Short answer
Yes — an electrical panel upgrade (and subpanels and EV charger circuits) requires a permit and inspection in California, and a service upgrade coordinates with the utility. Because it's your home's main power, the inspector verifies it's safe and to code. A licensed electrician pulls the permit for you.
Why panel work is always permitted
Your electrical service panel is the point where utility power enters and distributes through your home. Get it wrong and the consequences are severe — shock, arc-flash, or fire. Because the stakes and the code requirements are high, the building department requires a permit and an inspection, and a service-size upgrade also involves the utility to safely disconnect and reconnect power.
What the inspector is checking
- Correct service size and main breaker.
- Proper grounding and bonding.
- Correct breaker sizing and wiring.
- Required AFCI/GFCI protection.
- Adequate working clearance around the panel.
[GATHER: confirm the exact inspection checklist, permit fees, utility coordination, and turnaround for the specific SLO or Santa Barbara jurisdiction.]
Subpanels and EV chargers count too
It's not just full service upgrades. Adding a subpanel or a dedicated 240V circuit for an EV charger generally requires its own permit and inspection. If you're not sure whether your panel can even support more load, start with the signs it needs an upgrade.
Why skipping the permit costs more
Unpermitted electrical work can void insurance, fail at the worst time, and surface as a serious problem when you sell — sometimes forcing a tear-out and re-inspection. With your home's main power involved, permitted, licensed work isn't red tape — it's the safeguard.
How Homepatible handles it
For panel and circuit work, we pull the permit, coordinate with the utility when needed, and schedule the inspection as part of the job. See the full permits & code compliance guide for how this works across HVAC, plumbing, and electrical.
