North Haven's housing stock centers on 1964, a few years earlier than the median across the wider New Haven service area, which runs 1954 to 1986. That puts most of the neighborhood's garages squarely in the early-to-mid 1960s build wave, before a lot of the steel reinforced panel doors and extension-spring conversions that showed up later in the region's development. With 9,627 households here, there's a real concentration of these mid-century garages, enough that we see the same handful of door and hardware configurations over and over on calls from this area. Median household income here runs $126,807, higher than the broader service area figure, and that tends to show up in how people maintain these doors - more owners replacing worn sections before a full failure, fewer limping along on a cable that's already frayed. The climate band for this whole region is cold and severe, which matters more for 1960s-era doors than newer ones, since the original hardware wasn't built with today's insulation standards or spring cycle counts in mind. None of this is unique phrasing - it's just what the build year here tells us before we even see the door.
