Any application for development under this chapter, including an application for a building permit, special use permit, variance, or land development project, shall be deemed substantially complete when all required documents, including plans, along with required fees, are received by the official designated to receive such applications. Required documents shall include only those documents specified by this chapter, and/or rules adopted and published by the permitting authority prior to the filing of the application.

Any application for development under this chapter that is substantially complete prior to the enactment or amendment of this chapter shall be reviewed according to the regulations applicable in the Zoning Ordinance in force at the time the application was filed.

If such application is approved, the applicant must begin construction, or exercise the right granted in the application if no construction is involved, not more than one year after the date of the approval. The Zoning Board may, upon written request of the applicant, for good cause shown, extend the decision of the applicant for a period not to exceed six months. The request need not be advertised. All construction must be completed not more than two years after the date of approval, unless otherwise specifically set forth to the contrary in the approval. The granting of an extension also extends the two-year period in which the construction must be completed.
