The Importance of Knowing Your Property Boundaries

Why Property Boundaries Matter More Than You Think

Most homeowners have a general sense of where their property ends and their neighbor's begins. But "general sense" is not the same as knowing your exact legal boundaries — and the difference can lead to expensive disputes, construction delays, and strained relationships with neighbors. Understanding your property boundaries is one of the most fundamental and often overlooked aspects of homeownership.

How to Find Your Property Survey

A property survey (also called a plot plan or boundary survey) is a document prepared by a licensed land surveyor that shows the exact dimensions and boundaries of your lot. If you purchased your home recently, a copy of the survey is likely in your closing documents. Lenders often require a survey as part of the mortgage process.

If you cannot find your survey in your closing documents, check with your local Registry of Deeds, where surveys are often recorded along with deeds and plot plans. Your town's assessor's office or engineering department may also have copies on file. In some cases, the previous owner or their attorney may have retained a copy.

If no survey exists or the existing one is outdated (for example, if the property was subdivided or structures have been added since the last survey), you can hire a licensed land surveyor to create a new one. This involves a physical inspection of the property, placement of boundary markers, and preparation of a formal survey document.

Common Boundary Disputes and How to Handle Them

Fence Encroachments

One of the most common boundary issues involves fences that are not located on the actual property line. A neighbor's fence may encroach onto your property by several inches or even feet. In some cases, a homeowner may discover that their own fence is on the neighbor's land. These situations can become contentious, especially when one party has been maintaining land they believed was theirs.

Structures Near Property Lines

Sheds, garages, additions, and decks built near property lines can create problems if they encroach on a neighbor's lot or violate setback requirements. Most municipalities have setback rules that require structures to be a minimum distance from property lines. Building within the setback without a variance can result in a requirement to remove the structure.

Trees and Landscaping

Trees that straddle property lines or have branches overhanging a neighbor's yard are a frequent source of disputes. In most jurisdictions, a property owner has the right to trim branches that extend over their property line, but the rules about trunk location, root damage, and tree removal vary by state and municipality.

Shared Driveways and Easements

Some properties have shared driveways or easements that grant one owner the right to cross another's land. These arrangements are typically documented in the property deed but are not always well understood by current owners. Disputes over shared driveway maintenance, parking, and access are common and can be complex to resolve.

When to Get a New Survey

You should consider commissioning a new property survey in several situations: before building a fence, shed, addition, or any structure near a boundary line; when a neighbor's construction appears to encroach on your property; if you are planning to sell your home and cannot locate the existing survey; if the property has been subdivided or altered since the last survey; or if you are involved in or anticipating a boundary dispute.

A residential survey typically costs between $400 and $1,000, depending on the size and complexity of the lot. While this may seem like an expense you would rather avoid, it is far less costly than the legal fees, construction delays, and relationship damage that can result from a boundary dispute.

Practical Steps for Homeowners

First, locate your existing survey or plot plan and familiarize yourself with your property lines. Walk your property and look for survey markers — these are typically iron pins or stone monuments set at the corners of your lot. If markers are missing or you cannot find your survey, consider hiring a surveyor.

Before starting any project near a property line — fencing, landscaping, construction — verify the exact boundary location. Do not rely on assumptions based on existing features like hedges, worn paths, or old fence lines. These features often do not align with legal boundaries.

If you discover or suspect a boundary issue, address it early. A friendly conversation with your neighbor is always the best starting point. Most encroachments are unintentional, and many can be resolved through mutual agreement. If informal resolution is not possible, a professional survey provides an objective basis for negotiation, and mediation is a cost-effective alternative to litigation.
