ADU Electrical Work in Orange County,
What You Need to Know
Accessory Dwelling Units — ADUs — are booming across Orange County. Whether you're building a backyard cottage, converting a garage, or adding a second unit above your garage, proper electrical work is one of the most critical parts of the project. Here's what every Orange County homeowner needs to know.
What Electrical Work Does an ADU Require?
Every ADU requires dedicated electrical service. This typically includes a sub panel for the ADU, new circuits for all outlets, lighting, appliances, and HVAC, a dedicated circuit for the kitchen and bathroom, exterior weatherproof outlets, smoke and carbon monoxide detectors wired to code, and EV charging capability if required by your city.
Do I Need to Upgrade My Main Panel for an ADU?
In most cases yes. Adding an ADU significantly increases your home's electrical demand. If your main panel is already at or near capacity, a panel upgrade is required before a sub panel can be installed for the ADU. During our free estimate we assess your main panel and give you an honest recommendation.
