§ 245-7. Intent.

A. 

Within the zones established by this chapter or amendments that may later be adopted there exist lots, structures, and uses of land and strikeouts which were lawful before this chapter was passed or amended, but which would be prohibited, regulated, or restricted under the terms of this chapter or future amendment.

B. 

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 effective date of adoption or amendment of this chapter and upon which actual building construction has been diligently carried on. Actual construction is hereby defined to include the placing of construction materials in permanent position and fastened in a permanent manner except that where demolition or removal of an existing building has been substantially begun preparatory to rebuilding, such demolition or removal shall be deemed to be actual construction, provided that work shall be diligently carried on until completion of the building involved.
