Homes and wiring in San Jose

San Jose is mostly post-war tract housing from the 1950s through the 1970s, including many Eichler homes, with older 1920s and 1930s homes in Willow Glen and near downtown. EV adoption in Silicon Valley is among the highest in the country, and electrification drives most panel work.

Tract homes often have 100 amp services that cannot carry an EV charger, a heat pump and an induction range together. Eichlers, with post-and-beam construction, exposed ceilings and radiant floor heat, leave little hidden space to run new wiring.

Weather, seasons and the utility

San Jose has a mild climate, but inland summer heat waves are becoming more frequent, and many homes built without air conditioning are adding heat pumps. Earthquakes are the main natural hazard, with active faults on both sides of the valley. PG&E owns the wires and meters, while most residents buy their power through San José Clean Energy, the city's community choice program. That means service upgrades, panel changes and solar interconnection are coordinated with PG&E, whose scheduling can take weeks or longer, so plan electrification projects well ahead.

Local issues electricians see

  • Panel and service upgrades for EVs and electrification
  • Wiring challenges in Eichler post-and-beam homes
  • Older wiring in pre-1940 Willow Glen and downtown homes
