Your OFM Guide to PLUS

PLUS is the new central platform customers can access through the Fairfax County website to complete their zoning, building, permitting, or other land development processes. PLUS is launching through a series of four releases, each adding new features and functionality to achieve increased reliability and capabilities in zoning evaluations, plan review, approval, permitting and inspections.


Please note: During the transition, PLUS and ProjectDox will be unavailable end of day Friday, Oct 21, while FIDO and PAWS will only be available in view mode. Please plan ahead if you are trying to start a new project or complete one that has been in the system.

Due to the Release 4 PLUS outage, customers will not be able to submit new applications, view submitted applications, schedule inspections, make payments or upload plan documents.

The review and processing of applications submitted in October and November may take longer than usual due to the outage. Please call the Office of the Fire Marshal at 703-246-4803 for assistance

PLUS will replace all legacy systems (FIDO, PAWS and ProjectDox) beginning Monday, Oct. 31, 2022. For further questions or assistance, customers should call OFM staff at the numbers listed in the PLUS Support section below.


PLUS can be used to track current applications, make changes to these applications or to start new application.

Please Note: Microsoft Edge is the supported browser for PLUS

The new centralized PLUS platform has several customer benefits:

  • Customers no longer need to learn multiple platforms to conduct business with land development agencies.
  • Customers have one account in PLUS and do not need multiple accounts to interact across agencies.
  • The user-friendly system provides a more intuitive interface between the county and its customers.
  • A more robust search function is available for customers and county staff for use within the platform.
