Nettleton v. Zoning Board of Adjustment

In Nettleton v. Zoning Board of Adjustment, 574 Pa. 45, 828 A.2d 1033 (2003), the landowner sought permission for a two-story vertical addition to a dimensionally nonconforming building in order to increase a residential use permitted by right in the zoning district. Therefore, the issue presented was whether the expansion was permitted pursuant to Code 921.03.D.1, having to do with the enlargement and expansion of nonconforming structures.
