Can Mayor Mamdani Freeze the Rent? It’s Complicated.

 

I published a column with Nestor Davidson in Vital City, Can Mayor Mamdani Freeze the Rent? It’s Complicated. It reads,

Zohran Mamdani, the newly elected mayor who promised as a candidate to freeze the rent for rent-stabilized units each year in his four-year term, will soon seek to make good on his promise.

He can’t do it alone. He needs the cooperation of the NYC Rent Guidelines Board, an appointed body on which both of us have served as chair in recent years. The RGB was created pursuant to state law to set rent adjustments for apartments in the city that are subject to the Rent Stabilization Law. About one million of New York City’s over three-and-a-half million units of housing are rent-stabilized.

The incoming Board — on which Mamdani has made a majority of appointments — will begin its work this month. At the top of its agenda will almost surely be considering whether to keep the rents of rent-stabilized housing at current levels. As it does its work, the Board can best serve the city if all members are committed to carefully reviewing data collected and analyzed by RGB staff and other information brought to the board by experts and the public before reaching its decision.

Put differently, the RGB should not simply execute the mayor’s command. There are laws to follow and economic data to consider. The stakes are high for tenants facing increased housing burdens, for landlords facing increasing costs and for the fabric of our diverse city.

The Rent Guidelines Board’s mandate

The City’s rent stabilization system differs from rent regulation in other jurisdictions. While some jurisdictions allow landlords to increase rent when an apartment turns over to a new tenant, the Housing Stability & Tenant Protection Act of 2019 (HSTPA) eliminated vacancy rent hikes. Rent adjustments in New York are also set by a Board instead of being based on a formula that is tied to the inflation rate. The Board can therefore set rent increase rates higher or lower than inflation, based on the statutory criteria it applies.

The media rarely explains the RGB’s decision-making process clearly and sometimes echoes misunderstandings about how the Board works. Perhaps the biggest misunderstanding is that mayors decide whether and how much rents go up. But that is not how rent stabilization was designed to work. Even though one of us chaired the Board during the mayoralty of Bill de Blasio, who used the bully pulpit to advocate for a rent freeze, we know well it is the members of the Board who have the sole power to make this decision. Each of us had to work to get a majority of the Board to support what became the adopted guidelines each year. Board members take their roles seriously and typically engage in lengthy discussions about the data before deciding which proposals to support. Rather than seeing a rent freeze as a simple test of mayoral power, the public is best served by understanding the limited but important function of the Board and the constraints on its decisions.

Let’s step back a bit. The Rent Stabilization Law (RSL) charges the Board with one central task: adjusting rents of rent-stabilized units after reviewing “the economic condition of the residential real estate industry,” cost of living data and a catch-all, “such other data as may be made available to it.” Thus, there is no single, simple formula for the Board to apply.

To get into the weeds, the law requires that the Board review data regarding the operating and financing costs landlords are bearing, including (1) real estate taxes and sewer and water rates; (2) gross operating maintenance costs (such as insurance premiums, governmental fees and the cost of fuel and labor, among other things) and (3) costs and availability of mortgage financing. The Board is also charged with considering the supply of housing as well as vacancy rates. While tenants’ rent burden — the portion of their income they spend on rent — is not explicitly mentioned in the RSL, the Board has interpreted its mandate for decades to include an assessment of housing affordability.

While the mayor appoints all members of the Rent Guidelines Board (or a predecessor mayor, for holdovers), it is an independent body that is required by law to make its own determination about rent adjustments. The Board is composed of the chair, who serves at the pleasure of the mayor; two members who represent tenant interests; two members who represent landlord interests and four members who represent the general public. Other than the chair, members serve terms of two, three or four years.

Tenant members typically focus on affordability for today’s tenants. Landlord members often focus on the finances of rent-stabilized buildings, such as whether they are earning enough to cover maintenance and capital repairs as well as a profit for their owners. Those are appropriate agendas for those two sets of members. Chairs consider all of this, but also usually focus on the long-term, asking whether proposed rent adjustments will ensure that the rent-stabilized housing stock has sufficient revenue to be maintained for its residents for years to come.

Landlords have repeatedly challenged the Board’s annual rent guidelines, but courts have generally deferred to the Board’s expertise and upheld its balancing of the competing concerns of increasing costs for landlords and diminishing affordability for tenants.

The state of the housing stock

The Housing Stability and Tenant Protection Act, passed by the state Legislature and signed into law by then-Gov. Andrew Cuomo in 2019, dramatically altered the finances of the rent-stabilized housing stock. Proponents of the law wanted to limit ways that landlords could raise rents and, in particular, curb incentives to exit the program through high-rent/high-income deregulation. They succeeded in doing that, but rents flattened and buildings dropped in value as a result. Many buildings in the program are now showing financial distress as expenses have continued to increase each year.

A recent Furman Center report shows that there is reason to worry that the current regulatory environment has set up a dynamic where around two-thirds of the rent-regulated housing stock is on a trajectory of financial distress — potentially including mortgage default and bankruptcy — that will result in deteriorating quality in housing for tenants. This would mean more heat and hot water outages, more pest infestations and more lead paint hazards, among other health and safety concerns.

That picture of the current stock brings us back to how the Board makes its decisions. As we noted, many people think that the mayor simply tells the Board how to vote. That has not been our experience. Nor has it been our sense of the experience of other chairs we have spoken with.

It is true that mayors often appoint members who are broadly sympathetic to either tenants or owners. Now, even with some members whose terms straddle previous administrations, Mayor Mamdani has tapped a majority of the incoming Board.

The mayor does not — and should not — “control” them. With a process designed to provide broad technical and public input, chairs and other Board members formulate proposed rent guidelines that reflect the data that the RGB’s research staff provides them. The Board staff and members take their work seriously. They must consider the data before them, and the Rent Stabilization Law requires the Board to make challenging calls to balance increasing costs for building owners with affordability concerns for tenants. If the record does not support a finding that the Board’s decision was based upon their statutory mandate, it is open to challenge.

Some have asked why a rent increase or freeze needs to be boiled down to a single number when so many buildings and building owners face different pressures and conditions. It’s a fair question, but right now, the law doesn’t allow for fine-grained distinctions. Each year’s rent guidelines are a blunt instrument that applies to every building with rent-stabilized units. This means that the same figure applies to a building in the Bronx composed entirely of 99 rent-stabilized units and to the one remaining rent-stabilized unit in a 99-unit luxury building in midtown Manhattan where the owner has no limitation on how much it can charge for those ”market rate” units.

The Mamdani administration will need to grapple with this blunt instrument, just as every previous administration has had to. Ultimately, the Board must pay close attention to the data to determine how rents should be adjusted — understanding that a freeze will likely harm buildings in deep financial distress even as it would aim to help tenants in buildings whose landlords are doing just fine.

The Board does not act alone

Whatever the Board decides, many stabilized buildings will continue to face financial distress. But the fate of the rent-stabilized housing stock does not solely rest with the Board. The governor, the Legislature, the mayor and the City Council can all act to ensure that the rent-stabilized housing stock has sufficient funding for maintenance and needed capital repairs. While the City and State have many tools at their disposal to address financial gaps, the three main avenues for helping distressed buildings are bigger rent increases, new subsidies or reduced costs for buildings in financial distress.

After the passage of the 2019 HSTPA, rent increases for rent-stabilized units can only be authorized by the Board (or, subject to stricter limits under the HSTPA and subsequent amendments, through temporary Major Capital Improvement (MCI) increases and permanent Individual Apartment Improvement (IAI) increases). And because previous amendments to the RSL have limited the Board’s discretion to target certain subsets of the housing stock, rent increases cannot be targeted to the buildings that need them most (not to mention the fact that tenants in the most distressed buildings tend to have lower incomes and are less likely to be able to afford those targeted increases). RGB rent increases will not be enough on their own to resolve the financial distress of many of these buildings.

Direct subsidies to preserve this stock will be very expensive, easily measured in the hundreds of millions of dollars, and soon into the billions of dollars each year — at a time when the City is already struggling to close significant budget gaps. Nonetheless, the City and state may need to subsidize a large portion of rent-stabilized housing to keep it from failing, and that will redirect resources from other priorities.

Broader changes to the regulatory and property tax regime that govern revenues and expenses for this housing stock might help, but none of those changes will be easy, and indirect subsidies come with measurable costs as well, even if they are not showing up in State and City budgets. It will be difficult otherwise to reduce costs, such as insurance and interest on mortgages, as these are set by third parties over whom government actors have relatively little control.

There are no easy answers to this growing problem. But as the politics heat up, it is important that the public understand the basic nature, power and obligations of the Rent Guidelines Board. All New Yorkers should be concerned about the long-term viability of the rent-regulated housing stock, and we are all on notice that it is at risk. This part of the housing stock is a precious resource for a city rightly committed to socio-economic diversity, and we should all look for a path forward to preserve it.

We assume that the mayor will work hard to make good on his promise to freeze the rent. If he doesn’t, many of those who voted for him will see it as a betrayal. If the Board, following its mandate, agrees, preserving the stabilized stock will require partnering with the governor, the Legislature and the City Council to address the impending financial crisis facing a large swath of this vital source of housing.

Housing Stability in the Mamdani Administration

By Phillip Capper, Wellington, NZ – 143rd. St., Bronx, NY, 2/08, CC BY 2.0

I am looking forward to the discussion tonight on Housing Stability in the Mamdani Administration, hosted by the Urban Design Forum. While it is sold out, we will be discussing “what a potential rent freeze may look like under the Mamdani administration” and I am sure there will be some good reporting on this topic over the coming weeks and months. The Forum writes,

As living costs continue to rise, Mayor-elect Mamdani has proposed freezing rents on stabilized apartments as a way to support tenants and protect housing stability. At the same time, critics warn that such measures could make it harder for building owners—particularly those managing older buildings with thin margins—to maintain safe, livable homes.

We’ll begin with an overview presentation by Mark Willis of the Furman Center, followed by a panel with Oksana Mironova, Emily KurtzDavid Reiss, and Thomas Yuon how the next administration can promote tenant stability and preserve affordable housing.

What strategies can preserve deep affordability while ensuring stabilized buildings remain financially sustainable?

Understanding NYC’s Rent-Stabilized Housing Stock

I will be moderating an NYU Furman Center Policy Breakfast on NYC’s Rent-Stabilized Housing: Understanding Different Segments of the Stock and Why It Matters on November 19th. The link to register is here.

Nearly one million apartments in New York City are rent-stabilized. In 2023, the median rent among rent-stabilized tenants was about $1,500, compared with $2,000 for market-rate renters. These units play a central role in maintaining housing affordability across the city, yet they are often discussed as a single, uniform category.

Our policy breakfast will explore the diversity among buildings with rent-stabilized units, spanning older pre-1974 buildings and newer developments regulated because they received public financing or property tax reductions. Panelists will discuss how these differences shape the challenges and policy considerations facing the rent-stabilized housing stock today. The session aims to deepen understanding of the current landscape and to ground debate on what tailored interventions may be needed to preserve the affordability and quality of this essential part of New York City’s housing supply.

Micro Apartments and The Housing Crisis

The NYU Furman Center has posted 21st Century SROs: Can Small Housing Units Help Meet the Need for Affordable Housing in New York City? The policy brief opens,

Throughout much of the last century, single-room occupancy (SRO) housing was a commonly available type of low-rent housing in New York City, providing housing to people newly arrived in the city, low-income single New Yorkers, and people needing somewhere to live during life transitions. SRO units typically consisted of a private room with access to full bathroom and kitchen facilities that a renter shared with other building occupants. As the city fell onto hard times, so did SRO housing. During the second half of the last century, many SROs came to serve as housing of last resort, and policymakers enacted laws limiting their construction and discouraging the operation of SRO units. Many SROs were converted to other forms of housing, resulting in the loss of thousands of low-rent units in the city.

New research and analysis from the NYU Furman Center addresses the question of whether small housing units (self-contained micro units and efficiency units with shared facilities) can and should help meet the housing need previously served by SROs. In this policy brief, we present a summary of the paper, 21st Century SROs: Can Small Housing Units Help Meet the Need for Affordable Housing in New York City? We provide an overview of the potential demand for smaller, cheaper units, discuss the economics of building small units, analyze the main barriers to the creation of small units that exist in New York City, and suggest possible reforms that New York City can make to address these barriers. (1)

The policy brief makes a series of recommendations, including

  • reducing density limitations for micro units near transit hubs
  • permitting mixed-income and market-rate efficiency units
  • creating a government small unit program to promote the construction of micro apartments

There is no doubt that the lack of supply is a key driver of the affordable housing crisis across the country. Small units should be part of the response to that crisis, not just in New York City but in all high-cost cities.

Rental Housing Landscape

A Row of Tenements, by Robert Spencer (1915)

NYU’s Furman Center released its 2017 National Rental Housing Landscape. My two takeaways are that, compared to the years before the financial crisis, (1) many tenants remain rent burdened and (2) higher income households are renting more. These takeaways have a lot of consequences for housing policymakers. We should keep these developments in mind as we debate tax reform proposals regarding the mortgage interest deduction and the deduction of property taxes. When it comes to housing, who should the tax code be helping more — homeowners or renters?

The Executive Summary of the report reads,

This study examines rental housing trends from 2006 to 2015 in the 53 metropolitan areas of the U.S. that had populations of over one million in 2015 (“metros”), with a particular focus on the economic recovery period beginning in 2012.

Median rents grew faster than inflation in virtually every metro between 2012 and 2015, especially in already high rent metros.

Despite rising rents, the share of renters spending more than 30 percent of their income on rent (defined as rent burdened households) fell slightly between 2012 and 2015, as did the share spending more than 50 percent (defined as severely rent burdened households). Still, these shares were higher in 2015 than in 2006, and far higher than in earlier decades.

The number and share of renters has increased considerably since 2006 and continued to rise in virtually every metro from 2012 to 2015. Within that period, the increase in renter share was relatively larger for high socioeconomic status households. That said, the typical renter household still has lower income and less educational attainment than the typical non-renter household.

Following years of decline during the Great Recession, the real median income of renters grew between 2012 and 2015, but this was primarily driven by the larger numbers of higher income households that are renting and the increasing incomes of renter households with at least one member holding a bachelor’s degree or higher. The real median income of renter households with members with just a high school degree or some college grew more modestly and remained below 2006 levels in 2015.

Thus, the recent decline in the share of rent burdened households should be cautiously interpreted. The income of the typical renter household increased as the economy recovered, but part of this increase came from a change in the composition of the renter population as more high socioeconomic status households chose to rent their homes.

For almost every metro, the median rent in 2015 for units that had been on the market within the previous year was higher than that for other units, suggesting that renters would likely face a rent hike if they moved. The share of recently available rental units that were affordable to households earning their metro’s median income fell between 2012 and 2015. And in 2015, only a small share of recently available rental units were affordable to households earning half of their metro’s median income. (3, footnote omitted)

Poverty in NYC

NYU’s Furman Center has released its annual State of New York City’s Housing and Neighborhoods along with a focus on Poverty in New York City. The State of the City report is always of great value but each year’s focus is where we get to see the City in a new light. This year is no different:

In New York City in recent years, rents have risen much faster than incomes. The pressures of rising housing costs may be greatest on those with the fewest resources—people living in poverty. New York City has a larger number of people living in poverty today than it has since at least 1970. This sparks a range of questions about the experience of poverty in New York City that we address in this year’s State of New York City’s Housing and Neighborhoods Focus. Who in New York City is poor today? Where do they live? What are the characteristics of the neighborhoods where poor New Yorkers live? Are poor New Yorkers more likely to be living in areas of concentrated poverty than they were in the past? How, if at all, do the answers to each of these questions differ by the race, ethnicity, and other characteristics of poor households?

Though the share of New Yorkers living in poverty has been relatively constant over the past few decades, there was a drop at the end of the last decade and then an increase in 2011–2015. Poverty concentration—the extent to which poor New Yorkers are living in neighborhoods with other poor New Yorkers—followed a similar trend, dropping in 2006–2010 and increasing again since then. The neighborhood of the typical poor New Yorker varies substantially from that of the typical non-poor New Yorker, but those disparities are largely experienced by black and Hispanic New Yorkers living in poverty. The typical poor Asian and white New Yorkers live in neighborhoods that do better on the measures we examine than the neighborhoods of the typical non-poor New Yorker. We also find that neighborhood conditions vary significantly based on the level of poverty in a neighborhood. Higher poverty neighborhoods have higher violent crime rates, poorer performing schools, and fewer adults who are college educated or working. And, poor New Yorkers are not all equally likely to live in these neighborhoods. Poor black and Hispanic New Yorkers are much more likely to live in higher poverty neighborhoods than poor white and Asian New Yorkers. Children make up a higher share of the population in higher poverty neighborhoods than adults or seniors. (1, footnotes omitted)

Policymakers should have a lot to chew over in this report. Let’s hope they give it a read.
