County Council Adopts New Rules for Accessory Dwelling Units

On July 23, 2019, the Montgomery County Council adopted Zoning Text Amendment 19-01 (ZTA 19-01) regarding “accessory dwelling units” (ADUs).  When the ZTA goes into effect on December 31, 2019, it will result in substantial changes to the rules that govern ADUs.  An ADU is a second dwelling unit located on a lot with a single-family house.  An attached ADU is one that is located inside the house, often in the basement.  A detached ADU is one that is in an accessory building in a rear yard (e.g., a converted garage, a granny pod, a pre-fabricated unit). 

The most significant change in the rules for ADUs is that, for the first time, detached ADUs will be allowed in “small lot” neighborhoods like the Town.  Under the new county rules, there are no setback requirements for detached ADUs constructed in older buildings.  In the Town, older garages often sit on or very close to the side and/or rear property lines.  Other substantial changes include: ADUs will be allowed as a limited use on all properties; both attached and detached ADUs will be allowed as part of new construction; and no off-street parking spaces will be required for ADUs.  Read more about the changes here.

The Town can adopt rules to govern detached ADU setbacks and screening.  But before considering any measures, we would like to hear views from residents on this matter.  Please write to the Town Office if you have interest or questions.
