R2 Zoning NYC

R2 Zoning NYC Single Family Residential District

(Last Updated On: June 3, 2019)

R2 Zoning is a low density residential zoning district in NYC. You can only build single family detached homes in R2 zoning districts. R2 also has subdistricts R2A and R2X which are similar in nature but vary on certain specific regulations.

 

R2 Zoning

The R2 zoning district, which permits the construction of detached single family homes, can be found in The Bronx, Brooklyn, Queens, and Staten Island.

This post will focus on R2 Zoning and not the R2A or R2X subdistricts. You may however want to see the links below to learn more about these subdistricts.

NYC R2 Zoning Regulations

What is R2 Zoning?

In NYC R2 is a low density zoning district in NYC where one can build single family detached residences. A detached house is one that has yards on all sides of the house and is not attached to the neighbor’s house. Therefore row houses, attached houses, two family houses, and multi family buildings are prohibited in R2 districts. You can find R2 zoning in areas with primarily single family homes such as Riverdale, Bronx or parts of Queens and Staten Island. These are examples of lower density residential areas with only single family homes.

R2 Zoning Community Facility

R2 Zoning is a residential zoning district, but Community Facility Zoning uses are allowed in R2 zones. In the instance of a community facility, the zoning calculations may be different as community facilities can have alternate requirements. For example the FAR for a community facility will typically be different than the residential FAR.

 

NYC R2 Zoning Specifications

There are 3 types of R2 Zoning districts: R2, R2A, and R2X. The specifications below are for regular R2 zoning.

Minimum Lot Size: Lot Area & Lot Width

Lot Size:

You can only build single family detached homes in R2 zoning. A Detached house has yards on all sides and does not touch any other buildings or houses.

Minimum Lot width =40 Feet

Minimum Lot Area = 3,800 Sq Ft

R2 Floor Area Ratio (F.A.R.):

Floor Area Ratio determines the floor area that can be built on the property.

FAR = .5

Density Factor or Dwelling Unit Factor (DU) for R2

1,900

R2 Building Heights: 

Sky Exposure Plane starting at 25 Feet. This means there is not a specific maximum height but an imaginary plane that dictates the height requirements.

Yard Requirements for R2

Front Yard = 15 Feet minimum

Rear Yard = 30 Feet

Side Yards = 13 Feet of side yards combined with the smaller of the two yards being 5 feet minimum. That is to say the minimum side yard dimension is 5 but they must add up to 13.

Parking

1 Parking Space is required per house on the site open or enclosed.

 

R2 Zoning Example, Building a New Home

Here is a basic zoning analysis for a R2 single family home. We will be using basic R2 regulations for this example. Zoning will determine the maximum size, square footage, location of house on the property, yard requirements, and many other variables.

How big of a house can I build in R2 Zoning?

Lets assume we are dealing with a property that is 40 feet wide and 100 feet deep and is on an interior lot. An interior lot is located within a block with neighboring properties on 3 sides (through lots and corner lots for have different rules). We have another blog post if you want to learn more about the difference between interior, through, and corner lots.

Floor Area Ratio (FAR) in R2 Zoning

The floor area ratio of a property is a zoning term that governs how many square feet you can build on a given property. The larger the property the more square footage you can get and in turn the smaller the property the less square footage you can build. You multiply the property square footage by the floor area ratio to get the maximum square footage for your house.

The Floor area ratio in an R2 Zoning district is .5

If the lot square footage is 40 x 100 = 4,000 square feet

Lot Square Footage X Floor Area Ratio  = Maximum square footage of house

4,000 square feet X  .5  =  2,000 square feet (Maximum House size)

R2 Zoning Conclusion 

In this example, we can build a house that is 2,000 square feet or less (2,000 is the maximum house size). There are certain zoning deductions you can get that change from zone to zone, for example a cellar does not count for FAR but a basement does. We will not go into that level of detail here but sometimes you can discount certain parts of the house like a boiler room. If you have a cellar it does not count for the zoning square footage but a basement would. Please be aware there is a difference between cellar and basement. A basement does count for zoning square footage.

So we now know we can build a 2,000 square foot house on a 4,000 square foot R2 lot.

In the next diagram, you can see the buildable area and the house footprint is a little smaller. Although the house can be located anywhere in the buildable area, I located it at the front yard 15 foot line. I left a large rear yard and we made one of the side yards a little bigger by aligning the side of the house with the 8 foot side yard because I wanted a little extra on the other side yard.

NYC Zoning

As an architect, I study zoning very closely. NYC Zoning is complicated and quite involved. In this article, we reviewed some of the basic Zoning Codes with regards to residential zoning district R2. This analysis does not assume to cover every possible issue and condition, but provide a general overview. This post does not substitute the NYC Zoning Resolution. You can learn more from the Department of City Planning R2 Regulations.

    Hi,Mr.Jorge Fontan, I have questions regarding R2 zoning for a corner lot in Staten Island. I know I can build max 2000sf. Does basement count it as living sf ? That is about 4 ft above ground.

    Will they allow you to split a 60×100 corner plot into 2 plots? (R2A)

    The current house is a 20×60 and is 3-4 feet from the neighbors plot

    Could I split into:
    30×100 & 30×100?

    Hi Mr Fontan,

    This was very helpful. I am currently looking at a 40×100 R2 Zoning corner lot with an existing home of 22×36 sitting on it and a separate garage in the rear yard. Given that this is a corner property, and that corner lots do not require rear yards. What is the maximum square footage one can build on such a lot?

    Thanks,
    Ahmed

    I currently own two two-family units, divided by a concrete fire wall, under a single roof and over a single basement, two separate addresses but one building, one block, one lot, tax classification C3 (four-family walk up), R2 zoning.

    I have no C of O for either side (building predates 1938), but have been issued Letters of No Objection to operate as two two family buildings.

    Would it be possible in my case to apply for an apportionment, and PW1 Subdivision, and sell each side independently of each other, as separate duplexes, or would the R2 zoning
    prohibit this?

    Many thanks for your insight, and best…
