Golden Valley's housing stock centers on 1966, which puts it a decade or so ahead of the wider service area's 1977 median. That matters because a house built in the mid-60s was framed before the common two-car, double-wide garage opening became standard in a lot of the newer subdivisions out this way. A lot of Golden Valley garages are single bays or narrow doubles, built to fit a shorter driveway and a smaller footprint than what went up in the 1970s and 80s elsewhere in the area.
With 9,671 households in Golden Valley, you've got a dense pocket of similarly-aged homes, which means similarly-aged garage doors and similarly-aged failures. When one torsion spring on a 1966-vintage door goes, the one next to it on the same house is usually not far behind, and the house two doors down with the same build year is often in the same boat. We see this pattern repeat across blocks that went up in the same construction wave.
Median household income here runs $114,435, a bit above the wider area's $109,722, and we see that reflected in more owners opting for full replacement with insulated steel over patching a 60-year-old wood or single-layer door once the repair bills start adding up.
