HB1466 mandates that legislative bodies of certain Maryland counties and municipalities adopt local laws authorizing accessory dwelling units (ADUs) on lots with a single-family detached dwelling as the primary unit, while prohibiting restrictions that limit ADU development or rental. It exempts ADUs from density calculations, allows homeowner associations to treat ADUs as separate lots for voting and assessments, and promotes ADUs to address housing needs.
The Maryland State House of Delegates passed HB1466 on March 17, 2025, by a vote of 138 to 1. We have assigned pluses to the nays because this legislation expands government regulation of private property, and imposes state mandates on local zoning. It overrides local government, and compels property owners to conform to centralized housing policies, expanding bureaucratic overreach in private property.
