If you’re buying, selling, or renovating a home in Nassau County, a home inspection is almost always part of the process. And when that inspector flips open the panel or starts testing outlets, a few common electrical code violations can stop everything in its tracks.

Here’s what typically gets flagged during inspections, why it matters, and how to avoid it with the help of a licensed electrician.

Bar chart showing the most common electrical code violations found during Long Island home inspections. Top issues include missing GFCI protection, double-tapped breakers, and open wire splices, with frequencies ranging from 7% to 35%.

1. Missing or Improper GFCI Protection

GFCI outlets are required in areas with moisture like kitchens, bathrooms, garages, laundry rooms, and outdoor spaces. If your home was built before modern code updates, you may be missing them altogether.

Even if you do have GFCIs, they may be installed incorrectly or not working at all. Inspectors always test these. If they don’t trip properly, it’s a red flag.

Fix it: A licensed electrician can replace outdated outlets with proper GFCI protection and test each one to ensure it’s up to code.

2. Double-Tapped Breakers

A “double-tap” means two wires are connected to a single breaker terminal that was only designed for one. This is one of the most common violations found during home inspections, especially in older homes.

It’s not always dangerous, but it is a code violation and can cause overheating or tripping issues if not corrected.

Fix it: This often requires installing a new breaker or rewiring the panel. It’s usually a quick fix for a professional.

3. Open Splices and Improper Wire Connections

Open wire splices are a major fire hazard. You might find them in basements, attics, garages, or behind walls where someone DIY’d a quick electrical patch. If wires are connected without a proper junction box and cover plate, inspectors will flag it immediately.

Fix it: All splices should be housed in accessible junction boxes with approved connectors and covers. An electrician can track these down and correct them quickly.

4. Overloaded or Outdated Electrical Panels

If your home still has a fuse box or a small panel that doesn’t support modern electrical loads, expect it to show up on your inspection report. Overloaded panels and panels from recalled brands like Zinsco or Federal Pacific are especially problematic.

Fix it: Upgrading your electrical panel not only keeps your home safe but also adds value. It’s one of the most impactful electrical updates a homeowner can make.

5. Ungrounded Outlets

Many older homes still have two-prong outlets without a ground wire. These are no longer up to code and can pose a shock risk to you and your electronics.

Some homeowners try to install three-prong outlets without grounding them, which actually makes things worse.

Fix it: A licensed electrician can test the circuits and either run a new ground wire or install GFCI-protected outlets as an alternative, depending on what the code allows.

6. No Smoke Detectors or Improper Placement

Every bedroom, hallway, and level of your home should have a working smoke detector. Some towns also require carbon monoxide detectors. If they’re missing, expired, or not interconnected, your home inspector will flag it.

Fix it: Install code-compliant smoke and CO detectors. Most modern systems are hardwired with battery backups, and your electrician can make sure they meet local requirements.

7. Extension Cords Used as Permanent Wiring

It’s surprising how often inspectors find garages, sheds, or basements wired with extension cords or power strips. While it might seem like a harmless shortcut, it’s a clear code violation and a serious fire hazard.

Fix it: Have an electrician install proper outlets or circuits where needed. It’s safer, cleaner, and completely code-compliant.

8. Light Fixtures Without Boxes

If someone mounted a ceiling light or wall sconce directly onto drywall without an electrical box, it’s not up to code. Fixtures need to be securely attached to an electrical box that supports their weight and wiring.

Fix it: Electricians can install retrofit boxes and rewire the fixture safely.

9. No Permit or Inspection History for Prior Work

If the electrical work in your home was done without a permit or inspection, it’s a liability. Inspectors and buyers alike will raise concerns about safety and code compliance.

Fix it: Have a licensed electrician inspect the work and file for a retroactive inspection if needed. This helps legitimize the work and protects your investment.

How to Avoid These Violations

The best way to avoid these issues is to work with a licensed and insured electrician who knows the local codes inside and out. Here in Nassau County, every township has its own requirements, and even simple jobs often require permits and inspections.

Before listing your home or starting a renovation, schedule a code compliance check. Fixing small issues now can save you time, money, and stress during the inspection process later.
