​​The Accessory Dwelling Unit
Policy Task Force Final Report
Is Available​

​Published ​May 31

​During the 2023 ses​sion, the Mary​land Gen​eral Assembly passed SB 382 (sponsored by Senator Mary Washington​​), which was enacted into law on May 28, 2023. The bill established the Accessory Dwelling Unit Policy Task Force (Task Force) to study the placement of accessory dwelling units (ADU) on land zoned for single-family residential use and to survey and document a representative sampling of the variety of ordinances, laws, codes, and policies regarding accessory dwelling units at the state and local level. The Task Force also studied best practices for streamlining or standardizing the local ADU application and development review process. From this analysis, the Task Force developed legislative and policy recommendations and studied the potential impacts on surrounding single-family neighborhoods, local housing markets, and neighborhood character. ​

Comprehensive Plan Housing Element Resources

MDP, in partnership with the Maryland Department of Housing and Community Development (DHCD), developed guidance in response to HB 1045 (2019) and HB 90 (2021), which require a housing element in comprehensive plans that addresses affordability and fair housing, respectively. As part of those efforts, MDP collaborated with local housing authorities and affordable housing advocates who may also serve as resources for this effort.

Task Force Pla​​​nning Process

MDP will inventory and analyze local ADU regulations in Maryland and present the results to the Task Force. As part of that effort, the Task Force  will also review professional publications and interview planners, statewide and nationally, with direct ADU experience. Outreach may also include focus groups and surveys. Through this process, the team will identify best practices, however, a subcommittee may be required to conduct more in-depth assessments of ADU issues.

MDP staff and partners will complete and present the ADU research described above, follow the presentation with questions for the Task Force, and adjust as necessary, as shown in the diagram below. MDP staff and the Task Force will repeat this iterative process throughout the Task Force’s tenure. Staff will expand upon preliminary research and develop additional research questions at the Task Force’s direction. Later stages of the process will transition from a focus on research to Task Force recommendations and final report content.
