No. The Historic Preservation Ordinance chapter 17.32, does not require you to restore your building or to make improvements when you don’t have any plans to do so. Further, making a newer building look old is not required – in fact, it is contrary to the guidelines. If you decide to improve your property or carry out repairs, the ordinance requires the project to be consistent with the overall architectural character of the building and the district as a whole.
