It’s time for electrical inspections again. You might think, “Everything looks fine, so why do I need this?” If there are no issues, no sparks, and everything works well, it’s normal to question the need for an inspection.
Many homeowners feel this way because they are not aware of what will fail an electrical inspection, and small problems can go unnoticed, even if everything seems fine.
This article covers common issues inspectors find and offers practical tips to help you avoid them, ensuring your home passes.

Why Electrical Inspections Fail: 10 Common Issues Inspectors Flag
#1: Electrical Panel Problems
The electrical panel is the main reason inspections fail. As the system’s control center, any issues here can affect the entire building and are often marked as high-priority safety risks.
Common panel problems include:
- Double-tapped breakers happen when two wires are connected to a breaker that is not made for it. This can cause overheating, arcing, or even fires.
- Overcrowded wiring means there are too many wires in the panel. This raises the chance of damaged insulation and unsafe connections.
- If filler plates are missing, open slots in the breaker panel can expose live electrical parts. This increases the risk of shock or fire.
- Poor circuit labeling, such as missing or wrong labels, can make it unsafe to turn off power during emergencies or repairs.
- Outdated or unsafe panels, especially old or recalled models, might not trip when they should. This can increase the risk of electrical fires.
At PDX Electric, we find and fix panel issues to help keep your home safe and running smoothly. Get in touch with us for a fast, reliable inspection.
#2: Improper Grounding and Bonding
Grounding and bonding help keep you safe from electrical shocks and fires.
- Grounding connects your electrical system to the earth using a metal rod. This way, electrical surges can safely move into the ground.
- Bonding links all the metal parts of your system together and to the grounding system. This gives electricity a safe path to follow during an emergency.
If grounding or bonding is missing or done incorrectly, especially in older homes, inspectors usually notice this during checks. Without proper grounding or bonding, power surges have nowhere safe to go. This can cause electric shocks or fires if breakers or fuses fail.
#3: Missing or Faulty GFCI Protection
GFCI (Ground Fault Circuit Interrupter) outlets help keep you safe by spotting electrical imbalances and shutting off power if something goes wrong. It’s important to have them in kitchens, bathrooms, garages, laundry rooms, and outside, where moisture can increase the risk of electric shock.
Inspectors make sure GFCI outlets are not only installed but also working as they should. They press the “Test” and “Reset” buttons to check if the outlet shuts off power when there’s a problem. If the GFCI does not trip during the test, or if it is missing where required, the inspection may not pass.
#4: Lack of Required AFCI Protection
An Arc Fault Circuit Interrupter (AFCI) helps prevent electrical fires by detecting arc faults, which are sudden sparks in wiring caused by faulty appliances, loose connections, or damaged wires. If an arc is detected, the AFCI quickly shuts off the power to stop a fire from starting.
Building codes require AFCIs in places where wiring is used a lot, such as living rooms, hallways, and bedrooms. Most circuits in newer homes need AFCIs, especially in areas with old wiring or a higher risk of fire. These devices should also be added during upgrades to older homes, since they are sometimes overlooked.
Inspectors often point out when AFCIs are missing because these devices help prevent fires. Without AFCIs, arc faults can lead to fires that could have been avoided.
#5: Outlet and Switch Wiring Errors
Inspectors check outlet and switch wiring for problems that might create safety risks, such as:
- Reversed polarity: Hot and neutral wires are switched, which can cause electrical shocks.
- Open grounds: The grounding wire is not connected, so devices are more likely to be damaged by surges or cause shock hazards.
- Loose outlets or switches: Poor contact can lead to overheating and raise the risk of fire.
- Improperly installed switches: If the wiring is incorrect, it can overload circuits or cause shock risks.
Even if outlets and switches look fine, there can still be hidden problems. Inspectors point these out because they could cause shocks or fires. These issues need to be fixed to meet code and keep everything safe.
#6: Exposed Wiring and Missing Cover Plates
Inspectors see exposed wiring, open electrical boxes, and missing or broken cover plates as serious safety risks. Electrical boxes and cover plates help prevent heat, sparks, and accidental contact. Without them, live wires are easy to touch, which can cause shocks or electrocution.
These issues also raise the risk of fire. Exposed wires can be damaged by movement, pests, moisture, or everyday use. If a wire sparks or gets too hot, it could start a fire. Cover plates also keep out dust and debris, which helps lower fire risk.
Inspectors often point out these problems because they are simple and cheap to fix, but people often miss them. They might also show there are hidden electrical issues, so they need to be fixed before you can get approval.
#7: Improper or Unpermitted DIY Electrical Work
Inspectors pay special attention to any electrical work done by homeowners because it can create safety hazards and break code rules. DIY fixes might look like a way to save money, but they often lead to mistakes that cause inspection failures.
Some common mistakes are:
- Using the wrong type or size of wire, or using wire that is not approved for certain areas
- Twisting wires incorrectly, using the wrong connectors, or leaving wires exposed
- Not installing junction boxes or using boxes that are too small
- Installing light fixtures or outlets incorrectly, such as using the wrong polarity or not securing the connections properly
Doing electrical work yourself can put your property and electrical system in danger. Permits and licensed professionals are required to keep everything safe and up to code. If you do the work on your own, you could face safety problems and fail the inspection.

#8: Overloaded Circuits and Insufficient Electrical Capacity
Today, people use more devices and appliances both at home and at work. This puts extra strain on older electrical systems. If wiring and panels are outdated, they may not handle the increased demand, which can cause breakers to trip more often or lead to electrical fires. Plugging too many devices into one circuit can also overload it, damage the system, or start a fire.
Many older homes have service panels that are too small for today’s electrical needs. Modern appliances, electronics, and HVAC systems often require at least 200 amps, but older homes may only have 60 or 100-amp panels. This gap puts extra stress on the system, causing breakers to trip more often and increasing safety risks.
Inspectors pay close attention to these issues because overloaded circuits and small panels are clear safety risks.
#9: Outdated or Unsafe Wiring Types
Wiring that was safe in the past may not be safe today because electrical codes have changed, and modern homes use more electricity.
Inspectors often point out old wiring types such as knob-and-tube, aluminum, and cloth-covered wiring. These can wear out quickly and may not safely handle the amount of electricity used in homes today.
Upgrading old wiring helps your home meet current electrical needs and safety codes. Inspectors suggest replacing old systems to avoid problems that could lead to shock, fire, or electrocution.
#10: Outdoor, Garage, and Utility Area Issues
Outdoor, garage, and utility spaces often fail inspections due to problems with weather protection and wiring. Outdoor outlets need weatherproof covers and GFCI protection to keep out moisture, which can be dangerous. In garages and utility rooms, exposed wiring or missing conduit is also a safety risk.
These areas need safety features such as proper grounding, enough space around electrical panels, and good lighting. If any of these are missing, inspectors will notice since codes require them to help prevent fires, electric shocks, or other accidents.
How Homeowners Can Reduce the Risk of Failing an Electrical Inspection
To avoid failing an electrical inspection, take a proactive approach to managing your home’s electrical systems. Understanding what will fail an electrical inspection can help you address issues early. Try these steps:
- Hire a licensed electrician to do a pre-inspection. They can find and fix problems before the official inspection.
- Take care of any known issues as soon as possible. If you have old wiring, overloaded circuits, or the wrong type of outlets, fix them right away.
- Make sure you have GFCI outlets in places like kitchens, bathrooms, garages, and outside. These help prevent shock hazards.
- Replace any outdated wiring. If your home has knob-and-tube or aluminum wiring, update it to meet today’s safety standards.
- Look for common problems such as exposed wires, missing cover plates, or poor grounding, especially in utility rooms and outside areas.
- If you’re buying or selling a home, get an electrical evaluation early. This lets you fix any issues before they cause delays or problems.
