Northville's housing stock centers on a median build year of 1970, a few years newer than the broader Novi service area, where homes typically date back to 1965. With roughly 2,574 households here, this is a smaller, tighter pocket than the 188,906-household area we cover out of Novi - and the homes in it tend to sit on the newer end of what we see across the territory.
That 1970 median matters because it puts most Northville garage doors just past the point where builders switched from the oldest torsion setups to hardware that's a little easier to source parts for today. It's not a clean cutoff - plenty of houses here were built well before or after that median - but it shifts the odds in your favor compared to some of the older pockets closer to Novi's center.
Income here also runs well above the area average: $143,875 median household income in Northville against $90,077 across the full Novi service area. That doesn't change how a torsion spring fails, but it does mean we see more owners asking for a full opener upgrade instead of a patch job when a door starts acting up, since the budget for it is usually there.
