Wiring a 1,500-square-foot house typically costs $6,000-$13,500 for new construction, with an average near $9,000. The price depends on circuit count, outlet and fixture quantity, local labor rates, panel capacity, and whether walls are open or must be cut for a retrofit.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New-construction wiring | $6,000 | $9,000 | $13,500 | About $4-$9 per sq ft |
| Existing-home rewiring | $12,000 | $18,000 | $25,000 | Wall access and patching affect cost |
| Panel upgrade, if needed | $1,500 | $2,500 | $4,000 | Often a separate charge |
New wiring for 1,500 square feet usually costs $6,000-$13,500
For a straightforward new build with standard copper wiring, a typical panel, and ordinary access, expect about $4-$9 per square foot. The midpoint is roughly $6 per square foot, or $9,000 total. A basic layout with fewer circuits may fall near the low end; more fixtures, dedicated appliance circuits, or higher local wages can push the quote upward.
These figures cover typical residential wiring, not every electrical finish or specialty system. Confirm whether the estimate includes devices, light fixtures, panel work, permits, inspections, and final connection of appliances. Decorative fixtures and smart-home equipment are commonly priced separately.
Assumptions: U.S. average labor, standard copper cable, ordinary access, and a code-compliant basic layout.
What the electrician’s 1,500-square-foot quote includes
Labor and cable are the largest portions of a typical wiring bid. The sample ranges below describe a new-construction project; actual line items vary by contractor and location.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Wire, boxes, and devices | $1,500-$3,500 | $1-$2.35 per sq ft | Copper size, outlet count, device grade |
| Electrician labor | $3,000-$6,000 | $50-$100 per hour | Crew size, access, circuit complexity |
| Panel and breakers | $800-$2,000 | $800-$2,000 per panel | Amperage and breaker type |
| Permit and inspection | $150-$600 | Per project | Municipal fee schedule |
| Testing and finish work | $300-$1,000 | Per project | Fixture connections and corrections |
A quote is easier to compare when it separates labor, materials, panel work, and permit fees. Ask whether drywall repair, trenching, fixture installation, and utility coordination are excluded.
Panel capacity, circuit count, and access move the estimate
A 1,500-square-foot house might have roughly 40-70 outlets and switches, but room layout and code requirements matter more than floor area alone. Kitchens, laundry rooms, HVAC equipment, and electric ranges usually need dedicated circuits; adding these can raise material and labor needs.
Panel capacity is another significant variable. A standard 200-amp panel may be suitable for many homes, while a 100-amp panel or crowded existing panel may require an upgrade, commonly adding $1,500-$4,000. Long runs over about 50 feet, detached garages, or additional subpanels can add further expense.
Open framing generally costs less to wire than finished walls. In an existing home, fishing cable through plaster, insulation, or tight attic and crawlspace areas takes longer. Rewiring can cost $8-$17 per square foot, or about $12,000-$25,500 for this house size, especially if wall repair is included.
How to keep a 1,500-square-foot wiring project on budget
Finalize the room layout and outlet locations before rough-in. Changes after cable is installed can mean extra labor, new materials, and inspection delays. Grouping work while walls are open also avoids paying later to reopen finished surfaces.
Choose standard switches and outlets unless a specific room needs upgraded devices, and price specialty lighting separately. Compare at least three itemized bids with the same device count, panel scope, and permit assumptions. A low quote that omits testing or required circuits may not represent the lowest finished cost.
Keeping the scope stable and checking exclusions are the most practical ways to control the final bill. Do not reduce required circuits or skip permits to save money; local code and inspection requirements still apply.
Rewiring an existing home costs more than wiring new construction
New-construction electricians can install cable before drywall, with clear access to framing. Rewiring an occupied 1,500-square-foot house may require moving furniture, opening walls, working around insulation, and arranging patching and painting. A full rewire commonly lands around $12,000-$25,500 before extensive finish repairs.
Partial rewiring can cost less when the existing system is safe and only a defined area needs work. However, old wiring, damaged insulation, inadequate grounding, or an outdated panel may trigger broader replacement. A licensed electrician should inspect the system before a partial-work budget is treated as reliable.
Wall access, not just house size, explains much of the gap between new-build and retrofit pricing.
Electrician hours and project timing affect the total
A typical new-build job may involve roughly 60-100 electrician and apprentice hours across rough-in, device installation, and testing. At blended labor rates of $50-$100 per hour, labor can represent a large share of the total. Crew availability, local wage levels, and coordination with framing and drywall schedules affect the calendar and quote.
Emergency work or a compressed schedule can carry a premium, while planned rough-in during normal construction usually avoids after-hours charges. Get the expected crew size, estimated workdays, and hourly or fixed-price terms in writing.
Ask whether the bid is fixed-price or time-and-materials, and how approved changes are billed.
Regional labor rates can shift a comparable wiring bid
Rates vary across the country. Major coastal metros and high-cost urban markets may run about 15%-30% above a national-style estimate, while some rural or lower-cost regions may be 10%-20% below it. Travel distance, contractor availability, permit fees, and housing conditions can outweigh broad regional averages.
For example, a $9,000 baseline could become roughly $10,350-$11,700 in a higher-cost metro, or about $7,200-$8,100 in a lower-cost market, assuming the same scope. These are comparison estimates, not guaranteed local prices.
Three sample quotes show how scope changes the price
| Scenario | Scope | Estimated total | Effective rate |
|---|---|---|---|
| Basic new build | Standard panel, about 45 devices, open framing | $6,500-$8,000 | $4.35-$5.35 per sq ft |
| Typical new build | 200-amp panel, about 60 devices, dedicated kitchen circuits | $8,500-$11,000 | $5.65-$7.35 per sq ft |
| Complex retrofit | Finished walls, expanded circuits, some patching allowance | $17,000-$24,000 | $11.35-$16 per sq ft |
Compare each estimate by included work, not by total alone. Device counts, panel specifications, wall repair, and inspection fees should match before one bid can be judged against another.
