Per the City of Rockville: The Mayor and Council in January initiated a public review process for changing city code and the zoning ordinance related to accessory apartments and accessory dwelling units, or ADUs. Accessory apartments are small dwelling units either located within or attached to a single-family detached residence, subject to certain criteria. The code as it stands allows such dwellings through a potentially lengthy approval process for a special exception from the Board of Appeals. Proposed code changes would allow approval by staff, subject to compliance with certain criteria, reducing processing time.
ADUs, defined as small dwellings within a detached accessory structure on a single-family lot, are not currently permitted in the city. The proposed code changes would allow approval of ADUs by staff, subject to certain criteria, as a conditional use. If approved, such units would be subject to the same inspection requirements as other rental units in the city.
