Do I need a permit for accessory dwelling unit (adu) in Clarke County?

Permit required

Yes. In Virginia, accessory dwelling unit (adu) generally requires a permit, and Clarke County is no exception.

Building a new ADU or converting space into one is construction or alteration that requires a building permit under the Virginia USBC (13VAC5-63-80, Section 108.1). Starting July 1, 2027, Code of Virginia 15.2-2292.4 treats ADUs as a permitted accessory use in single-family zoning districts. The locality may charge an ADU permit fee of up to $500 on top of building permit fees, and may require compliance with the USBC. The 2027 law does not apply to a locality that adopted an ADU ordinance before January 1, 2026, and it does not override HOA covenants or condominium instruments. Until it takes effect, local zoning decides whether an ADU is allowed.
