A landlord may inspect a rental unit if?

A landlord in Arizona is generally required to provide at least two days' written notice before entering a rental unit for inspection or maintenance. This two-day notice period strikes a balance between the landlord's right to manage and maintain the property and the tenant's right to privacy in their home. The law specifies reasonable notice to ensure that tenants have sufficient time to prepare for the inspection while allowing landlords to fulfill their responsibilities.

In contrast, providing one day's notice may not give the tenant adequate time to prepare, which can lead to misunderstandings or disputes. On the other hand, three days’ notice exceeds what is typically required, potentially causing unnecessary delays in the landlord's ability to address important matters. No notice, while sometimes permissible in emergencies, does not respect the tenant's right to privacy. This makes two days’ written notice the appropriate choice for ensuring compliance with Arizona's landlord-tenant laws.
