ADUs and garage conversions
Adding an accessory dwelling unit usually needs a load calculation, a subpanel and often a service upgrade coordinated with LADWP or SCE.
Electrical Panel UpgradeLocal guide
The Los Angeles electrical guide
History, housing, weather and rules that shape electrical work in Los Angeles, CA.
Working with LADWP
Inside city limits, the Los Angeles Department of Water and Power handles service connections, meter work and outage restoration. LADWP has its own service requirements and scheduling for panel and service upgrades, which can take time during busy periods, so electricians typically start the utility process early. Neighboring cities such as Burbank, Glendale and Pasadena have their own municipal utilities, and much of the surrounding county is on Southern California Edison.
Neighborhood notes
Silver Lake and Echo Park climb steep hills with homes from the 1910s through the 1960s. Los Feliz has Spanish Revival and Craftsman homes, and Highland Park and Eagle Rock are known for Craftsman bungalows. In the San Fernando Valley, Sherman Oaks, Van Nuys and Reseda are largely post-war ranch homes. On the Westside, Mar Vista and Venice mix older cottages with modern rebuilds, and South Los Angeles has many early-1900s homes in need of updates.
Historic Preservation Overlay Zones
Los Angeles protects historic neighborhoods through Historic Preservation Overlay Zones, which cover areas in Highland Park, Angelino Heights, Hancock Park, Jefferson Park and elsewhere. Exterior changes, including new meter locations, visible conduit or solar visible from the street, may need HPOZ review. Electricians plan routes that keep equipment out of sight when possible.
Hillside lots and long service runs
On steep hillside lots, garages often sit at street level while the house is far above or below, connected by stairs. Running power to a garage EV charger, a hillside ADU or exterior lighting may mean long trenches through retaining walls and slopes. The city’s hillside rules can affect where trenches and equipment can go.
Soft-story retrofits
Los Angeles requires seismic retrofits for many wood-frame apartment buildings with weak ground floors, often called soft-story buildings, following the city’s 2015 ordinance. Retrofitting usually involves opening walls and ceilings around parking areas, where electrical lines, meters and panels may need to be relocated or protected. Coordinating the electrician with the structural contractor saves rework.
Rebuilding after the Palisades fire
The January 2025 Palisades Fire destroyed thousands of homes in Pacific Palisades and neighboring areas. Rebuilding gives owners a chance to install larger services, all-electric heating and cooking, EV charging, solar and batteries from the start. The city set up expedited permitting for fire rebuilds, but utility service connections still require early coordination with LADWP.
The Northridge earthquake
The January 17, 1994 Northridge earthquake caused widespread damage across the San Fernando Valley and beyond. Its lessons shaped building codes and retrofit programs. After any significant quake, check for meter bases pulled from walls, damaged masts and gas smells, and keep clear of damaged equipment.
Heat in the Valley
The San Fernando Valley regularly runs far hotter than the coast, and Woodland Hills hit 121 degrees in September 2020, a county record. Older Valley homes that relied on window units are adding central air and heat pumps, which often require panel upgrades.
The ADU capital of California
Los Angeles permits more accessory dwelling units than any other city in the state. Garage conversions and backyard units need properly sized feeders or separate meters, smoke alarms, and room in the main service for both households’ air conditioning and appliances.
Typical Los Angeles electrical jobs
Common requests include panel and service upgrades for ADUs, EV chargers and heat pumps, knob-and-tube replacement, solar and battery installations, earthquake repairs, hillside trenching for garage circuits and lighting upgrades.
Very high fire hazard zones
Large parts of Los Angeles, from the Santa Monica Mountains to the Verdugos and the San Gabriel foothills, are designated Very High Fire Hazard Severity Zones, where the fire department enforces brush clearance around homes. Keeping vegetation away from meters, panels, service drops and outdoor equipment is part of that clearance. Homes in these zones benefit from battery backup during red-flag warnings.
Hollywood Hills and the canyons
Homes in the Hollywood Hills, Laurel Canyon and Beachwood Canyon sit on narrow, winding streets with steep driveways and limited access for trucks. Electrical projects need planning around parking, material delivery and hillside trenching, and many homes have small original services feeding large renovations.
Rent-stabilized apartment buildings
Most Los Angeles renters live in older apartment buildings, many covered by the city’s rent stabilization rules. Electrical upgrades in occupied buildings require planning around tenants, and owners must follow city rules on notices and temporary relocation when work affects units.
South Los Angeles homes
South Los Angeles neighborhoods such as West Adams, Jefferson Park and Leimert Park have Craftsman and Victorian homes from the early 1900s, many in historic overlay zones. Original wiring, small services and decades of patchwork additions are common.
Santa Ana winds
Dry Santa Ana winds in fall and winter bring down trees and power lines, raise wildfire risk and can trigger utility power shutoffs in surrounding Edison territory. Secure masts and service drops and backup power help homes through wind events.
Insurance and older wiring
With home insurance increasingly difficult to obtain in California, some insurers look closely at older wiring and panels. Replacing knob-and-tube and problem panels can help a home qualify for coverage.
Permits from LADBS
The Los Angeles Department of Building and Safety issues electrical permits and inspects work inside city limits, with online permits available for many simpler jobs. Larger projects, ADUs and work in hillside or historic areas may need plan review. Because the county contains dozens of separate cities, it is important to confirm that your address is actually in the City of Los Angeles before applying.
Older apartment wiring and window units
Many older Los Angeles apartments still have small services per unit, and tenants rely on window air conditioners plugged into old circuits during heat waves. Owners adding air conditioning or upgrading kitchens often need to upgrade unit panels and the building’s service.
Solar in LADWP territory
LADWP customers can install rooftop solar and batteries under the utility’s own interconnection rules, which differ from those of Southern California Edison. Systems need an LADBS permit and LADWP approval before they are switched on, and the utility may require a meter upgrade.
Typical timelines
Simple jobs like adding circuits or replacing devices can be scheduled quickly, but panel and service upgrades in Los Angeles depend on LADWP scheduling and can take weeks. Planning ahead avoids delays on renovation projects.
Panel brands flagged in LA
Home inspectors across Los Angeles flag older Zinsco and Federal Pacific panels, which many electricians recommend replacing.
