What is an Accessory Apartment?
An accessory apartment is a separate living unit located on a residential lot with an existing single-family dwelling. An accessory apartment includes one or more rooms used to provide living, sleeping, cooking, and sanitation, located within a single-family dwelling (interior apartment) or in a detached structure on the same property (exterior apartment). Accessory apartments are subordinate in size to the primary dwelling and may be used as accessory homestays, rental units, family-caregiver suites, private recreation spaces or guest houses/rooms.
How do I know whether I can develop an Accessory Apartment?
Review the Accessory Apartment sections, Article 25.3.1 and Article 25.3.2 of the Round Hill Zoning Ordinance, and check below for Accessory Apartment Standards. You can also call the Town Office to speak with the Staff regarding specific regulations that may apply to your project, as well as other options that are available to you to help you achieve your goal.
