Electrical Wiring Cost Guide: Rewiring, Upgrades & Per-Foot Pricing
Electrical work is one of the most critical and regulated aspects of home construction and renovation. Whether you are rewiring an older home, upgrading your panel for an EV charger, or adding circuits for a kitchen remodel, understanding electrician pricing helps you budget accurately and avoid unsafe shortcuts.
Quick answer
Whole-house rewiring costs $2–$6 per square foot ($4,000–$15,000 for a 1,500–2,500 sq ft home); a 200-amp panel upgrade runs $1,500–$4,000; a new outlet $150–$300; a new dedicated circuit $150–$300 plus $6–$10 per foot of wire. These are HammerIO planning estimates (national baseline adjusted by regional factors).
Labor is the largest line: the BLS OEWS May 2025 median electrician wage is $30.38/hr nationally, $49.21/hr in Chicago, IL-IN and $28.19/hr in Miami, FL. Contractors bill $75–$150/hr on top of that wage to cover the helper, truck, insurance and profit.

A complete house rewire costs $2 to $6 per square foot, or $4,000 to $15,000 for a typical 1,500 to 2,500 square foot home. This includes removing old wiring, running new Romex (NM-B) cable through walls and attic, installing a new panel, and connecting all outlets, switches, and fixtures. Homes with knob-and-tube wiring or aluminum branch circuits are rewiring priorities due to fire risk.
The biggest variable is wall access. If the electrician can fish wires through unfinished attic and basement spaces, costs stay lower. Homes with finished basements, cathedral ceilings, or slab-on-grade foundations require more drywall cutting and patching, adding $2,000 to $5,000 in wall repair costs. Use our drywall calculator to estimate patch materials.
Electrical Panel Upgrades
Many older homes have 100-amp or even 60-amp electrical service, which is insufficient for modern loads. A panel upgrade to 200 amps costs $1,500 to $4,000 including the panel, breakers, labor, and permit. Upgrading to 400 amps for homes with EV chargers, pools, and workshops costs $3,000 to $6,000. The utility company may also need to upgrade the service entrance, adding $1,000 to $2,500. If the upgrade supports EV charging, workshops, heat pumps, or other higher-load equipment, compare the monthly usage impact with JouleIO's electricity cost calculator.
| Service | Cost Range | Typical Duration |
|---|---|---|
| 100 to 200 Amp Panel Upgrade | $1,500-$4,000 | 4-8 hours |
| 200 to 400 Amp Panel Upgrade | $3,000-$6,000 | 1-2 days |
| Sub-Panel Addition (60-100 Amp) | $800-$2,000 | 3-5 hours |
| Service Entrance Upgrade | $1,000-$2,500 | 4-8 hours |
| Whole-House Rewire (1,500 SF) | $4,000-$9,000 | 3-5 days |
| Whole-House Rewire (2,500 SF) | $7,000-$15,000 | 5-7 days |
Per-Foot Wiring Costs
Running new wire costs $6 to $10 per linear foot for standard 14/2 or 12/2 Romex (NM-B) cable including labor and materials. Dedicated circuits for appliances use 10/3 or 8/3 wire at $8 to $15 per foot. Low-voltage wiring for data, phone, and speakers runs $1 to $3 per foot for cable plus $100 to $250 per termination point. Conduit installation for exposed or commercial applications adds $3 to $8 per foot.
Each new circuit also requires a breaker ($5 to $50 depending on type), a home run to the panel, and at least one outlet or device. Budget $150 to $300 per new circuit as a baseline, plus the per-foot wiring cost. A kitchen remodel that adds 4 to 6 dedicated circuits for appliances typically costs $1,000 to $2,500 for electrical alone.
Common Electrical Projects and Costs
- New outlet installation: $150 to $300 each. GFCI outlets for kitchens and bathrooms cost $20 to $40 more for the device.
- Ceiling fan installation: $150 to $400 including wiring. If no existing box is present, adding a fan-rated box costs $100 to $200 extra.
- Recessed lighting: $100 to $250 per fixture installed. LED retrofit kits for existing recessed cans cost $30 to $60 per light.
- EV charger circuit: $500 to $2,000 for a dedicated 240V, 50-amp circuit from the panel to the garage. Longer runs increase cost.
- Hot tub/spa circuit: $800 to $2,500 for a dedicated 50 or 60-amp GFCI-protected circuit with disconnect switch.
- Smoke detector hardwiring: $50 to $100 per detector for interconnected, hardwired units with battery backup.
Electrician Wages by Metro: Why the Same Job Costs More in Chicago
Every price above is labor-heavy, and electrician labor is priced locally. The table uses the Bureau of Labor Statistics' published median hourly wage for electricians in the ten largest U.S. metros. Chicago stands out at $49.21/hr, 62% above the U.S. median of $30.38, followed by New York ($37.99) and Washington ($36.50); the four Sun Belt metros, Miami, Atlanta, Dallas and Houston, cluster 6–7% below the median. The hours column prices a 70-hour whole-house rewire (a HammerIO planning assumption for a 1,500 sq ft home with reasonable attic access) at each metro's wage.

Signs You Need Rewiring
Several warning signs indicate your home's wiring needs professional attention. Frequently tripping breakers, flickering lights, warm or discolored outlets, a burning smell near outlets or the panel, two-prong outlets throughout the house, or a fuse box instead of a breaker panel all suggest outdated or overloaded wiring. Homes built before 1965 may have knob-and-tube wiring, and homes built between 1965 and 1973 may have aluminum branch circuits, both of which insurance companies increasingly refuse to cover.
If your home improvement plans include adding electrical loads like a workshop, hot tub, or EV charger, you may need both a panel upgrade and new circuits. Estimating the overall cost of your renovation helps with financing decisions. For major renovations, Amortio's mortgage tools can help you compare home equity loan options.
Permits and Inspections
Almost all electrical work beyond replacing existing devices requires a permit. Electrical permits typically cost $50 to $300 depending on the scope of work, verify the fee with your local building department. The permit process includes a plan review before work begins and one or two inspections during and after the work. Never let an electrician skip permits, as unpermitted electrical work can void your homeowner's insurance, fail a home inspection during sale, and most importantly, create fire hazards.
Frequently Asked Questions
How much does it cost to rewire a house?
Rewiring a house costs $4,000 to $15,000 for a 1,500 to 2,500 square foot home, or $2 to $6 per square foot. The final cost depends on the number of circuits, accessibility of walls and attic spaces, and whether drywall needs to be opened and repaired. Older homes with knob-and-tube or aluminum wiring are at the higher end.
How much does a 200 amp panel upgrade cost?
A 200 amp electrical panel upgrade costs $1,500 to $4,000 installed. This includes the new panel, breakers, labor, and permit fees. If the utility company needs to upgrade the service entrance cable from the meter to the panel, add $1,000 to $2,500. Most modern homes need at least 200 amps to handle air conditioning, electric dryers, and EV chargers.
Can I do my own electrical work?
Most jurisdictions require a licensed electrician for new circuits, panel work, and any wiring behind walls. Homeowners can typically replace outlets, switches, and light fixtures on existing circuits without a permit. However, electrical work is the leading cause of house fires, so hiring a licensed electrician is strongly recommended for safety and insurance compliance.
How much do electricians make per hour, and why is the contractor rate higher?
The BLS Occupational Employment and Wage Statistics (May 2025) median wage for electricians is $30.38 per hour nationally, ranging from $28.19 in Miami and $28.37 in Dallas to $37.99 in New York and $49.21 in Chicago among the ten largest metros. The rate a contractor bills, commonly $75 to $150 per hour, is higher because it also covers the helper, truck, tools, insurance, licensing, permits handling, and profit, not just the electrician's wage.
Which large metros have the cheapest and most expensive electricians?
Among the ten largest U.S. metros, BLS OEWS May 2025 median electrician wages are lowest in Miami ($28.19/hr), Atlanta ($28.20/hr), Dallas ($28.37/hr) and Houston ($28.45/hr), all about 7% below the U.S. median, and highest in Chicago ($49.21/hr, 62% above), New York ($37.99/hr), Washington DC ($36.50/hr) and Philadelphia ($35.86/hr). A 70-hour rewire therefore carries roughly $1,500 more in wage cost alone in Chicago than in Miami before overhead and profit.
