R6 Zoning NYC Residential Development

by | Last updated May 31, 2020 | Published on Apr 10, 2016 | NYC Zoning

R6 Zoning in NYC is a residential zoning district with small multifamily apartment buildings and single or two family homes. R6 is medium density non contextual zoning.  In R6 you have a choice of Height Factor Zoning or Quality Housing Program. It is the only residential zoning district in every New York City Borough: Manhattan, The Bronx, Brooklyn, Queens, and Staten Island.

This post is going to be discussing the basics of R6 Zoning in New York City. As Architects in NYC, we get a large number of inquires at our office about R6 Zoning, lets look at some of the issues concerning properties zoned R6.

 

R6 Zoning Districts

Basic R6 District

  • R6
    • Option 1: R6 Quality Housing Program
    • Option 2: R6 Height Factor

R6 Contextual Districts

Commercial Zoning With Residential Equivalent R6 Zoning

Most Commercial Zoning districts allow for residential use. Below are Commercial zones with R6 Residential Equivalents.

 

R6A & R6B Contextual Districts:

R6A and R6B are contextual zoning districts and would have some different regulations than basic R6 Zoning. In this article, we are only going to be addressing basic R6 zoning, not the subdistricts.

 

R6 Zoning NYC Residential District

New York City is has different zoning districts. The purpose of these districts is to restrict what people build based on the location. A zoning district that begins with ‘R’ is a residential district. They go from R1 through R10. The higher the number the larger the building you can build. R6 is most commonly in Brooklyn, Queens, and the Bronx. There are a few areas in Manhattan and Staten Island that are zoned R6.

 

What is R6 Zoning?

R6 Zoning is a medium density residential zoning district. It has multifamily buildings that can range from walk up townhouses to taller apartment buildings. In R6 zones you have two options for zoning rules. You can use Height Factor Zoning or Quality Housing Program.

 

R6 Quality Housing Program

The Quality Housing Program is most likely the option one would go with in R6 zones and in fact is required in R6A and R6B zones. The quality housing program promotes shorter wider buildings. This is not to be confused with the Inclusionary Housing Program for affordable housing. The quality housing program typically will result in a larger building of a higher quality. There are more zoning floor area deductions in quality housing that would give you a boost to your building size.

 

R6 Zoning Community Facility

R6 Zoning is a residential zone but Community Facility uses are also allowed in R6. In the instance of a community facility the zoning calculations would be different. One can also build a mixed use building with both community facility and residential use.

 

R6 Zoning Commercial Overlay

Sometimes residential districts have commercial overlays. this means the zone is primarily residential but commercial use is allowed instead or as a mixed use building. Here is a link to an article we wrote on Commercial Overlays.

 

R6 Incusionary Housing Program

Always check if your property is subject to requirements of the Inclusionary Housing Zoning. These are districts that have either optional and sometimes mandatory requirements for low income housing. In these areas you provide a percentage of your floor area for affordable units. There may be zoning penalties if you choose not to provide it, and zoning bonuses if you do.

R6 Zoning Example Quality Housing Program Residential Use

R6 Zoning Narrow Street Example = FAR 2.2

Here we will see a few of the zoning issues that, as architects, we look into when evaluating the zoning of a property for a Multi Family Residential Development. Basically these are the steps an architect takes in determining the general shape, size, use, of a property. Additionally we look at more specific issues such as how many residential units you can put in a new residential development. this is based on an R6 district using the Quality Housing Program.

For this example, we will use a property that is 100 feet wide and 100 feet deep in an R6 zoning district. This building will be located on an interior lot in the middle of the block, properties at the corners of a block have different regulations with regards to yard requirements.

Property Line 100 x 100

Property Line 100 x 100

The property we are looking at is 100 feet by 100 feet, that means the property is 10,000 square feet.

100 x 100 = 10,000 square feet

Our first step is to calculate the floor area ration of the building also called FAR.

Floor Area Ratio

Floor area ratio (FAR) is a proportion that determines how many square feet your building can be. The FAR for this property is 2.2 as determined by the NYC Quality Housing Program Zoning Regulations. This means we take the property square footage and multiply it by the FAR to figure out the zoning square footage.

Property Square Footage X FAR = Zoning Square footage

Property Square footage = 10,000

FAR = 2.2

10,000 x 2.2 = 22,000

The zoning on this property allows 22,000 square feet to be built. 22,000 is the maximum required zoning square footage but the actual building can be a little larger after determining areas that do not count for zoning floor area. For the sake of simplicity of this example, we will not be considering those deductions.

We can build a 22,000 square foot building with 32 Apartments on this property. 

 

R6 Zoning Height Factor

Height factor is one set of zoning regulations that promotes building taller skinnier buildings. Height factor does not apply in “contextual districts.” There are proportional requirements governing the height, footprint, and general size of the building. With height factor zoning the taller the building gets the less area it can cover on the site, basically the taller it gets the skinnier it needs to be with more open space on the property. Additionally the taller buildings are allowed a higher floor area.

R6 Height Factor Example:

A 5 story building in an R6 Zone would have a Floor Area Ratio of 2.02 If you went to 14 stories you would be able to use the maximum Floor Area Ratio of 2.43. The floor area changes based on the number of stories and is proportional to the area the building can cover on the lot.

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 R6. 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. If you truly want to understand the zoning of a property you can get an Architectural Zoning Analysis.

 


Thank You for Reading our Blog Post on R6 Zoning NYC

This is a really basic example of some of the calculations we do when performing a zoning analysis. There are many more variables and considerations to take into account. The NYC zoning code is thousands of pages. If you are interested in discussing zoning with an architect please feel free to contact us dierctly.

  • Ishmael Hall says:

    Hi Jorge,

    I own a 2 family in an R6 zone. The CO from 1944 also lists it as a 2 family dwelling. It is unclear however if they are including the basement as apart of the dwelling as the side is cut off. I want to convert this property to a 3 family dwelling. What must I do/What should be my first steps?

    Thank you

  • Firyal Farage Jabbie says:

    My husband and I are looking into purchasing a lot in the Bronx, zoning is R6 and the address is 2259 Bassford Ave Bronx. The lot size is 24ft x 41ft with an approved plan for four stories. At first the owner intended to build a four stories with the first and second floor used as a church and the top two floors as two bedroom apartment each. We intended to keep the first floor as a community center and utilize the top three floor as apartments.
    We went to DOB yesterday and we saw a plan examiner and she said if the lot existed prior 1963 then it may qualify as a small zoning lot . what can we do on the lot?

  • Tim says:

    Hi,
    I was wondering if it’s possible to build a 2-3 family house or mixed used property on a 40*40 lot in Brooklyn. However, it’s not on a street line but instead in a “allyway”.

  • Courtney Osborn says:

    Wow, I frequently visit your website for helpful information regarding NYC Zoning since it is more complicated than other zoning districts. I was assuming you would provide helpful information. I was mistaken.

    Thank you for insulting me. Happy Holidays

    • Courtney
      I am trying to help you. You are going to get sued if you make a mistake. What if someone buys a property based on an erroneous zoning analysis you provide. That will be terrible for them and bad for you. Have you not thought about that? I am trying to talk some sense into you. You are in over your head and me telling you that is not an insult it is good advice. So I pose my objection again:

      Were you paid to do a zoning analysis that you are not capable of doing? Why did you accept the money if you do not know how to do it? I think some people would call that fraud. You literally put on your website that you are “Real Estate Due Diligence Experts” Why are you accepting money to do work you do not know how to do? You are not an expert on New York City zoning, you just aren’t. So I would love for you to explain why you think it is ok for you to take money to do a Zoning Analysis when you do not know how to do it.

  • Courtney Osborn says:

    I am doing a zoning analysis on a property in the Bronx. It is zoned R6. How do I determine if the property is utilizing the Quality Housing program or the Height Factor? Oasis mentioned the allowable FAR is 2.43 with a 6 story building.

    • Courtney,
      I see you are with a company claiming to be “Real Estate Due Diligence Experts” yet you are posting a basic Zoning question on my blog (like seriously NYC zoning 101). So when your company says the word “experts” how do you define that term?
      You are obviously not qualified to do that zoning analysis and therefor you should not have taken money to do it. Or did you tell the client first that you do not know how to do their zoning analysis and would need advice from me to complete it?
      Nobody had a blog for me to read to learn how to do this. I actually had to read the zoning code. If you are getting paid to do a zoning analysis you should not need my advice on simple zoning questions. You should know how to do this. You are in over your head.

  • Henry Qin says:

    I have a question about mandatory inclusionary housing. If a property is under MIH, will the value of the property increase or decrease in the future if is up for sale? And if investor wants to buy this property to rebuild more units, are they more willing to buy it or look at other block that can build the same thing but with no MIH restriction? Thanks.

    • I am an architect I do not comment on property value. Nor can I speculate on how another person may alter a building in the future. These are questions for a real estate developer not an architect.

  • Good morning Jorge. i Just ended up on your website this morning, very interesting info thank you.
    I have one question.
    I have a property in Brooklyn in a R6A Zone. the lot size happen to be only 20×75 FAR 3 1,500 SQF lot.
    will i be able to building a 4 or 5 family there if i want?
    thank you

    • Jean-Claude
      No you cannot do Multi family here. 20 x 75 = 1,500 square feet. You will need a minimum of 1,700 square feet in order to do multi family defined as 3 families or more.
      You can do 1 or 2 families.

  • Charles Galliano says:

    Can you legally convert a 1, 2, or 3 family dwelling in an R6 zone into a 4 unit property?

    • Charles, to answer the question about how many units you can put on an R6 property. Determining how many families one can develop on a given property requires more detailed information on the individual property. There are formulas that have to be calculated based on the size of the property that determine the allowable number of families. If you are interested in a zoning analysis, please call our office at (212) 321-0194.

  • Sebastian Bartolotta says:

    I own a 2 family attached home on a 25 by 100 lot 5 feet of the width is shared driveway with another home that is unattached. My question is if I was to purchase the home that is attached to mine giving me a 50 by 100 lot with 5 feet on either side shared with the neighbors leaving me with 2 lots of 20 by 100 what would I be able to build on this lot ? It’s zoned r6 in a transit zone

  • Mike Green says:

    U write that a r6 in other areas are 2.2 FAR ( narrow streets), isn’t it 2.43?

    Thanks for your great clarity

    Hope to use u soon

    • R6 has 2 options for zoning. You can do height factor or you can do Quality Housing Program.
      Height factor has an FAR of 2.43 if you make a building at least 13 stories tall. This is not usually practical especially on smaller lots. If you have a very large lot than it can work.
      Quality Housing Program has an FAR of 2.2 and it goes up to 3.0 within 100 feet of a wide street.
