NYC Housing Policy · 467-m vs 485-x
Two housing incentives. Two very different early market responses.
New York enacted 467-m and 485-x as part of the same 2024 state housing package. Both programs pair substantial property-tax benefits with permanent affordable-housing requirements. But the market's early response to them looks strikingly different.
The visible office-conversion pipeline consists of relatively few but exceptionally large projects, concentrated in Manhattan's highest-cost commercial districts. The first wave of 485-x registrations is much larger by project count but consists primarily of smaller developments in Brooklyn, Queens and the Bronx.
This is not yet a comparison of completed apartments. It is an early look at how developers are responding to two different statutory and economic frameworks—and what that response may tell us about how to design housing policy that actually produces homes.
The early numbers
- 20,876 potential apartments · average 298 per project
- Approximately 5,219 permanently affordable apartments at the statutory 25% minimum
- 84% located within Manhattan's prime commercial core
- 55 filed or underway · 15 in active plan review
- 11,869 intended apartments · average 39.4 per project
- 2,557 intended restricted apartments
- 96% located in Brooklyn, Queens and the Bronx
- 30 registrations at exactly 99 units · only 3 above 100 units
Where each program is producing activity
The geography is nearly a mirror image.
Marker area ∝ units. Hover any building for detail. 467-m conversions cluster inside the MPD line (Manhattan's least-affordable core); 485-x registrations sit almost entirely in the outer boroughs.
The 467-m-eligible conversion pipeline is concentrated in Midtown and Lower Manhattan, where housing is expensive, developable land is scarce and affordable apartments are especially difficult to produce. The first wave of 485-x registrations is concentrated outside Manhattan and largely reflects smaller-scale ground-up construction.
That makes 467-m notable not only for the number of apartments it may produce, but for where it is producing them. A single 1,200-unit conversion complying at the statutory minimum can create approximately 300 permanently affordable apartments in a high-cost neighborhood—comparable to the affordable component of many smaller projects combined.
What the market response may be telling us
The comparison does not suggest that developers oppose permanent affordability. Both programs require it.
Instead, it suggests that housing production depends on whether the complete economic package works: the tax benefit, affordability requirement, labor costs, land or acquisition basis, construction costs, financing conditions and permissible density.
The concentration of 485-x registrations at exactly 99 units is particularly revealing. One hundred units is the point at which additional construction-wage requirements begin to apply. The clustering immediately below that line does not prove that the wage threshold determined every project's design, but it is strong evidence that the statute is influencing project size and phasing.
467-m appears to be generating a different response. Because conversions can begin with a distressed or obsolete office asset, reuse much of an existing structure and operate under a different labor framework, the program is supporting projects with hundreds—and sometimes more than one thousand—apartments.
The public-policy implication
Good housing policy should be measured not simply by the generosity of its benefits or the ambition of its requirements, but by whether the complete framework produces financeable projects at meaningful scale.
The early evidence suggests that 467-m has found an unusually productive balance. It is helping turn obsolete commercial buildings into large mixed-income residential communities, including permanently affordable apartments in some of the city's most expensive neighborhoods.
485-x remains an important and still-evolving program. Its registrations may ultimately mature into a substantial housing pipeline. But the early project-size and geographic patterns deserve close attention. If a major citywide housing incentive consistently produces projects immediately below a statutory threshold, policymakers should ask whether the program is encouraging the amount, scale and location of housing New York intended.
How to read the data
These figures are pipeline indicators, not completed-unit counts.
The 485-x figures are registrations by prospective applicants. They reflect intended projects and unit counts, not approved tax benefits, construction starts or completed apartments.
The conversion figures combine office-to-residential projects that are filed, underway or in active plan review. Projects have been identified through Department of Buildings records, public reporting and comparison with the New York City Comptroller's conversion inventory. Potential eligibility for 467-m should not be interpreted as confirmation that every project has applied for or received the benefit.
Apartment counts for projects without publicly filed unit totals use an estimated yield of approximately 860 gross square feet per apartment. Estimated affordable-unit counts generally apply the statutory 25% minimum; actual project elections and final unit totals may vary.

The larger conversion story
Office conversions are emerging as a meaningful part of New York City's housing pipeline—not simply as a response to post-pandemic office distress, but as a durable model for adaptive reuse.
They can remove obsolete space from the office market, restore activity to commercial districts, reuse existing buildings and infrastructure, and create thousands of new homes in neighborhoods where conventional ground-up development is difficult.
