About the Affordable Dwelling Unit Program

The Affordable Dwelling Unit Program supports the development of mixed-income housing in the City of Fairfax by requiring a portion of new residential units to be designated as affordable.

On June 23, 2020, the City of Fairfax Zoning Ordinance was amended to include Affordable Dwelling Unit provisions. This change was part of the City of Fairfax 2035 Comprehensive Plan recommendations to increase housing affordability.

To implement the program, City Council:

• Adopted administrative regulations to guide program operations.
• Authorized an agreement with the Fairfax County Department of Housing and Community Development to support the administration of the city's program.
