When Should You Upgrade Your Electrical Panel?
If your lights dim, breakers trip often, or you’re adding an EV charger or solar system — your panel may need an upgrade. Homes built before 1990 often have panels that are too small for today’s power needs. Businesses may need more capacity for new systems or equipment.
In Alameda, panel upgrades require a permit and sometimes coordination with PG&E.
For full rules, see our guide to electrical permit rules in Alameda.
Do You Need a Permit for a Panel Upgrade?
Yes. Any panel upgrade — even if you’re keeping the same location — requires an electrical permit in Alameda. The city checks for safety, grounding, amp rating, and meter location.
If the upgrade affects the power supply, PG&E must also be notified before the work begins.
Panel Upgrade Process (Step-by-Step)
Here’s how the process works in Alameda:
- Apply for an electrical permit using the City of Alameda Permit Portal.
- Submit panel specs and load calculations if required.
- Contact PG&E through their Service Planning Portal if your upgrade increases amperage or changes the meter location.
- Install the new panel after permit approval.
- Schedule the city inspection through the permit portal.
- Get final PG&E reconnection if your service was shut off.
Panel-only upgrades can take 1–2 weeks. If PG&E must upgrade their equipment, allow 3–5 weeks for coordination.
How Much Does It Cost?
Permit fees for panel upgrades in Alameda typically range from $200 to $400 depending on the panel size and service change. The full cost (including labor and parts) depends on amperage and location.
| Panel Size | Typical Permit Fee |
|---|---|
| 100 Amp | $200 – $250 |
| 200 Amp | $250 – $350 |
| Above 200 Amp or relocated | $350 – $400+ |
Do You Always Need PG&E?
PG&E must be involved if:
- You’re increasing your service size (e.g. 100 amp to 200 amp)
- You’re moving the meter
- You’re installing solar with grid backfeed
- The main shutoff affects PG&E’s equipment
PG&E approval takes time. Start early to avoid delays. Visit their Electric Service Planning Page for more info.
