City Council Approved Accessory Dwelling Unit (ADU) Policy

City Council approved ADU policy on January 23, 2021 at their regular public hearing. More information can be found here and navigating to docket item #6.

City Council amended the policy to include the following:

  • Require homeowners to maintain primary residence of the subject property at the time of ADU construction.
  • Prohibit the exclusive use of an ADU as a short-term rental.
  • Require a fee for ADU permits.
  • Require larger setbacks for taller, detached ADUs.

What's Next?

ADU policy must be adopted as an ordinance and is not law until final passage. City Council will introduce the ordinance in early March with final passage anticipated by the end of March.

Accessory Dwelling Unit Policy Recommendations

Feedback on our draft ADU policy recommendations was accepted from October 9 to November 6. Staff refined the October 9 recommendations and the amended version can be  found below. in addition to the draft proposal and feedback received. 


What are ADUs?

Accessory dwelling units (ADUs), commonly referred to as “in-law apartments” or “granny flats”, are secondary, independent living units that typically have a separate kitchen, sleeping area and bathroom. ADUs can assume different forms including basement apartments, converted garages or new structures detached from a primary residence. ADUs can:

  • Bring in rental income that helps cover housing costs for both first-time homebuyers and long-time Alexandrians at risk of being priced out of the city;
  • Provide on-site housing options for multi-generational families, caregivers for seniors and persons with disabilities, live-in childcare providers and other caretakers;
  • Enhance housing affordability for the City’s workforce, including recent graduates and young professionals.
