R2 Zoning Regulations
The New York City Zoning Resolution is complicated and quite in depth. In this article we will review some basic Zoning Codes with regards to residential zoning district R2. This analysis does not assume to cover every possible issue, but provide a general overview of the zoning codes.
R2 Zoning Community Facility
R2 Zoning is a residential zone but Community Facility 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.
What is R2 Zoning?
R2 is a zoning district in NYC that only allows 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. Row houses, attached houses, townhouses and two family houses and multi family buildings are prohibited in R2 districts. You can find R2 zoning in areas like Riverdale Bronx or parts of Queens and Staten Island. These are lower density residential areas with single family homes.
There are 3 types of R2 Zoning districts: R2, R2A, and R2X.
Zoning R2 Districts
Lot Width Minimum – 40′
Lot Area Minimum – 3,800 square feet
FAR – .5
1 Parking Space Required On Site open or enclosed.
R2 Zoning Example, Building a New Home
Here is a basic zoning analysis for an 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?
Floor Area Ratio
Lets assume we are dealing with a property that is 40 feet wide and 100 feet deep and located in the middle of the block with neighboring properties on 3 sides (corner lots have different rules).
Floor Area Ratio
The floor area ratio of a property is a zoning term that governs how many square feet you can build on a property. You multiply the property square footage by the floor area ratio and then you get the maximum square footage allowed for your house.
The Floor area ratio in an R2 Zoning district is .5
The lot square footage is 40 x 100 = 4,000
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)
In this example we can build a house that is 2,000 square feet or less (2,000 is the maximum). There are certain deductions you can get that change from zone to zone we will not go into that level of detail here but sometime you can discount certain parts of the house like a boiler room or garage. If you have a cellar it does not count for the zoning square footage. 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.
R2 Zoning NYC Yard Requirements.
In an R2 zone you will be required to have yards on all sides of the property.
The front yard in an R2 district is 15 feet minimum.
The rear yard in R2 is 30 feet minimum.
Corner lots do not require rear yards. Instead they have 2 side yards and 2 front yards.
You need 2 side yards, the smallest a side yard in R2 is 5 feet but the two side yards combined must be at least 13 feet. So lets assume 1 side yard of 5 feet and 1 side yard of 8 feet for a combined 13 feet of side yard.
Below is a diagram showing the required yards and where we can put our new home. We can build the house anywhere within the shaded area.
We now know where we can build our house and how big it can be. Since our house can be a maximum of 2,000 square feet lets make it 2 stories of 1,000 square feet each. Which we can locate anywhere in the buildable area. I am going to make the house 25 feet by 40 feet 1,000 square feet per story and two stories for a 2,000 square foot house.
In this last diagram you can see the buildable area previously established 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 in this case which would give 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.
