    Can existing 2-family in M1-1 be extended?

  • John says:

    Hi – for a 3 family rowhouse in an M1-1 Zoning that was built in 1900 and currently used as residential, is it correct that such use is grandfathered and permissible? If a fire burned down the building, could a new 3 family rowhouse be built?

    • We would have to verify the legality of the original use. This would require records research into the property to determine if the residential use was a legal, existing condition. Also, we would have to determine how many units were there legally– was it three? was it less? Determining whether or not it is grandfathered requires records research. If you would like us to help you with this, you may contact our office at (212) 321-0194.
