As part of New York City's Open Data Policy, the Department of Housing Preservation and Development (HPD) will use this page to post or link to various data we collect in the course of doing business. Among other things, this will enable computer programmers and app builders to create applications and tools that could improve access to public information and put it at the fingertips of tenants, landlords, developers, elected officials, housing advocates, and other interested parties.
Please note that HPD's information sets are generally large. The information files are in a standard XML format. The XML format is defined in schema files that accompany the information files. There is also a file explaining the information we're providing and the schedule for new releases. For each information set we're making available, we distribute two zipped files. The first is a spreadsheet detailing what data we are making available and how that data is organized (schema files). The second file contains the information. For questions about HPD's Open Data, contact us at OpenData@hpd.nyc.gov.

Housing New York Units by Building
HPD reports on buildings, units, and projects that began after January 1, 2014 and are counted towards the Housing New York plan. The Housing New York Units by Building file presents this data by building, and includes building-level data, such as house number, street name, BBL, and BIN for each building in a project. The unit counts are provided by building. Please see the Housing New York Units by Building documentation for more details about this dataset.
Housing New York Units by Project
HPD reports on buildings, units, and projects that began after January 1, 2014 and are counted towards the Housing New York plan. The Housing New York Units by Project file presents this data by project, and includes project-level data, such as senior units, but does not include building-level data. The unit counts are provided for each project, rather than by building. Please see the Housing New York Units by Project documentation for more details about this dataset.

Pursuant to New York City's Housing Maintenance Code, the Buildings dataset contains information collected by HPD on multiple dwellings in New York City, and other buildings that fall under its jurisdiction. Please see the Buildings documentation for more details about this dataset.
The Charges dataset collection contain information on work orders created through HPD's Emergency Repair Program, Alternative Enforcement Program, and Demolition programs. Note that the Charges collection is comprised of three different datasets – Open Market Order Charges, Handyman Work Order Charges, and Invoices for Open Market Order Charges. The Fee Charges dataset contains information on fees assessed against properties for inspections, false certifications, etc. Please see the Charges documentation for more details about these datasets.
The Housing Maintenance Complaints dataset contains complaints that are made by the public through the 311 Citizen Services Center, Code Enforcement Borough Offices or the internet for conditions which violate the New York City Housing Maintenance Code (HMC) or the New York State Multiple Dwelling Law (MDL). Each complaint is associated with one or more housing maintenance problems received by HPD. The Complaint Problems dataset is a breakdown of those complaints into problems, listing each problem in a single call or transaction. Please see the Complaints documentation for more details about these datasets.
Housing Litigation Files
HPD's Housing Litigation Files dataset includes Housing Litigation Division's (HLD) actions in Housing Court against owners of privately-owned buildings to enforce compliance with the housing quality standards contained in the New York State Multiple Dwelling Law and the New York City Housing Maintenance Code. HLD attorneys also represent HPD when tenants initiate actions against private owners. HPD is automatically named as party to such actions. The goal of these court proceedings is to obtain enforceable Orders to Correct, Civil Penalties (fines) and Contempt Sanctions, compelling owners to comply with the Housing Code.
Pursuant to New York City's Housing Maintenance Code, the Multiple Dwelling Registrations dataset contains registration information from owners of residential rental units. Owners are required to register if they own residential buildings with three or more units or if they own one- or two-family homes and neither they nor members of their immediate family live there. The Registration Contacts dataset contains information about organizations or individuals listed on a Multiple Dwelling Registration form. Please see the Registration documentation for more details about these datasets.
Speculation Watch List
Local Law No. 7 of 2018 requires HPD to evaluate certain sales of select rent-regulated multiple dwellings for potential inclusion on the Speculation Watch List. HPD measures the potential for speculation by comparing a property’s capitalization rate (defined as a property’s net operating income divided by its sales price) to the median capitalization rate of similar buildings sold in the same borough. HPD places properties sold with capitalization rates below their borough’s median on the Speculation Watch List.
Pursuant to New York City’s Housing Maintenance Code, HPD issues violations against conditions, in rental dwelling units and buildings, that have been verified to violate the New York City Housing Maintenance Code (HMC) or the New York State Multiple Dwelling Law (MDL). The base data for this file is all violations open as of October 1, 2012. All violations issued since that date have been added to the file and the current status of the violation is provided. The Violation Files dataset is updated daily with status changes and newly issued violations. An open violation is a violation which is still active on the Department records; obtain only open violations by filtering the Violation Status column for "Open." See the "Current Status" column determining how to filter within open violations for a more detailed current status of open violation. Please see the Violation Files documentation for more details about this dataset.
Alternative Enforcement Program Files
On or around January 31st of each year, HPD designates severely distressed multiple dwellings for participation in the Alternative Enforcement Program (AEP). The Alternative Enforcement Program dataset contains all buildings selected for participation in AEP and the current status of the building in the program. HPD is required by law to submit and post an annual summary report of all AEP buildings. Please see the AEP data dictionary and webpage for more information.

Median Asking Rents
For purposes of information required to be included in written buyout offers as provided under Administrative Code § 27-2004(f-2), HPD has determined that there is not statistically significant and representative data available on median rents to be reported at this time. Therefore, the information regarding median rents otherwise required to be included in written buyout offers under § 27-2004(f-2)(6) is not required to be included at this time.
