Rented property is no longer the exclusive domain of the landlord.
The landlord has given possession to the tenant for the duration of the tenancy. If the landlord insists on this he may be guilty of trespassing and in violation of the covenant of quiet enjoyment. This is a situation more to be governed by courtesy and respect for the rights of others than by the law. In Prince George s County landlords are required to give tenants 24 hours written or oral notice of their intent to enter. Entry is allowed only during normal business hours or at a time that has been mutually agreed upon by both landlord and tenant.
