Rewiring a house typically costs between $3,000 and $20,000+, depending on the size of the home, labor rates, accessibility, and the condition of the existing electrical system. Most homeowners spend around $6,000 to $12,000 for a complete rewiring project.

Most electricians charge between $50 and $100 per hour, and total costs generally range from $2 to $10 per square foot.

If your home has outdated wiring, frequent breaker trips, flickering lights, or insufficient outlets, rewiring may be necessary to improve safety, efficiency, and code compliance.

What Is the Average Cost to Rewire a House?

The cost to rewire a house depends mainly on:

  • Square footage
  • Accessibility of walls and ceilings
  • Type of wiring being replaced
  • Electrical panel upgrades
  • Labor costs in your area

Here’s a general estimate:

Home Size Estimated Cost
Small Home (up to 1,500 sq. ft.) $3,000 – $6,000
Medium Home (1,500–3,000 sq. ft.) $6,000 – $12,000
Large Home (3,000+ sq. ft.) $12,000 – $20,000+

The final cost depends on how easily electricians can access the wiring behind walls, ceilings, and floors.

Cost to Rewire a House by Room

The cost to rewire a room depends on its size, electrical complexity, number of outlets and fixtures, and the type of appliances or equipment it supports.

Room Type Estimated Cost
Living Room $1,000 – $2,500
Kitchen $2,000 – $4,500
Bathroom $1,000 – $2,500

Actual rewiring costs may vary depending on your home’s layout, accessibility, local labor rates, and whether additional electrical upgrades are required.

Factors That Affect the Cost to Rewire a House

Several factors influence the overall rewiring cost.

  1. Home Size: Larger homes require more wiring, outlets, switches, and labor, increasing total costs.
  2. Accessibility of Wiring: Homes with accessible basements, attics, or crawl spaces are easier and cheaper to rewire.
  3. Electrical Panel Upgrades: Replacing an outdated panel increases project costs but improves electrical capacity and safety.
  4. Labor Costs: Electrician rates vary by location, experience, and project complexity.
  5. Age of the Home: Older homes often need additional upgrades due to outdated or unsafe wiring systems such as aluminum wiring.

Additional Costs to Consider

Beyond basic rewiring, homeowners may also pay for:

  1. Permits and Inspections: Usually cost between $200 and $1,000 depending on local building regulations.
  2. Drywall and Painting Repairs: Wall openings for wiring installation may require patching, repainting, or plaster repair.
  3. Smart Home Additions: Features like smart switches, EV charger wiring, USB outlets, and dedicated appliance circuits can increase total costs.
  4. Temporary Accommodation: Some homeowners choose to stay elsewhere during major rewiring projects.
  5. Electrical System Upgrades: Surge protection, grounding improvements, or new circuits may add extra expenses.

Signs Your House Needs Rewiring

Your home may need rewiring if you notice:

Homes older than 30–40 years should also be inspected for outdated electrical systems.

How Long Does It Take to Rewire a House?

A full house rewiring project usually takes between 3 and 10 days, depending on the size of the home, accessibility of the wiring, the number of electricians working on the project, and the amount of wall or drywall repair required. Larger or older homes with outdated wiring systems may take longer to complete.

Can You Live in a House While It’s Being Rewired?

Yes, you can usually live in a house while it is being rewired, but you should expect temporary power outages, dust, debris, noise, and limited access to certain rooms during the project. For larger rewiring jobs, some homeowners choose temporary accommodations for added comfort and safety.

Benefits of Rewiring Your Home

Rewiring your home not only improves electrical safety but also enhances performance, energy efficiency, and long-term property value.

  • Improved Safety: Modern wiring reduces the risk of electrical fires, short circuits, and overloaded circuits.
  • Better Electrical Performance: New wiring supports modern appliances, HVAC systems, home offices, and entertainment devices more efficiently.
  • Increased Home Value: Updated electrical systems can improve resale value and make your home more attractive to buyers.
  • Code Compliance: Rewiring helps ensure your home meets current electrical safety codes and standards.

Conclusion

Rewiring a house is a major investment, but it plays an important role in improving electrical safety, supporting modern power needs, and increasing long-term property value. While the cost to rewire a house can range from $3,000 to $20,000+ depending on the size and condition of the home, upgrading outdated wiring can help prevent electrical hazards and improve overall system performance.
