For accessory dwelling unit (ADU) projects in Los Angeles, the electrical requirements are governed by the California Electrical Code (CEC), Title 24, Part 3. While the specific utility meter configuration can depend on your project goals, a detached ADU must have its own disconnecting means and typically requires a subpanel fed from the main service.
Key electrical requirements for a code-compliant ADU include:
- Electrical Panel Upgrades: Because many older homes in Los Angeles and Marina del Rey lack the capacity for the added load of an ADU, a panel upgrade or Sub Panel Installation is often necessary.
- Load Calculations: We perform detailed calculations per NEC Article 220 to account for lighting, appliances, and high-draw items like EV charging or electric heating.
- Safety Protections: Mandatory GFCI protection is required for kitchens, bathrooms, and outdoor receptacles, while AFCI protection must be installed for all living and sleeping area circuits.
- Interconnected Alarms: California building codes require hardwired, interconnected smoke and carbon monoxide alarms throughout the unit.
Before work begins, a permit must be obtained through the Los Angeles Department of Building and Safety (LADBS) or the County Department of Public Works. We recommend scheduling a professional on-site evaluation to determine your specific panel capacity and available utility rebates that may help offset the cost of your installation.
