A proposed tax on luxury properties in New York City is raising concerns across the construction and real estate sectors after executives at Citadel suggested it could jeopardize a multibillion-dollar development project in Midtown Manhattan.

The tension follows remarks and policy proposals from New York City Mayor Zohran Mamdani, who announced a new “pied-à-terre” tax targeting high-value residential properties owned by non-primary residents. The plan would apply to homes valued above $5 million and is expected to generate significant revenue for city services.
In a Tax Day video, Mamdani emphasized his campaign promise, stating, “When I ran for mayor, I said I was going to tax the rich. Well, today we’re taxing the rich.”
The announcement has drawn pushback from business leaders, including those tied to major construction investments in the city.
Executives at Citadel, led by billionaire Ken Griffin, indicated the firm may reconsider moving forward with a major redevelopment project at 350 Park Avenue.
“We are about to commence the redevelopment of 350 Park Avenue, creating 6,000 highly paid construction jobs and supporting the creation of more than 15,000 permanent jobs in mid-town New York,” wrote Citadel COO Gerald Beeson in a letter. “The project—if we move forward—will entail more than $6 billion dollars of spending.”
The statement signals potential uncertainty for one of the city’s largest planned construction efforts, which would have significant implications for contractors, labor markets and the broader development pipeline.
Beeson also criticized the mayor’s rhetoric, writing, “It is shameful that he used Ken’s name as the example of those who supposedly aren’t carrying their fair share of the burdens associated with New York City’s often costly and wasteful spending.”
He added, “In doing so, the mayor has once again manifested the ignorance and disdain of the elite political class towards those who have been consistently committed to building one of the greatest cities in the world.”
The proposed tax, backed by New York Gov. Kathy Hochul, still requires approval from the state legislature. If enacted, it would apply to one- to three-family homes, condominiums and co-ops owned by individuals whose primary residence is outside New York City.
City officials estimate the measure could generate at least $500 million annually, funding initiatives such as child care, sanitation and neighborhood safety.
Mamdani defended the policy as a way to address inequities in the housing market, stating it would fix “a fundamentally unfair system.” He added, “These units are sitting empty. And even so, they’re able to reap the huge financial rewards of owning property in, dare I say, the greatest city in the world.”
However, industry voices argue that high-end residential investment plays a critical role in sustaining construction activity and job creation. Billionaire investor Bill Ackman echoed that sentiment in a public post, writing, “Non-residents who spend millions of dollars on NYC apartments help drive NYC’s economy. The Ken Griffins of the world make NYC high end development viable, driving high-paying construction, brokerage, legal, marketing, and other jobs in NYC.”
The debate underscores a broader tension between public policy goals and private investment incentives, particularly as major urban construction projects depend heavily on capital from high-net-worth individuals and institutional investors.
For contractors and developers, the outcome of the policy discussion could shape the near-term outlook for large-scale projects in one of the nation’s most active construction markets.
