Chino electrical questions

Could my Chino house have aluminum wiring?

Possibly, if built or rewired roughly 1965–1973[6]; 29% of Chino homes date from 1960–1979[1].

Which Chino ZIP codes are covered?

91710 and 91708[5] — San Bernardino County. Neighbouring suburbs with their own pages: Chino Hills (4.0 mi), Eastvale (4.9 mi), and Ontario (5.5 mi)[3].

A lot of Chino homes predate 1980 — what does that mean for wiring and panel work?

38% of Chino's housing units were built before 1980, 8.4% before 1960[1] — the 5th-highest share of the 15 Inland Empire suburbs we cover. Houses of that age may have smaller panels or original wiring; ask for a panel and grounding check before adding a big load such as an EV charger.

My Chino home is fairly new — could the wiring and panel still be under warranty?

Possibly: 21% of Chino's housing units were built in 2010 or later[1], the 3rd-highest share of the 15 Inland Empire suburbs we cover. Check your closing paperwork for warranties before paying for a repair.
