What’s the Difference Between DOB Now Versus DOB Bis?

DOB Now and DOB BIS (Building Information System) are two systems used by the New York City Department of Buildings (DOB) for managing various aspects of building and construction activities. Here are the key differences between the two:


  1. Modernization: DOB Now is the newer, more modern system designed to replace many of the functions of DOB BIS. It is part of an ongoing effort to digitize and streamline the operations of the DOB.
  2. Online Portal: It is an online platform that allows for electronic filing and management of various applications, permits, inspections, and compliance documents.
  3. User Interface: DOB Now offers a more user-friendly and intuitive interface compared to the older BIS system. It supports better navigation and provides a more integrated experience.
  4. Real-Time Updates: The system provides real-time updates on the status of applications, permits, and inspections, which improves transparency and efficiency.
  5. Components: DOB Now is divided into several modules, such as:
    • DOB Now: Build for construction-related filings
    • DOB Now: Safety for compliance and safety filings
    • DOB Now: Licensing for professional licensing
    • DOB Now: Inspections for scheduling and managing inspections


  1. Legacy System: DOB BIS is the older system that has been used for many years to manage building information and related activities in New York City.
  2. Scope: While still in use, DOB BIS handles a wide range of functions, including permits, licenses, complaints, violations, and inspections.
  3. Transition: As part of the modernization effort, many functions previously handled by DOB BIS are being transitioned to DOB Now. However, some functions and historical data are still accessible only through BIS.
  4. User Experience: The interface of DOB BIS is considered more outdated and less user-friendly compared to DOB Now. Navigation can be more cumbersome, and it may not offer the same level of integration and real-time updates.
  5. Access to Historical Data: BIS still serves as the repository for historical building data and records, which may not yet be fully migrated to DOB Now.

Transition and Integration

  • Gradual Shift: The transition from DOB BIS to DOB Now is ongoing, with more features and functionalities being gradually moved to the newer system.
  • Dual Usage: During this transition period, both systems are in use. Users may need to access DOB BIS for certain historical records or functionalities not yet available in DOB Now.

In summary, while DOB Now represents the future of digital building management for the NYC Department of Buildings, DOB BIS continues to serve as a critical resource, particularly for historical data and functionalities not yet transitioned.
