If you’re facing a neighbor dispute, planning to install a fence, or getting ready to buy or sell property, getting a boundary survey in Boston, MA might be one of the smartest decisions you make. In dense neighborhoods like Dorchester, Roxbury, or Brighton — where homes sit close together — even minor property line misunderstandings can turn into major issues. A boundary survey brings clarity, protects your rights, and helps you avoid costly legal trouble.

What Is a Boundary Survey?
A boundary survey is a type of land survey that identifies the exact legal borders of your property. It involves a licensed surveyor reviewing your deed, using historical records, and performing precise on-site measurements. The goal is to mark and record where your land begins and ends, and where your neighbor’s land does too.
Why Property Line Disputes Are Common in Boston
In a city as old and densely developed as Boston, it’s no surprise that property boundaries can get confusing. Here’s why:
1. Narrow Lots and Historic Layouts
Many properties in areas like Beacon Hill and South End were laid out centuries ago, and their boundaries were defined before modern zoning laws and measurement techniques. For example, a property owner in Beacon Hill discovered that a stone wall, which had been in place for over 100 years, actually extended a few inches into their neighbor’s land. The discrepancy was due to outdated records, which a boundary survey helped to resolve. By identifying the correct boundary, the issue was addressed before it caused any potential legal conflict.
2. Shared Driveways and Fences
In neighborhoods like South Boston, where properties are closely packed, shared driveways and fences can lead to confusion about property lines. In one case, two homeowners believed the shared driveway on their property was entirely within their own lot. After conducting a boundary survey, it was revealed that the driveway extended onto both properties, clearly defining the shared space. A professional boundary survey helped prevent future conflicts and clarified each party’s responsibilities, avoiding costly disputes.
3. Inherited Property or Old Deeds
In Dorchester, a family inherited a property from several generations ago, but the deed was not updated to reflect the actual property layout. The inherited deed was at odds with the current layout, leading to confusion about property lines. After a boundary survey was conducted, discrepancies were uncovered, and the exact boundaries of the land were established. This cleared up any potential encroachment issues and helped avoid legal complications when it was time to subdivide or sell the land.
How a Boundary Survey Can Help
Here’s how a boundary survey in Boston, MA, can solve real-world problems:
- Prevent Legal Disputes
If you or your neighbor build on the wrong side of the line — even by a few inches — you could face legal action. A survey gives you solid proof of where the boundary is, which can settle arguments before they escalate. - Support Permits and Construction
If you’re planning an addition, building a fence, or doing any work near your property edge, the city may require proof of your boundary. Areas like West Roxbury and Roslindale often have strict permitting processes that require a current survey. - Help with Buying or Selling a Home
Buyers want to know exactly what they’re getting. Sellers don’t want a deal falling through because of a line dispute. A recent boundary survey builds confidence on both sides of the transaction — especially in high-value markets like Beacon Hill and Back Bay. - Avoid Surprises with Utilities and Easements
Surveys can uncover utility easements (such as underground pipes or power lines) that run through your land. Knowing this early prevents future headaches if you’re planning to dig or build.
When Should You Get a Boundary Survey?
You don’t need to wait for a conflict to act. Here are some smart times to order a boundary survey:
- Before installing a fence or retaining wall
- When buying or selling property
- Before subdividing a lot
- During land development or site planning
