What Is an Encroachment in Real Estate?

An encroachment occurs when a structure or improvement extends beyond a property's legal boundary onto another parcel.

Examples may include fences, driveways, garages, sheds, retaining walls, or other improvements that cross a property line.

Not every encroachment creates the same legal or practical concerns, but buyers should understand what exists before purchasing a property.

Why Can Encroachments Matter?

Encroachments may affect future renovations, financing, title insurance, or property transfers.

In some situations, an encroachment may require additional documentation, agreements between neighbors, or professional review.

The impact depends on the specific property and the nature of the encroachment.

How Can Buyers Identify Possible Encroachments?

A property survey is often one of the best ways to identify potential encroachments.

Buyers should also compare the survey with visible improvements on the property and discuss any questions with their attorney or survey professional before closing.

Does an Encroachment Affect Property Assessment?

An encroachment does not automatically change a property's assessment.

However, understanding the physical condition of the property is an important part of reviewing ownership records before making a purchase or preparing an assessment review.
