Aging cloth-insulated wiring, ungrounded outlets, and outdated circuits are hidden fire risks found in many older Southern California homes. Whole-home rewiring helps eliminate these hazards while preparing your property for modern electrical demands such as rooftop solar, EV chargers, and smart appliances. The cost of electrical rewiring in Los Angeles depends on home size, layout, and wall accessibility. In this updated 2025 guide, Farashi Electric explains key warning signs, shares real-world cost insights, and outlines a clear step-by-step approach to upgrading your home’s electrical system safely and efficiently.
Audio transcript & key points
Wiring and rewiring ensures your home’s electrical system is safe, reliable, and ready for modern loads like HVAC upgrades, remodels, and new appliances. Common signs you may need rewiring include frequent breaker trips, flickering or dimming lights, warm outlets or switches, buzzing sounds, burning smells, outlets that stop working, or older wiring that no longer meets today’s safety expectations. A professional rewiring job starts with an on-site assessment and planning, then installs code-compliant wiring and properly sized circuits, confirms grounding, and fully tests the system before finishing. When needed, work can be staged to reduce disruption. Farashi Electric provides wiring and rewiring in Los Angeles with safety-first, neat workmanship and clear communication. Call (267) 248-5496 for a free estimate, and share photos of your electrical panel and the areas you’re upgrading for a quick pre-assessment.

For home rewiring in Los Angeles, CA, we help homeowners decide whether they need targeted circuit repairs, partial rewiring, or full home rewiring. Our residential electrical rewiring services include safe circuit planning, grounding and protection upgrades, reduction of hidden fire risks, and preparation for modern electrical loads like HVAC systems, EV charging, kitchen appliances, and smart devices.
If you’re already noticing flickering lights, warm outlets, or frequent breaker trips, our Electrical Problems in House – Los Angeles safety guide explains these symptoms, why they happen, and when it’s time to move from “monitoring the issue” to planning a full or partial rewiring.
| Symptom | What It Means |
| Frequent breaker trips when the AC and microwave run together | Circuits overloaded |
| Two-prong (ungrounded) outlets | No safe path for fault current |
| Warm or sizzling wall plates | Loose connections causing arcing |
| Flickering lights during appliance start-up | Voltage drop from undersized conductors |
| Cloth or knob-and-tube wiring visible in attic | Insulation at end of service life |
| Aluminum wiring spliced with copper | High-resistance joints |
| No GFCI/AFCI protection in kitchens & bedrooms | Code non-compliance |
| Burnt smell near outlets | Insulation breakdown |
| Outlets spark when you plug in devices | Internal arcing |
| You’re planning a major remodel or electrical panel upgrade in Los Angeles | Best time to run new cable |
Safety tip: If your home still uses 60-amp service, combine rewiring with a panel upgrade for maximum value.
Key Cost Drivers
- Wall Access – Open-stud remodel vs. finished plaster can significantly impact labor costs. If you want to keep drywall damage minimal, our guide on how to rewire a house without opening the walls explains the “surgical” methods we use in Los Angeles homes to fish new cables through small, postcard-sized openings instead of full demolition.
- Service Upgrade Required? – Upgrading to a 200-amp panel can increase overall project cost.
- Low-voltage wiring bundles (included in total scope where applicable)
- Permits & inspections required by local code
- Finishes – Patching lath-and-plaster walls can be labor-intensive and may affect final cost.
Our Rewiring Process
- Assessment & Load Check – Mapping circuits, evaluating panel capacity, and identifying safety and code compliance gaps.
- Permit & Planning – Defining scope, creating circuit maps, counting devices, setting arc-fault/GFCI strategy, and scheduling work.
- Rough-In – Installing new homeruns, adding AFCI/GFCI protection, correcting grounding and bonding, sizing boxes properly, and labeling circuits.
- Device & Trim – Installing TR outlets and switches, updating plates, organizing clean panel schedules, and torquing connections to spec. If you’re curious what safe, code-compliant fixture work looks like at the room level, our How to Wire a Light guide explains a typical light-circuit upgrade using the same safety standards we apply in full rewiring projects.
- Testing – Checking polarity and continuity, performing GFCI/AFCI trip tests, insulation resistance checks, and load verification.

Timelines & Pricing
Timelines & Pricing (Scope-Dependent) Small room-by-room rewiring typically completes in a few days, while whole-home projects vary based on square footage, accessibility, and finish work. Final pricing depends on device counts, AFCI/GFCI requirements, panel capacity upgrades, and patching/painting scope. We provide a written, permit-ready estimate after assessment. For a detailed breakdown of real LA projects, including what can extend timelines (plaster walls, panel upgrades, EV charging, remediation work), see How Long Does It Take to Rewire a House? before planning your project timeline.
Choosing the Right Materials & Add-Ons
Copper vs. Aluminum:
We commonly recommend copper branch-circuit wiring for residential rewiring because it is durable, widely accepted by inspectors, and well-suited for modern household electrical loads when properly sized. Most rewires also include replacing worn-out receptacles and adding new outlets where needed. If you’d like to understand safe outlet terminations, spacing, and GFCI/AFCI protection, our electrical outlet wiring in Los Angeles guide explains it step by step.
Aluminum & Knob-and-Tube: What We Do
We evaluate aluminum branch circuits for heat-related issues and apply listed remediation methods (such as AlumiConn/COPALUM) or full rewiring when appropriate. For knob-and-tube systems, we replace brittle wiring, add proper grounding, and upgrade outlets to modern safety standards (including AFCI/GFCI where required), while keeping finishes clean and consistent.
Code & Safety Essentials
AFCI & GFCI: Bedrooms and living areas commonly require AFCI protection, while kitchens, bathrooms, garages, outdoor, and laundry areas require GFCI protection (local code adoption applies).
Tamper-Resistant Outlets: TR receptacles are used in all dwelling areas for child safety.
Grounding & Bonding: Proper equipment grounding and bonding (including water/gas bonding and metal raceways) are verified and upgraded where needed. Labeling &
Torque: Breakers, neutrals, and ground bars are clearly labeled, and all terminations are torqued to manufacturer specifications. Box Fill & Cable
Protection: Boxes are sized according to box-fill requirements, and cables are protected at entry points and along framing.
Want a bigger-picture look at how all this wiring work ties into whole-home protection? Our electrical home safety in Los Angeles guide explains what a proper safety inspection covers, safe DIY pre-checks you can do, and how rewiring fits into a long-term plan to reduce risk—not just pass inspection once.
Permits & Local Rules
In the City of Los Angeles (LADBS) and LA County, electrical work typically requires a permit and final inspection. Straightforward residential rewiring often goes through express/online permitting, while larger scopes (such as service changes, multi-unit work, or structural impacts) may require plan review. We confirm your Authority Having Jurisdiction (AHJ), pull the permit, and schedule inspection before energizing the system.
