Electrical Wiring Cost: Per Outlet, Per Room & Whole House (2026)

Electrical costs are the most opaque of all home construction pricing. Unlike flooring where you can measure square feet and multiply, electrical is priced by circuit, by fixture, by panel capacity, and by the condition of whatever is already in the walls. A seemingly simple “add an outlet” job can turn into a panel upgrade and circuit run if your existing service is maxed out.

This guide breaks down what you actually pay at every scale, from a single outlet to a complete house rewire, based on Bureau of Labor Statistics OEWS electrician wage data (May 2025), HammerIO planning estimates (national baseline adjusted by regional factors), and published contractor pricing surveys.

Electrician Labor Rates in 2026

Everything in electrical pricing starts with labor rates. Per the Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) program, the median hourly wage for electricians nationally was $30.38 in May 2025, but that's the employee wage. Contractor billing rates (what you pay) are typically 2.5–5x the wage to cover the helper, truck, tools, insurance, licensing, non-billable time, and profit.

Regional labor variation is significant and measurable. BLS publishes median electrician wages by metro: Chicago is $49.21/hr (62% above the U.S. median), New York $37.99/hr (+25%), Washington DC $36.50/hr (+20%), while Atlanta ($28.20/hr), Miami ($28.19/hr), Dallas ($28.37/hr) and Houston ($28.45/hr) all sit about 7% below it. Rural markets generally price below their nearest metro. The hours column prices a 70-hour rewire, a HammerIO planning assumption for a 1,500 sq ft home, at each metro's wage.

To see how labor hours turn into the wage portion of a quote, the table below multiplies HammerIO planning hours by the same BLS medians at the U.S. median and at the cheapest and priciest large metro. Materials, drywall repair, permits and contractor overhead and profit are added on top.

Cost to Add an Electrical Outlet

Installing a single outlet is the most common residential electrical job. The final cost depends on three variables: the type of outlet, the accessibility of the wall, and how far the new outlet is from the nearest circuit or panel.

The “fishing wire” problem: In new construction with open walls, adding an outlet takes 30–60 minutes. In a finished wall where wire must be fished through insulation and around fire blocks, the same job takes 2–4 hours, and sometimes requires opening drywall. Always ask your electrician upfront: “Will any drywall need to be opened?”

Also factor in: if you're adding multiple outlets on a new circuit, you pay the circuit run cost once and then a much lower per-outlet cost for additional outlets on the same circuit. Stacking work is always more cost-efficient than scheduling separate service calls.

Electrical Cost Per Room

“How much to wire a room?” is the second most common question I get. The answer depends heavily on what's already there (is this an addition with no existing wiring, or a remodel with existing circuits?) and what code requires for the room type.

The 2023 National Electrical Code (NEC), adopted in most jurisdictions, establishes minimum outlet spacing requirements: outlets must be placed so no point along any wall is more than 6 feet from an outlet (the “6-foot rule”). Kitchens require dedicated 20-amp circuits for countertop appliances. Bathrooms require at least one 20-amp GFCI circuit. Bedrooms built after 2008 require AFCI circuit breakers.

Kitchen electrical is the highest-cost room by far, the NEC requires dedicated 20-amp circuits for each small appliance circuit zone, a dedicated refrigerator circuit, a dedicated dishwasher circuit, and a dedicated circuit for the range or cooktop. In a remodel, this often means upgrading the panel to accommodate the new circuit load.

Whole-House Rewire Cost

A complete house rewire is one of the largest electrical investments you'll make, and one of the most important for safety and insurance eligibility. Per Angi's 2025 Cost to Rewire a House Report, the national average is $10,000–$30,000 depending on home size and complexity, with most 1,500–2,000 sq ft homes landing between $8,000 and $18,000.

What a Whole-House Rewire Includes

A complete rewire covers: new service entrance wiring from utility connection to panel; new electrical panel (typically 200-amp upgrade); all new branch circuit wiring (12 AWG for 20-amp circuits, 14 AWG for 15-amp circuits); new outlet, switch, and fixture boxes; new devices (outlets, switches, GFCIs, AFCIs per code); and all permits and inspections. It does not typically include light fixtures, ceiling fans, or appliance connections, those are separate line items.

When Rewiring Requires Opening Walls

This is the hidden cost variable. In a home being fully renovated (drywall coming off anyway), rewiring is relatively straightforward. In a home where the intent is to keep existing finishes, the electrician must “fish” new wire through walls and ceilings, which is slower, more expensive, and sometimes impossible without opening drywall at strategic points.

For older homes with knob-and-tube or aluminum wiring, most electricians and jurisdictions require full drywall access for complete circuit replacement. Budget $3,000–$8,000 for drywall repair and repainting after a rewire in a finished home.

Panel Upgrade Cost: 100-Amp to 200-Amp

The electrical panel is the hub of your home's electrical system. Most homes built before 1980 have 100-amp service, adequate for the appliance load of that era but insufficient for modern homes with EV chargers, heat pumps, induction ranges, and whole-house generators.

Per Angi's 2025 Electrical Panel Cost Report:

Panel upgrades require utility coordination, the utility must disconnect service temporarily during the work, which may involve a scheduling delay and a separate utility fee ($75–$200). The permit process for panel upgrades typically requires a utility-approved inspection before power is restored.

Specific Electrical Project Costs

EV Charger Installation: $800–$2,500

A Level 2 EV charger (240V, 32–48 amp) requires a dedicated circuit and often a panel upgrade. Per the U.S. Department of Energy's Alternative Fuels Station Locator data and contractor pricing, installation costs $800–$1,500 when the panel has capacity and the garage is close to the panel. Add $500–$1,500 if a panel upgrade is needed, or if the circuit run exceeds 50 feet. Before adding high-load circuits, model the ongoing utility impact with JouleIO's electricity cost calculator.

Whole-House Generator Connection: $3,000–$7,000

Connecting a standby generator requires a transfer switch ($300–$900 for materials), installation of the transfer switch at the panel ($500–$1,500 labor), running new circuit wiring, and often a permit and load calculation. Natural gas or propane generators add plumber costs. A properly installed whole-house transfer switch setup runs $2,000–$5,000 installed, not counting the generator itself.

Aluminum Wiring Remediation: $2,500–$12,000

Homes built between 1965 and 1973 frequently have aluminum branch circuit wiring. Aluminum wiring is not inherently dangerous, but connections at outlets, switches, and fixtures are a fire risk if not properly maintained. Per the U.S. Consumer Product Safety Commission (CPSC), homes with aluminum wiring are 55 times more likely to have a fire hazard at electrical connections than copper-wired homes.

Remediation options: full rewire (most thorough, $8,000–$20,000); pigtailing (adding copper connectors at every device, $2,500–$8,000); or CO/ALR-rated device replacement ($1,500–$4,000 for device swap only). Full rewire is the only option many insurers will accept, check your policy before choosing a cheaper partial fix.

Warning Signs That Require Immediate Electrical Work

Per the NFPA's 2025 Home Structure Fires Report, electrical failures and malfunctions caused an estimated 46,700 home structure fires in the U.S., resulting in 390 deaths and $1.4 billion in property damage. These are the red flags that should prompt an immediate electrician call:

• Circuit breakers that trip repeatedly or won't reset
• Outlets or switches warm or hot to the touch
• Burning or plastic smell near outlets, panels, or fixtures
• Flickering lights (especially when appliances cycle on)
• Sparks or arcing when plugging in devices
• Discolored or charred outlet faceplates
• Buzzing or humming from walls or the panel
• Fuse box instead of circuit breakers (older technology, limited capacity)

How to Get an Accurate Electrical Bid

Electrical bids are notoriously variable because labor hours, wall access, and panel capacity are judgment calls. Getting three or more written bids on an identical scope is the single most reliable way to avoid overpaying.

When requesting bids, provide the same written scope to every contractor:

• Square footage and stories
• Current panel size and age
• Specific scope (new circuits, panel upgrade, full rewire)
• Whether walls are open or finished (critical for labor estimates)
• Code compliance requirements (AFCI, GFCI locations)
• Who is responsible for permit, inspection, and utility coordination

Ask every electrician to itemize their quote: labor hours, material costs, and permit/inspection fees listed separately. This makes comparison accurate and gives you line-item leverage if you need to reduce scope.

Permits and Inspections: What They Cost and Why They Matter

Electrical work is one of the most strictly permit-regulated trades in residential construction, for good reason. Per HomeAdvisor's 2025 permit cost data, electrical permits run:

• Minor work (1–3 circuits, outlets, switches): $50–$150
• Room addition or basement wiring: $100–$350
• Panel upgrade: $150–$400
• Whole-house rewire: $200–$600

The inspection is where the permit fee earns its value. A licensed inspector catches wrong-gauge wire, missing GFCI protection, and overcrowded junction boxes, mistakes that cause fires. Electricians who refuse to pull permits are a red flag. In most states, only a licensed electrician can legally pull an electrical permit.
