New York City has many zoning districts and subdistricts, each with its own rules and regulations governing property development within the district. R7-2 is one example of a residential zoning district in NYC.
R7-2 is a medium-density Residential Zoning District in New York City. You can find R7-2 Zoning Districts in Manhattan, The Bronx, Brooklyn, and Queens.
I am Jorge Fontan, an architect in New York and owner of Vinculum Architecture, a Manhattan-based architecture firm. At Vinculum, we work on a variety of project types, from property and zoning analysis to complete building designs for new developments. In this article, I will review some of the basics of the New York City Zoning District R7-2.
R7-2 Zoning
Multiple New York City Zoning Districts, such as R7-2, have fixed height limits and mandatory setbacks as options or alternative regulations for Height Factor zoning. The City of Yes significantly modified the rules under the New York City Zoning for Housing Opportunity amendment. This article reflects those modifications.
Qualifying Affordable Housing Option
Developers planning projects in an R7-2 Zoning District have the option to construct a strictly market-rate building or to incorporate Qualifying Affordable Housing units. While different zoning regulations and bulk rules apply to each approach, the inclusion of affordable housing allows for a larger overall development, including an increased Floor Area Ratio (FAR) and a higher maximum building height. There are also modified regulations for Qualifying Senior Housing.
R7-2 Zoning Commercial Overlay
When a residential district includes a commercial overlay (e.g., C1 or C2), the zoning permits local retail and services within the residential district.
This designation provides flexibility: developers can construct a purely commercial building, a residential building, or a mixed-use building combining both functions. It is crucial to note that the zoning regulations—particularly regarding Floor Area Ratio (FAR) and building bulk — vary significantly between the commercial and residential portions of a development.
R7-2 Zoning & Community Facility Use
The R7-2 Zoning District is primarily residential, but you can develop community facility uses (such as schools, medical facilities, and certain non-profits) as-of-right.
Key considerations for the development of a Community Facility in an R7-2 zone include:
- Different Regulations: When you develop a site with community facility use, the specific bulk regulations (including Floor Area Ratio and height limits) may differ from those for standard residential buildings.
- Mixed-Use Options: Developers may also construct a mixed-use building that combines both residential and community facility components.
R7-2 Zoning Regulation Basics
Lot Size:
- Minimum Lot width =18 Feet
- Minimum Lot Area = 1,700 Sq Ft
For Single or Two Family Detached Developments the Lot Size is:
- Minimum Lot Width = 25 Feet
- Minimum Lot Area = 2,375 sq ft
Floor Area Ratio (FAR) on a Narrow Street:
- FAR = 3.44
- Qualifying Affordable Housing FAR = 5.01
Floor Area Ratio (FAR) on a Wide Street:
- FAR = 4
- Qualifying Affordable Housing FAR = 5.01
Yards for Zero Lot Line or Detached Buildings:
- Corner Lot: No Yards Required
- Interior Lot = 20 foot minimum rear yard required below a height of 75 feet
- Interior Lot = 30 foot minimum rear yard required above a height of 75 feet
Yards for attached and Semi-Detached Buildings:
- Corner Lot: No Yards Required
- Interior Lot with a Width Less than 40 feet = 30 foot minimum rear yard required below a height of 75 feet
- Interior Lot with a Width of 40 feet or more = 20 foot minimum rear yard required below a height of 75 feet
- Interior Lot = 30 foot minimum rear yard required above a height of 75 feet
Lot Coverage:
- Corner Lot = 100%
- Interior or Through Lot = 80%
Density Factor
Density Factor (Also known as Dwelling Unit Factor) does not apply to all areas of NYC
- 680
Base Height Wide Street: This indicates a setback is required at these heights.
- Base Height = 40 Minimum / 75 Maximum
- Qualifying Affordable Housing Base Height = 40 Minimum / 85 Maximum
A setback is required in the base height range. Or this can be the maximum height of the building without a setback.
Building Height Wide Street: This is the maximum building height.
- Building Height: = 85 feet
- Qualifying Affordable Housing Building Height: =115 feet
Base Height Narrow Street: This indicates a setback is required at these heights.
- Base Height = 40 Minimum / 65 Maximum
- Qualifying Affordable Housing Base Height = 40 Minimum / 85 Maximum
A setback is required in the base height range. Or this can be the maximum height of the building without a setback.
Building Height Narrow Street: This is the maximum building height.
- Building Height: = 75 feet
- Qualifying Affordable Housing Building Height: = 105 feet
Height Factor Option for R7-2 Zoning
In R7-2 Districts, developers can use Height Factor regulations as an alternative to determine a building’s permitted Floor Area Ratio (FAR) and required Open Space Ratio (OSR) based on its height. The Sky Exposure Plane, an imaginary sloping plane that the building mass cannot penetrate, determines setback and height limitations for a Height Factor Building. Under these rules, as building height increases under this option, the following occurs:
- Variable FAR: The maximum FAR range increases based on the number of stories.
- Proportional Open Space: To build taller, more open space must be provided on the lot; the OSR ranges.
- Building Form: This encourages tall and skinny buildings on large lots.
Sliver Law
The Sliver Law is a New York City zoning regulation that limits the height of buildings on lots less than 45 feet wide to prevent the development of excessively tall, slender structures. While the law does not apply to buildings in districts that follow the height limit guidelines, it remains applicable in R7-2 for developments using Height Factor and Sky Exposure Plane options.
Parking in R7-2
The new City of Yes for Housing Opportunity zoning changes have now drastically reduced parking requirements in New York City. There are currently no parking requirements for the Inner Transit Zone, and reduced parking requirements in the Outer Transit Zone, which can be waived under certain conditions.
R7 Zoning Districts:
Commercial Districts with R7-2 Residential Equivalents:
Most commercial districts in New York City have a Residential Equivalent. This designation means that you have the option for developing residential use in the given commercial district and that regulations of the applicable Residential Equivalent would govern the residential portion of the building. The following are commercial zoning districts with an R7-2 Residential Equivalent:
- C1-6
- C2-6
- C4-4
- C4-5
- C6-1
We have another post with a list of all Residential Equivalents in Commercial Districts if you want to see more on the subject.
