Whole house standby generator installation in San Francisco, California
A generator is only as good as its transfer switch and its sizing. Undersized units in San Mateo County homes trip on the first AC start; oversized ones cost more to buy and run. We measure what you need to keep running, then specify from there.

Generator Installation across San Francisco
We cover every part of San Francisco — SoMa, Bernal Heights, the Richmond and the Mission included — along with the neighboring communities of Millbrae and San Bruno.
San Francisco sits in San Mateo County, and the electrical work here reflects that mix: older housing stock that needs grounding, capacity and device upgrades, alongside newer construction that simply needs more circuits than it was built with. Crews route through the Peninsula daily, so travel time to a call in San Francisco is short.

|---|---|
| Transfer switch scope | Whole-panel switching costs more than an essential-circuits sub panel. |

Dan K.San Francisco, CAGenerator Installation in San Francisco — questions we get asked
What size generator do I need in San Francisco?
It depends on whether you want the whole house or essential circuits. Many San Francisco homes are well served by a mid-size air-cooled unit with load management; all-electric homes with heat pumps and EVs need more. We run the calculation before quoting.
How often does a standby generator need service?
Plan on annual service and a monthly self-test, which most controllers run automatically. Oil, filters and battery are the usual wear items.
Will a generator run my EV charger?
Technically yes, practically it is a poor use of fuel. Most owners exclude EV charging from the backed-up loads and keep the capacity for HVAC and refrigeration.
Can you install a transfer switch for a generator I already own?
Yes. For portable units, an interlock kit or a manual transfer switch is usually the right answer, and it is far cheaper than a standby install.
Do generators need permits in San Francisco?
Standby generator installations involve electrical and often mechanical permits in California, plus setback and noise rules that vary by San Mateo County jurisdiction. We handle the electrical permitting and flag local requirements early.
