Maryland committee reviews accessory dwelling units legislation for increased housing affordability

Maryland's Environment and Transportation Committee convened on March 4, 2025, to discuss a pivotal bill aimed at legalizing accessory dwelling units (ADUs) across the state. Delegate Stewart presented the bill, which seeks to address Maryland's housing affordability crisis by allowing local governments to adopt ordinances that facilitate the construction of ADUs—smaller, independent living spaces on residential properties.

The bill is rooted in findings from a task force established two years ago, which concluded that ADUs could provide affordable housing options, support families, and help seniors age in place. Proponents argue that ADUs are a cost-effective solution, often cheaper to build than traditional rental units, and can generate additional income for homeowners. Notably, studies have shown that ADUs do not significantly impact parking or property values, countering common concerns raised by opponents.

During the session, various stakeholders voiced their support for the bill, highlighting its potential to mobilize homeowners and small developers to contribute to the housing supply. For instance, representatives from the Coalition for Smarter Growth and AARP emphasized the benefits of ADUs for families and the aging population, advocating for a flexible approach that accommodates local needs.

However, some local officials expressed concerns about the bill's one-size-fits-all approach, particularly in urban areas like Hagerstown, where existing infrastructure may not support increased density. They called for amendments to allow local governments more control over ADU regulations, especially regarding safety and access issues.

The committee's discussions underscored the urgency of addressing housing affordability in Maryland, with a recent poll indicating that over 80% of voters view housing costs as a significant concern. As the bill moves forward, it aims to strike a balance between expanding housing options and respecting local governance, with the potential to reshape Maryland's housing landscape for years to come.
