Streamwood's homes center on a median build year of 1981, which puts this area a few years past the 1976 median for the wider service territory we cover out of Wheaton. Across the 542,515 households in that broader area, the stock runs mostly 1960s-70s, so Streamwood's 1981 median puts it toward the newer end of that range rather than the older end.
The area holds about 13,041 households, with a median income of $101,049 - a bit above the $97,861 median for the full service area. We run this route from Wheaton, 12 miles out, on the way past or near Bartlett (8 miles), Wood Dale (10 miles), and Bensenville (11 miles), all part of the same general stretch we cover.
A 1981 build year matters because that's the era when steel roll-formed panels were replacing wood in most new construction, and torsion spring setups on double doors were becoming standard rather than an upgrade. Homes built right around then often still have their original hardware, just worn.
