Green v. Zoning Board of Adjustment

Opinion by

Judge Craig,

Dr. and Mrs. Martin Green appeal an order of the Court of Common Pleas of Allegheny County which upheld a decision of the City of Pittsburgh Zoning Board of Adjustment granting an occupancy permit for four dwelling units in the landowners’ building1 at 623 North Negley Avenue, but denying a permit *471for a dentist’s office on the first floor of that main building. We must determine2 whether the zoning board correctly concluded that a dental office use of the property lost whatever legitimate status it may have had when Dr. Green moved his residence from the premises in 1953.
