M1-4D Zoning Residential Use

The M1-4D Zoning District is a sub-district of M1 Zoning in NYC.  M1 is a Light Manufacturing Zoning District having manufacturing, commercial, and community facility uses. Normally you cannot develop residential buildings in M districts. M1-4D is very similar to M1-4 zoning, except that you may be able to develop residential use in an M1-4D zoning district with proper authorization from the Department of City Planning.


Qualifying for Residential Use in M1-4D Zoning

You may be able to build a residential building or house in a M1D zoning district, but there are restrictions. The individual lot must satisfy some criteria, such as reaching thresholds for existing residential use on the surrounding properties. The existing use of the lot in question will affect this application.

A residential development in any M1D Zoning District will require approval from the Department of City Planning which is a lengthy and involved process. As long as the property qualifies and the proposed development is in adherence with all other zoning codes, you will be able to proceed with the development.

If you a proposing a development in M1-4D that does not have any residential use, you will follow the zoning regulations for M1-4 Zoning. Developments for residential buildings will have different regulations.

Hotel Zoning in M1-4D Zoning

Hotels are no longer As of Right in M1-4 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.


M1-4D 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.
