Electrical Wiring Cost by Different Type
Electrical wiring is running wires or cables to the cities of the house. This is done by the walls and usually includes ensuring the different components and connections are in place for use, such as outlets, switches, and panels. This process is easier in new house construction because it is done before the walls are finished. This makes the process easier and keeps costs down.
Electrical rewiring happens in a house with old wires that no longer work safely. It is more labor-intensive because older wires must be removed first.
| Type | Average 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 construction costs between $3 and $5 a square foot on average. Wiring for new house construction is considerably easier than for older houses. The electrical wiring goes in before the walls so that the process is easier and less labor-intensive. In most cases, new electrical wiring includes roughing in the wires, installing things like outlets, panels, and switches, and setting up 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 house and house owner’s needs, so it varies in overall costs.
Electrical Rough-in Cost
Roughing in the electricity costs between $3 and $6 a square foot. This is adding the electrical wiring but not finishing it. The electrical 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 electrical wiring cost, meaning you still need to pay $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 project, so the costs usually cost together even though they are done in two stages.
Cost to Wire a Basement
The average cost to electrical wire a basement is between $3 and $8 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 house construction – everything is roughed, the walls are finished, and the finished work begins.
Average Cost to Rewire a House
The average cost to rewire a house is between $8 and $12 a square foot. In electrical rewiring, all the current wires are removed and replaced with new electrical 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 electrical 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 electrically 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 of electrical rewire is closer to the cost 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.
| Location | Average Costs (Installed) |
|---|---|
| Kitchen | $470 – $1,710 |
| Garage | $1,252 – $2,560 |
| Room | $1,643 – $5,810 |

These costs range from the wiring during a remodel to updated wiring with the kitchen intact. They include the complete replacement of electrical 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 $1,252 to $2,560. 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 rewiting a garage are often lower than rewiring a similarly sized room in the home’s interior.

When rewiring a much larger or smaller room, your costs may be higher or lower. These electrical wiring 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 built 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 costed about the same, with similar cost ranges for installation, depending on the area and wire placement.
| Type of Wiring System | Average Costs per Square Foot (Installed) |
|---|---|
| Lead Sheathed | $5 – $8 |
| Conduit | $5 – $8 |

Lead Sheathed Wiring
Lead-sheathed electrical wiring costs between $35 and $8 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 electrical 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 electrical wiring ranges from $5 to $8 a square foot. This is the most common electrical 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 electrical wiring used in your house varies on accessibility, the home’s age, and the amount of space you have in the house’s walls and ceilings.
Electric Wire Cost by Material
When it comes to residential buildings, there’s quite a variety of cable types out there, over 22 to be exact! But not all of them are everyday household staples. When we’re talking about electrical wiring, you’re typically dealing with copper or aluminum wires, which can be insulated or sheathed in different materials like PVC. And here’s the thing, each wire has its own job—it could be hot, grounded, or neutral, depending on what it’s meant for. Now, when it comes to costs, in many cases, the wiring expenses are rolled into the overall labor cost. It’s all part of making sure your home’s electrical system is up to snuff!
| Type | Average Costs per Linear Foot (Material Only) |
|---|---|
| Multi-Conductor | $1.20 – $1.35 |
| Shielded Twisted Pair | $1.20 – $2.5 |
| Coaxial | $1.25 – $1.80 |

Stranded vs Solid Wire
If you have existing electrical wiring in your house, chances are that a large part of it is solid electrical wiring. Wiring comes in two types – stranded wiring, which is made up of multiple small copper strands, and solid wiring, which is made of one larger wire. Typically, solid electrical wiring was once used for most applications in residential homes because the most common size – #12 – can bend and move at this gauge.
However, stranded wiring is much more flexible and offers more placement opportunities. As houses require more wiring and connections, many electricians are switching to stranded. It bends and can be used in more areas than solid. This does not mean you need to remove all your old solid wire, just that any newer wires being added will likely be stranded simply for the benefit of flexibility. In fact, the solid wire can actually be a better conductor, but it is often too bulky at larger sizes to work well in meeting most modern residential homes’ needs.
Solid electrical wire is less expensive, however, so if you have a choice, consider the costs.
| Wire | Average Costs per Linear Foot (Material Only) |
|---|---|
| Solid | $0.60 – $0.80 |
| Stranded | $0.70 – $1.0 |
