Note: Prior history: Prior Code § 9-113.1 and Ord. CS 96.
It is the intent of these district regulations to support and enhance the character of historical areas within the county. These district regulations also recognize historical structures as a finite resource which is a product of another time and worthy of special consideration. When new additions, alterations, or rehabilitation projects are proposed to existing structures and are approved by the historical site subcommittee of the county planning commission or planning staff, these district regulations shall enable the building official to grant exemptions from building code requirements when in his or her opinion such maintenance of the historical character of such buildings or structures and the granting of the exemptions will not create or allow any condition which is immediately hazardous to life or property. The existing unique character of these areas is considered a scenic and economic asset and has significant value to the general welfare. The review provided for by this chapter is intended to ensure that any development in the subject areas will not be unsightly, undesirable, or obnoxious to the extent that such development will impair the quality of the area. The following regulations shall apply in HS districts and shall be subject to the provisions of Chapter 21.08.
