Census and NOAA figures for the city of San Jose in Santa Clara County, not the metro, with a source for each.
The median home in the city of San Jose was built in 1976, older than the U.S. median of 1980 and about the same as the California median of 1976.1 Somewhat more of San Jose's housing predates 1980 than the national share: 60% against 50%, with 9% built since 2010.1 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. Owner-occupied homes in San Jose are older than rentals: a median build year of 1973 against 1979.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.
San Jose has a mixed housing stock: 51% detached houses, 11% attached or townhouse units and 28% in buildings of five or more units.1 56% of occupied homes in San Jose are owner-occupied (56% statewide).1 The median owner-occupied home in San Jose is valued at $1,233,200 (ACS), above the California median of $734,700.1 Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.
Freezing nights are rare: the nearest NOAA station (San Jose) averages 3.2 nights a year at or below 32°F.2,3 With few freezing nights, water and sun rather than ice are what exterior details are built against. Summer heat is moderate: about 16 days a year reach 90°F.2,3 Annual precipitation is low, about 13 inches.2,3 Low rainfall shifts the wear to UV and heat, which age finishes and sealants.
Heating dominates the year: about 2,184 heating degree days against 624 cooling degree days (base 65°F).2,3 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope. San Jose is about 23 miles from the ocean or Gulf coast in a straight line.4,5 Proximity to salt air makes fastener grade and corrosion protection part of every exterior quote.
