SOUTH PORTLAND, Maine — Lilian Vitale, a 38-year-old mother of four, hasn’t received an eviction notice — but she’s worried about it.

Vitale lives with her husband and children in a public housing complex run by Avesta Housing in South Portland. She hasn’t lost hours at the nonprofit social service agency where she works, but her husband’s hours at an assisted-living facility dropped to part time. He would take on more work, but their younger children’s daycare closed in March. Someone must watch them.
