When a special exception application involves land development and/or subdivision approval, any special exception approval granted by the Zoning Hearing Board shall be governed in a manner consistent with Section 917 of the Pennsylvania Municipalities Planning Code, 53 P.S. § 10917, which provides that the applicant shall be entitled to rely upon the ordinances in effect at the time of special exception approval if the applicant submits land development and/or subdivision plans within a period of six months from the date of such special exception approval. A special exception approval that does not involve or require land development and/or subdivision approval and variance approval shall expire if the applicant fails to obtain a building permit or a use and occupancy permit, as the case may be, within one year from the date of the Zoning Hearing Board's decision.
