Each request for the demolition of any building over fifty (50) years old which is not a Historic Site or Historic Neighborhood Combining District shall be accompanied by one clear photograph, of the front of the building, submitted by the applicant. The age of the structure shall be determined or verified through public records or from an inspection. A demolition permit shall not be issued for such building until the Planning Director has had a period not to exceed thirty (30) days to investigate and document the historic value of the building, and attempt to arrange the preservation of the building. After the expiration of the thirty (30) day period, the permit may be issued in accordance with the building department procedures. The thirty (30) day period may be waived by the Planning Director where there is imminent danger to life, limb or health of the public which requires immediate demolition. (Prior code § 4-14-1)
