(a) For standard lots In the districts indicated, the maximum residential lot coverage for interior lots or through lots shall be 80 percent and the maximum residential lot coverage for corner lots shall be 100 percent.
(b) For eligible sites In the districts indicated, for zoning lots with buildings utilizing the eligible site provisions of Section 23-434 (Height and setback modifications for eligible sites), the maximum residential lot coverage of the entire site shall be:
(1) 65 percent on zoning lots with a lot area of 30,000 square feet or more that are not large sites; and
(2) 50 percent on large sites. Individual corner lot, interior lot, or through lot portions may exceed such overall maximum, provided they do not exceed the respective maximums that would apply to zoning lots that are not utilizing the eligible site provisions.
Full Breakdown
New York City Zoning Resolution § 23-362 sets the maximum lot coverage for residential buildings in R6 through R12 districts. For standard lots, interior and through lots max out at 80 percent lot coverage while corner lots can reach 100 percent. Projects using the "eligible site" bulk modifications of § 23-434 (large modern apartment buildings on bigger parcels) are capped lower: 65 percent coverage on zoning lots of 30,000 square feet or more that are not large sites, and 50 percent on large sites; individual corner, interior, or through-lot portions within such a site may exceed the overall cap as long as they stay within the limits that would otherwise apply to that lot type.
Companion section § 23-361 governs the lower-density R1 through R5 districts, where one- and two-family homes are held to interior-lot coverage figures in the 40-to-60-percent range depending on the district, with corner lots consistently capped at 80 percent; multiple-dwelling buildings in those same districts get 80 percent on interior/through lots and 100 percent on corner lots, dropping to an overall 50 percent on "large sites" using § 23-425 height and setback modifications. Section 23-363 layers on exceptions: shallow zoning lots eligible for the rear-yard modifications of § 23-342 or § 23-343 get up to one extra percentage point of coverage for every five feet the lot is shallower than 95 feet (interior lots) or 190 feet (through lots), capped at 90 percent overall; and any interior or through lot, or portion of one, within 100 feet of a street corner where two street lines meet at 135 degrees or less, or that fronts the short dimension of its block, may be covered up to 100 percent within that 100-foot band.
The Zoning Resolution's Article I definition of "lot coverage" (last amended 3/22/2016) is the area of a zoning lot that, viewed from directly above, would be covered by a building or any part of one; open-space-qualifying roof area, and terraces, balconies, breezeways or porches not counted in floor area, are excluded from the calculation, though the underside of a projecting balcony counts if it does not project from the building face.
Violations & Fines
The Department of Buildings will not approve construction documents or issue a Certificate of Occupancy for a building that exceeds the applicable lot coverage maximum. Buildings under construction found to exceed the cap are subject to a stop-work order and an Environmental Control Board zoning violation, with the excess floor area required to be removed or legalized before work can resume. A property owner who needs relief from the numeric cap must apply to the Board of Standards and Appeals for a variance under ZR Article VII, Chapter 2, showing the site's unique physical conditions prevent reasonable use within the as-of-right limit.
