They’ve popped up all throughout town, scores of recent constructing plans by totally different firms in very totally different neighborhoods, with one factor in widespread: All of them have precisely 99 flats.
Prior to now two years, builders have filed permits for greater than 150 residential buildings with that exact variety of models, per metropolis information.
Why? As a result of at that dimension, savvy builders trying to take a serious tax break for residential developments can keep away from paying a better minimal wage to building staff — whereas minimizing the variety of inexpensive flats they need to embody.
“It feels very counter to the general objective of what we’re making an attempt to realize right here, which is that we’re making an attempt to construct extra housing,” stated Justin Pelsinger of the event agency Charney Firms, which isn’t engaged on any 99-unit tasks.
Simply 1% of proposed developments which have registered to make use of the tax break have 100 models or extra, in response to the Division of Housing Preservation and Growth (HPD). A number of proposed 99-unit buildings are clustered on the identical heaps and share a typical facade in order that they look like a single, bigger constructing.
For labor leaders, the development is a giant downside. Gary LaBarbera, president of the Constructing and Development Trades Council of Better New York, described the observe as “a rip-off,” and stated he raised the problem earlier this yr with metropolis officers in an try to shut the loophole.
“The unhappy a part of it’s, who suffers? The individuals undergo as a result of they’re constructing much less inexpensive models,” LaBarbera stated.

However builders say their method is only a affordable, if artistic, resolution to make their finances math work below the constraints of the comparatively new tax exemption program: 485-x. It got here into impact in 2024 to exchange one other tax break program that helped spur the bulk of recent residential building in New York Metropolis between 2010 and 2020.
This system is supposed to create new housing developments with a mix of market-rate and inexpensive flats — that’s, models with rents decided by the revenue degree of the tenant — utilizing solely non-public {dollars}, with out authorities funds.
That program, 485-x, requires builders of buildings with a minimum of 100 flats to pay building staff a minimal hourly wage of $40.
If a mission has lower than 100 flats, solely 20% of its models should be income-restricted, or “inexpensive,” and completely rent-stabilized. No wage minimums apply.
The proportion of inexpensive flats goes up the extra models a 485-x constructing has. For buildings with 100 to 149 flats, 25% of the full should be rent-stabilized and inexpensive for a household of 4 making about $129,600.
For buildings with a minimum of 150 flats in sure areas of town — together with Decrease Manhattan and elements of the Brooklyn and Queens waterfront — 1 / 4 of the flats should be completely rent-stabilized and inexpensive for households of 4 making about $97,200. There are additionally larger wage necessities.

Builders, architects and consultants say the necessities for minimal wages and affordability ranges, taken collectively, improve prices and restrict incomes of the event tasks. They’re discovering methods to work round them in an effort to construct much-needed housing.
“For a much bigger constructing on the fringe of 99, you’ll be able to goose the unit depend down by combining the models,” stated John Woefling, companion at Dattner Architects. “So that you’re not offering extra housing, you’re simply offering larger models.”
Elie Pariente, principal at EMP Capital Group, stated his firm plans to assemble a number of tasks with 99 flats every, some with a number of 99-unit buildings on the identical lot, although he didn’t specify the place. He stated if his developments had been any bigger, and thus topic to the 485-x necessities, he wouldn’t be capable of lean on his longstanding relationships with sure contractors.
“A whole lot of the trades that we usually use wouldn’t work,” he stated. “If we had been to go for greater than 99 models, we must rent brand-new trades and brand-new contractors that we’ve by no means labored with earlier than.”
Of the 299 proposed developments which have registered to make use of the tax break, about 10% of them comprise precisely 99 flats, in response to information from HPD.
Between April 2024 and 2026, builders have filed permits for greater than 120 further buildings with precisely 99 flats, however these don’t seem in HPD’s registration information, in response to a evaluate by THE CITY.
It is a notable leap from the 13 buildings with 99 flats that builders proposed between 2008 by way of 2023, a earlier evaluation by the Actual Property Board of New York discovered.
Mayor Zohran Mamdani campaigned on constructing 200,000 inexpensive flats over a decade, utilizing union labor. The early outcomes of the 485-x program — which was licensed by the state in 2024 — could elevate questions on how possible that objective is, however Metropolis Corridor spokesperson Matt Rauschenbach stated officers are monitoring this system’s implementation.
“We are going to proceed to work with our companions in Albany, labor, tenants and the Metropolis Council to construct a extra inexpensive metropolis — together with by each constructing new housing and guaranteeing that the individuals constructing it have good, secure, high quality jobs,” he stated in an announcement.
Extra Buildings, Extra Prices
A number of the developments Pariente is engaged on are single buildings with 99 flats, equivalent to one which will probably be positioned on the border of Crown Heights and Prospect Heights in Brooklyn. Others, he stated, can have a number of 99-unit buildings on the identical lot.
“Completely different heaps lend themselves to the 99-unit idea greater than others,” he stated. “The bigger the lot, the extra flexibility you’ve subdividing it.”
Such developments — say, three 99-unit buildings performing as one — have duplicative components, which may add each up-front prices and be costlier to keep up than a comparable particular person constructing with 297 flats in it.
“We’re now placing in added partitions, added trash rooms, added stairs, added elevators, so we’re mainly dropping sq. footage that will have been out there for models, and placing it into these new structural components which are among the costliest and highest-carbon components in a constructing,” stated Toby Snyder, senior affiliate at FXCollaborative Architects, referring to energy-intensive supplies and processes.
Examples abound: On the Higher East Aspect, a constructing below building seems as one tower, however is technically two, every with 99 flats. In Highbridge, not removed from Yankee Stadium, a developer deliberate twin buildings nestled collectively on one leafy road nook, with 99 flats every.

In Boreum Hill, a developer filed permits for 3 buildings with 99 flats every. In architectural drawings, the buildings seem seamlessly related. One lot in Downtown Brooklyn will see 5 buildings with 99 models every.
However breaking up a growth into separate 99-unit segments on one lot meets its restrict on small heaps in dense areas. As an example, in Midtown and Lengthy Island Metropolis — all neighborhoods not too long ago rezoned for extra housing — rather a lot that would accommodate a tower with a number of hundred flats would seemingly be too small to separate the constructing aside into a number of 99-unit buildings.
“If we’re not constructing these bigger tasks the place the zoning and density enable for it, then we’re leaving models on the desk, and we’re not likely fixing for our affordability or housing disaster,” stated Basha Gerhards, government vp of public coverage at REBNY.
Labor leaders are important of the 99-unit playbook.
“In fact the developer goes to say, ‘Oh, the numbers don’t work,’ as a result of they’re making an attempt to justify the scheme that they’re engaged in,” LaBarbera stated. “They don’t need to pay truthful wages. They need to revenue, revenue, revenue.”

Kevin Elkins, political director of the carpenters’ union, stated builders danger dropping their tax breaks as they transfer ahead with a number of, clustered buildings every containing 99 flats.
“A whole lot of these buildings are sharing the identical mortgage. They’re sharing the identical facilities. They’re sharing the identical tax heaps. It’s so clear what’s happening,” Elkins stated. “We will probably be offering, if obligatory, proof that that is one constructing, that staff weren’t paid the wages they had been speculated to be paid.”
New York Metropolis Comptroller Mark Levine would in the end be the enforcer of the prevailing wage portion of the tax exemption, although his workplace hasn’t acquired any associated complaints.
Exception to the Rule
There’s one exception to the 99-apartment development, based mostly on metropolis information. Developer TF Cornerstone will depend on the 485-x tax program and nonetheless go massive, with 1,060 flats deliberate throughout three buildings on the Greenpoint waterfront, and 278 flats deliberate in Chelsea.
Jon McMillan, TF Cornerstone’s senior vp and director of planning, stated these developments are doable as a result of the corporate has lengthy been a union contractor, and through the use of its personal cash, it doesn’t should depend on others for financing. However the course of hasn’t been simple.
“That is very, very difficult for us. We need to transfer ahead with these two tasks however they don’t work for us practically in addition to tasks we’ve completed up to now, or as we’d like for tasks to work,” McMillan stated. “We’re doing these buildings at a decrease fee of return than we usually do and than is sustainable, however we need to preserve our group busy.”
Nonetheless, there’s an opportunity extra builders may use 485-x to assemble bigger condo buildings sooner or later, like these ending tasks below a earlier tax exemption program. And a few are ready on higher-level modifications earlier than transferring ahead, together with the reducing of rates of interest, prices of products and supplies and tariffs.
“If we had been in a decrease rate of interest setting and commodity pricing got here down, and insurance coverage pricing was not at file excessive, may we make one thing work with the $40 wage ground?” stated Eli Weiss, principal at Pleasure Development Corp, whose tasks sometimes comprise 150 to 175 flats. “Completely.”
