North Beach has its own municipal accessory-apartment rules. See the current 5,000-sq-ft lot minimum, 800-sq-ft detached cap, parking and owner-occupancy rules, the Calvert County permit split, and the 2026 HB 1466 transition.

Kent County’s current ADU framework allows one accessory dwelling in several County zoning districts. See owner-occupancy, parking, rental, permit and town-jurisdiction rules, plus the remaining HB 1466 parking question.
