Subpanel Installation in Ukiah, CA

Extending Capacity to Where You Need It

Subpanels for detached structures, additions and workshops fed from your main panel.

A subpanel is fed by a dedicated feeder circuit from the main panel and gives a garage, ADU, or workshop its own set of breakers close to where the load actually is, which is common on rural Mendocino County parcels with detached structures spread across the property. We size the feeder and subpanel based on what will actually be installed there, whether that's a few outlets and lights or a shop full of 240V tools, and calculate voltage drop for longer underground or overhead feeder runs.

Subpanels feeding detached structures need their own grounding electrode system per NEC 250, separate from the main panel's ground, which is a step we see missed in older DIY installations we're called to correct. This work requires a permit and inspection just like a main panel, and if the subpanel feeds a habitable space like an ADU, additional code requirements around AFCI and GFCI protection apply.

We'll tell you upfront whether your main panel has enough spare capacity to feed a subpanel or whether an upgrade needs to happen first.

Residential Electricians Who Know Ukiah Homes

We work here every day, so we know what's behind the walls before we open them.

Much of Ukiah, Calpella, and Hopland was built long before modern loads, heat pumps, induction ranges, shop tools, EV chargers. We see the same failure patterns weekly: undersized 100-amp services, aluminum branch circuits, ungrounded two-prong outlets, and panels no longer supported by breakers you can buy.

We know which county desk handles your permit and which inspector will be at the meter.
