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. There are criteria to qualify based on the existing and proposed use of the building. This certification can be an involved and lengthy process.


M1-6D Zoning Specifications

If you are proposing a development in M1-6D that does not have any residential use, then you will follow the zoning regulations for M1-6 Zoning. Developments for residential buildings will have different regulations.

For Residential Uses:

M1-6D Floor Area Ratio (FAR)

Floor Area Ratio = 9 for Residential Use Only

Potentially up to 10 FAR for residential may be provided in the case of a mixed use building.

Potentially a FAR of up to 12 may be available with the inclusion of affordable housing.

We have another post you can check out to learn more about Floor Area Ratio Calculations.

Dwelling Unit Factor DU or Density Factor

Dwelling Unit Factor = 680

Rear Yard

Rear Yard = 30 feet


Hotel Zoning in M1-6D Zoning

Hotels are no longer As of Right in M1-6 Zoning. Developing a hotel in an M1 district now requires a special permit. We have another post you can read on the special permit for Hotel Zoning in M1 zoning districts.


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.
