⚡ What’s Involved in a Commercial Electrical Inspection?

A Guide from Mook Property Inspections

When it comes to commercial properties, the electrical system is more than just switches and outlets—it’s the backbone of the building’s operations, supporting everything from lighting and HVAC to life safety systems and industrial equipment. At Mook Property Inspections, we conduct thorough electrical inspections in accordance with the Certified Commercial Property Inspectors Association (CCPIA) and the ComSOP—the gold standard in the industry.

🔍 What Is the ComSOP?

The ComSOP (Commercial Standards of Practice) outlines the scope, depth, and methodology that a qualified commercial inspector follows. While not code enforcement, it ensures consistency, professionalism, and a safety-oriented approach.

According to the ComSOP, a commercial electrical inspection is a visual, non-invasive examination designed to identify visible and accessible deficiencies that may compromise safety or functionality.

⚙️ What’s Included in a Commercial Electrical Inspection?

At Mook Property Inspections, our electrical evaluation includes—but is not limited to—the following:

🧰 Electrical Service

• Main panel location and accessibility

• Service amperage and labeling

• Presence of multiple panels or subpanels

• Grounding and bonding

• Clearance and safety barriers

🔌 Panelboards

• Inspection of panel covers, breakers, and wiring

• Look for signs of overheating, arcing, or corrosion

• Ensure breakers are labeled and accessible

• Check for open knockouts or double-tapped breakers

⚡ Wiring & Conduits

• Verify visible conductor types and conditions

• Look for exposed wiring, improper splices, or lack of conduit protection

• Assess conductor support and protection from physical damage

💡 Lighting Systems

• Functionality of interior and exterior lighting

• Condition of emergency and exit lights

• Verification of occupancy sensors and timers (where applicable)

🔘 Devices & Fixtures

• Inspect a representative number of switches, outlets, and GFCIs

• Identify missing or damaged cover plates

• Test functionality and polarity

🧯 Life Safety Systems

• Confirm presence of emergency shutoffs (for kitchens or labs)

• Inspect fire alarm panels, strobes, horns, and smoke detectors (visually)

• Verify exit signage and power backup if visible

🚨 Common Electrical Defects Found in Commercial Buildings

During inspections, we often uncover a range of issues—some simple, others critical. Here are some of the most common defects:

⚠️ Overloaded Circuits or Panels

Many older buildings have not been upgraded to handle the demands of modern equipment, leading to overloaded circuits that pose fire risks.

🧯 Missing or Improper Grounding

Improper grounding is both a safety hazard and a code violation. We often find disconnected or loosely terminated grounding wires.

🔧 Double-Tapped Breakers

A common defect where two wires share a single breaker, which can lead to overheating or tripped circuits.

🔌 Exposed or Damaged Wiring

Especially in warehouses or mechanical rooms, it’s common to find exposed or damaged conductors, often without proper conduit or protection.

💡 Non-Functional Exit or Emergency Lighting

Exit and emergency lighting are often overlooked in maintenance, yet critical for occupant safety during power outages or evacuations.

🛠 Unlabeled or Mislabeled Panels

Improper labeling slows down emergency response and violates OSHA safety protocols in many commercial environments.

🧠 Why It Matters

An electrical issue in a commercial building can have far-reaching consequences, including equipment damage, tenant complaints, fire risk, or even injury. That’s why we provide detailed reports with photos, descriptions, and recommendations—so owners, managers, and buyers can make informed decisions.
