Running an electrical contractor in San Francisco

San Francisco's cool, foggy summers mean heating has always mattered more than cooling, though warmer spells now bring more cooling and heat pump questions. The city is full of century-old Victorians, Edwardians and multi-unit buildings, where tight access, old drain lines and knob-and-tube surprises are normal. Most of San Francisco falls in California Energy Commission climate zone 3, which matters for energy-code work; check an exact address with the Commission's climate zone search. The utilities are PG&E (with CleanPowerSF as a generation option) for power and PG&E for gas.

Electrical work here is less seasonal than HVAC: service calls for tripping breakers and dead circuits, plus a steady stream of projects that start as simple questions, like an EV charger, a heat pump or an induction range that the old panel cannot carry.

How many electrical contractors work in San Francisco

The Contractors State License Board's License Master file (downloaded November 13, 2026) lists 565 C-10 Electrical licenses in good standing with a mailing address in San Francisco, out of 26,895 statewide (2.1%). That counts license holders, not trucks: some are one-person shops and some dispatch dozens of techs, and companies based in nearby cities work San Francisco too. Either way, a homeowner in San Francisco has a long list to call, and the first shop that answers and books usually gets the job.

Permits and the rules that shape the job

San Francisco is a combined city and county, so the San Francisco Department of Building Inspection (DBI) handles permits across the whole city.

Panel and service upgrades need a permit and, for a new or bigger service, coordination with PG&E to disconnect, reconnect or upsize the service, which adds weeks you need to plan around. A load calculation up front tells you whether the EV charger fits on the existing panel or the job is really a service upgrade.

Answering every call

When the line is busy or it is after hours, the SWITCHBOARD AI receptionist answers in your shop's name and books the job while the caller is still on the line. You teach it your answers: which parts of the city you cover, your trip charge, the jobs you do not take. A phone menu can send real emergencies to the on-call tech, and when it does not know something, it takes a name, number and problem for a callback instead of guessing. Every call is transcribed and lands in one inbox with your texts, email and web leads. More in how to stop losing after-hours calls.

Getting around San Francisco

Parking, hills and narrow streets make every stop slower than the miles suggest, so fewer, better-planned stops per tech is the goal. Plan the day rebuilds tomorrow's routes to cut driving, keeping promised arrival windows, skills and pinned visits, and nothing moves until you press Apply. Who's free ranks the nearest tech with the time and skills for an urgent call. See how Plan the day works.

Job Walk builds Good, Better and Best from your own Price Book (charger only, charger with a load manager, charger with a panel upgrade) with live margin, and staged invoicing keeps the deposit, the utility wait and the final on one job number. See how to price a panel upgrade and how staged invoicing works.

The whole crew gets a login with no seat fees, and every feature is included. Setup is done with you on a call, and the goal is to be live in about one to two weeks. Pricing is quoted per shop on a 30-minute walkthrough: book one here, or try the sandbox first.
