible criteria so long as they are applied consistently to every applicant.
Security Deposit Limits
Under A.R.S. § 33-1321, a landlord cannot demand or receive a security deposit, including prepaid rent, that exceeds one and one-half months’ rent.1Arizona Legislature. Arizona Revised Statutes 33-1321 – Security Deposits For a unit renting at $1,400 per month, the ceiling is $2,100. A tenant can voluntarily pay more upfront, but a landlord cannot require it.
The statute also draws a sharp line between refundable and nonrefundable charges. The purpose of every nonrefundable fee or deposit must be stated in writing by the landlord. Any fee or deposit not explicitly labeled nonrefundable is automatically treated as refundable.1Arizona Legislature. Arizona Revised Statutes 33-1321 – Security Deposits A vague “move-in fee” with no written label becomes money the tenant can demand back at move-out.
Returning the Deposit After Move-Out
When the tenancy ends, a landlord can apply the deposit to unpaid rent, lease-specified charges, and damages caused by the tenant’s failure to maintain the property. The landlord then has 14 business days (excluding weekends and legal holidays) after the tenant moves out and demands the deposit to deliver an itemized list of deductions along with any balance owed.1Arizona Legislature. Arizona Revised Statutes 33-1321 – Security Deposits Unless the tenant arranges otherwise in writing, the list and refund go to the tenant’s last known address.
The penalty for getting this wrong is steep. If a landlord fails to return the deposit and provide the itemized list within the 14-business-day window, the tenant can recover the amount owed plus damages equal to twice the amount wrongfully withheld.1Arizona Legislature. Arizona Revised Statutes 33-1321 – Security Deposits A landlord who improperly keeps $1,000 can end up owing $3,000. Tenants typically file these claims in justice court.
Arizona law requires tenants to return the unit in the same condition as move-in, with an exception for ordinary wear and tear.2Arizona Department of Housing. Arizona Residential Landlord and Tenant Act Faded paint, minor scuffs, and lightly worn carpet are wear and tear. Holes in walls, pet-stained carpet, and misuse damage are deductible. The strongest protection on both sides is a dated, photographed move-in inspection; without it, move-out disputes come down to credibility.
Required Written Disclosures
Several disclosures are mandatory at or before the start of the tenancy. Under A.R.S. § 33-1322, every landlord must disclose in writing the name and address of the property manager and the owner (or someone authorized to accept legal notices for the owner).3Arizona Legislature. Arizona Revised Statutes 33-1322 – Disclosure and Tender of Written Rental Agreement Skipping this counts as material noncompliance with the rental agreement.
The landlord must also tell the tenant in writing that the Arizona Residential Landlord and Tenant Act is available on the Arizona Department of Housing website.3Arizona Legislature. Arizona Revised Statutes 33-1322 – Disclosure and Tender of Written Rental Agreement If the lease is written, the landlord delivers a signed copy to the tenant, the tenant signs and delivers a copy back within a reasonable time, and every blank in the document must be filled in.
Lead Paint on Pre-1978 Properties
Federal law layers an additional disclosure on top of state requirements for older buildings. Landlords renting units in buildings constructed before 1978 must disclose known lead-based paint and hazards, hand over any available records and reports, include a specific lead warning in the lease, and provide the EPA pamphlet “Protect Your Family from Lead in Your Home,” updated in January 2026 to reflect new dust-lead action levels.4U.S. Environmental Protection Agency (EPA). Protect Your Family from Lead in Your Home This requirement comes from federal law, not SB 1142 or the Arizona statute, but it applies to Arizona rentals all the same.
How the Rules Apply to Existing Leases
The security deposit rules, disclosure requirements, and screening standards under Arizona law apply to all rental agreements governed by the Residential Landlord and Tenant Act. New legislation generally applies to rental agreements entered into after the effective date. Leases already in force usually continue under their existing terms until renewal, when the updated rules take hold. Regardless of when a lease was signed, the statutory deadlines and penalties around security deposit returns apply to any tenancy that ends after the law’s effective date, so landlords finishing out older leases still need to meet the 14-business-day window and the itemization requirement.
