I know of a house that will be coming up for sale, and it's something of a historic home - the architect was, if not famous, locally known and respected. The problem is I don't actually know the NAME of said architect. Besides this custom-built house, I know one other commercial building he designed. Are there old records I could go to, for either of these buildings, to find the architect?
Head down to the local building department for permit records. If they have drawings the architects name should be on them.
