Across the Sioux Falls service area, homes were built between 1938 and 2006, with the median build year landing around 1983. Most of the houses in the 14 communities we cover - Harrisburg, Tea, Brandon, Hartford, Valley Springs, Worthing, Baltic, Lennox, Garretson, Chancellor, Canton, Humboldt, Dell Rapids, and Colton - fall into that 1980s-to-90s wave of construction, rather than at either end of the range.
That matters because garage doors and openers from that era share a common profile: steel sectional doors on extension or torsion spring setups, openers that have usually been swapped out once or twice by now, and track hardware that was built to a lighter spec than what goes in today. A door original to a 1983-built house is pushing 40 years old if nobody's touched it, and most of these towns have a lot of houses sitting right at that mark.
With 16,761 households across the area and 10,546 of them owner-occupied, and median household income at $96,228, this isn't a market where people are stretching to keep an old door running past its useful life - most owners replace rather than patch once a door's hardware starts failing in multiple places at once. We order the towns below by distance from Sioux Falls, not by age, because the housing-era data we have covers the area as a whole rather than breaking out each town separately.
