(A)   To avoid undue hardship, nothing in this chapter shall be deemed to require a change in the plans, construction or designated use of any building on which actual construction was lawfully begun prior to the passage of this chapter or amendment of this chapter upon which actual building construction has been diligently carried on.
   (B)   Actual construction is hereby defined to include the placing of construction materials in permanent position and fastened in permanent manner; except that where demolition or removal of an existing building has been substantially begun preparatory to rebuilding, the demolition or removal shall be deemed to be actual construction, provided that work shall be diligently carried on until completion of the building involved.
