Behind every outlet and light switch is a network of wiring that keeps your home powered, efficient, and safe. As technology evolves and power needs increase, so does the importance of having a modern electrical wiring system that can support your household.

Whether you’re starting new construction or bringing an older home up to code, understanding the full wiring cost is a key part of any renovation or building project. The cost to wire or cost to rewire can vary widely depending on your location, the size of your home, and the complexity of the system you need.

This guide will walk you through the typical cost to rewire a house and wire a new house in 2025 and provide the information you need to make smart, informed decisions.

Average Cost to Wire a House

The national average cost to wire a house ranges from $4 to $9 per square foot. This translates to approximately $6,000 to $22,500 for homes between 1,500 and 2,500 sq ft.

In other words, if you’re wondering how much does it cost to handle residential electrical work for a typical home, this is the basic estimated cost range most homeowners can expect to pay.

Cost Breakdown by Home Size

House Size (sq ft)	Average Cost Range
800	$2,400 – $4,000
1,000	$4,000 – $9,000
1,500	$6,000 – $13,500
2,000	$8,000 – $18,000
2,500	$10,000 – $22,500
3,000+	$12,000 – $27,000+

What’s Included in Basic Wiring Costs

The standard per square foot pricing typically includes:

• Electrical wiring materials (NM cable, commonly known as “Romex”)
• Junction boxes for outlets, switches, and fixtures
• Basic electrical outlets and switches
• Standard circuit breaker panel (100–200 amp electrical panel)
• Labor to install and pull each electrical line
• Basic permits and inspection fees

Most homeowners can expect their new wiring to last between 50 to 70 years if installed correctly and if it meets current building codes and the National Electrical Code.

New Construction vs. Rewiring Costs

There’s a significant cost difference between wiring a new construction home and choosing to rewire a house that already exists.

New Construction Wiring

Wiring a new house during initial residential construction typically costs $4 to $9 per square foot. This lower electrical cost per square foot reflects the ease of access during the building process when walls are open and there are no obstacles to running wire or installing conduit.

The new electrical process typically follows these stages:

• Planning the wiring system and electrical layout
• Rough-in phase (pulling wires through open wall framing)
• Installing junction boxes
• Final connections after drywall installation
• Installing fixtures, outlets, and switches

Rewiring Costs

To rewire a house (especially older ones) costs considerably more, ranging from $5 to $17 per square foot, depending on accessibility and the home’s age. This higher price point reflects several challenges:

• Removing old wiring and outdated existing wiring
• Accessing closed walls (often requiring cutting and patching drywall)
• Working around existing insulation and structures
• Additional labor hours for more complex installation costs
• Potential code updates and compliance requirements

Older homes often built in the early 1900s or mid-century with knob-and-tube or aluminum wiring typically could cost the most to rewire, with complete replacements ranging from $12,000 to $35,000 for average-sized homes. The average cost to rewire in these cases is much higher because the electrical system must be brought up to today’s safety standards and meets local codes.

Key Cost Factors

Several variables significantly impact the total cost of wiring a house or the cost to rewire your house.

Home Size and Layout

The size of your home and overall layout directly affects material and labor costs. Larger homes with more rooms require more wiring materials, junction boxes, and circuit runs. Homes with open floor plans typically require less wiring used than those with numerous small rooms and specialized spaces.

Number of Outlets, Switches, and Fixtures

The National Electrical Code (NEC) has specific requirements for outlet placement, including:

• One outlet at least every 12 feet of wall space
• Outlets within 6 feet of doorways
• GFCI outlets in wet locations (kitchens, bathroom, outdoors)

Each additional outlet or switch increases both material costs and labor to install. Premium fixtures and specialized outlets (like USB-enabled or smart outlets) further add to the wiring cost.

Type of Wiring

The most common type of wiring in homes includes:

• Copper wiring: The industry standard, offering excellent conductivity and durability.
• Aluminum wiring: Found in many homes built between 1965–1972, often requiring replacement for safety.
• Conduit: Required in certain applications, adding cost but improving protection and flexibility.

The choice of different wiring types, wiring materials, and ground wire requirements all affect the cost to wire throughout the house.

Labor Rates by Region

Electricians typically charge between $50 and $130 per hour, but rates can vary depending on location, complexity, and demand. Urban markets with higher living costs generally see higher labor costs than rural areas for the same residential electrical work.

Permit and Inspection Fees

Electrical permit fees typically range from $100 to $300 depending on your municipality and the local building department. Most projects require multiple inspections, including:

• Rough-in inspection (before walls are closed)
• Final inspection (after all fixtures are installed)

These fees are essential budget items that ensure your home meets local building codes and safety rules.

Room-by-Room Wiring Costs

Different rooms have varying electrical needs, which affects the wiring cost per room.

Kitchen

Average cost: $470 to $1,710 for a 151 sq. ft. kitchen

The kitchen often has the most complex electrical needs due to:

• Multiple dedicated circuit runs for major appliance loads
• GFCI protection for all countertop outlets
• Specialized lighting (under-cabinet, pendant, recessed)
• Higher amperage requirements for refrigerators, dishwashers, and ranges

Because of these demands, the electrical cost per kitchen can be higher than other spaces in the house.

Bathroom

Average cost: $300 to $1,300 per bathroom

Bathroom wiring costs reflect specialized wiring system requirements:

• GFCI protection for all outlets
• Dedicated circuit for hair dryers or heaters
• Ventilation fan wiring
• Water-resistant fixture and lighting

Despite their small size, bathrooms pack in a lot of code requirements, which affects the cost.

Living Areas and Bedrooms

Average cost: $350 to $1,500 per room (depending on size)

Living rooms and bedrooms generally require:

• Standard outlets along walls
• Ceiling fixtures or fan rough-ins
• One or more circuit runs per room

Homes with home offices, media centers, or extra new outlets will see an increased wiring cost in these areas.

Garage and Outdoor Spaces

Average cost: $1,000 to $4,000 for a standard two-car garage

Garages and outdoor spaces often involve:

• Weather-resistant electrical outlets and fixture choices
• GFCI protection for all outdoor circuits
• Power line runs to detached buildings
• Underground line installation in conduit

Running power to detached structures may cost $10 to $25 per linear foot, depending on distance from the main electrical panel and terrain.

Additional Features That Impact Cost

Modern homes often include specialized residential electrical features that increase the total cost of wiring a house.

Smart Home Systems

Smart systems require new wiring or additional low-voltage lines for controls, sensors, and hubs. This adds to installation costs and may require extra junction boxes, circuit space, or power supplies throughout the house.

Solar Panel Integration

Preparing your electrical system for solar sometimes means updating the electrical panel, adding breakers, and running conduit and power line connections—each of which raises the wiring cost.

EV Chargers and Generators

Adding a Level 2 EV charger or standby generator often means installing one or more dedicated circuits, upgrading to a 100-amp or larger electrical panel, and coordinating with electrical contractors for safe, code-compliant installation.

DIY vs. Hiring a Licensed Electrician

While some minor projects are DIY-friendly, full-scale wiring a house or choosing to rewire a house should almost always be handled by a licensed electrician.

The Cost of Professional Installation

A licensed electrician ensures that:

• All wiring used meets national electrical code and local building codes
• The electrical system supports increased power demands from modern appliance loads
• Each circuit breaker and electrical panel is sized correctly

For a complete home wiring project, labor costs generally make up 40–60% of the total cost.

Safety and Legal Considerations

DIY electrical work can violate building codes, fail inspection, and put your home at risk. The benefits of hiring pros include:

• Work using proper wiring materials and conduit
• A system that meets local codes
• Fewer surprises when you sell the house or request an insurance claim

Because residential electrical work is so critical to safety, this is not an area where you want to cut corners.

Tips to Save on Electrical Wiring Costs

Even though the cost to rewire your house or wire a new house can be high, there are ways to manage expenses.

Bundle Projects

Combining a kitchen remodel, bathroom upgrade, and rewire work lets the electrician run wires while walls are already open, reducing labor costs and installation costs.

Get Multiple Quotes

Electrical contractors may give very different cost estimate numbers for the same residential electrical job. Because bids can vary depending on workload and sourcing, it’s smart to get at least three quotes and compare the estimated cost and scope, not just the bottom line.

Plan Ahead

Using a simple cost calculator, mapping circuits per room, and planning for future electrical needs (like EV chargers or new outlets) can reduce mid-project changes that drive up wiring cost.
