Each year, the Department of Housing Preservation and Development (HPD) designates severely distressed multiple dwellings for participation in the Alternative Enforcement Program (AEP). HPD is required by law to submit and post an annual summary report of all AEP buildings. This dataset includes all buildings selected for participation in the AEP and the current status of the building in the program.

Pursuant to New York City’s Housing Maintenance Code, the Department of Housing Preservation and Development (HPD) collects information on multiple dwellings in New York City, and other buildings that fall under its jurisdiction. HPD’s Buildings Open Data covers all buildings which meet any of the following criteria:

a. HPD has required the owner to register the building under the Housing Maintenance Code (HMC) b. HPD has initiated a litigation action under the HMC c. HPD has received a complaint for the building d. HPD has initiated a work order for the purposes of emergency repair, demolition, or the Alternative Enforcement Program (AEP) for the building e. HPD has added the property to the AEP program

Buildings are identified by a BuildingID.
