ADU Electrical Wiring in San Ramon, Danville, Walnut Creek & the East Bay
Crow Canyon Electric provides electrical work for accessory dwelling units (ADUs) in San Ramon, Danville, Blackhawk, Walnut Creek, Berkeley, Oakland, Alameda, Livermore, Pleasanton and Fremont. We plan the power, run the feeder from your main panel, install the sub panel and wire the unit, coordinated with your builder and inspector.
ADU Electrical done properly, start to finish
An ADU is a small home of its own, and it needs the same electrical basics: a panel, safe circuits for the kitchen and bath, lighting, outlets and often an EV charger or solar connection. The question that decides the design is how the power reaches it, and whether your existing service can carry another household’s load.
We start with that question. We check your main panel, plan the feeder and sub panel, and lay out circuits for the unit. Because we also do panel upgrades, EV chargers and lighting, one electrician can cover the whole project. City and utility requirements vary by address, so we confirm them early rather than at inspection.

Typically a feeder from the main panel, a sub panel, circuits for the kitchen, bath and living areas, lighting, detectors and often an EV charger. The exact scope depends on the design and your city.
Sometimes. We calculate the load first. If the panel is short, a main panel upgrade is the next step.
Yes. We schedule rough-in and finish work around the builder’s timeline and the inspections.
We serve San Ramon, Danville, Blackhawk, Walnut Creek, Berkeley, Oakland, Alameda, Livermore, Pleasanton and Fremont, within about 25 miles of San Lorenzo.
It depends on the unit’s size, the feeder distance, whether the main panel needs an upgrade, and what the unit includes, such as a kitchen, heating and cooling, or an EV charger. We quote after reviewing your plans. Call (510) 650-9113 for a quote.
It depends on your utility, your city and your plans. Many ADUs are fed from the main house through a sub panel, and some get their own meter. We help you confirm the requirement early.
If the combined load of the house and the ADU is more than the existing service can carry, yes. We calculate the load first so you know before construction.
Often yes with the right planning. Feeders, panels and utility rules vary, so it is best to plan solar and charging before the walls are built.
