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 has NO right to do so, except in emergencies and for routine inspections or repairs and, preferably, when you are given 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 own home.
