Wildfire in the hills
The 1991 Oakland Hills firestorm destroyed thousands of homes. Hill residents face high fire danger and PG&E power shutoffs during extreme weather, which make backup power valuable.

The Oakland electrical guide
History, housing, weather and rules that shape electrical work in Oakland, CA.
The Hayward Fault
The Hayward Fault runs directly beneath Oakland’s foothills, passing near neighborhoods such as Montclair, Dimond and the Oakland Zoo. Scientists consider it one of the most dangerous faults in the country because of the dense population around it. Earthquake preparation for homes includes bolting houses to foundations, bracing cripple walls, strapping water heaters and making sure everyone knows where the main breaker and gas shutoff are.
The 1991 firestorm
On October 20, 1991, a wind-driven fire swept through the Oakland and Berkeley hills, destroying about 3,000 homes and killing 25 people. Neighborhoods such as Hiller Highlands, Upper Rockridge and the area around Broadway Terrace were rebuilt over the following years. Rebuilt homes have modern wiring, but residents remain in a high fire hazard zone, where defensible space, ember-resistant construction and well-maintained electrical equipment matter.
Power shutoffs in the hills
During extreme fire weather, PG&E may shut off power to parts of the Oakland Hills to reduce the risk of its lines sparking fires. Shutoffs can last a day or more. Residents increasingly install battery systems, often paired with solar, or generators with interlocks so they can keep refrigerators, lights, medical devices and internet running safely.
West Oakland Victorians
West Oakland grew in the late 1800s as a railroad terminus and has hundreds of Victorian and Italianate homes, many of them now restored. Restorations usually replace knob-and-tube wiring, upgrade tiny services and add circuits for modern kitchens and baths. The neighborhood was also home to the Cypress Structure freeway, which collapsed in the 1989 Loma Prieta earthquake.
Rockridge and Temescal
Rockridge and Temescal have brown-shingle, Craftsman and period revival homes from the 1900s through the 1920s, popular with families who remodel and expand. Many still have original wiring hidden in walls, and remodels routinely require service upgrades. Detached garages along narrow driveways often need new feeders for EV chargers or workshops.
Grand Lake and Adams Point
Grand Lake, Adams Point and the neighborhoods around Lake Merritt have period revival homes and many apartment buildings from the 1910s through the 1960s. Apartments often have small services and crowded meter banks, and owners upgrading them must coordinate with tenants and follow the city’s tenant protection rules.
Fruitvale and East Oakland
Fruitvale, home to a large Latino community, and other East Oakland neighborhoods have Victorian cottages, bungalows and post-war homes, many owned by families for generations. Older homes commonly need service upgrades, grounded circuits and corrections of unpermitted additions. Community programs sometimes help income-qualified homeowners with electrification and safety repairs.
Soft-story retrofit program
Oakland adopted a mandatory retrofit program for many soft-story apartment buildings, those with large garage openings or weak ground floors, built before 1991. Retrofitting the ground floor often requires relocating meters, panels and wiring attached to walls being strengthened, so electricians work alongside engineers and contractors on these projects.
Montclair and the hill homes
Montclair and other hill neighborhoods have homes on steep lots with winding roads, long driveways and mature trees. Many have long service runs, outdoor lighting on stairways and decks, and equipment exposed to falling branches. Hill homes benefit from clearing vegetation around electrical equipment and backup power for shutoffs.
Ava Community Energy
Ava Community Energy, created as East Bay Community Energy, supplies electricity to most Alameda County residents with an emphasis on renewable sources and offers programs for electrification. PG&E still handles delivery, so the electricity bill includes charges from both.
Electrification goals
Oakland has adopted rules requiring new buildings to be all-electric and encourages existing homes to switch from gas. Converting a gas furnace, water heater, stove and dryer to electric often requires a service upgrade, especially in older homes with 60- or 100-amp services. Load-management devices can sometimes reduce the size of the upgrade needed.
In-law units and ADUs
Oakland has many in-law units in basements and garages, and state law encourages new accessory dwelling units. Legalizing or building these units requires adequate circuits, alarms, often a subpanel and sometimes a separate meter.
Lake Merritt to the bay
Neighborhoods near the estuary and the bay, such as Jack London Square and parts of West Oakland, include converted warehouses and new apartments. Residents work with management for electrical changes, and low-lying areas face flooding concerns as sea levels rise.
Solar, batteries and EVs
Rooftop solar and batteries are popular in Oakland, especially in the hills. EV ownership is high, and a load calculation determines whether a charger can be added without upgrading the service.
Findings during sales
Inspection reports for older Oakland homes frequently note knob-and-tube wiring, undersized services, ungrounded outlets, outdated panels and unpermitted basement units. Written estimates help buyers negotiate.
Common Oakland projects
Typical work includes rewiring older homes, service upgrades for electrification, battery and generator installations for the hills, seismic retrofit coordination, ADU wiring, EV chargers and smart home systems.
Piedmont Avenue and the Piedmont border
Piedmont Avenue, a busy shopping street lined with 1910s homes and apartments, runs along the edge of the separate city of Piedmont. Homes on the Oakland side follow Oakland’s permit process, while houses a block away inside Piedmont answer to a different building department with its own rules. Many homes in this area are large shingle and Colonial Revival houses whose original wiring was extended room by room over a century, leaving multiple small panels that electricians consolidate during remodels.
Dimond, Laurel and the foothill flats
The Dimond and Laurel districts sit along the base of the hills near the Hayward Fault, with 1920s bungalows, storybook cottages and small apartment buildings. Many homes have raised foundations with crawl spaces, where wiring runs exposed beneath the floor. Seismic retrofits that bolt houses to foundations and brace cripple walls often reveal old splices and loose cable, and coordinating electrical repairs with that work saves opening the crawl space twice.
Tree canopy and storm season
Oakland’s hills are covered in eucalyptus, pine and oak, and winter atmospheric river storms bring saturated soils and strong winds that topple trees onto service drops. Hill residents also manage vegetation for fire safety, which reduces the number of limbs that can fall on lines. When a drop is torn away, the mast and meter base on the house must be repaired by an electrician before PG&E restores service.
Tenant protections and electrical work
Oakland’s rent and just-cause eviction rules mean landlords upgrading apartment wiring must give proper notice, schedule shutdowns carefully and avoid displacing tenants. Electricians experienced with occupied buildings plan work unit by unit to keep disruptions short.
