Electrician quotes in San Jose, compared line by line

San José requires an electrical permit for electrical work. Depending on the project and property, the permit may be available online; if not, the project needs plans. A City inspector checks the work for code compliance.

Upgrading the main service panel of a home needs an electrical permit. Load calculations and undergrounding are generally not required, unless more load is being added and the inspector asks for the calculation, or the service entrance is underground or must be put underground.

Panel placement: the meter sits 48 to 75 inches above the ground, with 66 inches preferred. The panel needs a clear space 30 inches wide and 36 inches deep in front, and at least 6 feet 6 inches of headroom.

Where branch circuit wiring is modified, replaced or extended, listed combination-type arc-fault (AFCI) breakers are required. Where service equipment is replaced, a Type 1 or Type 2 surge-protection device must be provided.

Grounding: if the underground metal water pipe is the only grounding electrode, a supplemental electrode must be added. If a single ground rod is the only electrode, the contractor must document a resistance to earth of 25 ohms or less before final approval.

Service equipment rated above 225 amps needs a document from the utility stating the maximum available short circuit current, before the City approves the meter release.

A rewire must follow the California Electrical Code and be done by a licensed electrician. Main service panels, subpanels and feeders are sized for the calculated load, with a minimum of 100 amps. Dedicated circuits are required for dryers, dishwashers, ranges, air conditioners, heat pump water heaters and electric vehicle charging stations.

A Level 1 car charger on a standard 120-volt outlet needs no permit unless it needs a new outlet. A Level 2 charger on a 240-volt circuit needs an electrical permit. When the service panel is rated 125 amps or less, the permit package must include a load calculation with 125 percent of the charging load.

Only property owners and licensed contractors can apply for an online permit. A contractor needs a valid San José business tax certificate and can only apply for permits that match the license class. The online list for single-family homes includes new subpanels, rewires, car chargers and service changes up to 400 amps, the last one limited to like-for-like replacements in the same location with no change to exterior finishes.

The City recommends that a licensed contractor be the applicant. Whoever signs the application is responsible for everything done under the permit.

The C-10 license covers installing wires, fixtures, appliances, raceways and conduits, and solar photovoltaic cells.

San Jose is inside the Bay Area Air District. Its draft water heater amendments of July 14, 2026 would exempt homes where electrical limits make the switch hard, such as a panel below 100 amps, not enough panel capacity, or a new line of more than 50 feet.

Age. Of 345,884 housing units in San Jose, 203,522 were built in 1979 or earlier and 18,528 in 1939 or earlier, according to the 2024 American Community Survey. Any wiring and panel that were never replaced date from those years.

Small panels. Fixr says homes of the 1950s usually got 50 or 60 amps, and homes of the 1960s and 1970s often no more than 100 or 150 amps. It says 200 amps became the standard in the 1980s.

Wiring without a ground. This Old House says houses built in the 1920s or 1930s often lack grounding, which raises the effort and price of a rewire compared with newer construction.

New loads. This Old House lists air conditioners, a second oven, a finished garage, a hot tub, a room addition and an electric vehicle charger as reasons to recalculate the electrical load before choosing a panel size.

Panels with a known history. This Old House names Federal Pacific Electric and Zinsco panels among the outdated panels that call for an upgrade.

Hidden extras. The same guide says labor is often the largest part of a panel upgrade, and the price rises with rewired circuits, service line work, tight spaces and local code requirements.

C-10 license number and a current San José business tax certificate, since the City requires both before a contractor can pull a permit.

Who applies for the permit, online at SJPermits.org or through plan review, and is the permit fee part of the price?

Panel work: amperage of the old and the new panel, the brand, combination AFCI breakers, a surge protection device, and how the grounding is done.

Who schedules the City inspection and the meter release, and how many hours or days the power is off.

Car charger or heat pump water heater: circuit size, the load calculation at 125 percent of the charging load, and the UL listing of the charger.

Rewire: which rooms get opened, whether every circuit gets a ground, and who patches and paints the drywall.

Minimum charge, trip fee, hourly rate, and the surcharge for a night or weekend call, all in writing.

Labor and parts warranty in years, plus the earliest start date.
