Find Building Data

Using tools like the Building Information System (BIS) and the DOB NOW Public Portal, you can review the history of any building in New York City. You can find violations, permits and complaints that were reported. The building history also shows the current status of the information as active or resolved.

Please see below for information about the records available in each system:

  • Use BIS to...
    The Building Information System (BIS) enables you to easily see the latest developments at construction sites in your neighborhood and around New York City. You can search for general information on a property in the City including recorded complaints, violations, actions, applications, and inspections. The database includes jobs and filings from the Buildings Information System (BIS) only. It does not include filings submitted in DOB NOW. Information searches about tradespeople licensed by DOB is also available in BIS.

  • Use DOB NOW to...
    DOB NOW allows you to submit job filings electronically. Current DOB NOW job filings include antenna, curb cut, electrical, elevator, fence, limited alteration application, place of assembly, sidewalk shed, sign and supported scaffold. Compliance filings for boilers, elevators and façades are also part of the system. Additional work types will be added in the coming years.

    The DOB NOW Public Portal contains information on applications submitted in DOB NOW, compliance filings for boilers, elevators and facades, and violations issued to property owners for failing to file annual boiler inspection reports and elevator inspection/test reports. See the DOB NOW Public Portal FAQs for more information.

  • Use Zoning Diagrams to...
    Architects and Engineers are required to submit simple, 3D representations of new buildings and enlargements. These diagrams are available through Building on My Block and allow you to view visual depictions of major construction projects in your neighborhood.

  • Use the After Hour Variance Map to...
    An after-hours variance (AHV) permit is required to perform construction work in New York City before 7:00 am, after 6:00 pm, or on the weekend. The After Hours Variance Map provides you with a tool to confirm whether construction projects on their block have the proper permits to work at night and on weekends.
