Electrical panel upgrade permits in San Francisco, CA
General California guidance last updated May 22, 2026 · San Francisco data verified August 9, 2026
What electrical contractors need to know about pulling a electrical panel upgrade permit in San Francisco (San Francisco County).
Short answer
In California, an electrical service or panel upgrade always needs an electrical permit and an inspection, and almost always requires utility coordination for the temporary disconnect. It is pulled by a licensed C-10 contractor under the California Electrical Code (Title 24, Part 3). Common drivers: EV chargers, heat pumps, solar/battery, ADUs, and replacing legacy/recalled panels (Federal Pacific, Zinsco, Pushmatic).
San Francisco accepts submittal through the Permit Services at DBI (online permits and tracking) and has adopted the SF Building Code (2025 edition, amending the 2025 California Building Code). Fee details and sources are below.

The general picture in California
A panel upgrade changes the building's electrical service — bumping the amperage (typically 100A → 200A, sometimes 225/400A), replacing the panel and meter, and often re-pulling the service lateral or mast. Because the work touches utility infrastructure and the main overcurrent device, it requires an electrical permit, a load calculation, a single-line diagram, and coordination with the utility for power-cut and reconnect. Grounding and bonding must meet the current code cycle (often a new ground-rod system in addition to the UFER), and AFCI/GFCI updates may be required on circuits being touched or extended.

Typically needs a permit
Electrical panel upgrade itself triggers a permit in nearly every California jurisdiction, San Francisco included. San Francisco-specific variations are confirmed with the issuing department above.
Usually doesn't (general norm)
- Replacing a single breaker for one of the same type and rating
- Tightening lugs or replacing a feeder bus cover (maintenance, not modification)
- Re-labeling the panel directory
Documents & plans generally required
- Electrical permit application
- Contractor license and city business registration
- Load calculation per NEC Article 220 (existing load + new loads)
- Single-line diagram showing the new service size, meter, panel, main breaker, and grounding-electrode system
- Site plan with panel/meter location and the service drop or lateral route
- Cut sheet for the new panel (listing, AIC rating, bus rating, number of spaces)
- Utility coordination forms (PG&E, SCE, LADWP, SDG&E — varies by service area)
Common reasons electrical panel upgrade applications get bounced
Code-rooted patterns across California — not a San Francisco-specific rejection rate.
- Load calculation missing, incomplete, or not matching the proposed service size
- No single-line diagram, or the diagram doesn't reflect the proposed work
- Grounding/bonding details missing (UFER + supplemental ground rods, bonding jumpers)
- AIC rating of the new equipment not coordinated with the utility's available fault current
- Service-conductor sizing not matching the new main breaker
- Working clearances around the panel not shown (NEC 110.26)
The inspection sequence
A typical order — the number of stops and exact sequence vary by jurisdiction and scope.
- 1Rough/service inspection before energization, with the panel set and grounding visible
- 2Utility coordination for temporary disconnect, meter pull, and reconnect
- 3Final inspection with the panel labeled, all circuits identified, and the service energized
Licensing — who can pull it
Panel and service upgrades in California are performed by a C-10 (Electrical) licensed contractor; a B (General Building) contractor may pull within a larger project under CSLB rules. The licensed contractor pulling the permit typically also coordinates the utility cut and reconnect.

Frequently asked questions
When does California require a panel upgrade?
When the load calculation shows the existing service can't carry the new connected load — most often triggered by EV chargers, heat pumps, solar/battery, ADUs, or replacing a recalled panel brand (Federal Pacific, Zinsco). The upgrade is permitted as a single project even when it bundles multiple drivers.
Do I need to coordinate with the utility?
Yes — service upgrades require utility coordination for the temporary disconnect, meter pull, and reconnect. PG&E, SCE, LADWP, and SDG&E each have their own application and lead time; the contractor typically handles this in parallel with the city permit.
Can I keep the same panel location?
Generally yes, if the location still meets NEC 110.26 working clearances and the meter remains accessible to the utility. Moving the panel can simplify the install or be required when the existing location is non-compliant.
Does the panel upgrade trigger AFCI/GFCI updates on existing circuits?
Generally only the circuits being touched, extended, or replaced have to meet the current code cycle's AFCI/GFCI rules — existing circuits left in place are usually grandfathered. Some jurisdictions are stricter on this; confirm with the city.
