New Panel Installation for New Construction, ADUs, Home Additions & Service Upgrades
Whether you're building a new home, adding an ADU, finishing a garage, or establishing a new electrical service, West Coast Electric installs code-compliant electrical panels that are built to last. C-10 licensed, fully insured, and family-owned since 1998.
Every new home or structure requires a main electrical panel. We size and install the right panel for your load requirements from the ground up.
Adding a detached ADU or converting a garage to living space often requires a dedicated subpanel or new service. We handle all permitting and SCE coordination.
Major additions — extra bedrooms, expanded kitchens, sunrooms — often exceed your existing panel capacity. We install new panels or subpanels to support the added load.
Moving to a new property or starting fresh after a major renovation? We establish new electrical service with properly sized panels for current and future needs.
New 200-amp or 400-amp main service panel installations for new construction, major renovations, or when establishing new utility service.
Add a subpanel to serve a detached garage, workshop, ADU, or addition without running all circuits back to the main panel.
Temporary electrical service panels for construction sites — properly permitted and compliant with California code.
Panel installation pricing depends on panel amperage, number of circuits, service entrance requirements, and whether trenching or conduit runs are needed. We provide a free detailed estimate before any work begins.

Yes — all new panel installations in California require a city building permit and inspection. West Coast Electric handles the permit application, coordinates with your city, and schedules the final inspection on your behalf.
Most new homes require a 200-amp panel. Larger homes over 3,000 sq ft, homes with multiple HVAC systems, EV chargers, and electric appliances may benefit from a 400-amp service. We assess your planned loads and recommend the right size during your free estimate.
Yes — ADU subpanel installation is one of our most common projects. We install a properly sized subpanel fed from your main panel with all required disconnects, grounding, and permits in place.
A standard new panel installation takes 4–8 hours of on-site work. The full timeline including permit approval and SCE coordination is typically 2–4 weeks from estimate to final inspection.
