What a Licensed General Contractor Does for a Los Angeles Rewiring Project
Whole home rewiring is the complete replacement of a home’s electrical wiring, from the service entrance and main panel through every branch circuit, outlet, and switch in the building. For a Los Angeles homeowner, this project is managed by a licensed general contractor who coordinates the electrical scope, the LADBS permit, the inspection process, and the drywall restoration under one contract. Research from the U.S. Consumer Product Safety Commission found that homes with aluminum wiring manufactured before 1972 are 55 times more likely to have connections reach fire hazard conditions than homes wired with copper. In a city where a significant share of the housing stock predates 1970, that statistic is not abstract.
Wise Choice Remodeling manages rewiring projects across Los Angeles as the licensed general contractor and single point of accountability. The homeowner signs one contract, works with one project manager, and receives one 2-year workmanship warranty covering the full scope of electrical and restoration work.
Why Los Angeles Homes Need a Different Rewiring Approach
The wiring conditions inside a Los Angeles home depend almost entirely on when and where it was built. Highland Park and the Eastside are dense with Craftsman bungalows from the 1900s through the 1920s, many still running on original knob-and-tube. These homes have raised pier-and-post foundations, which gives crawl space access but also means wiring routes that were never designed for modern loads. Decades of settling in these century-old frames often leave junction boxes tilted, connections loosened, and splices buried under later work that was never permitted.
Across the Valley, the pattern shifts. Encino, Sherman Oaks, Tarzana, and Woodland Hills are dominated by postwar ranch homes from the 1950s and 1960s. These homes were built on slab-on-grade foundations with no crawl space access, which means rewiring requires attic routes or selective wall openings. Many of these homes had their original cloth-insulated copper partially replaced with aluminum branch circuit wiring during expansions in the late 1960s, creating a mixed system that is difficult to diagnose without opening walls.
Silver Lake and Los Feliz add another layer. Mid-century modern hillside homes by Neutra, Schindler, and their contemporaries sit on steep lots with limited exterior access. Panels are often tucked into garages at the low end of the slope, and running new circuits up through multi-level construction on a hillside is a different engineering exercise than rewiring a flat-lot ranch. The Spanish Revival homes near the Silver Lake flats and across Hancock Park and Mid-Wilshire carry their own challenges: plaster-and-lath walls over original cloth wiring, and many of these properties sit inside Historic Preservation Overlay Zones where even the location of a new meter base can trigger additional review.
Knob-and-Tube: The Oldest Active Wiring in the City
Knob-and-tube wiring was standard in Los Angeles homes built before the late 1940s. It uses single-insulated copper conductors strung between ceramic knobs and run through ceramic tubes where they pass through framing members. When it was installed, it was safe and code-compliant. The problem today is that it is ungrounded, it was never designed for the amperage modern appliances draw, and in many homes it has been modified by decades of unpermitted work. Insurance carriers across California are increasingly declining renewal on homes where knob-and-tube remains active. A homeowner whose carrier sends a non-renewal notice has a short window to address the wiring before coverage lapses.
There is a second, practical problem. Active knob-and-tube wiring cannot legally be buried under insulation. A homeowner in Highland Park or Angelino Heights who wants to upgrade attic or wall insulation to meet current Title 24 requirements must remove the knob-and-tube first. The rewire unlocks the insulation upgrade, and doing both together avoids opening the same walls and ceilings twice.
Aluminum Branch Wiring: The Valley’s Hidden Risk
Aluminum branch circuit wiring was installed in roughly 1.5 million American homes built between 1965 and 1973, when copper prices spiked. In the San Fernando Valley, where tract development boomed in exactly that era, aluminum wiring is common. The risk is not the aluminum itself but how it behaves at connections. Aluminum expands and contracts more than copper with temperature changes, loosening connections at outlets and switches over time. Those loose connections generate heat that builds gradually, sometimes over years, before causing a failure. By the time the homeowner notices a warm outlet or a faint burning smell, the damage behind the wall may already be significant.
Services Wise Choice Provides for Los Angeles Rewiring Projects
Every rewiring project is scoped to the specific conditions in the home. The scope may include any combination of the following, depending on what the on-site assessment reveals.
Full Knob-and-Tube Replacement
All active knob-and-tube circuits are replaced with modern copper wiring, new grounded outlets, and AFCI/GFCI-protected circuits as required by current California Electrical Code. The old wiring is either removed where accessible or properly abandoned and disconnected at the panel.
Aluminum Branch Circuit Replacement
All single-strand aluminum branch circuits are replaced with copper. Every connection point, from the panel through each outlet, switch, and junction box, is rebuilt to eliminate the expansion-related failure points that aluminum creates over time.
Electrical Panel Upgrade
Most older Los Angeles homes have 100-amp panels, and some pre-war homes still have 60-amp fuse boxes. A panel upgrade to 200 amps provides capacity for central air conditioning, an EV charger, a tankless water heater, and a modern kitchen with dedicated appliance circuits. The panel upgrade is typically done as part of the rewire to avoid a separate permit and a second disruption.
Dedicated Circuit Installation
High-draw appliances need their own circuits. A whole home rewire is the opportunity to add dedicated circuits for the HVAC system, laundry, home office, kitchen appliances, EV charger, and any future loads the homeowner anticipates.
Drywall Restoration
Wise Choice includes drywall patching and finishing in the rewiring project scope. The homeowner does not need to hire a separate contractor to close and finish the access points after the electrical work is complete.
How Wise Choice Manages a Los Angeles Rewiring Project
The process starts with an on-site estimate visit. A project manager inspects the existing panel, identifies the wiring type throughout the home, checks attic and crawl space access routes, and documents the current circuit layout and any visible code violations. The visit takes 60 to 90 minutes for a typical single-family home. The homeowner receives a written estimate that covers the full scope, materials, timeline, and permit costs.
Once the homeowner approves the scope, Wise Choice files the LADBS electrical permit. Straightforward residential rewires in the City of Los Angeles typically move through express or counter plan check permitting. Larger projects that include a service upgrade or involve structural access may go through standard plan review, which carries a 15 to 25 business day initial review period with potential correction cycles adding time. Homes in HPOZ districts such as Highland Park, Hancock Park, South Carthay, or Angelino Heights may need a Certificate of Appropriateness from the Office of Historic Resources before LADBS accepts the permit application, if any exterior-visible changes are part of the scope.
During construction, circuits are replaced section by section so the home retains partial power throughout the project. The rough-in inspection is scheduled with LADBS after new wiring is in place but before walls are closed. Once rough-in passes, drywall is repaired and finished. The panel is connected, every circuit is tested and labeled, and the final LADBS inspection is scheduled. Call (818) 483-8055 or schedule your estimate online to start the process.
LADBS Permits and California Code Requirements for Rewiring
Inside the City of Los Angeles limits, LADBS is the permit authority for all residential electrical work. A whole home rewire requires an electrical permit regardless of scope. The permit application specifies the address, scope of work, and contractor license information. Wise Choice files the permit, coordinates the rough-in and final inspections, and addresses any correction notices that arise during the process.
Current California Electrical Code requires AFCI protection on circuits serving bedrooms, living rooms, dining rooms, hallways, and closets. GFCI protection is required in kitchens, bathrooms, laundry areas, garages, unfinished basements, and outdoor areas. When a home is fully rewired, every circuit must meet these requirements regardless of what was in place before. All new wiring must be copper, properly sized for the circuit load, and installed in accordance with current code for box fill, grounding, and bonding.
Hillside properties in neighborhoods like Silver Lake, Hollywood Hills, Mt. Washington, and Eagle Rock may require additional review if the rewiring scope involves any grading or exterior conduit routing in areas designated as Very High Fire Hazard Severity Zones.
Los Angeles Neighborhoods Wise Choice Serves for Rewiring
The rewiring needs across Los Angeles break down largely by era and construction type. Across the Eastside, Highland Park, Eagle Rock, Echo Park, Atwater Village, and Los Feliz hold the city’s densest concentration of pre-war homes with active knob-and-tube. These neighborhoods also overlap with several of the city’s 35 Historic Preservation Overlay Zones, which can add a Certificate of Appropriateness step to the permit timeline for any work affecting the exterior.
In the Valley, Encino, Sherman Oaks, Studio City, North Hollywood, Van Nuys, Reseda, Tarzana, and Woodland Hills are built almost entirely from 1950s and 1960s tract homes. These are the neighborhoods where aluminum branch wiring, undersized panels, and slab-on-grade construction create the most common rewiring scenarios Wise Choice encounters. The flat rooflines and accessible attics on most Valley ranch homes make rewiring routes more straightforward than hillside construction, but the slab foundations mean there is no crawl space access and all low runs require wall openings.
Mid-City neighborhoods including Hancock Park, Koreatown, Mid-Wilshire, Miracle Mile, Fairfax, and West Adams carry a mix of Spanish Colonial Revival and Art Deco homes from the 1920s through the 1940s. These homes often have plaster-and-lath walls that require more careful cutting and patching than drywall. The HOA density in these areas and the HPOZ designations covering Hancock Park, South Carthay, and several other enclaves mean that the permit and approval process may involve more steps than in non-designated neighborhoods. On the Westside, Mar Vista, Palms, Westchester, and Playa del Rey hold a mix of postwar bungalows and mid-century homes with similar wiring conditions to the Valley stock.
