In Haaf v. Zoning Hearing Board of the Township of Weisenberg, 155 Pa. Commw. 608, 625 A.2d 1292 (Pa. Cmwlth. 1993), the zoning hearing board granted a variance for the construction of an advertising sign and, thereafter, the zoning officer issued a permit for a sign not to exceed 45 feet in height. Haaf learned of the issuance of the permit at a township planning commission meeting on December 29, 1987. On February 8, 1988, several objectors, including Haaf, appealed to the Board, challenging the validity of the permit to the extent it allowed a sign 45 feet high. The zoning hearing board determined that the appeal was timely because it was filed within 30 days of the objectors' receipt of a copy of the board decision and a copy of the permit. The Court reversed, concluding that the appeal was not timely because Haaf knew about the issuance of the building permit on December 29, 1987, which triggered the 30-day appeal period. Id. at 1296.
