Across the wider service area, homes went up mostly in the 1980s and 90s, with a broad range from 1938 to 2015 spread over 31 named areas. Great Falls itself carries a slightly later median - 1985 - and about 4,970 households, small next to the roughly 147,261 households and 52,770 owner-occupied houses across the whole territory we cover. Median household income here, at roughly $250,001, is well above the broader area figure of $154,734, and that gap tends to track with property size and door count rather than door age - a lot of these are two- and three-car setups, not single bays. What that means for door hardware is straightforward: more doors per house built in the same fifteen-year window, aging out roughly together.
