Development sites, buildable area, and the rezoning corridors that matter.
How NYC sites get priced — FAR, assemblage, and residual land value — and where the upside is concentrated right now.
A development market with real momentum
How a development site gets priced
Value flows from buildable area. Multiply lot size by allowable FAR to get buildable square footage, then work backward from the finished project: gross development value, minus construction and soft costs, minus a developer's required profit, equals the residual land value. That residual is what the dirt is worth.
Example: a 5,000 SF lot with a 4.0 FAR yields about 20,000 buildable SF. A rezoning that lifts FAR — or an assemblage that reaches a more efficient size — can change the buildable area, and therefore the land value, dramatically.
Corridors to watch
- Long Island City — the OneLIC rezoning is the marquee opportunity: 54 blocks, ~14,700 units, waterfront density.
- Gowanus — rezoned industrial corridor topping development-ROI watchlists; active assemblage market.
- Williamsburg — rezoned industrial blocks creating ground-up and mixed-use plays.
- Jamaica — transit-rich rezoning corridor with continued density potential.
Answers to common questions
What is a development site worth in NYC?
A development site's value is driven by its buildable square footage — lot size multiplied by the allowable floor area ratio (FAR) — minus the cost to build and a developer's required profit. The residual land value is what's left for the land after construction costs and return. In rezoned corridors, an FAR increase can lift buildable area and value substantially.
Which NYC corridors have the best development upside?
Long Island City stands out: the OneLIC Plan rezoned 54 blocks and enables roughly 14,700 new apartments. Gowanus and Williamsburg's rezoned industrial corridors top development-ROI watchlists and are creating assemblage opportunities, and Jamaica remains an active transit-rich rezoning play. Citywide, about 43,000 units were under construction at the start of the year and developers filed 21M square feet in Q1.
What is FAR and why does it matter?
Floor area ratio (FAR) is the ratio of a building's total floor area to the lot area. It caps how much you can build. A 5,000 SF lot with a 4.0 FAR allows about 20,000 buildable SF. Because value flows from buildable area, FAR — and any rezoning that raises it — is the central variable in site pricing.
What is assemblage and when does it make sense?
Assemblage is combining adjacent lots into a single larger development parcel, often to reach a more efficient building size or to capture zoning bonuses. It makes sense where individual lots are too small to develop efficiently and where a rezoning (as in Gowanus or Williamsburg's industrial corridors) rewards larger, denser projects.
How does a rezoning change a site's value?
A rezoning that increases allowable FAR or changes permitted use can multiply buildable area and unlock residential or mixed-use development on land that was previously industrial or under-zoned. The OneLIC rezoning enabling ~14,700 apartments across 54 blocks is the clearest recent example of value created at the neighborhood scale.
Should I sell my development site now or hold it?
It depends on where the corridor is in its rezoning and construction cycle, current land pricing, and your cost of capital. With about 43,000 units under construction citywide and 21M SF of new filings in Q1, builder demand for well-zoned sites is active — but timing against a specific corridor's pipeline is where a submarket-level read earns its keep.
