What's New?

Over the last year Howard County has been undertaking an extensive and multifaceted upgrade of ProjectDox. This has included migrating to a cloud-based server and updating the software and interface. The next phase of this upgrade is taking place on October 2nd and will see efficiencies made to our Development Workflow (S, SDP, F, ECP, SP, W&S plans), along with the addition of two new workflows that will see our Alternative Compliance and Redlining processes hosted and performed in ProjectDox. Overall, changes to the current user experience for development plans will be minimal. Unlike past updates, there will be no system downtime. The website URL will remain the same.

This latest upgrade will be most noticeable in several ways:

  • All drawings submitted to ProjectDox for review must be in PDF format. Drawings in other formats, such as DWG, will not be accepted by the system.
    • For more information regarding the Review Comments/Reviews process for responding to plan review, please see the Applicant Quick Guide found in the "Getting Started" section of this page
  • Applicant responses to reviewer changemarks and comments are performed in a dedicated review form. Applicant changemarks and comments outside of the review response form will be disabled. Agency Staff changemarks and top-priority comments in the review form must be responded to in order to resubmit plans.
  • All applications are accessed and submitted in ProjectDox and not via our webpage. For Alternative Compliance and Redlines, in-person paper applications will no longer be accepted and required plans prints can be submitted via the appropriate drop box in the George Howard Building.

In February 2023, Howard County upgraded to ProjectDox 9.2 from 9.1, which saw changes to the user interface.

What's New in 9.2?

In November 2022, Howard County migrated ProjectDox to a cloud-based environment.
