Fort Point neighborhood residents and a Boston city councilor are seeking details from Healey administration officials on the state’s consideration of a Fort Point office building to serve as a temporary migrant shelter.

The 24 Farnsworth St. property includes a 92,000-square-foot office building owned by the Unitarian Universalist Church.

The Healey administration opened an overflow shelter for 400 migrants at Roxbury’s Cass Recreation Center this week, responding to a growing number of people who had been living at Logan International Airport while awaiting a spot at a shelter. The Roxbury site will be used through May 31, administration officials said this week.

But the Roxbury shelter is already nearing capacity, Boston Mayor Michelle Wu said Wednesday, prompting state officials to seek additional locations.

City Councilor Erin Murphy told WBZ she wants assurances that the Fort Point property has sufficient facilities for housing.

“I’m hearing there might be one bathroom here and no showers or one shower, so definitely we’ll need to make this a space that is safe,” told WBZ.

The church acquired the brick-and-beam office building in 2015 for $25.5 million following a repositioning project by The Davis Cos. of Boston. The church had previously signed a 10-year lease for office space with an option to purchase the property, as it relocated its headquarters from 25 Beacon St.

A church spokesperson told the Boston Globe the shelter would be a short-term use of the building, but the plans have not been finalized.
