The law covering nearly 1 million New York City rent-stabilized tenants expires on June 15 — and the Democrat-run state Legislature is vowing to make sweeping changes that would limit landlords’ ability to hike rents or remove apartments from government control.

And Gov. Andrew Cuomo and Mayor Bill de Blasio are on board with many of the pro-tenant measures under consideration.

There are about 907,000 apartments in the city covered by the rent-stabilization law, and landlords are not going down without a fight. One proposal landlords are opposing would strip their legal authority to raise rents to recoup costs when they renovate their buildings or individual apartments.

They said eliminating their ability to raise rents under the Major Capital Improvement program will discourage them from keeping their properties in good repair.

“I now have to put in a new elevator in one of the buildings. That would be a $150,000 to $200,000 job without the MCIs. I don’t know how I would do it, I just wouldn’t be able to do it,” said Chris Athineos, 50, whose family-owned business owns nine buildings housing about 150 tenants, with half rent-stabilized.

“It’s very frustrating because I want to provide a better service, a better building for my tenants, and it’s very frustrating if we wouldn’t be able to do that.”

Cuomo and de Blasio have found common ground on limiting rent hikes for capital improvements but not entirely scrapping the program. “You want people to do capital improvements, but you don’t want to do reimbursement more than the capital improvement,” Cuomo said.

Another measure would end vacancy decontrol, which allows landlords to remove an apartment from the state’s rent-regulation rolls when the unit is empty and the rent hits $2,733.

Tenant advocates complain that under vacancy decontrol since 1994, at least 155,000 rent-stabilized apartments were removed from the rent rolls and went into the private market.

Another bill would solidify “preferential rent,” which is a discounted rent tenants pay that is below the legal registered rent. About 266,000 families in the city pay preferential rents.

Another measure would wipe out a 20% bonus or increase landlords can collect any time a rent-stabilized apartment turns over. Senate Majority Leader Andrea Stewart-Cousins (D-Yonkers) and Assembly Speaker Carl Heastie (D-Bronx) issued a joint statement that said, “The Senate and the Assembly together are ready to work with the governor to deliver the strongest rent package ever to meet the needs of tenants across the state of New York.”
