For more than 30 years, my neighbors, a mother-daughter team, have run an opera-singing school out of their apartment. When our building converted to a co-op years ago, home businesses were abolished. But the opera school was grandfathered in. The mother and daughter were once grandes dames of the opera world. The lessons they give out of their apartment are very loud. I understand a pet being grandfathered in, but an opera-singing business? How can this be?
