01Why ev charger in Rohnert Park & Cotati is its own thing.
Mid-sized Sonoma County cities along Highway 101 — primarily residential with planned-community origins (Rohnert Park) and a historic small-town core (Cotati). The electrical work that happens here reflects what makes the area distinct. Marin has one of California's highest EV adoption rates. Most installs here are straightforward Level 2 retrofits on existing 100A or 200A panels — but hillside lots and long garage-to-panel runs push cost up. Load-calc is non-optional.
