As part of the Greater Boston area, Medford has seen significant housing demand, and Accessory Dwelling Units (ADUs) have become an increasingly popular solution for homeowners looking to add rental income, house family members, or increase property value. Thanks to Massachusetts' statewide ADU legislation and Medford's own zoning updates, working with experienced ADU contractors in Medford, MA has never been more important.

ADUs in Medford must comply with the Massachusetts State Building Code (780 CMR) and meet specific standards for setbacks, lot coverage, and utility connections.
Given Medford's dense, established neighborhoods — from West Medford to the Hillside area — ADU contractors in Medford frequently work on the following types of units:
