How Much Does Whole House Rewiring Cost in California?
The national average for a full rewire in 2026 sits between $4,000 and $15,000 on a 1,500 to 2,000 square foot home with reasonably open walls, with larger or harder-to-access homes pushing closer to $25,000 or more. California prices follow the same shape but trend $2 to $3 per square foot higher than the national mean, because labor rates are higher and the older home stock in the Bay Area and along the Sacramento Valley typically requires more plaster work, more permit time, and tighter routing through finished walls.
For most San Jose and Chico homeowners, the realistic 2026 budget for a complete whole-house rewire is $5,000 on the low end (a small, accessible single-story home with an open attic) and $30,000 on the high end (a multi-story home with plaster walls, knob-and-tube wiring, and a panel that also needs to be replaced). Jackson Electric has been wiring California homes since 1981 and pulls every permit ourselves. We do not subcontract the route or hand off the inspection.
Whole House Rewiring Cost Per Square Foot in San Jose and Chico
Per-square-foot pricing is the cleanest way to budget a rewire because it scales with home size and labor accessibility. Below is the 2026 California band Jackson Electric sees in the two markets we serve. The Bay Area band reflects San Jose labor rates and the higher permit cadence in Santa Clara County. The North Valley band reflects Chico and the surrounding Butte County communities.
| Home Size | National Estimate ($2 to $6/sq ft) | San Jose Estimate ($5 to $9/sq ft) | Chico Estimate ($3 to $7/sq ft) |
|---|---|---|---|
| 1,000 sq ft | $2,000 to $6,000 | $5,000 to $9,000 | $3,000 to $7,000 |
| 1,500 sq ft | $3,000 to $9,000 | $7,500 to $13,500 | $4,500 to $10,500 |
| 2,000 sq ft | $4,000 to $12,000 | $10,000 to $18,000 | $6,000 to $14,000 |
| 2,500 sq ft | $5,000 to $15,000 | $12,500 to $22,500 | $7,500 to $17,500 |
| 3,000+ sq ft | $6,000 to $18,000 | $15,000 to $30,000+ | $9,000 to $22,000 |
Labor Band by Region
Labor accounts for 60 to 75 percent of a rewire bill. Licensed C-10 electricians in the Bay Area generally charge $95 to $135 per hour. Around Chico and the North Valley, the going rate is $75 to $105 per hour. A typical 1,800 square foot rewire runs 90 to 130 labor hours, which is where the bulk of the bill comes from. Material costs (copper NM cable, boxes, breakers, devices) scale with linear feet of cable, not square feet, but materials usually land in the $1,500 to $4,500 range for a single-family home.
Six Factors That Affect Your Rewiring Cost
Home Age and Construction
Homes built before 1970 often have plaster walls, fire-blocked stud bays, and irregular framing that slow cable routing. A 1950s rancher in San Jose with plaster runs 15 to 25 percent higher in labor than a similar-sized 1990s drywall home. Eichlers and other slab-on-grade builds add their own constraint because the floor is not a routing path, so all branch circuits run through walls and ceilings.
Wall Access and Crawlspace
An open attic or a tall crawlspace can drop the labor estimate by thousands. A tight crawlspace with low clearance or a finished basement without access points pushes it the other way. Most California single-stories let an electrician fish new wire with only a handful of small access cuts. Multi-story homes need more wall openings, which means more drywall or plaster repair.
Electrical Panel Condition
If your panel is 60 or 100 amps, has Federal Pacific or Zinsco breakers, or is full, a panel replacement needs to be bundled with the rewire. Plan for $1,500 to $4,500 for a 200-amp panel upgrade in California. See our electrical panel upgrade cost guide for the full breakdown.
Materials (Copper vs Older Wiring)
Modern copper NM-B cable is the standard for new branch circuits. If you have knob-and-tube or aluminum branch wiring, removal and abatement is its own line item, typically $3,000 to $8,000 on top of the rewire. Cloth-insulated NM cable from the 1950s through 1970s should also be replaced even when it is technically still working.
Number of Circuits and Outlets
A modern California rewire targets 18 to 28 branch circuits and brings outlet spacing up to current code (12 feet maximum between outlets on usable wall space, every kitchen and bath GFCI-protected, every bedroom AFCI-protected). Adding outlets during the rewire costs $100 to $200 per device installed and is much cheaper than retrofitting later.
Permits and Inspections
Every California whole-house rewire requires an electrical permit and one or more inspections. Permit fees plus rough-in and final inspections typically add $200 to $1,000 to the total. Jackson Electric pulls the permit, schedules every inspection, and walks the job with the inspector. We do not allow the homeowner to take on the permit risk.
Common Add-Ons and How They Change the Total
The base rewire price covers straight branch-circuit replacement. Most California homes need at least one of the upgrades below at the same time. Bundling them with the rewire is almost always cheaper than calling an electrician back later.
| Add-On | Typical CA Range | What It Covers |
|---|---|---|
| 200-amp panel upgrade | $1,500 to $4,500 | New panel, breakers, mast or meter base if needed |
| Subpanel install | $900 to $2,800 | Detached garage, addition, or ADU feed |
| Knob-and-tube removal | $3,000 to $8,000 | Old wiring disconnect plus disposal |
| Aluminum wire replacement | $3,500 to $9,000 | Branch circuit copper conversion |
| AFCI or GFCI protection upgrades | $125 to $250 per device | Bedroom AFCIs, kitchen and bath GFCIs |
| Hardwired smoke and CO detectors | $150 to $400 per unit | Interconnected, code-required where missing |
| Drywall or plaster patch | $4 to $8 per sq ft of repair area | Often subbed to a patch and paint crew |
Permits and Inspections in San Jose and Chico
In San Jose, an electrical permit for a whole-house rewire is pulled through the Santa Clara County Building Permit Counter or the City of San Jose Building Division depending on jurisdiction. Permit fees scale by valuation and typically land between $300 and $900 for a complete rewire. Most San Jose jobs require a rough-in inspection (before walls are closed back up) and a final inspection. Plan for one to two weeks between rough-in and final to allow patching and paint.
In Chico, the Butte County Department of Development Services or the City of Chico Building Division issues the permit. Fees in Butte County typically run lower than in Santa Clara County, often $200 to $600 for a single-family rewire. Inspection cadence is similar (rough-in then final). Jackson Electric has been pulling permits in both jurisdictions for decades and knows the local inspectors’ expectations on cable supports, box fill, and AFCI placement.
Signs Your House Needs Rewiring
If you are watching for symptoms before scheduling a rewire estimate, the most common are flickering or dimming lights when an appliance starts, breakers that trip with normal household loads, a faint scorched or burning smell near outlets or switches, two-prong outlets throughout the house, warm faceplates, or buzzing from a switch. Homes built before 1970 often still carry knob-and-tube, aluminum branch circuits, or ungrounded cloth-jacketed NM. Any of those is reason enough to schedule a rewire assessment. A panel that has Federal Pacific or Zinsco breakers should also trigger an inspection regardless of how the rest of the wiring looks.
Is It Worth Rewiring an Older Home?
Yes, in three common situations. First, when the existing wiring is a safety risk (knob-and-tube, aluminum branch, scorched outlets), rewiring is the only way to bring the home back to a modern safety standard. Second, when you are loading the home up for EV charging, heat pump HVAC, or induction cooking, the old panel and circuits will not keep up. Third, when you are planning to sell, a permitted rewire removes one of the largest line items a home inspector can flag and often makes an older home insurable again with carriers that decline knob-and-tube. The cost is meaningful, but the alternative (a fire risk plus a future deal-killer at closing) is more expensive.
How Long Does a Whole House Rewire Take?
Most California single-family rewires take five to ten working days from rough-in to final inspection, with two-story or plaster-wall homes pushing toward two to three weeks. Add a few days for drywall patch and paint after the final. You can usually stay in the home during the work, with power off in one zone at a time. Jackson Electric will sequence the cable runs so the kitchen and at least one bath stay live each evening unless the panel itself is being swapped.
How to Budget and Pay for the Work
Homeowners cover rewiring costs four ways, in roughly decreasing order of frequency. A home equity loan or HELOC offers the lowest rate for a project this size and treats it like the capital improvement it is. A home improvement personal loan works for homeowners without much equity yet, with slightly higher rates and no collateral risk. Cash and savings work cleanly on partial rewires or smaller homes. Local programs occasionally support rewiring when it is tied to electrification (a heat pump install, an EV charger install, an induction range), so check with PG&E and the California Energy Commission for current rebates. Jackson Electric does not finance the work directly. We give a free estimate, pull the permit, and the rest is your call.
Whole House Rewiring in San Jose
San Jose’s older neighborhoods (Willow Glen, Rose Garden, Naglee Park, parts of Cambrian) sit on housing stock from the 1940s through 1970s that often carries knob-and-tube or aluminum branch wiring. Eichler tract pockets along Trimble Road and in West San Jose add slab-on-grade routing constraints. A typical 1,800 square foot San Jose rewire lands $9,000 to $16,000 in 2026, with knob-and-tube removal or a 200-amp panel upgrade adding to the total. Jackson Electric has been pulling permits in Santa Clara County since the early 1990s. For a free San Jose rewire estimate, call (408) 266-5351 or visit our San Jose electrical services page.
Whole House Rewiring in Chico
Chico’s downtown core and the surrounding communities of Paradise, Oroville, and Magalia have homes from the 1920s onward, many of which still carry cloth-insulated or knob-and-tube wiring. Post-Camp Fire rebuilds in Paradise and Magalia generally arrive at our shop with modern wiring already in place, but the older Oroville and downtown Chico stock often needs a full rewire alongside a panel upgrade. A typical 1,600 square foot Chico rewire runs $7,000 to $12,000 in 2026. Jackson Electric runs a Chico office staffed with licensed California C-10 electricians.

Frequently Asked Questions About Whole House Rewiring Cost
How much does it cost to rewire a 1,500 square foot house?
A 1,500 square foot rewire runs about $3,000 to $9,000 nationally, $7,500 to $13,500 in San Jose, and $4,500 to $10,500 in Chico in 2026. The spread depends on wall access, age of the home, and whether the panel needs upgrading at the same time.
Does whole house rewiring include a panel upgrade?
Not by default. Most quotes price the rewire and the panel as two line items. If the panel is older than 25 years or undersized, plan for $1,500 to $4,500 in additional cost to bring it up to 200 amps.
How long does a whole house rewire take?
Five to ten working days for most California single-family homes, two to three weeks for larger or plaster-wall homes. Add a few days for drywall patch and paint after the final inspection.
Do I need a permit to rewire my house in San Jose or Chico?
Yes. Both Santa Clara County (San Jose) and Butte County (Chico) require an electrical permit for a whole-house rewire. Permits typically cost $200 to $900 depending on jurisdiction and valuation. Jackson Electric pulls every permit and schedules every inspection.
Can a house be rewired without removing drywall?
Often, yes. Electricians fish new cable through walls using small access points at outlets, switches, and junctions. Some drywall or plaster cuts are typically needed in finished homes, but full demolition is rare. Plaster homes require more cuts than drywall homes.
Is rewiring worth it before selling the house?
Almost always, if the wiring is outdated (knob-and-tube, aluminum branch) or the panel cannot pass inspection. Permitted rewires remove one of the largest negotiating points a buyer’s inspector flags and make the home insurable with carriers that otherwise decline outdated wiring.
How much does knob-and-tube removal add to a rewire?
Knob-and-tube removal adds $3,000 to $8,000 on top of the base rewire in California. The cost covers disconnecting the old runs, removing or abandoning porcelain knobs and tubes, and verifying nothing is left live in the walls.
Does insurance require updated wiring?
Many California carriers either decline or surcharge homes with knob-and-tube or aluminum branch wiring. A permitted rewire usually removes the surcharge and restores eligibility for standard policies. Confirm with your specific carrier before booking the work.
