If you own an older home in Indianapolis or anywhere across Central Indiana, you have probably wondered at some point whether the wiring inside your walls is still safe. The short answer for most pre-1980s homes is: it may not be. The longer answer is that the cost to rewire a house in Indianapolis depends on several specific factors, and knowing those factors upfront helps you plan, budget, and make the right call for your family.
We are Zimmerman Electric, a family-owned electrical contractor serving Marion, Hamilton, Hendricks, Boone, Johnson, Morgan, Shelby, and Hancock counties. We have rewired hundreds of homes across the Indianapolis metro area, from 1920s bungalows in Irvington to 1970s ranches in Speedway and mid-century colonials in Broad Ripple. This guide is built on that direct field experience, and every number in it reflects what we actually quote and complete in the Central Indiana market today.
Whole house rewiring in Indianapolis typically costs between $8,000 and $20,000, with most 1,500 to 2,500 square foot homes landing in the $10,000 to $15,000 range. The table below breaks down typical estimates by home size and scope of work:
|
Home Size |
Partial Rewire Est. |
Full Rewire Est. |
Common Property Type |
|
Under 1,000 sq ft |
$5,000 to $9,000 |
$7,000 to $12,000 |
Older bungalows, small ranches |
|
1,000 to 1,500 sq ft |
$7,000 to $12,000 |
$10,000 to $16,000 |

$10,000 to $15,000 |
$13,000 to $20,000 |
Most Indianapolis suburban homes |
|
2,500 to 3,500 sq ft |
$14,000 to $18,000 |
$17,000 to $25,000 |
Larger suburban & newer builds |
|
3,500+ sq ft |
$18,000 to $25,000+ |
$22,000 to $35,000+ |
Large estates, custom homes |
These figures reflect 2026 Central Indiana market rates and include materials, labor, and stanAZZdard permit fees. They do not include panel upgrades unless noted. If your home also needs a panel upgrade alongside rewiring, add an additional $1,500 to $3,500 to your project estimate.
A free, no-pressure estimate from Zimmerman Electric is the most reliable way to get a number specific to your home. We assess your home in person before quoting, because two houses with identical square footage can have very different wiring situations behind the walls.

One of the most common questions we hear is: how much does it cost to rewire a house per square foot? It is a reasonable way to frame the question, but the honest answer is that per-square-foot pricing is a starting point, not a precise number.
In the Indianapolis market, electrical rewiring typically runs between $3.50 and $8.00 per square foot for a full rewire, depending on complexity. Here is how those ranges tend to break down:
Per-square-foot figures should always be treated as rough benchmarks. The actual cost of your rewiring project will depend on your home's specific construction, the condition of the existing wiring, and whether your electrical panel can support the new system.
No two rewiring projects are identical. These are the variables that most directly influence your final project cost:
|
Cost Factor |
What It Means for Your Project |
|
Home Size |
Larger homes require more wire, more circuits, and more labor hours |
|
Wiring Type |
Knob-and-tube or aluminum wiring adds complexity and disposal costs |
|
Panel Condition |
If the panel also needs upgrading, add $1,500 to $3,500 to the total |
|
Number of Rooms |
More rooms and circuits = higher total cost |
|
Accessibility |
Finished walls, crawlspaces, and tight attics increase labor time |
|
Outlet Count |
More outlets, switches, and fixtures mean more material and labor |
|
Permit Fees |
Indiana permit fees vary by municipality, typically $150 to $500 |
|
Occupied/Vacant |
Rewiring an occupied home requires additional care and staging |
The bigger the home, the more wire, conduit, outlets, switches, and labor hours are required. A 1,000 square foot bungalow has far fewer circuits than a 3,000 square foot two-story. We calculate circuit counts during our in-home assessment to give you an accurate quote before work begins.
Homes with knob-and-tube or aluminum wiring are more expensive to rewire because the old wiring must be carefully removed or de-energized, the replacement wire routed through existing cavities, and the disposal handled properly. Cloth-insulated wire from the 1940s through 1960s also adds cost due to its brittle condition and the care required to remove it without disturbing finished walls.
If your electrical panel is undersized, outdated, or using Federal Pacific Stab-Lok or Zinsco breakers, it will need to be replaced or upgraded as part of the rewiring process. Our electrical panel upgrade services handle both the panel replacement and the rewire coordination so the project stays on one timeline with one crew.
Rewiring a home with unfinished walls or an open basement is significantly faster and cheaper than rewiring a fully finished home with drywall, plaster, tile, or paneling. In finished homes, electricians must fish wire through walls, which requires more time and skill. Some drywall patching may also be necessary, which adds to the overall project cost.
A partial rewire addresses specific circuits, rooms, or sections of a home where the wiring is compromised or outdated. A full rewire replaces all wiring throughout the entire home, from the panel to every outlet, switch, light fixture, and appliance circuit.
We always give our honest recommendation during the estimate visit. If a partial rewire genuinely solves your problem, that is what we will tell you. We do not recommend a full rewire when a targeted fix will do the job.
The Indianapolis housing stock is a mix of eras. Older neighborhoods like Meridian-Kessler, Irvington, Fountain Square, and SoBro have substantial numbers of pre-1950 homes. Many of these still carry original wiring systems that pose real safety and insurance risks. Here is what we find most often:
|

Knob-and-tube wiring was standard in homes built before 1940. It uses ceramic knobs and tubes to route uninsulated wire through framing members. The core problems with knob-and-tube are that it has no ground wire, its cloth insulation becomes brittle and cracks over time, and it was never designed to carry the electrical loads that modern households demand.
|
SAFETY NOTICE: Knob-and-tube wiring cannot safely power modern appliances, EV chargers, or high-draw equipment. Many Indiana insurance carriers will not insure a home with active knob-and-tube wiring, or will charge significantly higher premiums. |
Aluminum wiring was commonly installed in homes built between the mid-1960s and early 1980s as a cost-saving measure during copper price spikes. The problem is that aluminum expands and contracts more than copper with temperature changes, causing connections to loosen over time. Loose aluminum connections create heat, and heat creates fire risk.
Not all aluminum wiring requires full replacement. In some cases, licensed electricians can install AlumiConn connectors or CO/ALR-rated outlets at each connection point as a cost-effective remediation. However, this approach requires a thorough inspection first. We assess the extent and condition of aluminum wiring before recommending the most practical solution for your home.
Yes. Electrical rewiring requires permits in all municipalities across Central Indiana, including Indianapolis and Marion County, Hamilton County, Hendricks County, and the surrounding counties we serve. This is not a formality. Permitted work is inspected by the local authority having jurisdiction (AHJ), which means your rewiring is verified to meet current Indiana Electrical Code before the walls are closed.
Unpermitted electrical work creates serious problems: it can void your homeowners insurance, create liability if a fire occurs, and complicate or derail a home sale. We handle the entire permit and inspection process on your behalf. You will never have to navigate a municipal building department or schedule an inspection yourself.
Permit fees in the Indianapolis area typically range from $150 to $500 depending on the municipality and the scope of work. These fees are included in our estimates so there are no surprise charges later.
Yes, in most cases. We plan rewiring projects in sections so that portions of the home remain powered while other areas are being worked on. This staged approach means your family can continue using the kitchen, bathrooms, and main living areas throughout most of the project.
There will be periods of a few hours where sections of the home are without power as we transition circuits. We communicate the daily schedule clearly at the start of each project day so you know what to expect. For full rewires on larger homes, some homeowners prefer to arrange temporary accommodations for the heaviest work days, but it is rarely a requirement.
For a typical 1,500 to 2,500 square foot Indianapolis home, a full rewire takes 3 to 5 working days. Smaller homes with straightforward construction may be completed in 2 to 3 days. Larger homes, historic properties, or heavily finished interiors can extend the timeline to 5 to 10 days.
The final inspection by the Indianapolis or county building department adds an additional scheduling step after the work is complete. We schedule this on your behalf, and it typically occurs within 3 to 7 business days of project completion depending on the municipality's inspection schedule.
Yes, and the ROI can be significant. Homes with updated electrical wiring are easier to insure, command higher appraisal values, and sell faster. Many home inspectors flag outdated wiring as a material defect, which forces sellers into price negotiations or costly last-minute repairs at closing.
Updated wiring also enables modern upgrades that add their own value: EV charger installation, smart home systems, high-amperage kitchen appliances, and home office power. A home with a fully updated 200-amp service and modern wiring throughout is a fundamentally better-positioned asset in the Indianapolis real estate market than one with 1950s knob-and-tube.
Many of our customers rewire their homes in conjunction with EV charger installation or whole-house surge protection, turning a single project into a complete electrical system upgrade.
Standard homeowners insurance policies in Indiana do not typically cover the cost of rewiring as a home improvement or preventive upgrade. However, there are two important exceptions worth understanding.
First, if a covered peril, such as a fire or storm, damages your wiring, the repair or replacement may be covered depending on your policy. Second, and more commonly relevant to Indianapolis homeowners, many insurance carriers will either require wiring upgrades as a condition of coverage renewal or will offer premium discounts after old wiring is replaced.
We recommend contacting your insurance carrier before your rewiring project begins. Some carriers will want to see the completed permit and inspection documentation before updating your policy. We provide all required documentation as a standard part of every project close-out.
Not every home announces its electrical problems loudly. Here are the most common warning signs we see in Central Indiana homes that need rewiring attention:
If several of these apply to your home, the investment in a proper wiring assessment is well worth the peace of mind. We offer free in-home electrical assessments with no commitment required.
While this guide focuses on residential rewiring, we also handle commercial electrical services in Indianapolis and Central Indiana. Commercial rewiring involves three-phase systems, higher amperage services, code compliance for commercial occupancy, and coordination with building inspectors and property management. If you own a commercial building with aging wiring, the same urgency applies, and the cost structure follows similar logic scaled to commercial square footage and load requirements
Rewiring is one of the most significant electrical projects a homeowner can undertake. The quality of the work, the accuracy of the permits, and the skill of the crew matter enormously to the long-term safety of your home. Here is what to look for when evaluating electricians for a rewiring project in Indianapolis:
