Exactly my situation. In Baltimore City and this was just a couple months ago. We move next week (60 day notice)

Had no idea this was a thing, I wish I could point out the law to our current landlord to further tell them how incompetent they are.

We signed a lease that stated 60 days notice, the lease ran out and we were put on month to month and that’s when all of the “well technically you don’t have a lease agreement so we can do whatever we want” started coming from.
