That is in line with the Los Angeles County median of 1965.¹ 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: 68% of Willowbrook's housing units were built before 1980 (U.S. 50%), and only 9% since 2010. The largest single share, 29%, dates from 1940-1959. That makes it much the same age as Los Angeles County as a whole (70% built before 1980).¹ On houses from the 1940s and 1950s, contractors routinely check for original cast-iron drains, two-wire electrical and undersized panels before pricing a remodel.
