Your home’s wiring is integral to the way that you live in your home. While you may not see the wires hidden inside your walls and ceilings, they are delivering electricity to your lights, power strips, chargers, and appliances.

When building a new home or addition, you need electrical wiring installed in the process. Homes built before 1960 may not have the capacity to handle modern appliances. Some older homes may also have older wires that are corroding and causing issues that could be dangerous. When these problems occur, rewiring or replacing the wiring along with the outlets, switches, panel, and most fixtures is often required.

Because there are many types of wiring jobs, there is a wide range of associated costs. The national average range to wire a new home is between $4,000 and $10,000. The average homeowner pays $8,000 for new wiring, panel, outlets, and switches installed in a 2,000 sq.ft. home. This project’s low cost is $1,500 for new wiring in a 500 sq.ft. addition, while the high cost is $30,000 for rewiring an older home with hard-to-access wires, a panel upgrade, and updated fixtures, outlets, switches, heavy cabling, and jacks.

Electrical Wiring Cost by Type

Electrical wiring is running wires or cables to areas of the home. This is done through the walls and usually includes ensuring the various components and connections are in place for use, such as outlets, switches, and panels. This process is easier in new construction because it is done before the walls are finished. This makes the process easier and keeps costs down.

Rewiring happens in a home with old wires that no longer work safely. It is more labor-intensive because older wires must be removed first.


Cost of New Construction Wiring and House Rewiring

Cost of New Construction Wiring and House Rewiring


TypeAverage Costs per Square Foot (Installed)
New Construction$3 - $5
House Rewiring$6 - $10

Electrical Wiring Cost for a New House

Electrical wiring in a new house costs between $3 and $5 a square foot on average. Wiring for new construction is considerably easier than older homes. The wiring goes in before the walls so that the process is easier and less labor-intensive. In most cases, new wiring includes roughing in the wires, installing things like outlets, panels, and switches, and setting up for fixtures and lights. It can also include the wiring for ethernet cables and other “heavy” wiring. Wiring for a new house is always unique to the home and homeowner’s needs, so it varies in overall costs.

Electrical Rough-in Cost

Roughing in the electricity costs between $2 and $4 a square foot. This is adding the wiring but not finishing it. The wires are capped where outlets, light fixtures, and appliances are later installed. In most cases, the rough-in cost is not broken out of the total wiring cost, meaning you still pay the $3 to $5 a square foot total because the walls can be finished once the rough-in is complete. Then, the electrician returns to finish the wiring job. This completes the job, so the costs are usually priced together even though they are done in two stages.

Cost to Wire a Basement

The average cost to wire a basement is between $2 and $5 a square foot. Like sheds, basements can be given varying degrees of finish work. The NEC does not have minimum height requirements to install outlets in a basement; however, it is required that all those are GFCI outlets. You may only need light fixtures, or you may have large appliances installed. If you plan on finishing the basement, your costs are the same as in new home construction - everything is roughed, the walls are finished, and the finish work begins. So, your costs are the same as any new construction space if you add outlets, lights, and other features. If you already have rudimentary wiring, your costs could be lower.

Average Cost to Rewire a House

The average cost to rewire a house is between $6 and $10 a square foot. In rewiring, all the current wires are removed and replaced with new wires. In this case, small openings may need to be made in walls, ceilings, attics, or crawl spaces to pull the old wires out. New wires are threaded through, so this process is longer, more labor-intensive, and more costly than wiring a new home. If the areas being rewired are difficult to reach, the drywall may need to be removed. If this is the case, expect additional costs for new drywall installation and finish work.

Cost to Rewire a House by Location

Many times you may only need to rewire a single room. This can have a range of costs, depending on the layout’s complexity and whether you are remodeling that room. When the walls of the room are open during a full remodel, the cost to rewire is closer to the costs of installing new wiring. Your costs are higher if you are not remodeling, depending on how hard the wires are to access.

The costs below assume the average-size square footage for each area and range from rewiring during a remodel to rewiring in difficult-to-access areas.


Cost to Rewire a Kitchen, Garage and Room

Cost to Rewire a Kitchen, Garage and Room


LocationAverage Costs (Installed)
Kitchen$453 - $1,510
Garage$1,152 - $2,360
Room$1,443 - $4,810


Kitchen Rewire Cost

The average cost to rewire a kitchen ranges from $453 to $1,510. This assumes an average kitchen size of 151 sq.ft. Kitchens larger or smaller than this size may have different costs. These costs range from the wiring during a remodel to updated wiring with the kitchen intact. They include the complete replacement of wires with wiring updates for the fixtures and appliances. If you have more appliances than average or have higher-than-average electrical needs, your costs can be higher.

Cost to Rewire a Garage

The average cost to rewire a garage is $1,152 to $2,360. This cost assumes an average garage, but larger or smaller garages may have different costs. Most garages being rewired are not typically finished. Therefore, costs for rewriting a garage are often lower than rewiring a similarly sized room in the home’s interior. Costs include the complete replacement of all wires, outlets, and switches. If you have fixtures or appliances in the garage that need replacing, the wiring is included in the cost.

Cost to Rewire a Room

The cost to rewire the average room in a home is between $1,443 and $4,810. The average size of a room within a home is roughly 481 sq.ft. When rewiring a much larger or smaller room, your costs may be higher or lower. These costs involve the complete removal and replacement of the room’s wires. If you are remodeling and the walls are open, your costs are lower. If the walls are not open, your costs are higher.

Electrical Wiring Cost by Type of System

While many types of electrical systems have been developed over the years, only two are typically used in residential settings - lead sheathed and conduit. Many homes may need a combination, depending on the home’s layout and where the wires are installed. It is not uncommon to be given one bill rather than breaking apart the related costs. They are typically priced about the same, with similar cost ranges for installation, depending on the area and wire placement.


Cost of Lead Sheathed and Conduit Wiring Systems

Cost of Lead Sheathed and Conduit Wiring Systems


Type of Wiring SystemAverage Costs per Square Foot (Installed)
Lead Sheathed$3 - $5
Conduit$3 - $5


Lead Sheathed Wiring

Lead sheathed wiring costs between $3 and $5 a square foot. This wiring protects the cables from moisture, such as cables in kitchens and bathrooms. It uses conductors covered with a lead/aluminum alloy sheath that contains 95% lead. Not all electrical installations in kitchens and bathrooms require this wiring, however. In many instances, conduit wiring can protect the wires from moisture, if the wiring is run through PVC pipe. In some cases, conduit wiring makes use of holes cut through studs in the walls, which leaves the wires exposed. This means that lead sheathing may be a good choice for high-moisture areas if you are wiring an older home or area without much wall space to run a PVC conduit.

Conduit Wiring

Conduit wiring ranges from $3 to $5 a square foot. This is the most common wiring in residential buildings. It comes in two forms - concealed and surface. PVC or GI conduits are placed on the walls or roof, and the cables are run through the conduits. In concealed conduit wiring, the conduits are hidden inside wall slots, and the cables are run through them. This method is considered stronger and more aesthetically pleasing because you cannot see the wires. The conduit wiring used in your home varies on accessibility, the home’s age, and the amount of space you have in your walls and ceilings.

Electric Wire Price by Material

More than 20 cable types are used in residential buildings, but not all are common or something used in every home. Wires are made of copper or aluminum and may be insulated or sheathed in various materials, such as PVC. Each wire may be hot, grounded, or neutral, depending on its purpose. In most cases, the wiring cost is included in the labor cost.

Multi-Conductor Cable

Multi-conductor cable costs between $0.20 and $0.35 a linear foot. This cable is very common in some parts of the home. It features more than one conductor, but each is separately insulated. This is the cable for a security system as part of your home’s wiring. This cable could be used for video recorders and other audiovisual work. In some cases, it could be used as part of a home’s entertainment setup.

Shielded Twisted Pair Cable

The cost of a shielded twisted pair cable is $0.20 to $0.35 a linear foot. This material is used for video equipment. It is a pair of twisted wires, fairly inexpensive, and can be used for telephones, security cameras, and gaming equipment. With fewer homes having landlines and more security cameras becoming wireless, this cable is becoming less common. It is more commonly found in older homes.

Coaxial Cable Cost

Coaxial cables range from $0.25 to $0.35 a linear foot. This is a double-insulated cable with an inner tube and outer insulator. Coaxial cables are used for TVs and video equipment. This is the cable you install for most paid TV programming and some internet types. These are becoming less common as smart homes and different viewing systems emerge. You are more likely to find this cable in older homes.

Direct Buried Cable

Direct buried cable averages $0.40 to $0.50 a linear foot. This is a special uninsulated coaxial cable meant to be buried underground. It is good for high-speed transmissions. If you have cable or internet brought into your home, this is likely what is used. By being buried underground, it makes the cables less prone to issues with storms and interruptions. You likely cannot see this cable inside your home.

Metallic Sheathed Cable

Metallic sheathed cable costs between $0.50 and $0.70 a linear foot. These are sometimes known as BX or AC cables. They can be used in high-stress areas and use three plain stranded copper wires with PVC bedding and sheathing. These cables are not used as frequently as newer non-metallic sheathed cable. However, they can be used in interior and exterior applications. They can also be installed and used in a wide range of areas and are easy to work with for the electrician.

Underground Feeder Cable

Underground feeder cables range from $0.50 to $0.70 a linear foot. These are waterproof cables made of many wires grouped and embedded in plastic. They are typically used for applications like outdoor lighting. They are designed to run from your circuit breaker out of the house. By running underground, they are not seen and do not interfere with landscaping. They are also protected underground so that they can last longer with fewer complications.

Twin-Lead Cable

Twin-lead cables average $0.60 to $0.80 a linear foot. This is a relatively old cable that is not used much today. It was originally used for transmissions, such as TV and radio. The cable is a flat two-wire cable, with the wires contained inside a single sheath. It is most often used and requested by homeowners who are doing hobby wiring themselves. You are unlikely to have this wiring installed as part of a home wiring project.

Non-Metallic Sheathed Cable

Non-metallic sheathed cable costs between $0.60 and $0.80 a linear foot. These are flexible plastic-jacketed cables that contain 2 to 4 wires and a ground wire. They were made to replace the older metallic sheathed cables. They can be used nearly anywhere inside the house and take on many jobs. Many electricians prefer to work with these, but a few prefer the cheaper and older metallic sheathed cable. Both can update older wiring.

Ribbon Cable

Ribbon cable ranges from $1.50 to $2 a linear foot. These are flat and very low-voltage cables made of parallel wires. The wires are not used for connecting your home to your power supply but are more often for personal use. They are most commonly used for computer equipment. They may connect computers, printers, and other office equipment.

Cost to Rewire a House From Aluminum to Copper

If your home was built or last wired before 1960, you likey have aluminum wiring. Aluminum is lighter and less expensive than copper, so it had a brief period of being the preferred wiring material. Unfortunately, aluminum can expand and melt nearby surface materials when hot. It also corrodes over time and is not nearly as strong as copper. This makes it unsafe and more likely to catch fire, particularly if you attempt to upgrade to the additional amps needed to handle today’s heavier power loads. In fact, a CPSC research states that homes with aluminum wiring are 55 times more likely to suffer from fire damage and catch fire than copper wiring.

The cost of replacing aluminum wire with copper wire is between $6 and $10 a square foot, including materials and labor. This also includes a new circuit breaker, outlets, switches, and other necessary wiring. Your costs vary depending on how accessible the wire is and how easily the new wire can be installed.


Talk to local pros to get quotes for your electrical wiring

Parts of the House Wiring

The wires are only one part of the system that provides electricity and powers your lights and appliances. You also have other components to consider. In most instances, your home wiring includes everything, from the circuit panel to the outlets, switches, lights, and wiring for appliances. In most cases, the cost to wire a home includes most of these parts. Some of them may be installed by your electrical company, others are pieces of the wiring installation and serve no use to your electricity. Some have separate costs, such as if you have a new outlet installed in an existing home with current wiring. Others are only used as part of the initial wiring installation.


Wiring Home Circuit Panel, Electrical Tail, Main Earth, Conduits, Electrical Outlet...

Wiring Home Circuit Panel, Electrical Tail, Main Earth, Conduits, Electrical Outlet...


Circuit Panel

Homes built after 1960 have a circuit panel installed. This is made up of switches that connect or break the current to various rooms. The switches are designed to disconnect in a power overload. Circuit panels have replaced fuse boxes as the method of controlling for power overloads. If your home currently has a fuse box, upgrading your wiring means upgrading to a circuit panel. You may still need an upgrade if you already have a panel, depending on its age and size. Most of today’s modern homes have electrical needs that outweigh what older panels can provide.

Electrical Tail

Electrical tails are part of your home’s electrical meter. It is installed by your power company when they hook your home up to the grid. The tail connects the meter to the grid. Your home must be completely up to date to have this installed. If you rewire your home, you should contact your electrical supplier and update your tail. Unless you are upgrading the meter on your own, the power company should supply these pieces and costs.

Main Earth

The main earth is the point in an electrical circuit where the power can be measured. It makes a direct physical connection with the ground. When you take a look at your circuit panel, you find various colored wires. Among the yellow and red wires, you should find a green wire. This green wire is the main earth. It is installed or upgraded when the rest of your circuit panel or wiring is upgraded.

Conduits

The conduit is a tube that contains the cables or wires. It can be rigid or flexible and made of metal or PVC. Conduits are part of the conduit wiring system. Conduit wiring involves running the wires through a containment area. The contained system does not use conduits - it uses slots cut into the wall. However, the wiring must run through something in a surface installation. In this case, the conduit is installed first, and the wires can run through it. Not all conduit wiring systems require the conduit.

Electrical Outlet Cost

An outlet is the connection point where you plug your appliances in to receive the electricity. Most rooms in the home have several outlets. Rooms like the kitchen or bathroom also have a GFCI or grounded outlet installed. Outlet installation is part of the house’s wiring or rewiring process. Costs of outlet installations are usually included. However, you can also have outlets installed individually if you need additional outlets. Installing an outlet costs between $85 and $274.

Telephone Jack

Telephone jacks and lines may also be installed during wiring or rewiring. Telephone jacks are less common in new homes and new home wirings, but they can be found in older homes and occasionally installed in new installations. This is the connection point for a mainline or landline telephone to make a connection for communication. With digital telephone lines and more people using cellphones instead of landlines, older jacks are no longer common. Installing a telephone jack costs around $131 on average.

Ethernet Jack

An ethernet jack is a connection point for communication via computer and other electronics. It can be part of the installation of a larger hardwired computer network. If you have an ethernet connection, such as a CAT 5 or CAT 7 system, you need at least one ethernet jack. For every computer you want to directly connect to or every room you want to connect in, you need a jack. This is not a common part of a home rewiring. If you choose to have this installed, it is part of a separate installation.

Cable Jack

This is the connection point for communication with a TV for a cable provider. It may also provide internet, depending on your provider and plan. This jack is usually installed by your cable company. This is a common installation in many of today’s homes. However, it is not typically part of your wiring or rewiring project. This is usually done when and if you choose to install cable or cable internet in your home.

Switches

Switches supply or terminate power to a specific junction, such as an outlet or light fixture. They are how you interact with your lights and other appliances. Switches can be single or multiple. They can also include things like dimmers that offer greater control of the lights. Some switches can also be connected to smart home systems. The cost of a switch installation is around $150 when not part of the overall lighting system.

Lights

Lights are a very important part of the wiring system, whether they are overhead, on the wall, a sconce, or recessed. When you rewire your home, the rough wiring for the lights is also updated or installed. However, the lights are not typically installed in this project. You purchase the lights separately. Sometimes, the installation can be added, but it depends on the light. Most lights require you to purchase and install them separately. Installing recessed lighting costs around $1,650 for six lights.

Cost of Electrical Work

Labor is the biggest part of a home wiring project. This is true whether you have a circuit panel upgraded or rewire your entire home. In either case, wiring for a project usually begins with mapping it out or determining what is needed and where. This can include light placement, switch placement, outlet placement, how many amps or volts a specific area needs, and what the panel needs to support this. The wiring can be installed in new construction right away, roughing in your outlets, switches, and lights at once.

When rewiring, your walls may need holes cut to remove the wires. Some of the wires can be reached from the attic, crawl spaces, or other areas that are easily accessed. If not, some of the walls may need to be opened entirely to remove the wires. If this is the case, you may have additional costs to refinish the walls.

In most cases, the circuit panel may be installed or upgraded at the same time and connected to the system.

This work is carried out by an electrician. A permit is required ahead of time, which includes the job’s plans and diagram. This is followed by an inspection to ensure all electrical safety codes have been met.

Electricians charge between $40 and $100 per hour, and rewiring an entire home may take up to a week. Smaller jobs may take one to two days, such as wiring a single room. Including the cost of all materials, it is common for electricians to price jobs by the square foot for the area being wired, between $3 and $5 per foot. Most homeowners pay around $4 for new installations. Costs range from $6 to $10 a square foot for rewiring, including wall opening and patching, old wire removal, and new wire installation.

Cost to Replace Knob-and-Tube Wiring

Knob-and-tube wiring is an older wiring type that is no longer used. It predates many upgrades that have happened and often uses materials that include fiber casings that can be a fire risk. The cost to replace this wiring is between $6 and $10 a square foot. You need to update to a circuit panel and replace all outlets, switches, and most of the wiring for the light fixtures at the same time. This may also mean updating the fixtures, but the fixture costs are not included.

Cost of Replacing Electrical Wiring in an Old House

Replacing electrical wiring in an old house is a very common project. Many materials used in older homes pose a fire risk, particularly with today’s appliances and electrical needs. Because of the extra amps needed, many old electrical systems can overload. Aluminum and cloth-wrapped wires can also pose a fire risk.

The cost of replacing the wiring in an old house is between $6 and $10 a square foot. This includes the cost of replacing all the switches and lights and upgrading to a circuit panel. It also means most of the light fixtures need new wiring. While the wiring is part of the total cost, the fixtures are not.

Electrical Inspection Cost

Electrical inspections should be carried out whenever a home is sold, particularly if it is older. If you have any concerns about the wiring in an older home, an inspection is a good idea. There are several things inspectors look for in an inspection, like the number of circuits, GFCI and AFCI circuit protection, electrical boxes, or proper cable anchoring, among other things. They tell you what wiring was used and how much the current panel can handle. This inspection costs between $125 and $250, depending on where you live, your home’s size, and how easy or difficult it is for the inspector to reach the wires.

Average Cost to Rewire a Mobile Home

The cost to rewire a mobile home ranges from $2,000 to $10,000, depending on the home size. Like stick-built houses, mobile homes that need rewiring require new outlets, switches, and a circuit panel. Like stick-built houses, the more difficult the wires are to reach, the higher the costs. Smaller mobile homes with easy-to-access wires are much less expensive to rewire than larger mobile homes with difficult-to-access wires.

Safety Codes

The National Electric Code exists to ensure all wiring jobs conform to a national standard for safety. Whether you are bringing an older home up to code or wiring a completely new house, some codes dictate which wires, cables, outlets, and ground faults are necessary in each room or area. Every wiring job must have a permit filed and an inspection after wiring to ensure these codes have been followed.

A full listing of safety codes can be found at the NFPA. Below are some ways these codes could impact your wiring job.

Bathroom

In the bathroom, your outlets must have GFCI protection, and you need at least one outlet within 3 feet of the sink. Built-in heaters need their own circuit. Otherwise, one circuit may supply the entire room. Anything used in the space must be rated for wet or damp conditions.

Kitchen

You need at least two outlets along the countertop in the kitchen, and major appliances like dishwashers need their own dedicated circuits. All outlets within 6 feet of the sink must have GFCI protection, and all lights must have their own circuit.

Living Rooms, Dining Rooms, and Bedrooms

All rooms in the home need a switch located within reach of the entrance. All walls wider than 2 feet must have an outlet, and outlets need to be 12-feet apart. If you have a large appliance in the room, such as a window air conditioner, it needs its own circuit.

Stairways

All stairs need a separate light source on their landing area. You must have 3-way switches at the top and bottom of the stairs.

Hallways

Hallways need a 3-way switch at each end. If the hallway is longer than 10 feet in length, it needs an outlet installed for general use.

Closets

Fixtures must be installed a minimum of 6 to 12 inches from the storage space, with the exact distance determined by the lighting type. If you have a surface-mount light, it must be installed on the wall or ceiling above the door.

Laundry Room

In the laundry room, all outlets must be GFCI protected. All appliances need their own circuit, with a clothes dryer requiring a 30-amp 240-volt circuit with 4 conductors.

Garage

Garages must be GFCI protected and need at least one outlet per car space. They also need their own circuit and to have at least one light switch installed.

Enhancement and Improvement Costs

Appliances

In many home remodels, wiring is not the only job an electrician undertakes. They may also set up appliances and alarm or security systems. Expect to pay between $100 and $500 for these services, depending on how many you have done.

Upgrading the Panel to a Higher Amperage

You may need to upgrade your panel to a higher amperage when rewiring your home. This costs around $2,500, depending on the existing panel.

Site Cleaning

In some instances, you may need to have the site cleaned after installation, before finishing work can continue. Some workmen will clean up after themselves, others will insist you hire a crew, at an additional cost of up to $500 depending on how much cleaning will take place.

Cost to Run Electric to a Shed

The cost to run electricity to a shed is $2 to $5 a square foot. The difference comes in the many ways a shed can be wired and finished. The shed could only need a single light fixture. It may also need multiple outlets for power tools, or it could need to support a space heater or air conditioner. The more power the shed needs, the higher the project’s total costs. If the shed is not finished, this keeps costs lower than if it has a finished interior.

Additional Considerations and Costs

  • Many aspects of home wiring can be done DIY, but this is not generally recommended. You must pull the permit, which means submitting a detailed and thorough diagram, completing the work safely, and then passing inspection. Unless you have some electrical knowledge already, it is best to leave this job to the pros.
  • If your home was built before 1960, you likely have knob-and-tube wiring, which must be removed before a new panel and wiring installation can be finished.
  • If the electrician finds any safety hazards or faulty wiring in your home during the course of the work, these must be fixed at an additional cost before continuing with the rest of the job.
  • NECA can help make sure you always hire a licensed professional, and we recommend you to get a written estimate before hiring an electrician. It should include a breakdown of the various costs involved in the project, including labor and materials. Your electrician can offer you additional information on finishing costs and recommend the type of work needed.
  • When installing wiring, many pros have to cut into wall surfaces to conceal the wires. This may require repairing or restoring some finishes and areas or replacing materials that were cut away. This can increase costs.
