Once such amendments are approved and the revised permit is issued, it shall be deemed part of the original permit and shall be kept therewith in the official records of the Department. A revision permit shall become invalid upon expiration of the original building permit it amends. The extension provisions of Section 105.5.1 shall apply to the original building permit and shall only affect the respective revision permits to the extent that the original building permit is extended.
While applications are pending for processing and after issuance of a permit, applicants and permit holders are required to update the electronic mailing address provided in the underlying permit application as specified in Section 105.3, Items 8 and 11.
