A new electrical panel installation is required for any new construction, detached addition, accessory dwelling unit, or major renovation that involves establishing new electrical service. Unlike a panel upgrade — which replaces an existing panel — a panel installation provides service to a structure that does not yet have it. This includes ADUs with separate utility meters, detached garages being converted to living space, workshops requiring dedicated service, and new construction requiring a complete service entrance. Our licensed electricians handle the full scope: load calculation, equipment selection, permit filing, utility coordination, and inspection.
Electrical Panel Installation — Everything You Need to Know
From sizing and permits to what the install day looks like — here’s what homeowners need to know about electrical panel installation before requesting service.
What Panel Installation Involves
A new panel installation begins with a load calculation to determine the correct service size for the structure’s intended use. We select and install the main panel, service entrance conductors, meter base, and weatherhead appropriate for the utility’s requirements. For ADUs and additions connected to an existing service, we assess whether the existing capacity supports the added load or whether the main panel requires an upgrade. All work is coordinated with the utility for the service connection, and permits are filed with the relevant building authority before installation begins.
Common Installation Projects
Accessory dwelling units requiring a separate electrical service and utility meter are the most common new installation project we handle. Detached garages being converted to workshops or living spaces require new panel installations sized for the intended use. New construction — residential and light commercial — requires a complete service entrance installation. Guest houses, pool houses, and barn conversions also frequently require standalone panel installations.
Code and Permit Rules
Panel installation for residential ADUs and additions typically requires 100 to 200 amps depending on size and planned loads.

Most new panel installations for ADUs and additions complete in a single day.
