PORTLAND — A Mercy Hospital housing program for mothers in need of substance abuse treatment and their children is expanding and moving to a new location in the city.

McAuley Residence, now seven apartments on State Street, is moving to the former home of the Children’s Hospital of Portland on High Street, where there will be 15 apartments, from studios to two-bedrooms.

The building at 68 High St. is owned by Community Housing of Maine and was recently renovated, according to a press release from Mercy.

Women who are admitted to the program, after a screening, struggle with addiction and other problems, including homelessness and domestic violence, Mercy said.

They have access to the Mercy Recovery Center, Mercy Primary Care Centers and Mercy partners for parenting and financial counseling.

The program was started 25 years ago and has helped more than 200 women restart their lives, according to the release.
