Direct Answer For Owners (AEO)
Whole-house rewiring in Los Angeles runs $4,200 to $28,600 in 2026, with a typical 1,400-1,800 sq ft single-story rewire landing between $9,500 and $15,800 including permits and basic patching. The lower band covers small drywall-finished homes with accessible attic and crawlspace, simple circuit counts, and compatible existing panels. The upper band reflects multi-story homes with plaster walls, knob-and-tube remediation, panel upgrades, sub-panel additions, full AFCI/GFCI buildout, smoke and CO interconnect, and finish restoration. Square footage, wall finish, knob-and-tube presence, circuit count, and patch trade scope drive most of the cost. No direct utility rebates apply, but insurance-rate reductions on documented K&T remediation are often material.

Why The Price Band Has That Shape
A whole-house rewire sweeps from $4,200 to $28,600 because square footage, wall finish, and circuit count compound on each other. The bottom is a small single-story bungalow with accessible attic and crawlspace, drywall throughout, twelve circuits being replaced one-for-one, and a panel that already supports the load. The top is a three-story 1920s house with plaster walls and lath, no usable attic over the third floor, knob-and-tube remediation across forty-plus circuits, a panel upgrade, a sub-panel addition for an outbuilding, complete AFCI/GFCI buildout, low-voltage runs for smoke and CO interconnect, and the patch-and-paint trade that follows every fish.

Permit Cost And Inspection Timing
Rewires pull an electrical permit through LADBS that is priced by circuit count and ampere rating, with most whole-house rewires landing in the mid-hundreds for the permit fee but stretching across six to ten inspections (rough, insulation, drywall close, finish trim, fixture, special). Plan check is required on knob-and-tube remediation in many jurisdictions and on any service-upgrade-tied scope. Glendale, Burbank, and Pasadena route through their own electrical inspectors who have local preferences on AFCI brands, GFCI placement, and tamper-resistant receptacle requirements that the rewire plan must respect.

Labor Drivers That Inflate The Bid
Fishing wire through finished plaster is the rate-setter. A 1920s plaster-and-lath wall does not accept a stud-finder or a fish-tape the way drywall does, and every fish risks cracking the plaster face. Two-story routing through balloon-framed walls means firestopping at every level. Knob-and-tube circuits cannot be left energized in insulated cavities per code, so the rewire plan has to take whole branches out of service in sequence. Outlet box replacements that were nailed to lath in 1932 require new old-work boxes and a careful pull. Smoke and CO interconnect across multiple bedrooms is a low-voltage trade running in parallel.

Equipment And Material Tier Choices
Wire grade is largely standardized: 12 AWG copper Romex for 20A circuits, 14 AWG for 15A, 10 AWG for 30A dryer or AC circuits. Where the spec varies is in conduit-required locations (garages, basements, exteriors), in AFCI/GFCI breaker brand to match the panel, and in low-voltage cable categories for data, doorbell, and thermostat. Tamper-resistant receptacles are now code throughout living areas. Whole-house surge protection at the panel is required on rewires in California. Smoke and CO alarms with hardwired interconnect plus battery backup are part of the rewire scope, not a separate trade.

What Fast Quotes Hide
The patch-and-paint trade following the rewire is the largest hidden cost, and it is rarely owned by the electrician. Plaster patching to match texture is a specialty sub at a specialty rate. Trim removal and reinstallation around baseboards and casings is a finish-carpenter line. Knob-and-tube remediation reveals abandoned splices in attic insulation that require an insulation-removal sub and sometimes asbestos sampling. Old-work boxes that crumble when pulled need new boxes plus plaster repair. The homeowner's hotel or living-room-tent time during a multi-week rewire is real budget that does not appear on any bid.

Rewiring is not a utility-rebated scope on its own. LADWP, Glendale Water & Power, and Pasadena Water and Power do not pay for branch-circuit replacement. The federal IRA 25C credit covers electrical-panel work tied to electrification but does not cover the rewire itself. Where the dollars do show up is on insurance: a documented whole-house rewire with knob-and-tube remediation usually qualifies the home for standard insurance pricing rather than the surcharged or non-renewable tier that older systems trigger. That insurance delta is sometimes thousands of dollars per year and is the real financial argument for the work.

How To Read Three Estimates Side By Side
Read three rewire bids by their circuit count, their plaster-repair plan, and their inspection sequence. The honest bid lists every circuit by name (bedroom 1, kitchen small-appliance 1, kitchen small-appliance 2, dishwasher, disposal, etc.), separates knob-and-tube remediation from new-circuit run, names the AFCI/GFCI breaker brand, includes a patch-and-paint allowance with a square-foot estimate, and outlines the inspection holds. A bid that lists 'whole-house rewire — $14,000' as a single line is hiding the circuit count. The bid that walks the house with the homeowner and marks fishing routes on a floor plan is the bid that has worked in this kind of construction before.

I do not want a crew selling a part until the readings tell the same story twice. On rewiring, the expensive mistake is usually not the part itself. It is the missed condition around it.

Rewiring Cost Questions
What is the typical price range for rewiring in Los Angeles?
$4,200 to $28,600 for a standard rewiring project in the LA basin. The low end is a clean swap on accessible equipment; the high end is hillside access, equipment-tier upgrade, permit-plus-inspection scope, or finish protection.
What pushes rewiring cost toward the high end?
aluminum branch circuits, attic access, hillside or attic access, asbestos or plaster protection, code-triggered corrections (AFCI, GFCI, expansion tank, condensate neutralizer), and equipment-tier upgrades. Plan-check delays add schedule but not equipment cost.
Are permits and inspection included in this range?
Verdugo Houseworks includes a typical mechanical, plumbing, or electrical permit in the range, plus inspection coordination. Plan-check fees on larger scopes (panel upgrades over 200A, repiping with re-stack, sewer line repairs in city ROW) are billed at cost when they exceed the over-the-counter threshold.
What rebates apply to rewiring in Los Angeles?
Depending on scope: LADWP Home Energy Improvement, SCAQMD Clean Air, TECH Clean California for heat-pump water heaters, federal IRA 25C credit (up to $2,000 for qualified heat pumps), and GWP efficiency rebates on Glendale parcels. We document the model and AHRI/ENERGY STAR match the rebate program will require.
Why does rewiring cost vary so much by address?
Three drivers: access labor (hillside staging vs flat lot), code triggers (older 1920s wiring or gravity-furnace removals), and equipment tier. Two rewiring project jobs on the same street can sit 30% apart because one closet needs a aluminum branch circuits correction and the other does not.
How should I compare three rewiring estimates?
Compare line items, not totals. Does each estimate name model and serial, the readings logged, aluminum branch circuits, attic access, permit handling, and which work is excluded? A round number with no scope breakdown is not a real estimate.
Rewiring Cost Reviews
★★★★★
Our May 22, 2025 visit when the shutoff valve would not hold for ZIP 90042. As the mobile notary working from home, I needed panel upgrade notes that a landlord, inspector, or buyer could read later. Verdugo photographed a Moen shower valve, checked load calculation, and explained how grounding changed the scope in Mount Washington. Kept the drain line open through a 20 gallon flow test. The paperwork made the boundary between this scope and leak detection and rewiring clear enough for our file.
★★★★★
Our June 2, 2025 visit when the condo board asked for notes for ZIP 90039. As the tenant, I needed furnace installation notes that a landlord, inspector, or buyer could read later. Verdugo photographed a Bryant furnace, checked return air, and explained how venting changed the scope in Silver Lake. Balanced two bedrooms that were 4 degrees apart. The paperwork made the boundary between this scope and rewiring and ac installation clear enough for our file.
★★★★★
Our July 4, 2025 visit when the kitchen remodel exposed old pipe for a La Crescenta address with steep approaches, brush-clearance concerns, longer material runs, and jurisdiction checks before permits. Verdugo treated the job as furnace installation, not a generic service call, and checked gas line sizing, condensate routing, and a long line-set route. The scope gave us the number we needed before scheduling the repair. Found two open grounds before replacing outlets. Aram explained which reading mattered before the crew ordered parts. The crew explained where leak detection and rewiring might matter later and where it did not affect this visit.
★★★★★
Our July 16, 2025 visit when the sewer camera reached a root spot for a Highland Park address with steep hillside streets, narrow driveways, limited curb parking near York Boulevard, and older crawlspace openings. Verdugo treated the job as panel upgrade, not a generic service call, and checked utility disconnect, load calculation, and a mixed copper and PEX line. The scope gave us the number we needed before scheduling the repair. Reduced static pressure by 0.18 inches. The crew explained where rewiring and ac installation might matter later and where it did not affect this visit.
★★★★★
Our August 17, 2025 visit when the service entrance looked undersized near Frogtown. The Atwater Village house needed panel upgrade because a Generac transfer switch was no longer predictable under load. The technician wrote down breaker compatibility, meter main, the utility note for LADWP electric and water, SoCalGas natural gas, and the access concern before pricing. Kept the new shutoff reachable without moving shelves. The notes flagged leak detection and rewiring only as a related condition, not as work we had already approved.
★★★★★
Our August 30, 2025 visit when the dishwasher line leaked under tile near Sherman Oaks. The Studio City house needed furnace installation because a Siemens load center was no longer predictable under load. The technician wrote down AFUE match, gas line sizing, the utility note for LADWP electric and water, SoCalGas natural gas, and the access concern before pricing. Set the tankless flush plan at 12 month intervals. The notes flagged rewiring and ac installation only as a related condition, not as work we had already approved.
★★★★★
Our September 30, 2025 visit when the rental house lost cooling for ZIP 90041. As the winter visitor, I needed furnace installation notes that a landlord, inspector, or buyer could read later. Verdugo photographed a 100 amp panel, checked return air, and explained how venting changed the scope in Highland Park. Cut the nuisance trip from daily to zero over a week. The paperwork made the boundary between this scope and leak detection and rewiring clear enough for our file.
★★★★★
Our October 12, 2025 visit when the attic access looked tight for ZIP 90042. As the multi-unit owner, I needed panel upgrade notes that a landlord, inspector, or buyer could read later. Verdugo photographed a Lutron dimmer bank, checked grounding, and explained how breaker compatibility changed the scope in Eagle Rock. Documented 42 feet of branch wiring. The paperwork made the boundary between this scope and rewiring and ac installation clear enough for our file.
★★★★★
Our November 13, 2025 visit when a narrow side yard changed staging for a Silver Lake address with steep stair entries, permit parking, shared walls, and finished interiors that limit exploratory openings. Verdugo treated the job as panel upgrade, not a generic service call, and checked utility disconnect, load calculation, and a York condenser. The scope gave us the number we needed before scheduling the repair. Sealed a return leak that was pulling attic dust. The crew explained where leak detection and rewiring might matter later and where it did not affect this visit.
★★★★★
Our November 25, 2025 visit when the gas line size needed a second look for a Toluca Lake address with gated drives, narrow side yards, city-line jurisdiction checks, and tree roots near sewer laterals. Verdugo treated the job as furnace installation, not a generic service call, and checked condensate routing, return air, and an A.O. Smith tank. The scope gave us the number we needed before scheduling the repair. Kept the furnace vent slope within the listed range. The crew explained where rewiring and ac installation might matter later and where it did not affect this visit.
