Our licensed C-10 #910807 electricians prioritize safety, clean installation practices, and long-term durability, while handling permits, inspections, and documentation from start to finish.
Why Proper Electrical Wiring Matters in Your Home or Building
Electrical wiring forms the hidden network that powers everything in your property. Each circuit creates a complete loop: power flows from the breaker through the hot conductor to your devices or appliances, then safely returns via the neutral wire. A separate equipment grounding conductor provides a low-resistance path for fault current, allowing breakers or GFCIs to trip quickly and prevent shocks or fires.
When wiring is correctly sized, securely terminated, and protected in approved cable or conduit, your system operates efficiently and safely. Poor wiring, loose connections, overloaded circuits, deteriorated insulation, or improper grounding, leads to symptoms like flickering lights, warm outlets, frequent breaker trips, voltage drops, and increased fire risk. In Los Angeles, where many homes and apartment buildings date back decades and now support high-demand devices like EV chargers, home offices, and smart systems, updating wiring is often essential for both safety and performance.
Wiring Services for Los Angeles Homes and Properties
RG Electric provides full-spectrum wiring services for residential, multi-unit, and commercial properties throughout LA County. We specialize in new circuit installations, extensions, partial and complete rewires, and code corrections. Common residential and ADU projects include:
- Dedicated circuits for kitchens, laundry rooms, home theaters, and workshops

- Subpanel installations for ADUs, garages, or additions
- Whole-home surge protection integration
- Data and low-voltage wiring for networks, security systems, and smart home setups
We use quality materials, route cables neatly, secure them properly, and label every circuit and junction box for future reference. Homeowners and property managers receive detailed photos and documentation at project closeout.
Safe Rewiring for Older Los Angeles Homes
Many Los Angeles neighborhoods, from Silver Lake and Echo Park to the older residential streets of Van Nuys and Encino, feature homes built before the 1970s with wiring systems that were never designed for modern electrical loads. Knob-and-tube wiring, cloth-insulated conductors, and aluminum branch circuits can become brittle over time, fail under sustained load, or fall out of compliance with current NEC standards.
Minimally invasive rewiring approach
Our team performs minimally invasive rewires wherever the structure allows. We carefully map existing routes, fish new Romex or MC cable through walls and attics, avoid unnecessary demolition, and restore drywall or plaster neatly when access points are required. We address common legacy issues including shared neutrals, ungrounded outlets, undersized service entrances, and aluminum-to-copper transitions that need properly rated connections.
Pairing rewiring with a panel upgrade
A rewiring project frequently surfaces a panel that is too small, too old, or a legacy brand flagged by insurers. Combining a rewire with an electrical panel upgrade under a single permit is more efficient than handling them as two separate projects and ensures the new wiring connects to equipment sized to support it. We plan these combined scopes regularly and manage the permit coordination end to end.
Commercial and Multi-Unit Wiring in Los Angeles
Commercial and multi-unit properties have wiring demands that go beyond what a residential rewire involves. Apartment buildings in Koreatown, mixed-use properties along the Wilshire corridor, warehouses in the San Fernando Valley, and office buildings throughout West Los Angeles all present different load profiles, occupancy constraints, and code requirements that shape how wiring work gets planned and executed.
Tenant improvement wiring
Tenant improvements frequently require new dedicated circuits, updated lighting layouts, and dedicated power for equipment that the previous tenant never needed. We work with property managers and general contractors to deliver tenant improvement electrical scopes on schedule, with clean labeling and documentation ready for turnover. Off-hours scheduling is available when work cannot happen during normal business hours without disrupting existing occupants.
Common area and building system wiring
Corridor lighting, parking structure circuits, gate and access control power, booster pump rooms, and laundry room circuits are all wiring scopes that property managers encounter regularly. These circuits are often the first to show age in older buildings and the last to get attention until something fails. We assess, repair, and upgrade common area wiring with minimal disruption to building operations and residents. For the full scope of what we provide for commercial and multi-unit properties, see our commercial electrical services in Los Angeles.
ADU and garage conversion wiring
ADU construction is widespread 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 required locations, and often an EV charging circuit as part of the Title 24 compliance package. We handle ADU electrical scopes from load calculation through permit closeout.
Specialized Wiring for Pools, Spas, and Outdoor Features
Outdoor electrical installations require extra precautions due to moisture, UV exposure, and physical damage risks. For pools, spas, fountains, and landscape systems, we install proper equipotential bonding grids, GFCI-protected circuits, weatherproof enclosures, and correctly sized feeders. We bury conduit at code depth, use direct-burial cable where appropriate, and ensure all equipment meets Los Angeles swimming pool electrical requirements. Combine these circuits with professional outdoor lighting for enhanced safety and usability around patios, walkways, and entries.
Signs You May Need Wiring Repairs or Upgrades
These symptoms often point to underlying wiring issues that are worth addressing before they escalate.
- Lights flickering or dimming when appliances turn on
- Warm, discolored, or buzzing outlets and switches
- Frequent circuit breaker trips or blown fuses
- Burning smells or scorch marks near devices or the panel
- Power tools losing speed or electronics resetting unexpectedly under load
- Two-prong ungrounded outlets in older rooms
These problems are often resolved by load balancing, dedicated circuit additions, conductor repairs, or device replacements. Persistent panel overheating or repeated breaker failures may indicate the panel itself needs replacement rather than just the circuits. A panel evaluation can determine whether a service upgrade is the right next step.
Our Wiring Process
- Initial consultation — Send photos of your panel with the door open, any subpanels, and the areas where work is needed. We discuss your requirements and provide a detailed written estimate.
- Planning and permitting — We design the optimal routing, select appropriate materials for the application and environment, and pull required LADBS permits before work begins.
- Installation — Our crew protects floors and finishes, installs wiring to code standards, torques all connections to specification, and tests every circuit before we leave.
- Inspection and closeout — We coordinate and attend the city inspection, update your panel directory, and provide labeled photos plus documentation at project closeout.
Costs and Timelines
Costs vary based on run length, accessibility through attic or crawlspace versus finished walls, conduit requirements, any drywall patching needed, and whether panel work is part of the scope. A simple dedicated circuit addition often completes in one day. A partial rewire covering specific areas of a home typically runs two to three days. Full-home or building rewires span longer depending on size, finish level, and how much the structure allows for fishing wire without opening walls.
For the most accurate quote, include approximate distances, desired device locations, appliance specifications, and photos of existing conditions when you reach out. This lets us prepare before the site visit and give you a more precise range upfront.

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 in particular benefit from a wiring evaluation, especially if they have 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 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 of the building intact. A full rewire replaces all branch circuit wiring throughout the structure. We recommend based on what the inspection 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.
