Boston is joining a multi-city lawsuit challenging the Trump administration’s attempt to withhold billions in previously-awarded funding for housing and homelessness services from communities across the country, Mayor Wu announced Monday.

“The Trump Administration is threatening to hold up nearly $48 million for Boston to tackle homelessness unless our city complies with unconstitutional Executive Orders,” said Mayor Michelle Wu. “We are joining other cities and counties across the country to protect critical funding to prevent homelessness and house families in need. Boston will not back down on making our city a home for everyone.”

The lawsuit comes in response to the Trump administration’s move to cut $3.6 billion in funding from the U.S. Department of Housing and Urban Development (HUD) to Boston and other communities unless the municipalities comply with executive orders and grant conditions.

The orders and conditions, which the city called “unrelated to housing and likely unconstitutional,” span from immigration enforcement, to DEI, to supports for transgender individuals.

The funding cuts will impact HUD’s Continuum of Care program, “the single largest source of federal funding Boston and other cities use to address homelessness,” the city said.

The program supports efforts to assist homeless and formerly homeless individuals with finding housing, health care, counseling, and other resources. With local non-profits, the city supports programs helping over 2,000 household with homelessness each year, city officials said.

The Continuum of Care funding goes to over 18 nonprofits, including Pine Street Inn, Homestart, and Casa Myrna, the City said, and programs like “permanent supportive housing for people with disabilities, rapid re-housing for those exiting homelessness, and transitional housing for survivors of domestic violence and others in crisis,” as well as employing over 125 people.

“Our nonprofit partners work every day to make sure our most vulnerable residents have the housing and the support services that they need to stabilize their lives,” said Sheila Dillon, Boston’s Chief of Housing. “The Continuum of Care federal funding is too important to be compromised by the federal administration’s unrelated policy agenda.”

Seven other jurisdictions have signed onto the lawsuit in the federal Western District of Washington, including King County, WA; the City of New York, NY; City of Columbus, OH; City and County of San Francisco, CA; and Pierce County and Snohomish County, WA.
