Ariz. Rev. Stat. § 33-1342
Rules and regulations
Operative Text
A. A landlord, from time to time, may adopt rules or regulations, however described, concerning the tenant's use and occupancy of the premises. Such rules or regulations are enforceable against the tenant only if: 1. Their purpose is to promote the convenience, safety or welfare of the tenants in the premises, preserve the landlord's property from abusive use or make a fair distribution of services and facilities held out for the tenants generally. 2. They are reasonably related to the purpose for which adopted. 3. They apply to all tenants in the premises in a fair manner. 4. They are sufficiently explicit in prohibition, direction or limitation of the tenant's conduct to fairly inform the tenant of what the tenant must or must not do to comply. 5. They are not for the purpose of evading the obligations of the landlord. 6. The tenant has notice of them at the time the tenant enters into the rental agreement. B. A rule or regulation adopted after the tenant enters into the rental agreement is enforceable against the tenant if a thirty day notice of its adoption is given to the tenant and it does not constitute a substantial modification of the tenant's rental agreement. C. If state, county, municipal or other governmental bodies adopt new ordinances, rules or other legal provisions affecting existing rental agreements, the landlord may make immediate amendments to lease agreements to bring them into compliance with the law. The landlord shall give a tenant written notice that the tenant's lease agreement has been amended, and the notice shall provide a brief description of the amendment and the effective date.
Arizona Revised Statutes § 33-1342 governs when a landlord's rules and regulations are legally binding on tenants. A rule is only enforceable if it serves a legitimate purpose—such as safety, property preservation, or fair distribution of services—applies fairly to all tenants, is clearly written, and was disclosed to the tenant before or at the time of signing. Rules added after move-in require at least 30 days' written notice and cannot substantially alter the terms of the existing rental agreement; however, rules required by new government law may take effect immediately with written notice.
Plain English — not legal advice.
Property owners and managers operating under A.R.S. § 33-1342 generally ensure that any house rules are documented and provided to prospective tenants before or at lease signing. Rules introduced after a tenancy begins are typically delivered in writing at least 30 days in advance and are reviewed to confirm they do not constitute a substantial modification of the existing agreement. When a new state, county, or municipal law requires a lease amendment, compliant operators provide written notice that identifies the specific change and its effective date.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Under A.R.S. § 33-1342, tenants are protected from rules that were never disclosed to them at lease signing, that apply unfairly, that are vague, or that appear designed to help a landlord avoid its own obligations. If a landlord attempts to enforce a post-move-in rule without providing 30 days' notice, or if the rule amounts to a substantial change to the rental agreement, a tenant may have grounds to contest its enforceability. Tenants who believe a rule violates these standards can document the issue, consult a local tenant-rights organization, or raise the provision as a defense in any related legal proceeding.
