Region-wide 1984 baseline
Across the wider Florence footprint, the median home was built in 1984 - lots of older torsion setups, repainted steel doors, openers that have outlived three remotes. Union skews much newer, with a median build year closer to 2005. That matters for maintenance because newer doors use steel-and-composite panels, lighter springs rated for less cycle wear over time, and circuit-board openers instead of the old chain-drive relay units.
