Aging cloth-insulated wiring, ungrounded outlets, and outdated circuits are hidden fire hazards lurking in many Southern California homes. Whole-house rewiring eliminates these risks while preparing your home for modern demands like rooftop solar, EV chargers, and smart appliances. The cost of electrical rewiring in Los Angeles varies based on home size and wall accessibility. In this updated 2025 guide, Farashi Electric outlines the key warning signs, provides real-world cost insights, and offers a step-by-step plan to help you upgrade your home’s wiring safely and efficiently.

 
Ten Red Flags You Need Electrical Rewiring
SymptomWhat It Means
Frequent breaker trips when the AC and microwave run togetherCircuits overloaded
Two-prong (ungrounded) outletsNo safe path for fault current
Warm or sizzling wall platesLoose connections causing arcing
Flickering lights during appliance start-upVoltage drop from undersized conductors
Cloth or knob-and-tube wiring visible in atticInsulation at end of service life
Aluminum wiring spliced with copperHigh-resistance joints
No GFCI/AFCI protection in kitchens & bedroomsCode non-compliance
Burnt smell near outletsInsulation breakdown
Outlets spark when you plug in devicesInternal arcing
You’re planning a major remodel or electrical panel upgrade in Los AngelesBest 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

  1. Wall Access – Open-stud remodel vs. finished plaster can double labor.
  2. Service Upgrade Required? – Adding a 200-amp panel adds.
  3. Low-Voltage Wiring Bundles
  4. Permit & Inspection
  5. Finishes – Patching lath-and-plaster walls is labor-intensive.

Hidden Savings

  • Home-insurance premiums drop 4-6 % for homes rewired within 25 years (State Farm 2024 survey).
  • Eligible for federal 25 C energy-efficiency tax credit when paired with heat-pump upgrade.
  • Bundling landscape lighting in Los Angeles adds less than 10 % to total labor but boosts curb appeal dramatically.

Our Rewiring Process (Clean, Documented, Inspection-Ready)

  1. Assessment & Load Check – Map circuits, evaluate panel capacity, identify safety/code gaps.
  2. Permit & Planning – Scope, circuit map, device counts, arc-fault/GFCI strategy, and schedule.
  3. Rough-In – New homeruns, AFCI/GFCI protection, grounding/bonding corrections, box sizing, and labeling.
  4. Device & Trim – TR outlets/switches, updated plates, neat panel schedules; torque to spec.
  5. Testing – Polarity, continuity, GFCI/AFCI trip-tests, insulation checks, and load verification.
  6. Inspection & Final – AHJ walkthrough; deliver photo log + permit close-out.

Timelines & Pricing 

Timelines & Pricing (Scope-Dependent)
Small room-by-room rewiring often completes in a few days; whole-home projects vary by square footage, access, and finish work. Final pricing depends on device counts, AFCI/GFCI, panel capacity upgrades, and patch/paint scope. We provide a written, permit-ready estimate after assessment.

Choosing the Right Materials & Add-Ons

Copper vs. Aluminum

While aluminum meets code, Farashi Electric specifies 12 AWG copper for branch circuits—40 % better conductivity and fewer loose-lug callbacks.

Aluminum & Knob-and-Tube: What We Do

We evaluate aluminum branch circuits for heat-related failures and use listed remediation (e.g., AlumiConn/COPALUM) or full rewiring as appropriate. For knob-and-tube, we replace brittle runs, add grounding, and bring outlets to modern safety (AFCI/GFCI where required), keeping finishes neat.

Low-Voltage Wiring
  • Cat-6 data runs for streaming & work-from-home.
  • Coax RG-6 for 4K video distribution.
  • 18/2 landscape lighting spurs to garden boxes—bundled now to avoid trenching later.

Code & Safety Essentials 

  • AFCI & GFCI: Bedrooms/living areas commonly require AFCI; kitchens, bathrooms, garages, outdoor and laundry areas need GFCI (local adoption applies).
  • Tamper-Resistant Outlets: Use TR receptacles in dwelling areas for child safety.
  • Grounding & Bonding: Correct equipment grounding and bonding (water/gas, metal raceways) are verified and upgraded where needed.
  • Labeling & Torque: Breakers/neutral/ground bars are labeled, and all terminations are torqued to manufacturer spec.
  • Box Fill & Cable Protection: Boxes sized per box-fill rules; cables protected at entries and along framing.

Permits & Local Rules (Los Angeles)

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 scope (service changes, multi-unit, structural impacts) may need plan review. We confirm your Authority Having Jurisdiction (AHJ), pull the permit, and schedule inspection before energizing.

Outdated wires are not just inconvenient—they’re a leading cause of hidden attic fires.
