The largest single share, 40%, dates from 1980-1999. That makes it an older stock than DuPage County as a whole (54% built before 1980).¹ On houses from the 1980s and 1990s, polybutylene supply lines, builder-grade windows and first-generation openers are the usual items a contractor confirms before quoting.
