The cost to rewire a house typically runs anywhere from $3,000 for a small, easily accessible home to $30,000 or more for a large house with plaster walls and no attic or crawl space access, and most Ojai homeowners land somewhere in the $6,000 to $15,000 range for a full rewire.
Beyond the direct safety improvement, rewiring supports the electrical demand of modern life in a way older wiring simply wasn’t built for, from home offices running multiple devices at once to EV charging and smart home systems that didn’t exist when many Ojai homes were originally built.
What actually drives the cost of rewiring a house
Square footage matters, but it is not the biggest factor. How easily an electrician can reach the wiring behind your walls, floors, and ceilings has a much bigger impact on the final bill than the size of the home itself. A 2,500 square foot house with an open attic and a full basement can sometimes cost less to rewire than a 1,200 square foot bungalow with plaster walls, finished ceilings, and no crawl space at all. Cost guides from Angi put full-house rewiring at roughly $5 to $17 per square foot, with most projects on a 2,500 square foot home landing between $10,000 and $30,000 before permits and drywall repair are factored in.
Beyond accessibility, the other major cost drivers are the age and condition of the existing panel, whether the home has aluminum or knob-and-tube wiring that needs full removal rather than simple replacement, the number of circuits and outlets being added, and whether you plan to live in the home during the work or arrange temporary housing.
How long a full home rewire actually takes
Most full-house rewiring projects take between three and ten days of active electrical work, according to HomeGuide, with larger or older homes running toward the longer end of that range. That number covers the wiring itself, not the drywall patching, texture matching, and repainting that typically follow. Once you add finishing work back in, plan on the project taking closer to two weeks from start to a fully move-in-ready home, particularly if multiple trades need to coordinate on wall repair after the electrician closes everything up.
Living in the home during the rewire
It is usually possible to stay in the house while rewiring happens, but expect rolling power interruptions to individual circuits, dust from wall or ceiling openings, and limited access to certain rooms for a few days at a time. Homeowners doing a larger project, or one that touches most rooms in the house at once, often find it easier to arrange short-term housing for the most disruptive one or two days, then move back in for the remainder.
Signs your Ojai home may actually need a rewire
Frequent breaker trips, flickering or dimming lights when a major appliance kicks on, warm or discolored outlet covers, a persistent burning smell near outlets or the panel, and two-prong ungrounded outlets throughout the house are the most common indicators we see. Homes in Ojai built before the mid-1970s are the ones we most often find still running on some or all of their original wiring, and many of these houses have already had at least one appliance or lighting upgrade layered on top of wiring that was never designed for today’s electrical demand.
Experts generally recommend at least a partial rewire every 25 to 30 years, even though copper wiring installed correctly can technically last 50 to 70 years. The gap between what the wiring can physically survive and when it stops being adequate for modern households is where most rewiring decisions actually get made.
Full rewire versus a partial or room-by-room update
Not every home needs to be gutted and rewired from scratch. If an electrical inspection shows the wiring itself is in reasonably good condition but a specific area, such as a kitchen or an addition, needs more circuits or GFCI protection, a targeted update through our new circuit installation service may be enough. Rewiring room by room does tend to cost more in total than doing the whole house at once, since each visit carries its own setup, patching, and inspection overhead, but it spreads the expense out over time, which matters for homeowners tackling a larger remodel in phases.
A full house rewiring makes more sense when the existing wiring is aluminum, knob-and-tube, or otherwise failing in multiple areas, or when a major remodel already has walls open throughout the home.
“The quote almost never changes because of square footage. It changes once we’re inside the walls and see what we’re actually dealing with, whether that’s easy attic access or three layers of finished ceiling with no way in except cutting drywall.”

Older Ojai homes and aluminum or knob-and-tube wiring
A meaningful share of the older housing stock in Ojai still has some original wiring in place, and in homes from the 1960s and 1970s that sometimes means aluminum branch circuit wiring rather than copper. Aluminum wiring is not automatically dangerous, but it does require different connectors and more frequent inspection, since aluminum expands and contracts more than copper at connection points, which can loosen terminations over time and, left unchecked, create a real fire risk at outlets and switches rather than at the wire itself.
If an inspection turns up aluminum wiring, our aluminum wire replacement team can advise whether full replacement or a connector-based remediation is the right call for your specific circuits.
Homes old enough to still have knob-and-tube wiring, generally anything built before the 1950s, almost always need a full rewire rather than a partial fix, since knob-and-tube has no ground path and was never designed for the electrical load of a modern household.
What’s actually included in a professional rewiring quote
A rewiring quote is rarely just “wire and labor.” A complete quote should break out the cost of the wire itself, typically THHN copper in modern installations since it is more affordable than older wire types while still meeting current standards, along with new outlets, switches, and cover plates throughout the home. It should also account for the rough-in phase, where wire is run and boxes are set before anything is closed up, and the finish phase, where devices are installed and tested once walls are patched. Permit fees, which commonly run $250 to $900 depending on your jurisdiction, and an electrical inspection, typically $150 to $250, are separate line items that a thorough quote will list rather than bury into a single lump sum.
If your project also needs a new panel, that is usually quoted separately from the wiring itself, since panel capacity and branch circuit wiring are technically distinct scopes of work even though they are frequently done together. Ask any electrician you’re considering to itemize these pieces individually. A vague, single-number quote makes it much harder to compare bids or to understand which part of the project is driving the cost.
Code compliance beyond just replacing the wires
A rewire is also the natural point to bring a home up to current code in ways that have nothing to do with the wire itself. That includes adding GFCI protection everywhere current code requires it, adding AFCI protection in living areas as the modern code demands, and correcting any undersized or overcrowded outlet boxes uncovered along the way. Homeowners sometimes assume “rewiring” means only pulling new cable, but a rewire done to current code is really a full electrical system update, and skipping these secondary updates to save money usually just means paying for them separately, and less efficiently, later.
How to prepare your home before the crew arrives
Clearing furniture away from walls in rooms being worked on, protecting flooring in high-traffic areas, and having a plan for pets during the noisiest days all make the project go faster and with less cleanup. If you’re staying in the home, ask your electrician for a room-by-room schedule so you know which areas will lose power on which days, and plan around anything that needs continuous power, such as a home office setup or medical equipment. Homeowners who take a few minutes to walk the project scope with their electrician beforehand consistently report fewer surprises once the work actually starts.
Paying for a rewire: financing and insurance considerations
Rewiring is rarely an expense homeowners have budgeted for in advance, and it is worth knowing your options before committing to a quote. Home equity loans, dedicated home improvement loans, and in some cases contractor financing are the most common ways homeowners cover the cost. It is also worth checking your homeowner’s insurance policy, since some carriers will cover a portion of rewiring costs tied to a covered event, such as damage from a rodent infestation or a documented fire hazard finding, though routine modernization of old wiring is typically the homeowner’s responsibility.
Rewiring and home value in Ojai
Beyond safety, old or failing wiring is one of the more common findings in a pre-sale inspection, alongside missing GFCI protection and outdated panels. Buyers increasingly ask directly whether a home’s wiring has been updated, and an unaddressed knob-and-tube or aluminum wiring finding can slow a sale or lead to a price negotiation well beyond the actual cost of the fix. For homeowners planning to sell within the next few years, tackling a rewire proactively, rather than reactively during escrow, generally costs less and causes far less stress, since it removes the finding from the inspection report entirely rather than leaving it as a bargaining chip for the buyer.
It’s also worth noting that a documented, permitted rewire is a selling point in its own right for many buyers, particularly those who have been through the experience of discovering old wiring in a previous home. Keeping your permit and inspection paperwork after the project is complete gives future buyers, and your own insurance company, a clear record of the work.
Choosing the right electrician for a rewiring project
A full rewire is one of the larger electrical projects a homeowner will take on, so it’s worth being deliberate about who does the work. Ask for a license number and verify it’s current, ask whether the quote includes permit and inspection fees or treats them as separate line items, and ask how the electrician typically handles unexpected findings, such as discovering additional aluminum wiring or a damaged junction box mid-project. A contractor who can answer these questions clearly and walk your specific attic or crawl space before quoting is generally a better sign than one offering a number over the phone without ever seeing the house.
Getting an accurate quote for your home
Because accessibility drives cost more than square footage, the only way to get a truly accurate number is an in-person walkthrough where an electrician can check your attic, crawl space, and panel before quoting. Our electrical rewiring services team handles everything from a single-room update to a full whole-house rewire for homes across Ojai, and can tell you during that first visit whether your project realistically needs the whole house opened up or whether a more targeted approach will get you where you need to be.
If your rewiring project overlaps with a kitchen or bathroom remodel where plumbing lines are also being moved, our partners at plumbing near Ojai can coordinate that side of the work so both trades aren’t opening the same walls twice. And if you want a starting point before committing to anything, our team serving Ojai and the surrounding area can schedule a walkthrough and give you a real number based on your actual house, not a national average. That walkthrough typically takes less than an hour and gives you a far more useful starting point than any online calculator, since every one of those calculators is working from averages rather than what’s actually behind your specific walls.
