PHP Committee Reviews ADU Zoning Changes to Meet State Law
MCCouncilJul 24, 2026
The Planning, Housing and Parks (PHP) Committee will review Zoning Text Amendment 26-06 on July 27, 2026 at 1:30 p.m., which would amend use standards for attached and detached accessory dwelling units. The amendment is required to bring county law into compliance with Maryland House Bill 1466/Senate Bill 891, passed in April 2025, which mandates local ADU authorization laws by October 1, 2026. Current county ADU provisions are inconsistent with state law in areas including permitted zones, minimum size, density calculations, setbacks, and off-street parking.
