Long Island Multifamily Housing Map
Multifamily Rental and Co-op/Condo Housing Mapped Across Long Island
The Long Island Index Multifamily Housing map provides the first and only online, bird’s-eye-view of multifamily housing across both counties, as well as a wealth of detail within each community and for each individual housing site. It visualizes rental and coop/condo locations in an easy to use format that invites you to explore your community and zoom in and out anywhere and everywhere across the island.
The map was developed by the Center for Urban Research at the CUNY Graduate Center, for the Long Island Index. It was launched in March 2016 along with a report analyzing the trends in multifamily rental construction near train stations, to gauge how well Long Island providing affordable housing stock for walkable communities.
Once you hover your mouse over the mapped housing locations or over the decade-by-decade list in the legend, the map comes alive with information and revealing geographic patterns. Here are some highlights:
- The map displays each housing location with a different color icon, corresponding to the decade in which it was built. Hover over an icon or click it to display more details such as address, number of units, and whether the property is subsidized or market rate.
- The year-built decades are listed in the map legend, showing rentals and coops/condos separately. Hover over each decade to make the corresponding map locations pop out and make the timeline of Long Island’s history of multifamily housing development come alive.
- The map also displays housing developments not yet built. These "in the pipeline" sites are mapped by expected completion date.
- Clicking on the map or searching by village/hamlet name will zoom to your community and provide local statistics on the number of properties and units, plus a list of local developments. Click or hover over the list to highlight each location on the map and display further development details.
- Other mapped information is available such as population by race/ethnicity and poverty, displayed with color-shaded Census block groups. This helps reveal demographic patterns in relation to housing availability.
- The map also shows downtown areas to pinpoint which developments were built near train stations or downtown hubs, bus and LIRR routes to show where housing is easily accessible by public transit (or not), and land use patterns by parcel including potentially developable areas in downtowns.
The interactive map provides powerful tools for housing researchers, community residents, elected officials, and the media. Whether you’re studying housing trends in Nassau or Suffolk counties, or simply curious about whether your community is prepared for a housing future within affordable reach of young adults, seniors, and families, this new online map puts information at your fingertips not found anywhere else.
