The houses here

What Oakland houses were wired to carry

In 1978 Oakland's planning department put numbers on the problem. Its Rehab Right manual passed on PG&E's estimate that between 10,800 and 14,500 single-family houses in the city still ran on their original two-wire, 30-amp service, typically split into just two circuits, with thousands more on 30-amp three-wire or 70-amp service. Much of that early two-wire wiring was knob-and-tube, carried on porcelain knobs across framing and through porcelain tubes in it. Many of those houses have been upgraded since, sometimes one circuit at a time, so an electrician opening a wall in a 1920s Oakland bungalow can find several decades of wiring meeting in one box.

The work

Electrical jobs Oakland houses keep generating

Retiring an original small service
A house still on a fuse box or a small early breaker panel usually needs a new meter base, panel and service conductors before it can carry modern loads. The city's 1978 manual called improving the service one of the most effective ways to modernize an old house without harming its architecture, since most of the work happens at the meter and panel rather than across finished rooms. PG&E has to disconnect and reconnect the service, so the electrician coordinates that date with the city's inspection.
Making a 100-amp panel do more
Oakland's own guidance on electrification says that when a panel is 100 amps or larger, the existing service may be enough with panel optimization: load management equipment, breakers used efficiently and appliances chosen for their power draw. That matters because a bigger service means PG&E's Added Load process and its own timeline. A C-10 contractor's load calculation is what settles which path a given house needs.
Backup power for hill shutoffs
The city's solar page frames solar panels and battery storage as a way to keep a home going through PG&E power shutoffs during wildfire season, and points owners to discount and assistance programs, including GRID Alternatives' Energy for All. Whatever the equipment, the electrical side is C-10 work: deciding which circuits the battery keeps alive, adding the transfer or backup panel, and getting a permit and the utility's go-ahead before the system is switched on.
Deciding what to do with knob-and-tube
Rehab Right took a measured view: properly installed knob-and-tube that has not been altered or abused can be safe, but over-fusing damages it, and once extensive problems appear it is nearly impossible to repair in kind because code-acceptable parts are hard to find. That leaves most Oakland owners choosing between replacing the old circuits outright or keeping the sound ones after a survey. A C-10 contractor should test and trace each circuit before anyone decides.

Permits and local rules

City rules and policies that shape Oakland electrical work

Electrical permits and the combination permit
Oakland's Planning & Building Department requires an electrical permit for work on wiring, lights, outlets or circuits. For a house, duplex or ADU, a Residential Building Combination permit may cover the electrical work instead of a separate permit. Applicants are a contractor whose license class suits the work and who holds a current Business Tax Certificate, or the owner. A job that needs no plan check gets its permit as soon as the application is submitted and paid.

Service upgrades for electrification retrofits
Oakland's building electrification program has its own page on service upgrades. It states that where a panel is 100 amps or more, existing service may be sufficient with panel optimization, meaning efficient use of the existing service and breakers with load management technology and suitable appliance selection, and that this avoids added costs from electrification. It also refers to PG&E's Added Load process and links a Redwood Energy report on the subject.

The suspended all-electric rule
In December 2020 Oakland began requiring newly constructed buildings to be all-electric under Municipal Code Chapter 15.37. The city now states that it has been legally directed to suspend that requirement, and it continues work on a Building Electrification Roadmap. For an existing house the practical effect is that switching from gas to electric remains the owner's choice, with the panel question coming first.

Solar and storage against power shutoffs
Oakland's guidance on going solar describes solar power and battery storage as measures that make a home more resilient against PG&E power shutoffs during wildfire season. It lists SunShares discounts for homeowners and GRID Alternatives' Energy for All program, which offers technical help and lower-cost design and installation for single-family homeowners. Those programs supply equipment; the wiring still needs a C-10 contractor and a permit.

Timing

Getting backup power in before fire season

The city ties PG&E's power shutoffs to wildfire season, the dry months when hill neighborhoods are most exposed. A battery or solar-plus-storage system needs a design, a permit, an inspection and the utility's permission before it runs, and PG&E's Added Load process applies if the service has to grow. A hill owner who wants backup in place for the dry months does best to start the conversation in winter or early spring.

Before you hire

What to ask an Oakland electrician up front

Ask for a load calculation showing whether panel optimization can avoid a larger PG&E service.
Check the C-10 Electrical license at cslb.ca.gov and ask whether the business holds a current Oakland Business Tax Certificate.
For a house, duplex or ADU, ask whether the work goes on a combination permit or a separate electrical permit.
In the hills, ask which circuits a battery or generator would keep running during a shutoff, and how it connects.
Ask whether any knob-and-tube circuits will stay in service after the job, and which rooms they feed.

Questions

Oakland panel and wiring questions

Can I add a heat pump in Oakland without upgrading from 100 amps?

Often, according to the city's own electrification guidance. Where a panel is 100 amps or more, Oakland says the existing service may be enough with panel optimization: load management equipment, careful use of breaker space and appliances chosen for lower power draw. Ask a C-10 contractor for a load calculation before applying to PG&E for a bigger service.

Does Oakland still require new homes to be all-electric?

Not at the moment. The 2020 rule in Municipal Code Chapter 15.37 required newly constructed buildings to be all-electric, but the city says it has been legally directed to suspend that requirement. It never applied to replacing appliances in an existing house, where staying on gas or going electric is still the owner's decision.

Our hill house loses power in PG&E shutoffs. What does the city suggest?

Oakland points owners to solar power with battery storage as a way to ride through PG&E power shutoffs during wildfire season, and lists SunShares discounts and GRID Alternatives' Energy for All program. The batteries and panels come from those programs or an installer; connecting them so chosen circuits stay on is permitted C-10 work.

Is the knob-and-tube in my Oakland bungalow automatically dangerous?

Not automatically. The city's Rehab Right manual said properly installed knob-and-tube that has not been altered or abused can be safe, while over-fusing could damage it and extensive faults are very hard to repair in kind. Have a C-10 contractor survey every old circuit, then decide which to replace and which, if any, can stay.

How small were the original electrical services in Oakland houses?

Small by today's standards. Rehab Right reported that most Oakland houses built before the Second World War originally had two-wire, 30-amp, 120-volt service, usually with only two circuits, enough for a refrigerator and a few basics but not for several appliances at once. Others had three-wire service at 30 or 70 amps.
