Modern 200A service to support EVs, induction cooking, heat pumps, and future electrification. In Tiburon, CA: High-end custom homes 1970s-present.

01Why panel upgrade in Tiburon is its own thing.
Affluent peninsula town across Richardson Bay from Sausalito — known for waterfront and hillside estates with sweeping Bay and San Francisco views. The electrical work that happens here reflects what makes the area distinct. Most pre-1985 homes here ship with 100A service that's now undersized for modern electrification. The conversation usually starts with a single trigger (EV install, induction range, heat pump) and ends with a service upgrade to make all of it fit.
Common drivers we see for panel upgrade work in Tiburon: EV charging plans, induction range install, heat pump conversion, panel age (Federal Pacific/Zinsco/Pushmatic replacement), insurance carrier requirements, electrification of natural-gas appliances. Each creates a different scope conversation — we walk every project before quoting so the number reflects the actual work.
02What working here actually looks like.
Geography matters more here than people often realize. Steep hillsides dropping to the bay. Long service runs from street to homes set on the slopes. Salt-air corrosion on exterior equipment. Salt-water environment shortens outdoor metal hardware lifespan.
Utility grid context: PG&E distribution from peninsula substations. Service mostly underground in newer subdivisions, overhead in older sections. Wind exposure creates occasional service-drop damage.
Permit jurisdiction for this scope: Town of Tiburon Building Department. Design review applies broadly; permit timelines run 4-8 weeks for substantial work.
03How a panel upgrade project here goes.
Typical panel upgrade project in Tiburon runs 1-2 days from kickoff to final inspection. Pricing range: $3,500-$6,500, with variation driven by access, existing conditions, and permit complexity.
The sequence we follow: Load calculation against current and planned future loads → PG&E service disconnect coordination → Permit pull through the AHJ → Panel removal and new install (1-2 days typical) → PG&E reconnect and meter coordination → AHJ rough and final inspection.
We pull permits as part of the standard scope on permitted work, coordinate AHJ inspections, and don't leave site until the work is functional, tested, and signed off.
