My landlord just walked in my home without letting me or anyone in my household know that he was coming. He knocked, then immediately stuck his key in the door and walked right on in on the whole family. What can I do about this?

You call Community advocate for any landlord /tenant issues ask for housing information

Your landlord needs to give you a 24 hour notice . He is not suppose to let himself in your apartment .

When a landlord needs access to an apartment he needs to give a 24-hour notice unless it's like a mergency like maybe water damage in apartment or something like that but otherwise 24-hour notice

Check your lease agreement, if it is the lease that they can enter without prior knowledge than it's not illegal. If not contact the Neighborhood Services Department.

I would call the police and make a report because that's against the law
