Along with Zohran Mamdani’s historic victory in last month’s elections, New York City also approved three housing-related ballot proposal. Together, these will make it somewhat easier to adjust land-use rules to allow for new housing development, by reducing the City Council’s ability to block zoning changes.
I am glad the proposals passed, for reasons similar to those laid out by Michael Kinnucan. While zoning changes are not a sufficient solution to the city’s housing problems, they are helpful — and more important, they are a necessary condition for a bigger program of public investment in housing.
Support for the proposals was shared by many, but far from all, housing and tenant advocates in the city. Debates over the proposals reflected differences on political principle — how big a voice should local as opposed to citywide officials have over land use? — as well as on economic theory — how well does the housing market fit a simple story of supply and demand? But there are also some background factual questions where the answers tend to get assumed rather than directly debated, about what kind of housing gets built in the city right now.
So in this post, I wanted to assemble some factual information about recent housing construction in New York. For convenience — and because that’s how much of the data is organized — I am defining recent as meaning the period since 2010. Some of this is assembled from various reports and publications, but the bulk of it is my own analysis of the New York Housing and Vacancy Survey (HVS).
