Does your Coop have an alteration Agreement policy? The is a legal definition for each type of apt and what a room constitutes under the housing code. I would have to wonder about the legality of sales and listings, misrepresentations of fact, etc. in calling a studio a 1 or 2 bedroom apt. A loft is not an over-sized studio as such. I would hope that no architects are involved because to fail to apply for a new C of O for the unit would be a problem for them, and a renovation that didn't meet code would be as well. But, this also affects the share distribution and valuation as well. IF someone has a 2 bedroom should they be paying higher maintenance than a studio? Given the fact that occupancy regulations are specific as to how many adults, and minors can occupy a space rated as a studio, one, two bedroom etc. the amount of square footage, windows etc. In NYC a room has to have at least one, to be counted as a legal room.
