When planning to build a new garage, there’s a lot to think about—permits, design, materials, and of course, the construction process itself. But one critical detail that often surprises homeowners is something called a ComEd electrical sleeve. Addressing this early in the planning stage can save you time, money, and headaches down the road.

What Exactly Is a ComEd Sleeve?

A ComEd sleeve (sometimes referred to as an electrical conduit sleeve) is a protective casing or pipe that encases and shields the overhead electrical service wires that may run through the area where your new garage is being built.

If your home’s electrical service lines are overhead—meaning they connect from the utility pole to your home through the air—those lines can sometimes cross directly above where your new garage is planned. This presents a potential safety hazard to both the construction crew and your future structure.

To address this, ComEd (Commonwealth Edison)—the utility company responsible for electrical service in most of northern Illinois—may need to install a sleeve or reroute the electrical service so it’s safely protected or moved before construction begins.

Why It’s Necessary Before Construction Begins

1. Safety for the Crew and Property
   Working around live electrical lines is extremely dangerous. Before framing can start, any low-hanging or crossing electrical wires must be addressed to prevent accidental contact. Installing a ComEd sleeve ensures that everyone working on-site remains safe throughout the building process.
2. Compliance with Building Codes
   Municipalities and building departments require that all structures maintain safe clearance from power lines. If your garage is too close to an overhead service, you won’t be able to pass inspection or move forward with the build until it’s corrected.
3. Avoiding Construction Delays
   If a ComEd sleeve or electrical relocation is needed, the process can take several weeks from the time it’s requested. Identifying this need early in the design phase helps prevent delays once construction is ready to start.
4. Protecting Your Investment
   Your garage is a significant investment. Ensuring all electrical service issues are handled properly before the build begins helps protect your new structure—and your home’s electrical system—from potential damage or future complications.

How the Process Works

Typically, once your garage design and site layout are finalized, your builder will assess the area for any overhead electrical obstructions. If wires cross the build site, they’ll contact ComEd to request a field visit. ComEd will then determine whether:

• The wires can be raised, rerouted, or encased in a protective sleeve, or
• The electrical service needs to be temporarily disconnected or permanently relocated underground.

Once the sleeve is installed or the service is rerouted, construction can proceed safely and without interruption.

Before your new garage takes shape, make sure the ComEd sleeve question is addressed. It may seem like a small detail, but it’s a crucial part of preparing your site for a safe, code-compliant, and efficient build. At Heartland Garage Builders, we are here to help navigate that process.
