Landlord
Landlord's Right To Enter:
Study your lease carefully to determine the circumstances under which the landlord may enter your home. Unless the lease agreement says the landlord can enter your apartment or house, she/he has NO right to do so, except in emergencies and for routine inspections or repairs and, preferably, when you are provided advance notice. In every residential lease (oral or Written),a tenant has an implied right to peaceable, quiet enjoyment of the premises. A tenant also has a right of privacy in her/he own home.
You may want to have your own keyed lock on the door to the apartment or house. If you want your own keyed lock, be sure you provide for this in your lease or obtain written permission from your landlord. Also, a dwelling must be equipped with a keyless bolting device on each exterior door of the dwelling without necessity of request by the tenant. This will prevent improper entries while you are home. see "Locks and Security Devices."
