The Arizona Residential Landlord and Tenant Act, A.R.S. §§ 33-1301 to 33-1381, applies to you if you are renting a residential dwelling unit such as a house, condominium, or apartment. There is a separate law, the Arizona Mobile Home Parks Residential Landlord and Tenant Act that applies if you are renting a mobile home.
As a landlord or a tenant it is important to keep in mind that the Landlord and Tenant Act governs the landlord tenant relationship and that in some important areas its provisions may override even the parties' written agreement contained in the lease. If you've got a question about the Act or how it may apply to your situation, you should consult with an Arizona landlord tenant attorney.
