The new owner of a 1947-built Orchard Drive home is seeking permission from the town to construct a second floor over part of the house. Though it does not predate the New Canaan Zoning Regulations, the 1,769-square-foot, four-bedroom Cape Cod-style home at 111 Orchard Drive encroaches on the front yard setback by mere inches in two places, according to a recently completed survey of the property, officials say. The .35-acre property, located in the “A Residential” zone, was purchased for $775,000 in October, tax records show. Under the New Canaan Zoning Regulations, a nonconforming structure in the zone may only be enlarged if it complies with the regs or gets a variance from the Zoning Board of Appeals (see page 158 here). The ZBA is scheduled to take up the application at its regular meeting Monday night.
