If your New Jersey home was built before 1950, there’s a good chance it still has knob-and-tube wiring, or worse, a Federal Pacific electrical panel. These outdated systems are red flags for buyers, home inspectors, insurance carriers, and municipal code officials. Whether you’re preparing to sell or just want to know where you stand, here’s what you need to know.
What Is Knob-and-Tube Wiring?
Knob-and-tube wiring was the standard in American homes from the late 1800s through the 1940s. It uses ceramic knobs to hold wires in place and ceramic tubes to route them through framing. Unlike modern wiring, it lacks a grounding wire, making it more prone to electrical fires and shock hazards.
While legal in some towns if it’s still functioning properly, knob-and-tube wiring is no longer considered safe by modern standards. In fact, some New Jersey municipalities will not issue a Certificate of Occupancy unless the wiring is replaced.
Knob-and-tube wiring was never intended to handle today’s electrical load: dishwashers, microwaves, HVAC systems, chargers, and entertainment systems simply didn’t exist when these systems were installed. Add to that the fact that insulation may be brittle or missing, and the result is a high-risk scenario hiding behind the walls.
Real-World Example: A Costly Oversight in Westwood
Let me give you a real example that recently played out in Westwood, NJ. A friend of mine watched his ex-wife list her home with an out-of-area real estate agent who had no local knowledge of the housing stock or common inspection issues. The home, a charming colonial built in 1926, still had active knob-and-tube wiring.
The agent never warned the seller that this could be a major issue. The home hit the market, got strong interest, received multiple offers, and she accepted an offer significantly over the list price. Sounds great, right? Except after the buyer’s inspection, they demanded that all of the knob-and-tube wiring be removed and replaced with modern electrical.
Now the seller is facing a $20,000 electrical upgrade she hadn’t budgeted for. The deal is hanging in limbo, and the seller is stressed and angry. A more experienced agent would have flagged this issue upfront and either priced accordingly, disclosed properly, or offered the property as-is to a buyer who could handle it.
Knob-and-Tube Wiring and New Jersey’s Certificate of Occupancy Rules
In many Bergen County towns, sellers must obtain a Certificate of Occupancy or Continued Certificate of Occupancy before transferring ownership. Towns like Fair Lawn, Teaneck, and Englewood have stricter inspection standards and frequently flag outdated electrical systems.
If knob-and-tube wiring is present, even if it’s working, you may be required to replace it or bring in a licensed electrician to certify that it’s safe. That certification isn’t always easy to get, especially if the system has been modified over the years.
Towns vary in how they enforce these rules, but the trend is toward stricter safety enforcement, especially as municipalities face liability from house fires linked to outdated wiring.
What About Home Insurance?
Most insurance carriers in New Jersey will either refuse to insure a home with active knob-and-tube wiring or charge a premium with severe exclusions. Some may demand an electrical inspection, and if knob-and-tube wiring is discovered, coverage could be denied or revoked.
Even if you already have coverage, your insurer may refuse to renew once they find out. If you’re trying to sell, this can create a domino effect. Your buyer may not be able to obtain insurance, which means they can’t close on the mortgage. And now your deal is in jeopardy.
Federal Pacific Panels: Another Hidden Time Bomb
Even if your home has been partially rewired, another common issue in older homes is the Federal Pacific Electric panel, often branded as Stab-Lok.
These panels were widely used from the 1950s through the 1980s and are still found in many older homes throughout North Jersey, including Emerson, where I have sold several homes. In fact, I see Federal Pacific panels come up in almost every older home in Emerson.
Here’s the problem: Multiple safety tests have shown that Stab-Lok breakers fail to trip during overcurrent situations, which can cause wires to overheat and start a fire. A study by the Consumer Product Safety Commission found that up to 1 in 3 breakers fail to trip when needed.
Although never formally recalled at the national level, Federal Pacific panels are widely considered unsafe by electricians, inspectors, and insurance carriers. Many towns and lenders require them to be replaced before a Certificate of Occupancy or closing can be issued.
How Much Does It Cost to Rewire a Home or Replace the Panel?
- Full knob-and-tube removal and rewiring: $8,000 to $20,000 or more
- Federal Pacific panel replacement: $1,500 to $3,500
- Electrical inspection and permits: Additional $500 to $1,000 depending on town
Costs vary based on the size and layout of the home, accessibility to walls, whether the home is occupied, and whether patching or plaster repair is needed.
Homeowners should also factor in the time and disruption of opening walls, coordinating contractors, and waiting for municipal inspections to sign off on the work.
What If You Can’t Afford to Upgrade?
Let’s be realistic: not everyone can drop $20,000 or more to upgrade their electrical system, especially if they’re selling an inherited property, retiring, or dealing with other financial issues.
If your home still has knob-and-tube wiring, a Federal Pacific panel, or both, and you don’t want to spend the money or time to renovate, selling to an investor might be a smart option.

Final Thoughts
Knob-and-tube wiring and Federal Pacific panels are more than just outdated. They are dangerous, costly, and often deal-breakers. In towns like Emerson, Fair Lawn, and Teaneck, they can prevent you from getting a Certificate of Occupancy or delay your sale indefinitely.
If you’re unsure whether your home’s electrical system will pass inspection, get ahead of it now. Talk to a licensed electrician or a local real estate expert who understands what buyers and towns expect.
And if you’re ready to move on without the hassle of upgrades or repairs, NJ House Partners is here to help you sell quickly, safely, and without judgment.
