ADU electrical projects involve more than running a few circuits. Sub-panel sizing, dedicated metering, permit coordination, and load calculations all need to be handled correctly. King Electric and Solar works with homeowners across Auburn, Roseville, Rocklin, and surrounding Placer County communities to get ADU electrical installations done to code and ready for inspection.
Every ADU has different electrical demands. Here is what we typically handle on these projects.
Sub-panel installation sized to your ADU's load requirements
Service upgrade to the main panel when needed
Dedicated circuits for kitchen, bath, and HVAC equipment
Outlet, switch, and lighting rough-in and trim-out
Smoke and carbon monoxide detector placement per code
EV charger circuit added during ADU build when requested
Final inspection walk-through and punch list corrections

King Electric was excellent. The quality of work, customer service, and timeliness can't be beat. Blakely was excellent explaining the process and providing the needed information for our new 50 amp connection.

ADU electrical work follows a clear sequence tied to the construction schedule. We coordinate each phase so inspections pass and your project stays on track.
We visit the property, review your ADU plans, and calculate the electrical load to determine whether the existing service can support the addition or needs an upgrade.
We handle permit documentation for the electrical scope and schedule rough-in work to align with your general contractor's framing and insulation timeline.
Conduit, wiring, sub-panel, and all rough electrical work get installed before drywall. We coordinate the rough inspection so you do not lose schedule days waiting.
After drywall and paint, we return to install outlets, switches, fixtures, breakers, and any specialty circuits like EV chargers or dedicated appliance lines.
We complete the final inspection with the authority having jurisdiction, address any corrections on the spot when possible, and walk you through the completed electrical system.
Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.
Q1
Most ADUs do require a dedicated sub-panel to keep the unit's circuits separate from the main home. It also simplifies future metering if the unit is rented. We confirm what is required based on your local jurisdiction and load calculations during the initial visit.
Q2
It depends on the current panel capacity and what the ADU will contain. A unit with electric cooking, a heat pump, and an EV charger adds meaningful load. We assess your existing service and let you know upfront whether an upgrade is necessary.
Q3
Yes. We handle permit submittal for the electrical scope of the project. Permit requirements vary between Auburn, Roseville, Rocklin, and other Placer County jurisdictions, and we are familiar with the process in each area we serve.
Q4
Separate metering for an ADU involves coordination with PG&E and the local jurisdiction. We can install the electrical infrastructure to support a second meter and guide you through the utility application process.
Q5
The electrical scope itself is not the longest part of an ADU project, but scheduling inspections adds time. Rough-in typically takes one to two days. Trim-out is usually a single day. Total elapsed time depends on inspection scheduling and the rest of the construction timeline.
Q6
Yes. King Electric and Solar installs solar systems and EV charger circuits, and it often makes sense to plan for those during the ADU electrical rough-in rather than adding them later at greater cost.
Q7
We serve Auburn, Roseville, Rocklin, Folsom, Lincoln, Grass Valley, Nevada City, and El Dorado Hills. If your project is in Placer County or the surrounding foothills, reach out and we can confirm coverage.
Q8
Having your ADU plans or a basic description of the unit size and intended use is helpful. We also want to know whether construction is already underway or in the planning stage. That lets us give you a realistic picture of what the electrical scope will involve.
