The Building and Zoning Inspector may issue, and shall issue upon the request of any owner, a certificate for any structure, use of land and/or structure, or lot that certifies that the structure, use of the land and/or structure, or lot is a valid nonconformity. The certificate shall specify the reason why the structure, use or lot is a nonconformity, including a description of the extent and kind of use made of the property in question, the portion of the structure or land used for the nonconforming use, and the extent that dimensional requirements are nonconforming. The purpose of this section is to protect the owners of lands or structures that are or become nonconforming. The fee for such a certificate shall be the same as a minor zoning certificate.
