Electrical Panel Installation for Accessory Dwelling Units (ADUs)

Installing an electrical panel is a crucial part of setting up a safe and efficient electrical system for any Accessory Dwelling Unit (ADU). Whether you are converting a garage, building a detached backyard unit, or adding an in-law suite, the electrical panel is the heart of your ADU’s power distribution. It ensures that your appliances, lighting, heating, and other electrical needs are met without overloading the system.

Choosing the Right Electrical Panel for Your ADU

When installing an electrical panel for an ADU, it’s important to select one that meets your energy demands while also complying with local codes in Los Angeles and surrounding areas. A 100-amp panel is often sufficient for smaller ADUs, but larger units or those with energy-intensive appliances may require a 200-amp panel. Consulting a licensed electrician can help determine the appropriate size and configuration for your ADU.

Request a Meter Spot for Single-Family Residential ADUs

If you are installing a new electrical panel, you may need to Request a Meter Spot from your local utility company. A meter spot is an inspection and approval process conducted by the utility provider to determine the proper location for your electric meter. This ensures your panel and meter installation are compliant with utility regulations and safely accessible for meter readings and maintenance.

What is a Full Meter Spot?

A full meter spot is a site inspection conducted by the utility company to establish the exact location where your new meter will be placed. This is typically required when adding a new electrical service, such as for an ADU, or upgrading an existing panel. During the full meter spot inspection, the utility representative will assess your property and specify the exact spot where the meter can be safely installed.

Why is a Meter Spot Important for ADU Electrical Panel Installation?

  1. Compliance: Ensures your meter placement adheres to utility company standards and local codes.

  2. Accessibility: Confirms that the meter will be easily accessible for future readings, inspections, and maintenance.

  3. Safety: Verifies that the meter location is safe and minimizes the risk of electrical hazards.

  4. Avoid Delays: Securing approval for your meter spot early in the project can prevent costly delays during the panel installation process.

  • Load Calculation: Evaluate the total electrical demand based on your ADU’s appliances, lighting, HVAC systems, and other electrical needs.

  • Subpanel vs. Dedicated Panel: Depending on the ADU setup, you may either connect to the existing home panel via a subpanel or install a dedicated panel with a separate meter for the ADU.

  • Permits and Inspections: Always obtain the necessary permits and schedule inspections to ensure your electrical work meets city codes and passes utility company requirements.

  • Future-Proofing: Consider future energy needs, such as electric vehicle chargers, solar panel integration, or additional appliances when selecting your panel size and layout.

What Size Electrical Panel Do I Need for My ADU?

Most ADUs require either a 100-amp or 200-amp electrical panel. 100-amp panels are typically suitable for smaller units with basic appliances and lighting. 200-amp panels are better for larger ADUs or units with high-power appliances like air conditioners, electric water heaters, or EV chargers. A licensed electrician can calculate your electrical load to recommend the right size.

Do I Need a Separate Electrical Panel for My ADU?

It depends on your setup: Subpanel from the main house panel: If your main house panel has enough capacity, a subpanel can extend power to the ADU. Dedicated panel with a separate meter: If your ADU is being rented out or needs its own billing, a separate electrical panel and meter may be the best solution.

What Is a Meter Spot, and Why Do I Need It?

A meter spot is an inspection by the utility company to determine where your electric meter will be installed. It ensures safe and accessible placement for future readings and maintenance. It is often required when adding a new electrical panel or upgrading service. A Full Meter Spot is a more detailed inspection when installing a completely new meter for your ADU.

How Do I Request a Meter Spot for My ADU?

You’ll need to contact your local utility provider (like LADWP or Southern California Edison) to request a meter spot inspection. Your electrician can handle this process for you, ensuring the meter location is approved before panel installation begins.

How Long Does Electrical Panel Installation Take?

On average, electrical panel installation for an ADU can take: 1 to 2 days for a standard installation. Longer if you require a panel upgrade, meter spot approval, or permits.

What Permits Are Required for Electrical Panel Installation?

You’ll need an electrical permit from your local building department (e.g., City of Los Angeles). Inspections are required after installation to ensure the work meets code requirements.

Can I Upgrade My Existing Panel Instead of Adding a New One?

Yes, panel upgrades are common if your existing panel lacks capacity to support your ADU. For example, upgrading from 100 amps to 200 amps allows your main house and ADU to run safely on the same panel. A licensed electrician can evaluate your load capacity and recommend the best option.

What Happens If My Panel Isn’t Big Enough for My ADU?

If your panel is too small, you may experience: Frequent breaker trips. Overloaded circuits. Potential fire hazards. Upgrading the panel or installing a separate panel for the ADU is the safest solution.

How Much Does Electrical Panel Installation for an ADU Cost?

Costs can vary depending on: Panel size (100-amp vs. 200-amp). Meter spot requirements. Panel location complexity. On average, panel installations range from $1,500 to $4,000, but custom setups may vary.
