otherwise negotiated with the Building Official. Restoration shall be
compatible with the safe operation, maintenance, and inspection of the
City. All costs associated with the restoration of the site will be the
responsibility of the property owner.
d) Tranfer of ownership, Permits are not transferrable. If the portion of
