Streamwood has 13,041 households, with a median household income of $101,049 - a step below the wider service area's $111,898, which tracks with the kind of mid-size, built-out suburb this is rather than the newer-money edges of the territory. The housing here was built smack in the middle of the broader area's 1955-2009 range, at a median year of 1981, which lines up with the area-wide pattern of 1980s-90s construction across the 81 named communities we cover. That matters more than it sounds like it should: a town built in one steady wave has doors, openers, and tracks that fail in predictable batches, not a random mix of eras. It's part of why a cold-climate, 80s-era suburb like this one calls about the same handful of problems over and over, rather than a grab bag of everything that's ever gone wrong with a garage door.
