Yes, a subpanel is a common solution for detached garages and ADUs in Berkeley and across the East Bay. It gives the structure its own set of breakers and keeps control local to that space.

The right size depends on your existing panel capacity and total electrical load, which we assess before any work begins. Most EV charger setups in Oakland and Berkeley require a dedicated 40- to 60-amp circuit fed from a properly sized subpanel.

Subpanel installations in Berkeley are subject to the Berkeley Electrical Code, which is based on the California Electrical Code, and typically require a permit and inspection. We handle the work to meet those code requirements.
