Home Rewiring in San Jose, CA
San Jose has thousands of Eichler homes, and rewiring or adding circuits in them is a specialty job. Post-and-beam construction, exposed ceiling beams, glass walls and radiant heating in the slab leave few hidden cavities for wiring, so electricians often route new circuits through the roof, use surface-mounted raceway or open walls selectively.

What's different about home rewiring in San Jose
Older Willow Glen and downtown homes may have knob-and-tube instead. Either way, the electrician should explain the routing plan before starting. Permits come from Planning, Building and Code Enforcement. A documented rewire also helps at resale, when buyers ask about older wiring.
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.
