That is older than the Middlesex County median of 1974.¹ Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final.

That makes it a newer stock than Middlesex County as a whole (57% built before 1980).¹ Pre-1940 houses often have unlined chimneys, plaster walls and balloon framing, which change the scope of almost every trade.

Most housing units in Highland Park are not detached houses: 34% are in buildings of five or more units and only 32% are detached single-family homes.¹ With most units in multi-family buildings, condo and HOA approvals sit alongside the permit for interior work.
