No permit pertaining to any land or buildings shall be issued unless the Zoning Administrator has certified, after examination, that it complies with all provisions of this Ordinance and a Zoning Certificate has been issued and approved by the Zoning Administrator. In the O-R Office Research District and the ROC - Regional Office Center District, when the use is strictly office in nature and is so certified by an affidavit with occupancy information from the tenant or landlord, a Zoning Certificate is not required. Zoning Certificates are not required for the remodeling, renovation of, or expansion of any existing and approved use of a building when the existing occupant has an approved Zoning Certificate. The Zoning Administrator shall provide a monthly report of all approved Zoning Certificates and Affidavits of Office Use to the Village Board.

   A zoning certificate may be issued for a temporary use for a predetermined period of time in any Zoning District when the Zoning Administrator determines that the temporary use is compatible with the primary use of the property and in the public interest and when the temporary use is approved by the Board of Trustees.
