D. When, before the effective date of this Zoning Ordinance, a complete application has been filed for an improvement location permit for a building or structure which conforms to all applicable regulations in effect prior to the effective date of this Zoning Ordinance, the building or structure may be completed in accordance with the plans on the basis of which the application was submitted, subject to the provisions of Section
5 of these regulations. Upon completion, said building or structure may be occupied for the use which was specified on the improvement location permit application, provided said use at the time of application was classified as permitted, or if classified as a special exception, had been approved by the Board of Zoning Appeals. Provided, also, if the use originally intended no longer complies with all requirements of this Zoning Ordinance such use shall be a lawful nonconforming use subject to the nonconforming use provisions of Section
2 of this Ordinance or, alternatively, as a special use subject to the special exception provisions of Section
3 of this Ordinance. However, in the event that said application or permit expires or is suspended or revoked in accordance with Section
7 of this Ordinance, any new permit application that is submitted after the effective date of this Ordinance shall be subject to the provisions in this Ordinance.
