I'm attempting to calculate the Gross Floor Area of my building (a small coop). What is not clear (to me) is whether outdoor, uncovered, roof decks are used in the calculation (description below).
GFA is one metric used to determine if a building is classified as "covered" under Local Law 97, which mandates reductions in greenhouse gas emissions starting this year (but getting serious in 2030).
Per 1-RCNY-103-06: "Gross floor area is the total number of square feet measured between the
exterior surfaces of the enclosing fixed walls. It includes vent shafts, elevator shafts, flues, pipe shafts,
vertical ducts, stairwells, light wells, basement space, mechanical/electrical rooms, and interior parking.
It excludes unroofed courtyards and unroofed light wells. For atria, gross floor area only includes the
area of atrium floors. For tenant spaces, interior demising walls should be measured to the centerline of
the wall."
Another definition I found says balconies should be included. Nothing I've found either includes or excludes roof decks.
WITHOUT including our roof decks my building is likely just under the 25,000 gross sqft threshold specified in LL97. Including them puts us over. This has serious implications for the finances of our coop in the near future.
Gross floor area for Coop is listed on Notice of Property Value for your property in NYC Dof.
Use can use address to search for Borough Block Lot. Also you could use digital tax map to locate your property.
Look for the Notice of Property Value for January of this year as only the January notice has square footage on it.
Then you can look for your building in Dob Now or Building Information System to check for size of building.
LL 97 should not count the area on the roof.
Their is also an online tool called Energy Snapshot the will have basic information on your building such as square footage and energy usage.
