ADU Electrical Service with Roseville Electric Utility
How to get a service upgrade, a new or separate meter, or a relocated service from Roseville Electric Utility when you add an ADU, and what our electrical plans give you for that application.
Who Roseville Electric Utility serves
Municipal electric utility owned by the City of Roseville. Of the California places we cover, 1 is served mainly by Roseville Electric Utility, and together they issued 128 ADU building permits from 2021 through 2025.
How Roseville Electric Utility handles new and upgraded service
Roseville Electric Utility handles new service, service upgrades and meter changes through its New and Upgraded Electric Service process. This is separate from the building permit, so start it as soon as the electrical load calculation shows what the ADU needs. The steps Roseville Electric Utility describes:
- Submit the Electrical Panel Upgrade Application before applying for the building permit (email a photo of the existing and proposed panel location if possible).
- Roseville Electric reviews the application and contacts you by phone or email about next steps; if you are installing a new meter for an ADU, a representative contacts you to discuss options.
- Roseville Electric confirms approval and notifies the City Building Department; obtain the building permit.
- For new projects, building plans are routed to New Services Engineering, which reviews conductor/conduit size and quantity, switchgear access and location, the one-line diagram, and switchgear size; Roseville Electric invoices for its materials and labor, and payment is required before installation of Roseville Electric materials.
- Schedule an electrical disconnect with Roseville Electric Dispatch in advance of the panel replacement, and schedule the City building inspection for the same day.
- The property owner is responsible for conductors and conduits serving the panel (Roseville Electric does not install secondary conductors).
What Roseville Electric Utility asks for
- Electrical Panel Upgrade Application
- Photo of the existing panel location and proposed location (if possible)
- For new projects: building plans showing conductor and conduit size/quantity (transformer to switchgear), switchgear access/location, one-line diagram, and switchgear size
Our ADU electrical plans include the NEC Article 220 load calculation, panel schedule and single-line diagram, which cover the load and equipment information on this list. Site-plan and service-location details come from your architectural set.
A separate meter for the ADU
Roseville Electric's Electrical Panel Upgrade Application page says that if you are installing a new meter for an Accessory Dwelling Unit, a Roseville Electric representative will contact you to discuss options. No further ADU metering rule was found on the utility pages reviewed.
Whether a separate meter makes sense depends on the load calculation, the existing service size and the cost of the utility work. See when a separate service is required instead of a subpanel.
Service requirements
Meter location, clearances and service equipment must follow Roseville Electric Specifications for Metering (July 1, 2026); Construction Specifications. We show the meter and service equipment on the electrical plan so the location can be confirmed with Roseville Electric Utility early.
