I'd like to convert a one family brownstone into a two family. Any advice?
My sister owns an one family brownstone in Park Slope and, in the interest of saving money and being close but separate, she would like to sell me the garden and basement floors. I would then convert them into an apartment and she would keep the top three floors. Has anyone done this?

Hi, We just converted my brownstone from a one family to a two family: Got the C of O last month. We used Scott Schnall for the expediting. 718-875-2036

We’ve done a number of these in Park Slope and other areas in Brooklyn, and they can be relatively straight forward. I’d be happy to discuss the related issues with you. Jim Hill, RA, LEED AP Urban PIoneering Architecture

We work on C of O’s frequently, so yes many people are actively converting.

It is done all the time. At a min., just change the C of O, add a kitchen and make sure the proper fire rated separations are installed.
