Spring Lake sits about 2 miles from Grand Haven, close enough that the two areas share a building era in broad strokes but not in the particulars. With roughly 1,272 households, this is a smaller, tighter area than the service region as a whole, and the housing reflects a narrower build window centered on the late 1950s rather than the wider 1945-1988 spread you'll find elsewhere.
Median household income here runs $75,000, noticeably above the $62,575 median across the full service area. That shows up less in the garages themselves and more in what owners choose to do about them - we see more full opener replacements and fewer patched-together repairs than in some of the older, lower-income pockets nearby. It doesn't change the physics of a 1958 door, but it does change what people decide is worth fixing versus replacing.
