South Lyon's housing stock runs newer than most of what we see across the rest of our coverage area. The broader service territory has a median build year of 1965, with homes going back to 1938 in some pockets. South Lyon itself centers closer to 1991 - a solid generation newer. That gap matters because a door installed in a house built in 1991 is a different animal than one built in 1965: different track widths, different headroom assumptions, different spring systems as standard.
With roughly 5,033 households in the area and a median income of $83,822 - a bit below the wider service area's $90,077 - South Lyon reads as a working, mid-income community of houses that were mostly built new rather than renovated from older farmhouses or postwar bungalows. That has a direct effect on what we find when we open a service call here: fewer one-off custom door sizes, more standard-width double and single doors built to code specs that were current in the late 1980s and early 1990s.
We don't have a block-by-block count of which subdivisions came in which decade, so we're speaking to the area median, not every street. If your house is one of the older outliers, the hardware conversation below may not match your door exactly.
