Heritage districts and old cores
Cambridge has three Heritage Conservation Districts: Blair, Dickson Hill in Old West Galt, and the Main Street area. Inside them, changes to the outside of a house need a heritage permit on top of the building permit. Interior work is not restricted, but anything visible from the street, including windows and porches, is. Outside the districts, Galt, Preston and Hespeler still have plenty of pre-1920 brick and stone homes with plaster walls, uneven floors and small rooms.
