The Planning and Land Use System (PLUS) is a new multi-agency platform for Fairfax County customers to complete their zoning, building, permitting or other land development processes online. Through PLUS, customers can conduct online transactions under the Departments of Health, Land Development Services, Fire and Rescue, Code Compliance and Planning and Development. Customers can create and submit applications online (such as building permits), pay fees, track application status, receive electronic notifications and conduct searches. PLUS replaced all legacy systems (FIDO, PAWS and ProjectDox) beginning October 31, 2022.

To use the new services on the PLUS platform, applicants must first register for a free account at PLUS Application Portal. Others can browse and search the site without logging in.
