[Amended 4-4-1977 by Ord. No. 77-41]
Subject to other provisions of this chapter, all exceptions or variances granted by the Zoning Board of Adjustment or Planning Board, pursuant to §
38-16A(3) and
(4) hereof, shall expire one year from the date granted unless the applicant secures a building permit and commences necessary construction within that period and shall expire two years after the date granted unless the applicant has completed said construction, alteration or improvement within said two-year period. If the work has not commenced within one year or if all work is not completed within two years, the variance and any permit issued pursuant thereto shall be null and void. Where the applicant fails to complete all necessary work within two years of the grant of the variance, the Zoning Officer shall give the applicant 10 days' notice in writing that he shall enforce the two-year limitation and revoke the applicant's building permit. However, for good cause shown, the Zoning Board of Adjustment or Planning Board, upon written application, may extend the time limitations in this section. Upon failure of the applicant to demonstrate good cause for an extension of the time to complete all necessary work or a finding by the Board that conditions have materially altered or changed since the date the variance was granted, the Board shall declare said variance null and void. Construction is deemed to have commenced when the applicant has performed substantial physical work to commit the land to the improvement or alteration which was the subject of the variance, beyond mere preparatory work, such as surveying or excavation, and has shown an intent to continue the construction.
