How dire is New York City’s housing shortage? City officials estimate that about 290,000 new homes would be needed right now to satisfy the unmet demand. And that number is only going to grow as more people jostle for places to live.

In the longer term, New York City will need about 700,000 homes built over the next 10 years to solve the problem, a draft report from city officials has concluded. The estimate is based on population projections, as well as the need for housing among residents who are homeless or can’t afford to live on their own.

New York City’s current housing shortage is one of the most dire on record, said the report released Wednesday by the Department of Housing Preservation and Development and the Department of City Planning. Only about 1.5 percent of the city’s rental apartments are available, and among those with asking rents of less than $1,100 a month, availability is less than 0.4 percent, it said.

The draft report, known as the city’s Fair Housing Growth Strategy, is part of a process to fulfill a 2023 City Council mandate for an estimate of the overall need for new housing. City officials plan to hold virtual briefings on Aug. 26 and Sept. 2 and seek input from the public before publishing a final version of the report in October.

The City Council mandate that led to the report preceded the election of Mayor Zohran Mamdani, who campaigned last year on a promise to make the city more affordable. Three months ago, the mayor released his plan to spend $22 billion on housing and add 200,000 affordable units in the city over the next decade. That plan did not address the city’s need for additional market-rate housing, including luxury apartments, which is a significant component of the 700,000-unit strategy.

In the new report, city officials delved into the rates of recent housing growth in different areas, designating them as low, medium or fast growers. They plan to assign nonbinding, five-year growth targets to various neighborhoods, and ask the “low growers” to start catching up. The goal is to have about 350,000 units built in the next five years while diversifying the housing stock — not just citywide, but on a neighborhood-by-neighborhood basis.

“To overcome our housing crisis, we need every neighborhood in every borough to do its part,” Dina Levy, commissioner of the Department of Housing Preservation and Development, said in a statement. “The Fair Housing Growth Strategy is a road map to a fairer and more affordable city.”

Some neighborhoods in Brooklyn and Queens along the East River waterfront have been transformed by a boom in apartment construction in the last decade. The neighborhoods of Williamsburg and Greenpoint in Brooklyn were labeled “high growers” in the report and were assigned targets of increasing their supplies of housing by about 10 percent by 2030.

But other areas where city officials would like to see similar growth rates are filled with single-family homes and have experienced relatively little growth in recent years. As an example, the report cites the Mid Island neighborhood of Staten Island, which has added homes at a rate well below 1 percent. It calls for Mid Island to add more than 5,000 homes by 2030, which would mean a tenfold increase in its growth rate.

To overcome the factors that have led to a concentration of low-income housing in certain neighborhoods, the report calls for the city government to employ strategies such as providing financing to spur development of affordable housing in low-growth areas.

The report also suggests making zoning changes to allow for more development in low-growth neighborhoods, and encouraging recipients of housing vouchers to choose the neighborhoods that suit their needs rather than “telling them where they should or should not live.” It also recommended investing in amenities like parks and community facilities to make the low-growth areas more appealing to lower-income residents, the report said.
