In the event that the Commission finds that, notwithstanding the necessity for preventing demolition by neglect, the action provided for in Section 29-114(c) would impose a substantial undue hardship on the owner(s) of record of the subject property, the Commission shall seek alternative methods to preserve the historic resource. If none are confirmed within a reasonable time, the Director shall not proceed in accordance with Section 29-114(b), but shall issue the permit. However, the Historic Preservation Commission shall be permitted to make measured drawings and photographs, or on-site documentation by some other method within a mutually agreeable period of time.
