West Lake Hills sits in a moderate heat band, not an extreme one, so the failures here aren't heat-cycle failures the way they might be in a harsher climate zone. The wear is plain age acting on hardware that's had three and a half decades of cycles. At $211,471, median household income in West Lake Hills runs well above the $121,750 figure for the broader Austin service area, and that tends to mean buildings get looked after rather than left to fail outright - repairs get called in early, not after a full breakdown. But maintained doesn't mean replaced. A spring that's been kept lubricated and adjusted still has a fixed number of cycles in it, and once that count runs out, upkeep doesn't buy more time. The other factor is scale: a commercial stock this small, tied to a housing base of only 1,208 households, means there isn't a dense cluster of similar buildings to draw a pattern from the way you'd get in a bigger commercial district. Each door here gets diagnosed on its own history, not on what the building next door did.
