Affordable Dwelling Unit Program

About the ADU Program

Loudoun County’s Affordable Dwelling Unit (ADU) program provides newly constructed, affordable rental and for-sale housing for income-eligible citizens who live and work in the county as the first priority.

ADU staff is conducting virtual intake sessions instead of in-person sessions. If you have been scheduled for an intake session, directions on how to participate virtually will be emailed to you in advance of the intake session. 

ADU Purchase Program

ADU Rental Program     

  • The ADU Rental Program enables eligible non-homeowners the opportunity to rent an apartment from a participating apartment complex, at a rent below that of similar units at the complex. 
  • ADU rental units are located throughout Loudoun County. Average rental rates range from approximately $630 to $1,300 depending on the type and size of the unit, not including the cost of utilities. 
  • Learn more and find out if you are eligible for the  ADU Rental Program.
