C6-6.5 Zoning District — New York City
C6-6.5 is a high-density Restricted Central Commercial District (NYC Zoning Resolution § 11-122) in New York City.
C6-6.5 is a high-density Restricted Central Commercial District (NYC Zoning Resolution § 11-122) in New York City. It allows commercial uses, and generally also housing under the rules of a residential-equivalent district. Under the as of right — narrow street rules, the maximum residential FAR is 10 and the maximum commercial FAR is 12. 23 tax lots citywide carry C6-6.5 as their primary zoning designation.
This is one of the smallest designations in this set, mapped across just 23 tax lots, and its stock is also the most postwar: a median construction year of 1961 and only 45% of buildings predating 1940 — the lowest prewar share here. What stands is tall, at a median of 23 stories with 77% of buildings rising above 6 floors, on lots running to a median of 16,318 square feet and a 90th percentile of 80,333.
What actually stands in this district
This designation covers only 23 tax lots citywide in the records — among the smallest footprints profiled on these pages — so every figure below describes a genuinely small, specific sample rather than a broad citywide pattern. What sits on those 23 lots is also the most modern stock in this set: a median construction year of 1961, squarely inside the 1945-to-1975 building boom, and just 45% of recorded buildings predate 1940 — the lowest prewar share recorded anywhere in this batch.
Buildings here reach a median of 23 stories, the tallest median in this set, with 77% of the recorded stock rising above 6 floors. Lots run large to match: a median of 16,318 square feet, with a 90th percentile of 80,333 — the widest recorded lot spread in this batch, describing a handful of large-footprint towers rather than a uniform block pattern spread over many small parcels.
Beyond its 1961 median, the age record shows 23% of buildings from the 1945-to-1975 boom itself, and just 5% built since 2000 — construction here has slowed since its postwar peak rather than continued into recent decades. Office buildings lead the recorded building classes at 26%, with condominiums at 22% and elevator apartment buildings at 17%, a mix that matches the tall, tower-scale lot fabric described above.
Residential use covers 43% of these lots, with 1,365 units recorded on them. On development capacity, 39% of lots show floor area below their allowance, but the median residual is 0 — no meaningful recorded gap on a typical lot here, consistent with a stock already built to tower scale. None of the 23 lots, 0%, fall inside the mapped federal flood zone on the current map, which describes the map's current boundary rather than a flood history for these parcels.
Every figure here should be read against the designation's small size: 23 tax lots is a specific, countable set rather than a broad citywide sample, and a single large parcel can move a share meaningfully more than it would in a designation covering hundreds of lots. Within that caveat, the file describes a modern, tall, large-lot stock built mostly during or after the postwar boom, with little recorded headroom left and no recorded flood exposure on the current map. The rules tables above carry the governing figures for any of these 23 lots individually, each with its own citation, rather than one blended figure for the designation as a whole.

About commercial districts
Commercial districts allow retail, office, and service uses, and most also allow housing under the rules of a residential-equivalent district. Commercial bulk is governed by § 33- of the NYC Zoning Resolution.
Contextual districts pair their floor-area ceilings with prescribed base and maximum building heights so new buildings mirror existing neighborhood form; non-contextual districts govern the envelope through more general height and setback rules, such as sky exposure planes. Commercial districts also allow residences under the rules of a residential-equivalent district, while manufacturing districts generally exclude new residences. Overlays and special purpose districts can modify any of this on a specific lot.
