Your landlord can enter your apartment for a valid reason, such as to make repairs, and must give you at least 24 hours’ written notice. They must give you the time and reason for entry in this notice. Unless you agree to waive it or unless they are entering for an emergency reason. Your landlord can enter your apartment between 8 a.m. and 9 p.m. if it’s not an emergency unless you agree to another time outside this window. If your landlord does not give you written notice in person, they must tape it to your door or put it in your mailbox three days ahead of time.
