BOSTON (WPRI) — A nine-month cap on families entering Massachusetts’ emergency shelter system will soon go into effect, after the state reported an influx in migrants over the last year.

On Wednesday, Gov. Maura Healey announced 90-day notices will start going out to families in the shelter system in July. The administration plans to limit the number of notices to 150 families a week.

Massachusetts is the only state in the country that has a right to shelter law, which was established in the 1980s to offer shelter to families and pregnant women.

But over the last year, the Healey administration said it has seen an increase in migrants, many from Haiti who are fleeing violence. Hotels, airports, and even a prison have all been identified as temporary housing for migrants entering the state.

In the fall of 2023, Healey announced a cap on the number of families in the emergency shelter system, at 7,500.

Still, families remained on the waiting list, leading to a push for a cap that reached the State House. In April the General Assembly passed a nine-month limit on families in the shelter system.

On Wednesday, the Healey administration laid out the the policy affecting all families within the emergency shelter system, about half of whom are homeless Massachusetts families, according to the governor’s office.

“This policy is a responsible measure to address the capacity and fiscal constraints of our state’s emergency assistance system,” Healey wrote in a statement Wednesday.

Families will be able to apply for up to two 90-day extensions, which can be granted for reasons ranging from having a baby to being in a job-training program. People can also apply for a hardship waiver.

Wednesday’s announcement also gave insight into how many migrants have received work authorizations, a challenge Healey has repeatedly called on the federal government to address.

According to the press release, 3,716 immigrants have applied for work authorizations since November and “it is expected the vast majority have been approved.”

The administration also announced progress in helping people exit the shelter system. According to data provided by the state, the number of families leaving Massachusetts went from 168 in November to 331 in May.

The nine-month policy is expected to remain in effect until the number of families in the shelter system gets below 7,500.
