Zoning and land use
Air rights and transferable development rights
Air rights move three ways in New York City: a zoning lot merger, a landmark transfer, or a special district mechanism. Each is a recorded real estate deal.
How do air rights actually get transferred in New York City?
Quick Answer
How much may be built
Who does this land on?
Developers assembling sites, owners of low-rise buildings sitting under unused capacity, and buyers of any lot whose value assumes rights that may already be gone.
What governs it?
- The zoning lot definition in the Zoning Resolution, which is what a merger actually creates
- The Zoning Resolution provisions permitting transfers of development rights from landmark sites, which require a special permit
- Special purpose district provisions that create their own transfer mechanisms in defined areas
- The recording statutes, because the declaration and the zoning lot development agreement are recorded instruments
- The New York City real property transfer tax, which reaches a conveyance of development rights
How does the process run?
- Confirm the rights exist: calculate the permitted floor area for the whole zoning lot and subtract what is built
- Confirm nobody has already taken them, by searching ACRIS for prior declarations, zoning lot development agreements and waivers
- Identify every party in interest whose consent or waiver is required, including fee owners, mortgagees and certain lessees
- Negotiate the transfer documents: the declaration of zoning lot restrictions, the zoning lot development agreement, and any light and air easement
- Obtain subordinations and waivers from the mortgagees, which is usually the long pole in the schedule
- Record the instruments, pay the applicable transfer taxes, and file the zoning lot certification with the Department of Buildings
- For a landmark transfer, run the special permit application before any of the above is worth signing
Where does it bite in a transaction?
- A site is assembled on the assumption of available rights that a recorded declaration already moved
- A mortgagee refuses to subordinate and the transfer cannot be recorded in a form the Department will accept
- A transfer is priced without accounting for the transfer taxes a conveyance of development rights attracts
- A landmark transfer is budgeted as a closing rather than as a special permit application with a public review calendar
Are air rights real property?
They are treated as an interest in real property when they are conveyed, which is why the transaction is documented, recorded and taxed like one. That is also why the diligence looks like title diligence: a search of the record, consents from everyone with a recorded interest, and a title company reading the same chain the buyer is.
What is a party in interest and why does it matter?
The Zoning Resolution requires the consent or waiver of everyone holding a recorded interest in the lots being joined, including mortgagees and certain lessees. Missing one is not a technicality: the Department of Buildings will not certify the zoning lot, so the floor area does not move even though money changed hands.
Can a landmark sell its unused floor area to anyone?
No. Transfers from a landmark site run through a specific Zoning Resolution provision that limits where the rights may land, usually to an adjacent lot or one across the street, and requires a special permit with findings. It is a public review process, not a private conveyance.
Do transferred rights show up in a title search?
The instruments do, because the declaration and the agreement are recorded against the affected lots. That is exactly why the search is run before the offer: a lot marketed with unused capacity may carry a recorded declaration that assigned the capacity to a neighbor years earlier.
