Accessory Dwelling Units (ADUs) are a great way to expand living space, create rental opportunities, or add value to a property. However, ensuring the ADU is wired correctly and meets Los Angeles electrical codes is crucial for safety, efficiency, and compliance. At LAProElectrical, we have completed over 300 ADU electrical projects, offering turnkey solutions from planning to final inspection. This guide covers everything about ADU electrical installation, including permitting laws, wiring requirements, and cost considerations.
Planning Your ADU Electrical Installation
Before starting an ADU electrical installation, careful planning is essential. Key steps include:
Determining Electrical Load – Consider appliances, HVAC systems, lighting, and EV chargers when calculating power needs.
Panel Assessment – Homes with a 100-amp panel may require an upgrade to a 200-amp panel or a subpanel installation to support additional load.
Placement of Wiring & Outlets – Outlets should be spaced every 6 feet, with dedicated circuits in the kitchen and bathroom for high-powered appliances.
Smart Home & Energy Efficiency – Smart home integration, solar power, and LED lighting can enhance efficiency.
Do You Need an Electrical Panel Upgrade for Your ADU?
The existing electrical panel capacity determines whether an upgrade is necessary. Here’s when an upgrade is required:
100-amp panel – Likely insufficient for an ADU; a 200-amp upgrade is recommended.
200-amp panel – May be sufficient unless multiple high-powered appliances or an EV charger are included.
Subpanel Installation – Best for detached ADUs, allowing independent circuit control.
A panel upgrade or subpanel installation ensures the ADU receives sufficient power and prevents overloaded circuits.
Permits & Electrical Code Compliance in Los Angeles
In Los Angeles, CA, ADU electrical installations must comply with Title 24 regulations and local electrical codes. Key requirements include:
Permit Requirements – Permits are required for panel upgrades, new wiring, dedicated circuits, and subpanel installations.
Inspection Process – A city inspector will verify compliance with electrical codes before final approval.
Title 24 Compliance – Energy efficiency requirements include LED lighting, circuit configurations, and GFCI protection in wet areas.
At LAProElectrical, we handle the entire permitting process, ensuring the project passes inspection on the first attempt.
DIY ADU Electrical Installation: Risks & Challenges
Some homeowners attempt DIY ADU wiring, but unexpected problems often arise, such as:
Code Violations – Improper wiring can fail inspection, leading to costly corrections.
Overloaded Circuits – Miscalculations in electrical load may cause breaker trips and power failures.
Safety Hazards – Incorrectly installed outlets, faulty wiring, or missing GFCI protection increase risks of fire and electrical shock.
Hiring a licensed ADU electrician ensures safe, reliable, and code-compliant electrical work.
