ADU Electrical Requirements – Full Turnkey Installation by LA Pro Electrical

When planning an Accessory Dwelling Unit (ADU), understanding and meeting the electrical requirements is not optional—it’s essential. From load calculations to outlet spacing, code compliance ensures your ADU is safe, functional, and legally approved. At LA Pro Electrical, we simplify the entire process with a turnkey solution that handles every aspect of your ADU’s electrical setup—from panel to final inspection.

Unlike companies that outsource or resell your job to a third party, we build it all ourselves, in-house. No extra markups. No delays. Just expert-level work completed by licensed professionals from day one.

What Are ADU Electrical Requirements?

ADU electrical requirements refer to the local and state codes that govern how the electrical system must be designed and installed in a new or converted ADU. These include:

  • Proper panel sizing and service entrance

  • Load calculations based on appliance usage

  • Required number and placement of outlets and lighting

  • Grounding, bonding, and GFCI/AFCI protection

  • Smoke and carbon monoxide detector wiring

  • Compliance with California Electrical Code and Title 24

  • Approval from city inspectors and utility providers like LADWP

Every city has specific electrical permitting standards, and LA Pro Electrical has passed every single inspection we’ve been a part of in Los Angeles.

Our Process Covers Every Requirement

We’ve designed our process to make sure every detail of your project meets ADU electrical code requirements in Southern California:

⚡ Load Calculation & Panel Sizing

We calculate your total electrical demand and determine if a new main panel or subpanel is needed for safe, efficient power distribution.

⚡ Outlet, Lighting & Circuit Layout

We install up to 46 outlets and 50 lights per 1,000 sq. ft. as part of our base package—meeting all spacing, switch, and safety codes.

⚡ Dedicated Appliance Circuits

Stoves, refrigerators, laundry, and tankless water heaters all require dedicated circuits—we handle that in-house and include it in your plan.

⚡ Exterior, Smart, and Energy-Efficient Options

From dusk-to-dawn outdoor lights to smart switches and dimmers, we tailor your system to meet both lifestyle and energy code standards.

⚡ Permits and Inspection Readiness

While the general contractor typically pulls the permit, we guarantee our electrical work passes city inspection, every time.
