Highland Park's housing stock centers on a median build year of 1973, which puts it well ahead of the broader service area's 1999 median. That two-decade gap matters more than it sounds like it should. A house built in 1973 was framed and trimmed out before steel garage doors with foam insulation were standard, and before torsion springs with modern winding cones became the default hardware. A lot of these homes still carry their second or third door, but the header, the track spacing, and sometimes the opener bracket were sized for what went up originally. With 3,249 households in the area and a median income of $250,001, we also see more owners who've already put money into upgraded doors and openers than you'd find in an older working-class subdivision - but the bones of the house underneath are still 1970s bones, and that shapes what fits and what doesn't.
