DOB Launches Certifi For Online Management Of Certificates Of Occupancy

Certifi Page

Last week, DOB proudly introduced a new digital platform for the processing and tracking of online applications, Certifi. Debuting October 23, 2023, the new platform delivers a valuable improvement in our processes, enhancing our service delivery and improving the customer experience by centralizing and demystifying the process of obtaining Certificates of Occupancy (C of Os). Using their Access DC login, users can see the status of their application at a moment’s notice, and will be prompted by system-generated notifications to upload documentation or submit payment.

New C of O applications are now only processed in Certifi. In-progress applications that were active prior to the introduction of Certifi must be completed and C of Os issued no later than December 4, 2023. Otherwise, customers will be required to submit a new application using Certifi.


DOB’s new online platform allows for the centralized submission, tracking, and issuance of C of O applications.

  • Our new platform allows users to see at a glance how different DOB reviews require certain documents, clarifies and simplifies the application process by allowing users to move through a step-by-step path based on their project’s needs, and increases transparency and efficiency of the review process for applicants and DOB reviewers.
  • In the District of Columbia, we want to encourage responsible growth and development, but we also want to ensure that construction happens safely. This platform allows us to continue prioritizing safety while enhancing the customer experience. Certifi is a clear program that allows customers to hold DOB accountable and enables us to boost our processing capacity.

The new system offers a completely digitized application process, increased collaboration between internal teams and customers, and ultimately faster issuance times due to built-in system notifications and triggers to help drive the process to completion.
