Bill > HB1466

This bill establishes a statewide policy to promote and encourage the creation of accessory dwelling units (ADUs) on properties with single-family detached homes to help meet Maryland's housing needs. By October 1, 2026, local legislative bodies must adopt laws authorizing ADU development with specific requirements. An ADU is defined as a secondary dwelling unit on the same lot as a primary single-family detached home, not exceeding 75% of the primary home's size and subordinate in use. The bill prohibits local jurisdictions from imposing unreasonable restrictions on ADU development, such as significant cost increases or outright prohibitions. Local laws must exclude ADUs from density calculations and provide for their construction while meeting public health, safety, and welfare standards. The bill also modifies homeowners association rules to allow ADUs to be treated as separate lots for voting and assessment purposes, and prevents deed restrictions or covenants from unreasonably limiting ADU development. These changes aim to increase housing availability and flexibility by making it easier for homeowners to create additional dwelling units on their properties.
