The New York City Council is expected to take legal action against Mayor Eric Adams after his administration refused to implement a controversial housing voucher program.

The council on Thursday passed a resolution that’ll grant Speaker Adrienne Adams the power to sue City Hall for failing to enact three laws reforming rental assistance supplements, known as CityFHEPS.

The speaker told reporters before the vote that the council hadn’t yet decided whether it would sue the mayor or join another lawsuit challenging his administration’s inaction on the laws. 

“We are going to wait and see what happens once we authorize and pass the resolution today,” Speaker Adams said — adding that there have been no negotiations with City Hall over the implementation of the laws, which were due to go into effect Wednesday.

The threat of legal action is the latest salvo in escalating tensions between Mayor Adams and the council after the legislative body dealt him a blow last month by rejecting his vetoes of a contentious police-stops bill and one that banned solitary confinement in city jails.

The stalled housing package allows New Yorkers to apply for vouchers without entering the shelter system if facing eviction and ends a rule requiring people to stay in shelters for 90 days before becoming eligible for a voucher.

It also bars landlords from deducting costs of utility bills from a voucher and would increase the income level of cutoff to qualify for aid.

The mayor vetoed the slate of legislation last year arguing the plan would be too costly to the city, putting the price tag at $17 billion over five years, $7 billion more than the council has estimated.

The council fiercely disputed the mayor’s math on the cost and overrode the mayor’s veto 42-8 in July, the first of three overrides in the Adams administration.

In December, just weeks before the law was set to go into effect, City Hall told the council it had no plans to implement the law, citing the city’s current financial burdens while dealing with the $10 billion migrant crisis.

The speaker had given City Hall a Feb. 7 deadline to implement the laws.

“The city has a responsibility to comply with local laws and the council must maintain its legal options to ensure compliance,” council spokesperson Rendy Desamours said.

Hours earlier, Mayor Adams announced a program to fast-track 1,000 units of affordable housing by partnering with nonprofits to leave or buy buildings to turn in low-cost apartments. 

“We always seek to work collaboratively with our colleagues at the City Council, and look forward to identifying more areas of common ground to support New Yorkers experiencing homelessness, including an aggressive, citywide effort to build more housing in every neighborhood,” said City Hall spokesperson Kayla Mamelak.
