What Does It Cost to Rewire a House?

What Does It Cost to Rewire a House?

No two Los Angeles home rewiring projects cost the same. Whether you’re living in one of LA’s historic homes or a more modern space, rewiring is an important part of keeping your home safe and efficient. From materials to square footage, let’s break down the cost to rewire a house.

Factors That Affect the Cost to Rewire a Home

Many variables impact home rewiring cost, including size, materials, and more.

Size and layout of the house

The size, layout, and age of your home are major factors in rewiring needs. The larger and more complex a home is, the more labor and materials it’ll require — that includes multi-story homes and those with basements, attics, and crawl spaces as electricians must work through multiple levels.

More outlets and light switches also translate to more complex rewiring projects, and you can expect to spend $100 to $185 per outlet. You may also need three-prong, GFCI, and USB outlets. If your home still has knob and tube rewiring, it requires replacement for safety purposes.

Materials 

The type and amount of materials required affect the cost of rewiring a house. Some common wiring materials include:

  • THHN/THWN wire: Thermoplastic, highly heat-resistant, nylon-coated (THHN) and thermoplastic, heat-resistant, “wet”, and nylon-coated (THWN) wires average $0.84 per foot.
  • NM cable: Non-metallic (NM) wires average $0.56 per foot.
  • UF cable: Underground feeder (UF) cables suited for wet locations cost about $0.71 per foot.
  • Coaxial cable: Coaxial cables cost around $0.25 to $0.35 per linear foot and require specialized outlets.
  • Low-voltage wire: Wiring for thermostats, doorbells, and other low-voltage devices costs around $0.25 to $0.35 per foot.

Accessibility and ease of installation

Newer homes usually have layouts designed for easy access to wiring for electricians as per building regulations, but most older homes don’t usually make rewiring a simple task. The more work required to reach wires through plaster, brick, and studs, the more you can expect to pay in labor. 

Older properties also often have hidden challenges that require addressing. For example, in older homes with lath-and-plaster walls, wiring is more difficult to access as wall removal and repair can add days to a project. Keep in mind that repairing walls can account for up to 30% of the project cost.

Electrical panel upgrade

If your home hasn’t been renovated or upgraded since the 1950s or earlier, chances are your electrical panel isn’t up to code. Older 60-amp panels don’t meet modern electrical requirements and can present hazards to your home. Most homeowners opt for a 200-amp electrical panel upgrade, which can range between $400 and $2,500 for the unit and installation, to meet the safety and power needs of the modern home.

Average Cost Estimate for House Rewiring

In addition to the above cost factors, the scope of your home’s rewiring can affect the costs. See the difference in full home rewire costs vs. per area costs.

Full house rewire cost

Generally, rewiring a small home costs less than a large home. The average cost of electrical wiring installation is $8,500 — depending on size and other factors, costs can range from less than $1,000 to up to $30,000.

Per room or per square-foot cost

Rewiring a house generally costs $2 to $4 per square foot. The rooms involved in rewiring can also influence costs as some electrical codes require more or specialized outlets and circuits in certain areas.

See the following average rewiring costs based on square footage:

  • 1,000: $4,700
  • 1,500: $7,400
  • 2,000: $9,800
  • 2,500: $12,300
  • 3,000: $14,000

Additional Considerations

Include the following considerations in your rewiring plan as you organize your budget and logistics.

Local permits and inspections fees

Permits and inspections are necessary to protect your home and household from electrical hazardous. Rewiring, panel upgrades, and other electrical work require permits, and homeowners can face heavy fines and penalties besides safety risks if they fail to obtain one.

Santa Ana permit costs vary depending on the scope of work and other details. Standard and safety permits can range from $75 to $900. Inspections, whether for maintenance or rewiring purposes, range from $100 to $125.

Labor costs and contractor fees

Professional electricians charge between $50 and $100 per hour. You can hire more people to speed up the project. With rewiring projects typically requiring up to a week to complete, labor costs can range from $1,000 to $7,400. Preparing and cleaning up the worksite, such as moving furniture, protecting valuables, and other tasks, can take several days and likewise increase labor costs. 

DIY vs. Professional Rewiring

Rewiring a home is complex and hazardous, and only licensed electricians should perform this work. Attempting to do this work on your own, even with electrical know-how, can lead to much higher costs than professional installation due to potential mistakes and inadvertent damage and carries risk of significant injury.

Experienced electricians, however, possess the appropriate training, knowledge, and skills to complete your home’s rewiring safely, efficiently, and effectively. Choosing cost-friendly materials and handling non-electrical work during the process may help offset your costs. Making upgrades to your home’s rewiring can also improve its energy efficiency, saving on utility costs in the long-term.
