My question involves landlord-tenant law in the State of: New York - NYC, to be exact.

I recently found out that the room I rent is part of a rent-controlled converted 3-bedroom apartment (it's traditionally a 2-bedroom, but the dining room was converted into a 3rd bedroom). The landlord (the sole leaseholder) is one occupant & then there is the 2nd tenant- me, & the 3rd tenant- other roommate.

I came across a misplaced rent invoice that the management company sent the leaseholder (fyi: I did not illegally open his mail, the invoice was laying on a coffee table in the living room)- the amount of rent the 3rd tenant & I pay totals out to the amount of rent that is due on the apartment. The reason I know it's a rent-controlled apartment is because the leaseholder has stated it a couple of times & in this neighborhood it's widely known that several of the apartments in this building are rent-controlled.

The amount of rent we pay includes all utilities, so after estimating rent & utilities & the amount of rent given to him, he's pretty much only coming out of pocket for the utilities (which are only electricity, cable & internet- heat & hot water are provided by the building).

Is this legal? What can I do (I'm almost sure I'll be told to move out if I don't want to get suckered anymore )

Thanks
