Week in Insights: NYC Must Stop Suppressing Housing Density

Sept. 14, 2025, 2:02 PM UTC

There’s a hot new number in New York City. Over the past year, developers have filed more permits for 99-unit buildings than in the previous 16 years combined.

The cause is 485-x, a tax incentive meant to encourage affordable housing development and raise construction wages. It somewhat fumbles at both.

Here’s how it works. Real estate developers get a tax break if they include a certain number of affordable housing units in new buildings. A key policy element is a unit threshold, 100, beyond which developers must pay their crews at least $40 an hour—with increases at 150 units and above.

Developers have responded by building 99-unit buildings over and over again.

This situation has a historical parallel. In 1696, England imposed a property tax based on the number of windows in a home, assuming that windows were a decent stand-in for home size and owner affluence. The result was predictable: Homeowners bricked up windows, and architecture got dimmer across the country for the next century and a half.

New York is now doing the same thing, but instead of creating a distortion against daylight, it’s suppressing housing density. Lawmakers can’t claim to solve a housing crisis while placing artificial cliffs in an incentive structure. And they certainly can’t expect developers to act against their own financial interests.

To address the city’s housing crisis, New York policymakers must stop micromanaging unit counts and start designing incentives that scale. Otherwise, what started as an attempt to ease the housing crunch will become another fun fact of history.

Technically Speaking design by Jonathan Hurtarte/Bloomberg Tax

Rhode Island’s “Taylor Swift Tax” on non-primary residences worth more than $1 million may seem reasonable on the surface, but “narrowly tailored taxes pegged to valuation thresholds are a nightmare dressed like a daydream,” Andrew Leahey writes in his latest Technically Speaking column.

States that implement similar policies should consider multistate compacts and regular property assessment cycles, but targeting the income or even wealth of high-income residents would be a better tax policy direction, Andrew argues. Read More
