No, the WHS plaque does not affect the legal status of your house or building in any way. The only time historical concerns affect the legal status of a building to the city of Waltham is when a demolition permit is requested. In this case, all buildings 75 years of age or older are automatically evaluated by the Waltham Historical Commission for historical significance. Also, in Waltham, the city has no control over what you do with the appearance of your house short of demolition. No one can tell you what color to paint your house, what replacement windows to choose, or other such modifications. However, if you take pride in the historical appearance of your house, we encourage you to consult such programs as Historic New England's Historic Homeowners Program on ways to enhance its historical appeal.
