Arizona mold law snapshot
Arizona does not have a mold-specific statute, but habitability rules still apply.
Under A.R.S. 33-1324, Arizona landlords must comply with applicable building codes materially affecting health and safety, make all repairs necessary to keep the premises in a fit and habitable condition, keep common areas clean and safe, maintain electrical, plumbing, sanitary, heating, ventilating, and air-conditioning systems in good working order, provide for trash removal, and supply running water, reasonable hot water, and heating/cooling as required by climate. While mold is not specifically mentioned, landlords are responsible for addressing conditions that affect health and safety, including water leaks and resulting mold growth.

Repair Notices and Rent Decisions
Start with these Arizona rules, then check the local regulations section and your property's coverage. A statutory notice period is not always a deadline for finishing every repair. Keep proof of notice and get local legal advice before changing rent payments or ending a lease.
How long does a Mesa landlord have to fix mold?
No universal mold-specific repair deadline was confirmed for Arizona in the sources reviewed for this guide. Treat timing as notice-and-condition specific: document the mold and moisture source in writing, use the cited habitability or repair source, and get local code enforcement or legal aid advice before treating any deadline as fixed.
Can Mesa tenants withhold rent for mold?
Rent withholding is permitted when a landlord fails to supply essential services such as running water, hot water, heat, air conditioning, or other essential utilities. Tenants must give reasonable notice to the landlord before withholding. Unlike some states, Arizona law does not provide for placing rent in escrow pending resolution. Tenants should be aware that withholding rent may lead to eviction proceedings, at which point they can raise habitability issues as a defense and file counterclaims.

Does mold in Mesa require relocation?
Unclear as a standalone statewide mold relocation benefit in the sources reviewed for this guide. If mold or remediation makes the unit unsafe or unusable, Arizona tenants should look to the cited habitability, essential-services, condemnation, disaster, or lease-termination rules and ask legal aid whether rent abatement, substitute housing, temporary vacancy, or termination applies.

Does mold have to be disclosed in Mesa?
Arizona does not require landlords to specifically disclose known mold conditions. However, landlords must disclose management and ownership information, and must not make material false statements about the premises condition. Additionally, landlords must provide lead-based paint disclosures for properties built before 1978 (federal requirement), bedbug educational materials, and pool safety notices where applicable. Landlords are prohibited from entering into a lease for a unit they know is infested with bedbugs.
