25 miles from our shop in San Dimas. We know what's behind the walls of Whittier's 1950s postwar housing stock — the undersized panels, the aluminum wiring, the earthquake-loosened connections — and we know how to fix all of it.
Whittier's median home was built in 1956 — meaning most houses in the city came with 60 to 100 amp panels that were never designed for central air conditioning, EV chargers, or the electrical loads of a modern household. We upgrade to 200A and 400A panels, pull the permit through the City of Whittier Building & Safety Division on Penn Street, and get it inspected. If you're in a Friendly Hills ranch home, an East Whittier tract house, or one of the postwar bungalows near Palm Park, this is the single most impactful upgrade you can make to your home's safety and capacity.
Whittier residents on SCE's grid — whether through Southern California Edison directly or through the city's Clean Power Alliance program — are adopting EVs at a growing pace. But charging at home on a Level 2 charger beats any public station. We install Tesla Wall Connectors, ChargePoint units, and NEMA 14-50 outlets with a dedicated 240V/50A circuit. Most older Whittier homes need a panel upgrade first, and we handle both in one project, one permit through the city. If your property falls in unincorporated South Whittier, we pull the permit through LA County instead — either way, you don't touch the paperwork.
If your Whittier home was built between 1965 and 1972, there's a real chance it has aluminum branch-circuit wiring. The CPSC found that homes with this wiring are 55 times more likely to have connections reach fire-hazard conditions. Aluminum expands and contracts with heat more than copper, loosening connections over time — and the 1987 Whittier Narrows earthquake may have further stressed those joints. We inspect every outlet, switch, and junction box, and either pigtail with COPALUM connectors or do a full copper rewire depending on condition. For the Craftsman bungalows and early 1900s homes in the Hadley-Greenleaf and Central Park districts that still have knob-and-tube wiring, we do complete rewires with modern copper and grounded circuits.
Federal Pacific Stab-Lok panels were installed in millions of homes from the 1950s through the 1980s — and with 67% of Whittier's housing stock built during this exact era, they're everywhere in this city. Independent testing found that up to one in four Stab-Lok breakers fail to trip during overcurrent, meaning they won't protect your home when it matters most. A New Jersey court found FPE guilty of fraud for selling breakers that didn't meet UL standards. Some insurance companies in California now refuse to write policies on homes with these panels. We've replaced FPE panels in Friendly Hills, East Whittier, and the tract homes along Whittier Boulevard — and we know exactly what's involved.
Recessed lighting, LED upgrades, ceiling fans, outdoor security lights, and landscape lighting for Whittier homes and businesses. We add outlets, GFCI receptacles in kitchens and bathrooms, and dedicated circuits for home offices and workshops. Older Whittier homes — especially the prewar bungalows near Uptown and Whittier College — are full of two-prong ungrounded outlets and single-circuit rooms that trip the breaker when you plug in a space heater. We bring them up to code with proper grounding and adequate circuit capacity.
We're 25 miles east in San Dimas — about 30 minutes on the 60 freeway. When your breaker won't reset at 2 a.m., you smell burning from a wall outlet, or a Santa Ana wind event brings down your service drop, call us any time. Whittier's aging housing stock means we see a steady stream of emergency calls — panels that overheat during summer heat waves when the AC is running nonstop, aluminum connections that finally arc after decades of thermal cycling, and earthquake-loosened junction boxes that develop intermittent faults. We respond day and night, every day of the year.
Whittier is one of the oldest continuously settled communities in the San Gabriel Valley — founded in 1887 by Quaker settlers who named it after the poet John Greenleaf Whittier and laid out the original streets in a grid around Greenleaf Avenue and Philadelphia Street. That heritage means this city has homes spanning more than a century: from Craftsman bungalows and Spanish Colonial Revival houses in the Hadley-Greenleaf historic district to the postwar ranch homes that filled out Friendly Hills and East Whittier in the 1950s. Every era has its own electrical story, and we've learned to read all of them.
With roughly 86,000 residents and a median home build year of 1956, Whittier is sitting on some of the oldest residential electrical infrastructure in LA County. Two-thirds of the housing stock went up between 1940 and 1969 — before modern electrical codes, before grounding requirements, and before anyone imagined plugging in an EV charger. Add in the legacy of the 1987 Whittier Narrows earthquake, which shook loose wiring connections and cracked masonry throughout Uptown, and you have a city with real, urgent electrical needs. We don't show up guessing. We know what decade your home was built in and what to look for behind the walls.
The Whittier Narrows earthquake on October 1, 1987 measured 5.9 on the Richter scale and hit Whittier harder than almost anywhere else. The Whittier Conservancy was actually formed in response to the earthquake's aftermath. While the visible damage — collapsed masonry, cracked chimneys, broken windows — got repaired, the invisible damage often didn't. Earthquake forces shift junction boxes, loosen wire connections inside walls, and stress conduit fittings. In a home with already-aging wiring from the 1940s or 1950s, that loosening accelerates the degradation. Nearly four decades later, those compromised connections are still in Whittier walls. If your home predates the earthquake and you've never had a thorough electrical inspection, that hidden damage could be a fire risk right now.
Whittier exploded after World War II. Tract developments filled out Friendly Hills starting in 1949, East Whittier spread along Whittier Boulevard, and the neighborhoods around Palm Park and Sorensen Park filled in through the 1950s and early 1960s. These homes were built fast with 60-100 amp panels — adequate for the era when a household had a few lights, a radio, and maybe a window-unit air conditioner. Today you're running central AC through Whittier's hot summers, multiple TVs, a home office, kitchen appliances that didn't exist in 1956, and increasingly an EV in the garage. A 200-amp upgrade gives you the headroom for all of it, and it's the foundation every other electrical improvement depends on.
Whittier takes its history seriously. The city has four locally designated historic districts — Hadley-Greenleaf, Central Park, College Hills, and Earlham — plus over 100 individual historic landmarks overseen by the Historic Resources Commission. These include Craftsman bungalows from the 1910s, Spanish Colonial Revival homes from the 1920s, and early structures dating back to Whittier's founding era in the 1890s. Many still have original knob-and-tube wiring, cloth-insulated wiring, or porcelain fuse boxes. The city's Historic Resources Ordinance, first adopted in 1986 and expanded in 2001, means renovation work needs to respect the character of these structures. We do full electrical rewires in historic Whittier homes that bring them up to modern NEC code without tearing apart the original plaster, trim, or woodwork that makes them worth preserving in the first place.
