You’ve finally decided to put up the fence you’ve been wanting. Then it hits you: what’s actually buried under your yard? Gas lines, electrical cables, water pipes, communication lines. The thought of accidentally hitting one of them is enough to make anyone pause. That concern is completely valid. Across the country, an underground utility line is damaged every nine minutes because someone started digging without checking first.
At Fence Masters, we’ve been installing fences since 1983; working around utility lines is something we do regularly. A utility line doesn’t have to stop your project. It just means the installation needs to be planned carefully before anyone picks up a shovel.
Here’s what every homeowner should think about before fencing around utility lines:
Knowing these four things before your project begins is what separates a smooth installation from a costly, potentially dangerous mistake.
Even if you’ve lived at your property for years and think you have a general sense of where your utilities run, that assumption isn’t worth the risk. Being wrong by even a few feet can have serious consequences.
In Illinois, state law requires homeowners to have underground utilities marked before any digging project, regardless of depth or size. The way to do that is through JULIE (Joint Utility Locating Information for Excavators), which you can reach by calling 811. Here’s what that process looks like:
Skipping this process puts you at serious risk. If you dig without confirmed markings and strike a utility line, you could face injuries, costly repairs, and significant legal liability.
Locating your utilities is only the first part of the conversation. You also need to understand whether your planned fence sits within a utility easement, because that changes what you’re allowed to do.
A utility easement grants utility companies the legal right to access buried lines on your property for inspection, repairs, and maintenance. Even if the easement runs through your backyard, you cannot build a fence within it without written permission from every utility that holds the easement. There is also another risk to consider: if your fence blocks utility access, a utility company can order its removal at your expense, regardless of what it cost to install. This applies even if you received written permission, as utility companies can still require access years later.
You could get the fence exactly where you want it today, only to have it torn down later. That’s a conversation worth having with your fence contractor before installation begins.
Knowing where your utility lines are is a good start, but it does not tell you where to place your fence posts. That decision requires a second layer of planning.
The standard rule is straightforward: do not use power digging equipment within 18 inches of a marked utility line. Within that zone, hand tools are required, and every post hole must be dug by hand. For a full fence line, that adds up to significant extra time and labor. Your fence layout should account for utility markings before anyone decides where each post goes. Placing posts too close to a marked line results in more manual work, slower installation, and higher overall costs.
Once you know where the utilities are and how the fence will be laid out, material choice becomes part of the conversation, particularly near electrical lines. Not all fencing materials carry the same level of risk in these areas, so it’s worth thinking through your options before committing to a material.
Choosing vinyl or wood near a utility area doesn’t mean you can skip proper marking and safe digging. Those steps are still required no matter what material you choose. But if the presence of electrical lines is already on your mind, a non-conductive material is one fewer thing to worry about.
You can absolutely put up a fence near utility lines, as long as the planning happens before anyone starts digging. The problem is that most utility line incidents happen during DIY installations, simply because homeowners aren’t familiar with the process. We are.
