I believe DC law states that the terms of the original lease remain when you go month to month except for lawful rent increases. But what I don’t know is if that means that the term in your original lease about the 90 days notice remained in place or if the “except for lawful rent increases,” provision is covered within that, meaning they only have to give you 30 days notice. They certainly have to give you some notice, I just don’t know if it’s 60 days.
