As housing needs shift and property values rise, Accessory Dwelling Units (ADUs) have become an increasingly popular solution for Sacramento homeowners. Whether used as a rental property, guest suite, or independent living space for family members, ADUs offer flexibility and long-term value. But before you start construction, it is essential to speak with an electrician to understand one of the most critical aspects of any ADU project, the electrical system.
At Rios & Burke Electric, we specialize as ADU electricians in Sacramento and have worked with countless homeowners, general contractors, and developers to design and install electrical systems that are safe, code-compliant, and ready for modern living. If you are planning an ADU or already in the process, here is what you need to know.
Why Electricians for an ADU is Crucial 
Electrical planning is one of the first and most important steps in any ADU project. Unlike basic remodels, an ADU often functions as a completely independent living unit. This means the electrical setup must support everything from lighting and appliances to HVAC systems, Wi-Fi, and potentially EV charging.
Poor planning can lead to overloaded circuits, inconvenient outlet placement, or the need for expensive retrofitting after construction. Working with experienced ADU electricians in Sacramento ensures your system is designed correctly from the start and avoids costly issues down the road.
Key Considerations for ADU Electrical Systems
1. Determining the Right Electrical Load
One of the first steps in designing an ADU’s electrical system is determining the required load capacity. This will depend on:
-
The total square footage of the ADU
-
Number and type of appliances (electric stove, washer/dryer, HVAC)
-
Lighting systems and controls
-
Hot water systems (tank or tankless electric units)
-
Any smart home features or additional needs like an EV charger
A licensed electrician will perform a load calculation to determine whether your current panel can support the ADU or if a panel upgrade or new subpanel is necessary. This step ensures the system will be safe, reliable, and capable of handling your future power needs.
2. Deciding on a Subpanel vs. Separate Meter
In most ADU setups, homeowners choose between connecting the unit to the main house’s panel or installing a separate electrical meter. Each option has pros and cons:
-
Subpanel Setup: Easier and more cost-effective, especially if you are not planning to rent the unit separately. The ADU’s electricity usage is bundled with the main home’s utility bill.
-
Separate Meter: Offers full independence, which is ideal for rentals. Tenants receive their own bill and utility responsibility is clearly separated. This option is more expensive and requires coordination with your local utility provider.
Rios & Burke Electric can guide you through the decision based on your goals, property layout, and budget.
3. Meeting Local Code Requirements
The City of Sacramento has specific code requirements for ADUs, including those related to electrical safety. These include:
-
GFCI-protected outlets in kitchens, bathrooms, and exterior areas
-
ARC-fault breakers in living and sleeping spaces
-
Proper outlet spacing and height based on California Residential Code
-
Adequate exterior lighting for entrances and walkways
-
Smoke and carbon monoxide detectors powered by the electrical system
Working with experienced ADU electricians in Sacramento ensures your build meets all required codes and passes inspection the first time.
4. Planning for Modern Living
Today’s homeowners and tenants expect more from their living spaces. Your ADU should not feel like a downgrade from a main residence. Consider incorporating modern electrical features like:
-
Dimmers and smart lighting controls
-
Ceiling fans in main rooms and bedrooms
-
USB outlets in living and bedroom areas
-
Wi-Fi-enabled thermostats
-
Wired ethernet drops for strong internet connectivity
-
EV charger-ready circuits (especially for detached garage conversions)
These details add convenience and appeal to future renters or family members who will use the space.
5. Coordination with Other Contractors
ADU projects involve multiple trades, from framers and plumbers to HVAC techs and finish carpenters. ADU electricians need to carefully coordinate with these professionals, especially when it comes to conduit placement, recessed lighting, appliance hookups, and wall space availability.
Rios & Burke Electric works closely with general contractors and project managers to ensure seamless integration with other parts of your ADU construction process. We prioritize communication and efficiency to avoid delays or costly rework.
