Nothing in this chapter prevents the ordinary maintenance or repair of any exterior feature in or on an historic property that does not involve a change in design, material, or outer appearance, nor prevents the construction, reconstruction, alteration, restoration, demolition, or removal of any such feature if a building inspector or similar official certifies to the Historic Preservation Commission that such action is required for the public safety because of an unsafe or dangerous condition.
