M1-6D Zoning Residential Use
As-of-Right Residential Use
Residential use in M1-6D is an As-of-Right condition, as long as there the property had no building with over 40,000 square feet as of April 25, 2011.
Residential Use Certification
In M1-6D, if there was an existing building with 40,000 square feet or more on the lot as of April 25, 2011, the property may qualify for residential use with the proper certification from the Department of City Planning.

M1-6D Zoning Regulations
As an architect I study property development and zoning, but New York City Zoning is very complicated. This article is only meant to review basic Zoning Codes as a general introduction. This analysis does not assume to cover every possible issue, but merely to provide a general overview of the zoning codes. This post is not a substitution for the NYC Zoning Resolution or any other applicable Codes or Regulations.
