The City of Boston has unrolled a new initiative to support homeowners interested in increasing the City's housing options by adding Accessory Dwelling Units (ADUs) to their property. This program provides a combination of financial assistance, including grants and loans, to help with the design, permitting, and construction of ADUs, according to a news release from the City of Boston.
Mayor Michelle Wu emphasized the value of ADUs in addressing Boston's housing crisis, stating, "Accessory Dwelling Units are a powerful tool in our efforts to address the housing crisis in Boston" and noted the roles they play in "maximizing property" and "contributing to the availability of housing in our neighborhoods." These financial aids come in the form of a Technical Assistance Grant, up to $7,500 for pre-construction phases, and an ADU Loan, up to $50,000 for construction costs, which carries 0% interest and is geared especially but not exclusively toward income-eligible homeowners who the Boston Home Center (BHC) pairs with a Construction Specialist to oversee their project's completion, as per the City of Boston.
Chief of Housing, Sheila A. Dillon, explained how ADUs can serve as an income source for homeowners and provide housing for family members, which shores up the city’s housing needs. To facilitate the creation of these units, the city is also piloting a new bank loan in partnership with local lending institutions that offers affordable construction financing for ADUs," said Dillon. Eligibility for this program is based on specific income and asset limits according to the City of Boston.
Complementing the funding, the City of Boston Planning Department has launched an Accessory Dwelling Unit (ADU) Guidebook, available online and across Boston Public Library branches, to provide homeowners with practical tips and designs for ADUs, Chief of Planning Kairos Shen commented on the guidebook as "a fantastic starting point" and expressed optimism about future zoning changes to make ADU construction "more flexible and affordable.” The City's zoning reforms are part of a broader strategy to increase housing options, aiding residents to utilize their properties to their fullest potential and unlock income opportunities, the guidebook features designs that, while still requiring permits, offer a direct route for residents wishing to build ADUs.
Overall, the city's multifaceted approach, which includes financial assistance, technical guidance, and a partnership with Harvard's Laboratory for Values in the Built Environment, positions Boston to effectively tackle its housing challenges by empowering homeowners and enhancing the housing stock through the strategic addition of ADUs.
