30 miles from our shop in San Dimas. Downey built the Apollo command module and the Space Shuttle, but most of its homes still run on the original 1950s electrical systems that were never built for the modern world. We fix that.
The median Downey home was built in 1959 with a 60-100 amp panel designed for a postwar lifestyle that did not include central air conditioning, electric dryers, or EV chargers. The vast majority of Downey's 35,000+ housing units are sitting on electrical systems that are nearly 70 years old. We upgrade to 200A and 400A panels, pull the permit through the City of Downey's Building & Safety Division at 11111 Brookshire Avenue, and get it inspected. If you are in North Downey near Gallatin Road or in a South Downey tract home off Firestone Boulevard, this is likely the most critical upgrade your home needs.
Downey residents can choose between Southern California Edison and the Clean Power Alliance for their electricity, and either way, charging at home on a Level 2 charger overnight beats hunting for a public station. We install a dedicated 240V/50A circuit and mount your charger — Tesla Wall Connector, ChargePoint, Ford Connected, whatever you drive. The problem is that most Downey homes need a panel upgrade before they can support the extra 50-amp load. We handle both in one project, one permit through the City of Downey.
Downey's postwar housing boom left the city with thousands of homes that still have their original cloth-insulated wiring from the late 1940s and 1950s. Over decades, the rubber and fabric insulation becomes brittle, cracks, and crumbles away — leaving bare conductors inside your walls. Homes in Northeast Downey near Furman Park and the older sections of Northwest Downey around Independence Park are especially likely to have this issue. We do complete rewires with modern copper and grounded circuits, working carefully through plaster walls and original construction without tearing your home apart.
Federal Pacific Stab-Lok panels were installed in millions of homes from the 1950s through the 1980s, and Downey's housing stock falls right in the center of that window. Independent testing found these breakers fail to trip during overcurrent up to 60% of the time — which means they will not protect your home when it matters most. Zinsco panels, another common brand from the same era, have similar documented failure rates with breakers that melt to the bus bar. Both are found throughout Downey's tract home neighborhoods. Some insurance companies are now refusing to cover homes with either brand. We replace them with modern panels that actually work.
Recessed lighting, LED upgrades, ceiling fans, outdoor security lights, and landscape lighting for Downey homes and businesses. Most 1950s Downey homes were built with a fraction of the outlets modern life requires — two-prong, ungrounded, and nowhere near enough of them. We add outlets, install GFCI receptacles in kitchens and bathrooms to meet current code, and run dedicated circuits for home offices, garage workshops, and media rooms. If you are in a Downtown Downey mixed-use building near the Downey Theatre or a commercial space along Firestone Boulevard, we handle commercial lighting and electrical buildouts as well.
When your breaker will not reset, you smell burning from an outlet, or a summer heat wave pushes your aging panel past its limits — call us any time, day or night. Downey sits in the LA basin where summer temperatures regularly hit the 90s, and 70-year-old panels in tract homes across North Downey and South Downey were never designed to handle modern AC loads running for months straight. We have seen the pattern: overloaded panels, overheated connections, and after-hours calls that spike every summer. We serve all Downey zip codes — 90240, 90241, and 90242.
Downey is a city of roughly 111,000 people with a housing stock that tells a very specific story. This was farmland and orange groves until the postwar boom hit in the late 1940s and 1950s. North American Aviation opened its massive plant here, aerospace workers flooded into the area, and developers built thousands of tract homes as fast as they could to keep up. Those homes — the ranch-style houses in North Downey, the compact stucco homes in South Downey, the mid-century builds in Northeast Downey — are still standing. And most of them still have the original 60-year-old electrical systems inside the walls.
The city that engineered the Apollo command module and the Space Shuttle is now a city where the average home is running on electrical infrastructure from the Eisenhower administration. Between the shift to electric vehicles, the growing demand for home AC in Southern California summers, and insurance companies cracking down on outdated panels — Downey homeowners are facing real, urgent electrical upgrade needs. We are based in San Dimas, about 30 miles and 35 minutes away, and we know this housing stock inside and out.
Downey's median home was built in 1959 — right in the heart of the postwar construction boom when developers were building tract homes at breakneck speed across southeast LA County. Most of these homes used cloth-insulated wiring, where rubber-coated conductors were wrapped in a fabric braid. The problem is that after 65-70 years, the rubber hardens, cracks, and the cloth braid frays. What you end up with is bare copper wire sitting inside your walls with no effective insulation left. This wiring does not trip a breaker — it arcs silently at junction points, behind outlets, and inside boxes. Unlike aluminum wiring, which gets more attention, cloth wiring fails through slow degradation that is hard to detect until something goes wrong. If your Downey home was built in the 1950s, the wiring condition needs to be assessed.
From 1948 through 1999, the massive North American Aviation plant (later Rockwell, then Boeing) dominated Downey. At its peak, the facility employed over 30,000 people and built everything from the Apollo command module to the Space Shuttle orbiter. That plant is gone now — replaced by the Promenade at Downey shopping center, Kaiser Permanente hospital, and the Columbia Memorial Space Center. But the legacy shaped the city's electrical infrastructure. The residential neighborhoods surrounding the plant — the tract homes in South Downey and Northwest Downey — were built specifically to house aerospace workers and their families. Those homes were wired for the electrical demands of 1955, not 2026. The industrial load is gone, but the residential grid and the homes connected to it are still running on mid-century systems.
Over seven decades, many Downey homeowners have added rooms, converted garages, enclosed patios, and built ADUs — often without pulling permits through the City of Downey Building & Safety Division. The electrical work in these additions is frequently substandard: undersized wire tapped into already-overloaded circuits, missing junction boxes, no GFCI protection, and connections made with electrical tape instead of proper connectors. We see this constantly in South Downey and the older sections near Downtown Downey. When we do a panel upgrade or rewire, we trace every circuit in the house and identify any unpermitted or unsafe wiring that needs to be brought up to code. The permit process through the City of Downey is straightforward — we handle everything from the application through inspection.
