A revised set of design guidelines for Gainesville’s historic districts separates residential-style buildings used as homes from those occupied by businesses. “Pretty much, the major change is that it was reorganized to make it more user-friendly,” said Jessica Tullar, Gainesville’s special projects manager. “In terms of text, really the only difference is that we added guidelines for commercial-style buildings such as the Big Bear Cafe, which is a local, individual landmark.”
