That is older than the Salem County median of 1962.¹ 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. The stock is old by national standards: 90% of Salem's housing units were built before 1980 (U.S. 50%), and only 3% since 2010. The largest single share, 46%, dates from before 1940. That makes it a newer stock than Salem County as a whole (75% built before 1980).¹ Pre-1940 houses often have unlined chimneys, plaster walls and balloon framing, which change the scope of almost every trade.
