We offer free quotes on every job, and our crew brings 25+ years of hands-on experience and full insurance to every project.
What ADU Electrical Wiring Involves
A dedicated sub-panel. Most ADUs need their own sub-panel to distribute power to kitchen, bath, and living area circuits independently from the main house.
Full interior wiring. Outlets, switches, and lighting circuits throughout the unit, plus dedicated circuits for major appliances like a range or water heater.
Capacity planning. A load calculation to confirm whether the existing main panel can support the added ADU circuits or whether a full panel upgrade is needed first.
Sun Day Electric evaluates your existing panel's available capacity during the free quote visit to confirm the right approach for your ADU project.
How We Approach an ADU Wiring Project
Assess existing capacity. We check the main panel's available amperage and run a load calculation to confirm it can support the new ADU circuits.
Install the sub-panel and wiring. We run the feeder circuit, install the sub-panel, and wire outlets, switches, lighting, and appliance circuits throughout the unit.
Permit and inspect. ADU electrical work requires permits and inspections under California code, and Sun Day Electric handles that paperwork and coordinates every inspection as part of the job.
If your main panel is already at capacity, we'll walk you through options like a panel upgrade before the ADU wiring begins.
