embers are extinguished (or other damaging occurrence has ended) and (ii) either
demolished (in accordance with Chapter 18 of this Code) or rebuilt in conformity with
applicable technical codes as though it were a new building. Normal permits
(including certificate of occupancy) are required. Work to demolish or rebuild must
begin within 60 days following the date the occurrence ends and must be completed
within a reasonable time, but not longer than the time allowed by the applicable
permit(s). To determine the "market value" of a pre-existing building, the most
