Electrical Wiring Services in Los Angeles
When a home inspector flags aging wiring, an insurance carrier demands documentation before renewing a policy, or a property manager discovers that a building’s electrical system was never designed to handle modern loads, the question is rarely whether wiring work is needed. It is who to trust with it. RG Electric is a licensed C10 electrical contractor, License #910807, serving homeowners, property managers, and building owners across Los Angeles. We handle residential rewires, new circuit installations, multi-unit wiring upgrades, ADU electrical scopes, and commercial wiring projects from permit application through city inspection and closeout.

Why Wiring Becomes a Problem in Older Los Angeles Properties
Los Angeles has one of the oldest housing stocks of any major American city. Neighborhoods like Silver Lake, Echo Park, Van Nuys, Encino, and Koreatown are filled with homes and apartment buildings constructed before the 1970s, many of which have never had their wiring updated. What was installed then was designed for a fraction of the electrical load that a modern household or commercial tenant now places on a system.
Knob-and-tube wiring, once standard in homes built before the 1940s, has no ground conductor and cannot safely support the three-prong devices, appliances, and grounded circuits that current code requires. Cloth-insulated wiring from the mid-century period becomes brittle and cracks over decades, exposing conductors inside walls. Aluminum branch circuit wiring installed during the 1960s and 1970s expands and contracts differently than the copper devices it connects to, creating loose terminations that arc and overheat over time.
Beyond age, the load profile of a typical LA property has changed dramatically. EV chargers, home offices, high-efficiency HVAC systems, and commercial kitchen equipment draw sustained current that older wiring was never rated to carry. Insurance carriers in California have responded by scrutinizing electrical systems more carefully at renewal, and home inspectors routinely flag legacy wiring conditions as material deficiencies during real estate transactions. The consequence is that wiring work is no longer something property owners can defer indefinitely.
Residential Rewiring and New Circuit Installations
RG Electric performs partial and full residential rewires throughout Los Angeles County. A partial rewire targets specific areas or circuits where wiring is deteriorated, undersized, or non-compliant, while leaving sound wiring in other parts of the home intact. A full rewire replaces all branch circuit wiring throughout the structure and is typically paired with a panel upgrade to ensure the new wiring connects to equipment sized to support it.
Our approach minimizes disruption wherever the structure allows. We map existing routes carefully, fish new cable through attics, crawlspaces, and wall cavities, and keep access openings small. Where drywall or plaster must be opened, we restore finishes neatly at project closeout. Common issues we address during residential rewiring include shared neutral conductors, ungrounded outlets throughout older rooms, undersized service entrances, and aluminum-to-copper transitions that require properly rated connectors.
New circuit installations are a frequent standalone request. Dedicated circuits for kitchen appliances, laundry rooms, home theaters, workshops, and high-amperage equipment like electric ranges, dryers, and tankless water heaters are all work we handle regularly. Each new circuit is permitted, inspected, and labeled before closeout.
Combining a Rewire with a Panel Upgrade
A rewiring project frequently uncovers a panel that is too small, too old, or a brand that insurance carriers have flagged as a condition of renewal. Zinsco, Federal Pacific, Challenger, and Pushmatic panels appear regularly in older Los Angeles homes and apartment buildings. These panels are known fire hazards, and insurance companies in California have been increasingly direct about requiring their replacement before issuing or renewing coverage.
Handling a rewire and a panel upgrade in Los Angeles under a single permit is more efficient than treating them as separate projects. It reduces the number of inspection visits, ensures the new wiring connects to equipment rated to carry it, and gives the property owner a complete documented upgrade rather than a patchwork of separate scopes. We plan and manage combined rewire and panel replacement projects regularly across residential and multi-unit properties.
Commercial and Multi-Unit Wiring in Los Angeles
Wiring work in apartment buildings, mixed-use properties, and commercial spaces involves constraints that residential projects do not. Occupied units require coordinated shutoff windows, advance notice to tenants, and sequenced work that keeps the building functional throughout the project. Load profiles are more complex, code requirements differ from residential standards, and documentation requirements are stricter when permits are pulled on commercial or multi-unit structures.
RG Electric works directly with property managers and building owners on multi-unit wiring upgrades across Los Angeles, from corridor lighting and laundry room circuits to parking structure wiring and gate access control power. Tenant improvement scopes, common area upgrades, and building system wiring are all work our team handles on schedule and with the permit documentation that commercial clients require. For a full overview of what we provide for apartment buildings and commercial properties, see our commercial electrical services in Los Angeles.
ADU and Garage Conversion Wiring
ADU construction has expanded steadily across Los Angeles as homeowners and investors add living units to existing properties in neighborhoods from Culver City to Sherman Oaks to Torrance. A new ADU requires its own electrical service or a properly designed subpanel, dedicated circuits for kitchen and laundry appliances, GFCI protection in all required locations, and in many cases an EV charging circuit as part of the Title 24 compliance package.
We handle ADU electrical scopes from load calculation through permit closeout, coordinating with general contractors or working directly with homeowners depending on the project structure. Garage conversions follow a similar scope and are a common request across the San Fernando Valley and Westside neighborhoods where older detached garages are being converted to living or workspace.
Warning Signs That Wiring Work Is Needed
These conditions in a home or building often point to underlying wiring issues worth addressing before they escalate into safety hazards or insurance complications.
- Lights flickering or dimming when appliances turn on
- Outlets or switch plates that feel warm to the touch
- Circuit breakers that trip repeatedly under normal loads
- Burning smells near outlets, switches, or the panel
- Two-prong ungrounded outlets throughout older rooms
- Discoloration or scorch marks around any electrical device
- An insurance carrier or home inspector has flagged the wiring in writing
Some of these symptoms are resolved with targeted repairs, dedicated circuit additions, or device replacements. Others indicate that the wiring itself has reached the end of its serviceable life and a broader scope is needed. A site evaluation by a licensed electrician is the only reliable way to determine which applies.
How RG Electric Handles Wiring Projects
Every wiring project follows the same structured process regardless of scope. We provide a detailed written estimate before any work begins, with no hidden fees and no surprises added at closeout. New work receives a free estimate. Diagnostic service calls for existing issues are charged a service fee upfront, which covers the electrician’s time to investigate and report findings.
Once a scope is approved, we pull required LADBS permits before work begins, protect floors and finishes during installation, torque all connections to specification, and test every circuit before leaving the property. We coordinate and attend the city inspection, update the panel directory, and provide labeled photos and permit documentation at project closeout. All workmanship is backed by a 12-month guarantee.
Frequently Asked Questions
Do I need a permit for wiring work in Los Angeles?
Yes, in most cases. New circuit installations, rewiring, and subpanel additions require permits and inspections from LADBS. We handle the permit application and attend the inspection on your behalf. You receive the closed permit and documentation at closeout.
How do I know if my home needs rewiring?
Common indicators include flickering lights, warm or discolored outlets, breakers that trip frequently, burning smells near the panel or devices, and ungrounded two-prong outlets throughout the home. Homes built before 1970 benefit from a wiring evaluation, particularly if the system has never been updated.
Can you rewire a home without opening all the walls?
In many cases, yes. We use fishing techniques through attics, crawlspaces, and existing conduit paths to minimize wall openings. Where access points are needed, we keep them small and restore finishes neatly. The extent of wall opening depends on the home’s construction and the scope of the rewire.
What is the difference between a partial and a full rewire?
A partial rewire addresses specific circuits or areas where wiring is deteriorated, undersized, or non-compliant, while leaving sound wiring in other areas intact. A full rewire replaces all branch circuit wiring throughout the structure. We recommend based on what the site evaluation reveals, not on a blanket scope.
Can wiring work be done in an occupied apartment building?
Yes, with proper planning. We sequence work by unit or zone, coordinate shutoff windows in advance, post notices for residents, and work off-hours when needed. Most multi-unit wiring projects are completed with minimal disruption to tenants.
Do you handle ADU wiring in Los Angeles?
Yes. ADU wiring is a significant part of our residential work across Los Angeles. We handle load calculations, subpanel design, dedicated circuits, GFCI requirements, and EV charging provisions as part of a complete ADU electrical scope, coordinated through a single permit where possible.
