What did the court decide in Boston Housing Authority v. Hemingway?
Answered for: Massachusetts
Therefore, we hold that in a rental of any premises for dwelling purposes, under a written or oral lease, for a specified time or at will, there is an implied warranty that the premises are fit for human occupation.
Massachusetts' highest court recognized an implied warranty that rented dwellings are fit for human occupation.
