For guest houses and accessory dwelling units (ADUs) in California, electrical work must adhere to the California Electrical Code (Title 24, Part 3). Compliance requires obtaining permits and passing inspections through local building departments, such as the Los Angeles Department of Building and Safety (LADBS).
Key requirements include:
- Dedicated Disconnecting Means: Detached guest houses must have their own disconnecting means and a subpanel fed from the main service.
- Electrical Panel Capacity: A professional load calculation is necessary to determine if the existing service can handle the added load. Many projects require an Electrical Panel Upgrade or Sub Panel Installation to support new circuits for lighting, appliances, and HVAC.
- Mandatory Circuit Protection: GFCI protection is required for receptacles in kitchens, bathrooms, outdoor areas, and garages. AFCI protection is mandatory for circuits in bedrooms and living areas.
- Safety Alarms: Hardwired, interconnected smoke and carbon monoxide alarms with battery backups must be installed in living and sleeping areas.
