Provided: It shall not be necessary to record in the Ordinance Book the full text of any ordinance where there is a specific provision in the laws of Pennsylvania permitting adoption and recording by reference, or in the case of any ordinance adopting, with or without amendment or modification, any standard building, plumbing, electrical, housing, or other technical code complete in itself, for the regulation of any trade, occupation or line of activity or undertaking, but in the latter cases it shall be necessary only to record the ordinance adopting the same by reference and indicating the Municipal office where the complete code or ordinance shall be available. Provided further: Whenever an ordinance shall be specifically amended or repealed, the City Clerk shall cause a notation to that effect to be made in the Ordinance Book at the location where the recording of such ordinance shall commence.
