Okay all you NYC-ers out there, I am doing some research on my own but if anyone out there knows the answer please let me know.

I got home tonight and there was a letter from my landlady (who lives downstairs). She is raising the rent by $200 effective JULY FIRST! That's only ten days. Is that legal? Doesn't she have to give us more notice? I'm looking into it but if anyone knows the legal ramblings and such, please let me know.
