In a run-down section of city street in Niagara Falls, N.Y. -- flanked by abandoned homes and across from a shuttered hospital -- a dilapidated old dormitory for nurses is getting a new start as transitional housing for homeless women and their children. The building's rehabilitation is being made possible, in large measure, by the efforts of University at Buffalo law students attracted to an unglamorous, roll-up-your-sleeves niche of law practice known as affordable housing.
