New York's 2019 Rent Law and the Rules It Rewrote for Stabilized Apartments

In mid-June 2019 the New York legislature did something it had not done in a generation: it passed a rent law that tenant organizers had largely written. For decades the state's rent rules had come up for renewal every few years, and every few years the renewal had arrived with new loopholes for landlords tucked inside, negotiated in the Capitol by a Senate that the real estate industry knew how to work. This time the Senate was different. Democrats had taken real control of it in the 2018 elections, after primary voters ousted most of the breakaway Democrats who had governed alongside Republicans. Governor Andrew Cuomo signed the Housing Stability and Tenant Protection Act almost as soon as it reached his desk. Owners of older buildings described it as the end of their business model. Tenants described it as the end of a slow leak that had drained hundreds of thousands of apartments out of regulation.

In short: The 2019 law ended the rules that let New York landlords move stabilized apartments to market rent, curbed rent increases tied to renovations, and made the system permanent. Owners sued and lost; the fight shifted to the yearly Rent Guidelines Board vote and to buildings whose finances the law squeezed.

A system built in pieces

To understand what changed, it helps to know how odd New York's rent system already was. Rent stabilization dates to 1969 and was expanded by the Emergency Tenant Protection Act of 1974. It covers most apartments in buildings of six or more units built before 1974, along with newer buildings that accepted tax breaks in exchange for regulating rents. It is not a freeze. A city body, the Rent Guidelines Board, votes each year on how much stabilized rents can rise on one- and two-year leases. Tenants have the right to renew. Owners can pass along certain costs.

It is also a system that was designed to shrink. Starting in the 1990s, Albany layered on rules that let apartments leave regulation for good. The biggest was high-rent vacancy deregulation: once the legal rent on a vacant unit crossed a threshold, which by 2019 stood at a little under $2,800 a month, the owner could take it out of the system permanently. On its own, that threshold would have taken decades to matter. Combined with the other rules, it became a conveyor belt.

The rules that moved apartments to market

The conveyor belt had three main gears, and the 2019 law removed or weakened each one.

The vacancy bonus. Each time a stabilized apartment changed tenants, the owner could raise the legal rent by up to 20 percent on top of the board's yearly increase. Turnover, in other words, was profitable in itself.

Individual apartment improvements. When an owner renovated a vacant unit, a fraction of the cost could be added to the rent permanently. New cabinets, new floors and new appliances could push a unit's legal rent over the deregulation threshold within a turnover or two. Tenant advocates long argued that the claimed costs were hard to verify and sometimes inflated; owners argued that the work was real and the old units needed it.

Major capital improvements. Building-wide work such as boilers, roofs and windows could likewise be added to every tenant's rent, permanently.

Together these gave owners a strong reason to want tenants out, and tenant groups documented harassment cases in gentrifying neighborhoods that seemed to follow exactly that logic. The state's own housing agency estimated that many tens of thousands of units had left stabilization through deregulation since the 1990s; advocates put the total higher.

What the 2019 law did

The Housing Stability and Tenant Protection Act changed the incentives in a few strokes.

1. It repealed high-rent vacancy deregulation and the related high-income deregulation, so stabilized apartments can no longer leave the system because their rent or their tenant's income crossed a line.
2. It eliminated the vacancy bonus and the longevity bonus that had allowed extra increases when a long-term tenant left.
3. It sharply limited individual apartment improvement increases, capping the total cost an owner can recover over a 15-year period at $15,000 and making those increases temporary rather than permanent.
4. It cut the amount of building-wide improvement costs that can be passed through each year and made those increases expire after 30 years.
5. It locked in "preferential rents," so a tenant paying less than the legal maximum cannot be hit with a jump to the maximum at renewal.
6. It made the rent laws permanent, ending the cycle of expiration and renewal that had given the industry leverage every few years.
7. It allowed municipalities anywhere in the state that meet a housing-emergency test to opt into stabilization, and it added statewide protections for renters in unregulated housing, including limits on security deposits and stronger rules on eviction procedure.

The phrase that best describes the result is that stabilization stopped being a waiting room. Before 2019, a stabilized apartment was a unit whose regulated life had an expected end. After 2019, it was a unit that stays regulated.

How a coalition outside the Capitol got its bill

Laws like this do not usually pass because a governor wakes up convinced. The 2019 act was the product of a coalition that called itself the Upstate Downstate Housing Alliance, which brought together tenant unions in New York City with tenant groups in Rochester, Buffalo, Albany, the Hudson Valley and elsewhere. That geography was the strategy. For decades, rent regulation had been treated in Albany as a New York City issue, which let upstate legislators of both parties treat it as someone else's fight and let the real estate industry frame every vote as the city taking something from everyone else.

The alliance changed the frame by organizing renters outside the city, many of whom had no rent protections at all and were seeing sharp increases of their own. Its platform was called "universal rent control," and while the final law fell short of that, the opt-in provision for localities beyond the city and the new statewide rules on security deposits and eviction procedure came directly from the upstate side of the coalition. Tenants rode buses to Albany, packed hearings, and sat in legislative offices. They also did something less glamorous: they knocked on doors in the 2018 primaries for challengers running against the breakaway Democrats, which is how the Senate majority that passed the bill came to exist.

There is a lesson in that sequence. The bill was not won in June 2019. It was won in September 2018, in low-turnout primaries most voters ignored, and in years of organizing before that. When people ask how a policy that the industry had blocked for a generation suddenly passed, the answer is that the people who wanted it changed who was sitting in the room.

What owners lost, stated fairly

It would be easy to write the owners' side as greed. It would also be wrong, or at least incomplete.

Many stabilized buildings are old. Their boilers, pipes, elevators and facades need constant, expensive work. Before 2019, an owner could renovate a unit when a long-term tenant left and recover the cost over time through a higher rent; the vacancy bonus and deregulation offered an eventual upside. Banks valued buildings partly on that upside. When the law removed it, the value of many rent-stabilized buildings fell, in some cases sharply, and lenders who had made loans based on the old projections found themselves holding debt on properties now worth less.

Small and mid-size owners also said the cap on apartment improvements made it uneconomic to renovate units that needed full gut work. Reports surfaced in the years after the law of stabilized apartments sitting vacant because their owners said renovation would cost far more than the law allowed them to recover. Tenant groups dispute how many units are truly held off the market for that reason and argue that some owners are waiting for the law to change. Both things can be true in different buildings.

The honest progressive position recognizes the problem. A system that only tells owners what they cannot charge, without a plan for how 50- and 100-year-old buildings get repaired, invites decay. The remedy is not to restore the conveyor belt that pushed tenants out; it is public money for capital repairs tied to keeping rents affordable, faster inspections, and a path for distressed buildings to move to nonprofit or mission-driven owners before they fall apart.

The courts said yes, the industry kept fighting

Owners and their trade groups sued almost at once, arguing that the law amounted to an unconstitutional taking of their property. The federal courts in New York rejected the challenges, relying on decades of precedent holding that rent regulation is an ordinary use of a state's power over the landlord-tenant relationship. In early 2024 the Supreme Court declined to hear the leading cases, leaving those rulings in place. One justice wrote that the Court might consider the question in a future case with a better record, which is why the industry has kept bringing them.

So the fight moved. Every year, the Rent Guidelines Board vote is now the most watched number in New York housing, because with the deregulation rules gone, the board's increase is the main lever on stabilized rents. The board's members are appointed by the mayor, which turned the 2025 mayoral race into a referendum of sorts. Zohran Mamdani won that race in November 2025 after campaigning on a promise to freeze stabilized rents. Whether and how often that promise is kept is a question for the board's votes, and readers should look at the vote itself rather than any campaign description of it.

Good cause and the next fight

The 2019 law covered roughly a million stabilized apartments but left out the larger number of market-rate units, whose tenants could still face any increase at renewal or be told to leave at lease end. In 2024 the legislature passed a Good Cause Eviction law as part of the state budget. It applies in New York City and in other localities that choose to opt in, requires a reason to refuse renewal for most market-rate tenants, and treats increases above a set formula, roughly 5 percent plus inflation with a 10 percent maximum, as presumptively unreasonable unless an owner can justify them. It contains exemptions for small landlords and newer buildings, and it was the product of a long negotiation in which tenant groups gave up some of what they wanted.

Notice the shape of that compromise. It looks a lot like the anti-gouging approach used by Oregon and California rather than the stabilization approach New York pioneered. New York now runs both systems side by side.

That dual structure raises a question for tenants that is easy to miss: which system am I in? A renter in a pre-1974 building with six or more units is probably stabilized, but not certainly, because some units left the system before 2019 and stayed out. A renter in a newer building may be stabilized because the developer took a tax break, and many such tenants do not know it. The state housing agency will provide a unit's registered rent history on request, and tenant groups routinely help renters read those records, which sometimes reveal that an apartment was deregulated improperly and that the tenant is owed money.

The reframe: a law about who wins when a tenant leaves

Most coverage of the 2019 law asked whether it was fair to landlords. A better question is what any rent system rewards. Before 2019, New York's rules rewarded turnover. Every departure meant a bonus, a renovation recovery, and a step closer to deregulation. A system that rewards turnover will produce turnover, and in a city with too little housing, turnover means displacement.

The 2019 law changed the reward. Owners now do best by keeping buildings full and well run. That is a better incentive for a city that needs stable neighborhoods and schools. It also means the city and state have taken on responsibility for the costs that turnover used to cover. A law that removes one way of paying for old buildings has to be followed by another. Progressives who won the 2019 fight should be the loudest voices for that second step, because if the buildings decline, the law will get the blame.

What you can do

New York's rules are set in Albany and at the Rent Guidelines Board, but the pattern applies in any state with rent rules, or a ban on them.

• Call the people who wrote the law. Rent stabilization is state law. Look up your state senator and assembly member, and ask where they stand on funding repairs in stabilized buildings and on enforcement against owners who keep units empty.
• Show up for the board vote. The Rent Guidelines Board holds public hearings before its annual vote. Testimony from tenants who can describe what an increase means for a household budget is part of the record the members see.
• Find a tenant association or legal clinic. Many New York neighborhoods have tenant groups that help renters check whether their apartment is stabilized and whether their rent history is accurate. Search the housing and legal aid groups near you.
• Follow the cases. Challenges to rent laws keep reaching the federal courts. The court-watch page tracks the Supreme Court's opinions and emergency docket, and the courts topic page follows the cases on their way up.
