When Should You Add a Sewer Scope to Your Chicago Home Inspection?

Buying a home in Chicago comes with a long checklist, but one item many buyers overlook is the sewer scope. While a standard home inspection evaluates visible systems inside the home, it does not show what is happening underground. In a city with aging infrastructure, adding a sewer scope can help you avoid costly surprises after closing.

What Is a Sewer Scope Inspection?

A sewer scope inspection uses a specialized camera to inspect the main sewer line running from the home to the city connection. This line is not visible during a typical home inspection, yet it plays a critical role in protecting the property from backups and water damage.

When Is a Sewer Scope Especially Important in Chicago?

A sewer scope is highly recommended in several common Chicago scenarios:

• Older homes: Many Chicago homes were built before modern sewer materials were standard. Clay, cast iron, and Orangeburg pipes are more prone to cracking, corrosion, and collapse.

• Large or mature trees: Tree roots naturally seek moisture and often infiltrate sewer lines, leading to blockages or breaks.

• Homes with a history of backups: Slow drains or past sewer issues are strong indicators that further inspection is needed.

• Before purchasing a flipped property: Renovations often focus on cosmetic upgrades while underground systems remain untouched.

• Prior to the end of your inspection contingency period: Identifying sewer issues early gives you leverage to negotiate repairs or pricing.

Why a Sewer Scope Can Save You Money

Sewer line repairs in Chicago can easily cost thousands of dollars, especially if excavation or street permits are required. A sewer scope provides documentation of the pipe’s condition, allowing buyers to make informed decisions. In many cases, findings can be used to request repairs or credits from the seller.

Chicago’s sewer infrastructure is managed by the City of Chicago Department of Water Management, which oversees connections and regulations that homeowners must follow. Understanding the condition of your private sewer line helps prevent compliance issues down the road.

For broader guidance on wastewater systems and household sewer responsibilities, the U.S. Environmental Protection Agency offers helpful resources on how sewer systems function and why maintenance matters.

The Bottom Line

If you are buying a home in Chicago, especially an older one, a sewer scope is not an upgrade, it is a smart risk-management tool. Adding it to your home inspection can provide peace of mind and protect you from unexpected, expensive repairs after move-in.
