Saw on The Annandale Blog that the county is taking comments from residents on changes to the zoning rules. A little confusing that accessory dwelling units in single family homes are now to be referred to as accessory living units. Work on this started under Sharon Bulova and I think the board will be voting on it soon. Meetings are happening this week and some will be available to stream.
