What a property is worth depends on what it is allowed to become. Most owners never find out.
Land use
New York divides its land into zoning districts — R, C, and M. An R5 residential district permits medium-density housing at a modest floor area ratio. A C6-4 district in Midtown permits towers.
The value is usually in what nobody checked:
- Additional floor area through a zoning lot merger.
- Unused air rights on the lot or next door.
- Mixed-use conversions the current use group forecloses.
Building use
Every structure in New York carries a Certificate of Occupancy that states what it is legally for. Changing that use is rarely a paperwork exercise.
Converting a warehouse to a hotel means egress modifications under the 2022 Building Code, fire protection upgrades under the Fire Code, accessibility updates under ADA and the Construction Codes, and energy compliance under the Energy Code. It also means the Department of Buildings and the Department of City Planning, which do not always want the same things.
The Zoning Resolution
First adopted in 1916 and comprehensively rewritten in 1961, the Zoning Resolution governs use, development, and transformation of land. It defines permitted use groups, bulk regulations for height and setback and lot coverage, floor area ratio limits, parking and loading requirements, and special purpose districts such as SoHo and Hudson Yards.
City of Yes for Housing Opportunity, approved in 2025, is the largest change to it in a generation.
What goes wrong
Assuming a permitted use without verifying it. A buyer assembles lots for a school and discovers the site is zoned for manufacturing.
Unpermitted conversions inherited at closing.
Incomplete permit documentation.
Air rights nobody transferred.
How we work
Preliminary assessment. Then a zoning and land use feasibility study covering FAR increases, air rights transfers, and lot mergers. Then a code and building use review against the Building Code, Energy Code, Noise Code, Fire Code, MDL, and ADA. Then a strategy — which may include a CCD1 or ZRD1 filed before the objection rather than after. Then coordination with DOB, DCP, and FDNY.
Where the leverage is
Vertical expansion through acquired air rights and a zoning lot merger. Creative but defensible use classification. Preemptive reconsideration filings that validate an unusual design before it is priced. Sustainability used as a zoning strategy, where green roofs and solar buy height and reduce parking minimums. Adaptive reuse of buildings whose legacy codes — 1938, 1968 — carry grandfathering worth preserving. And, across a portfolio, consolidating floor area across parcels.
You design the vision. We make it buildable.
