Bill > SB891

This bill establishes a comprehensive state policy to promote and encourage the creation of accessory dwelling units (ADUs) on properties with a single-family detached dwelling. By October 1, 2026, local legislative bodies must adopt laws authorizing ADU development, which are defined as secondary dwelling units that are on the same lot as a primary single-family dwelling and not larger than 75% of the primary unit's size. The bill requires local jurisdictions to create policies that facilitate ADU development while ensuring public health, safety, and welfare standards are met. Key provisions include excluding ADUs from density calculations, providing flexibility in parking requirements, and preventing unreasonable restrictions from homeowners associations or property deed restrictions that would prohibit or significantly increase the cost of creating an ADU. The legislation aims to address housing needs by making it easier for homeowners to create additional living spaces on their properties, such as converting existing structures or building new, smaller units. The bill will take effect on October 1, 2025, and applies to charter counties and Baltimore City, with the goal of increasing housing options and affordability across Maryland.
