    Hi, would you be able to build an apartment building in an M1-1 zoning 100×100 lot? This property is in the Bronx, NY. There is currently a single family home on the lot and the rest is just used for parking trucks etc. Can the existing single family house be taken down? Thank you very much for any help you can give me.

        Can you change an existing commercial building in Brooklyn that zoned as M1-1D into a residential building? If you can, does it need a variance?
