Does the Act apply to my rental units?  The Act applies to the rental of dwelling units.  Therefore, generally speaking, if you rent a residential dwelling, the Act applies to you, but there are some exclusions.  The specific exclusions from the Act are found in A.R.S. Section 33-1308. 

Does the Act apply to a landlord's on-site manager?  Maybe. On-site managers are specifically excluded from the scope of the Act.
