Loma Linda has roughly 9,236 households, and the housing stock leans heavily toward that 1983 build window, consistent with the wider pattern across this part of the service area where most homes went up between 1958 and 1999, with a median year of 1981. Median household income here runs around $82,824, close to the $84,594 figure across the broader service area, which tells us most of these are owner-occupied single-family homes rather than rentals where upkeep gets deferred.
That combination - a 1983 median build year and steady household income - usually means the original garage door is long gone but the opener and track hardware are original or close to it. We find a lot of steel-rail horizontal track systems that were fine for the lighter doors of that era but now carry heavier insulated panels they weren't speced for, which shows up as a door that struggles or binds partway through its travel.
