A commission tasked with studying changes to the Massachusetts emergency shelter system wrapped up its work Tuesday by approving a final report that offers few specifics but instead outlines broad themes to guide future reforms.

As Massachusetts faces a $1 billion tab in each of the next few fiscal years to house thousands of migrant and local homeless families in state-run shelters, the group of lawmakers and shelter experts voted to issue a report that calls on officials to make family homeless rare, brief, and non-recurring.

The bulk of the report includes nine “findings and recommendations” that briefly cover everything from cutting costs to streamlining operations and limiting reliance on expensive hotels and motels to moving toward a “needs-based model.”

While the document is largely unchanged from a draft commissioners debated last week, the final version does feature three new suggestions from Rep. Paul Frost, an Auburn Republican, and Sen. Ryan Fattman, a Sutton Republican.

In an appendix at the end of the 38-page report, the two conservatives pitched further cutting down the amount of time families can stay in emergency shelters from nine to six months, implementing a six-month residency requirement for shelter applications, and codifying into law shelter placement rules Gov. Maura Healey issued in August.

In a joint statement, Frost and Fattman said the inclusion of the three recommendations “are positive signs for the future of this program and the impact it can have on all residents of the commonwealth.”

“Now the call to action must fall on the legislature as we address these recommendations in greater detail at the start of the next legislative session in January to ensure that the time and effort put into this commission does not fall to the wayside,” the two lawmakers said.

Frost and Fattman have repeatedly pushed Democrats who control the House and Senate to approve a residency requirement for the shelter system, which cost taxpayers $856 million in fiscal year 2024 and is projected to top $1 billion this fiscal year, according to state data.

Lt. Gov. Kim Driscoll, who chaired the commission, previously said the goal of the final report was not “about drawing in lines in the sand but about guiding principles so that we can get some consensus.”

“Happy to better understand where those lines could be drawn from the Legislature, should they choose to take that up,” she said during a commission meeting last week.
