My question involves landlord-tenant law in the State of: Arizona
I lease an office building. We keep the door locked to control access into our building. The office staff is comprised of four women who feel much safer with the door locked because we have a high volume of undesirable foot traffic in the area. We have a doorbell to let the staff know when someone is here.
My landlord consistently uses his key to access the office for non emergency situations. Often coming in quietly and startling the office staff. He comes in to bring mail, bills or to pick up the rent check. I have addressed this with him before and asked that he not just enter the building because of the effect it has on my staff. He continues to do this at least 2-3 times a month.
We agreed to a simple lease and there is no clause granting him access to the rental property at his whim. I also suspect he is coming into the office after hours for whatever reason, I am not finding anything out of place, but the women sometimes find the toilet lid raised in the morning, which is odd considering it is only women in the office.
I have searched for Tenant Law in Arizona and find most of it applies to Residential. My specific question is, can I legally stop the landlord from entering the building without giving notice in a Commercial lease?
Thank you
