Rewiring a house is not just about replacing old wires—it’s a major safety upgrade, a long-term investment, and a significant enhancement to your home’s value. If you’re a homeowner in the Garden State, understanding how much it costs to rewire a house in New Jersey is crucial before taking the plunge.
This comprehensive guide will walk you through every aspect: from pricing estimates and factors to expert tips, safety standards, local regulations, and real-world ROI.
Average Cost to Rewire a Home in New Jersey
On average, rewiring a home in New Jersey costs between $7,000 and $15,000, depending on several variables like home size, wiring accessibility, labor rates, and panel upgrades.
Home Size (sq. ft.) |
Estimated Cost Range |
1,000 |
$3,000 – $7,000 |
1,500 |
$4,500 – $10,500 |
2,000 |
$6,000 – $14,000 |
2,500 |
$7,500 – $17,500 |
3,000 |
$9,000 – $21,000 |
Includes materials, labor, new fixtures, and permit fees.
Key Factors That Affect the Cost
1. Age of the Home
Older homes, especially those built before 1970, often contain knob-and-tube wiring or aluminum wiring, which are outdated and unsafe.
Replacing these adds to the complexity and cost.
2. Accessibility of Wiring
Wiring that runs through finished walls, tight crawlspaces, or behind heavy fixtures requires more labor.
Homes with attics or unfinished basements are easier (and cheaper) to work with.
3. Electrical Panel Upgrade
Modern households need 200-amp service to run appliances, HVACs, and EV chargers.
Upgrading your electrical panel typically costs an additional $1,200 – $2,500.
4. Construction Type: New vs. Existing Homes
- New Construction: $4 – $6 per sq. ft. (easier access, fewer obstructions)
- Existing Homes: $6 – $10 per sq. ft. (requires drywall cutting and repairs)
Rewiring during a remodel or renovation saves cost on wall restoration.

Common Electrical Rewiring Myths Debunked
“I Can Just Add More Outlets Instead of Rewiring”
More outlets on an outdated or overloaded circuit increases fire risk. Rewiring gives each area its own safe circuit.
“I Don’t Need Permits If It’s My Own Home”
In NJ, all major electrical work requires permits and inspections—even in owner-occupied homes.
“If the Lights Work, the Wiring Is Fine”
Old or degraded wiring may still function, but it poses unseen risks. Inspections are necessary to assess hidden conditions.
Rewiring a House vs. Upgrading Just the Panel
Many homeowners confuse these two. Here’s a simple breakdown:
Feature |
Panel Upgrade Only |
Full Rewiring |
Replaces the main breaker box |
|
|
Adds more amps (e.g., 200A) |
|
|
Installs new wires inside walls |
|
|
Replaces outlets & switches |
|
|
Brings wiring to modern codes |
|
|
Sometimes, both are required depending on the home’s age and load demand.
Creating a Home Electrical Logbook
After the rewiring is complete, maintain a digital and printed record for safety, resale, and future renovations.
What to Include:
Electrical permit and inspection paperwork
Breaker load schedule and circuit map
Photos of wiring while walls are open (for reference later)
Warranties on materials and labor
Contact info of your electrician and subcontractors
This can impress buyers and simplify troubleshooting years later.
How Rewiring Affects Home Inspection Reports and Appraisals
When you rewire a home in New Jersey, it directly influences how your home is perceived by licensed home inspectors and professional appraisers.
Appraisal Value Boost
- Homes with modern, safe wiring often receive a “modernized systems” classification, increasing the property’s market value.
- Appraisers factor in the lifespan of the electrical system, placing rewired homes in a favorable category for mortgage underwriting.
What Inspectors Look For:
Modern 3-prong grounded outlets
GFCI and AFCI compliance
Updated electrical panel with clear labels
No visible aluminum or cloth-insulated wiring
Securely mounted junction boxes and accessible service points
Tip: Ask your electrician to provide documentation to hand over to your inspector or appraiser.
Understanding Electrical Load Needs Before Rewiring
Modern homes require much higher electrical loads than those built 20–40 years ago. A full rewire allows your circuits to be redesigned around your home’s current and future power usage.
Today’s Power-Hungry Devices:

- HVAC systems with smart thermostats
- Electric vehicle chargers
Electricians use load calculation formulas to ensure each new circuit can handle your usage without tripping.
Rewiring & Home Remodeling: Do Them Together and Save
If you’re planning to remodel—kitchen, bathroom, or full-home—this is the smartest time to rewire.
Why Rewiring During a Remodel Saves Money:
- Walls are already open (no extra demo costs)
- Drywall, flooring, or paint touch-ups are already planned
- The permit process can be bundled together
- You can consolidate labor hours and inspections
Many New Jersey homeowners save up to 25% when bundling rewiring with major renovations.
Upgrading Your Electrical System to Accommodate Aging-in-Place
If you or your family members plan to age in place, consider making your home safer and more accessible during the rewiring process.
Aging-Friendly Electrical Upgrades:
Illuminated toggle switches
