Woodlawn's housing stock centers on 1978, a good sixteen years earlier than the 1994 median you'll see across the wider Chapel Hill service area. That's not a small gap. A door and opener installed when a house went up in 1978 is a different animal from one installed in a house from the mid-90s, even if both have been "updated" once or twice since.
The service area as a whole runs mostly 1980s-90s construction across its ten named communities, and Woodlawn sits on the older edge of that spread. With 563 households here, it's a small pocket, but it's a consistent one - a lot of these garages were built to the same specs within a few years of each other, which means a lot of the same doors are aging out at the same time.
Median household income here is $74,712, a bit under the $79,512 median for the broader area. That matters less for what breaks and more for how homeowners tend to approach it: more people asking what can be repaired before they ask what a full replacement costs.
