When buying a home in Montgomery County, Maryland, most people focus on the asking price, square footage, condition, and location.
But there’s another important question worth asking before settlement:
Where does the property legally begin and end?
I’m Jeremy Rosenthal, a REALTOR® serving Maryland, Virginia, and Washington, DC.
Whether you’re purchasing a single-family home in Rockville, a townhouse in Gaithersburg, or a property in Bethesda, understanding property boundaries can help you make a more informed decision.
A fence, driveway, or landscaped area may appear to mark a property line, but appearances don’t always establish legal ownership.
Here’s what buyers should understand.
What Is a Property Survey?
A property survey is a professional assessment of land boundaries and, depending on the survey’s scope, improvements and other property features.
Licensed surveyors use measurements, recorded documents, and physical evidence to identify or establish relevant boundaries.
Different types of surveys serve different purposes.
For example, a residential location drawing may show the approximate position of a home and other improvements relative to recorded property lines.
A detailed boundary survey may be needed when precise boundary locations are important.
Buyers should understand which type of survey is available and what information it provides.
Why Do Property Boundaries Matter?
Montgomery County includes properties with different lot sizes, layouts, and development histories.
In Rockville, Gaithersburg, Bethesda, and surrounding communities, boundary information can be important when evaluating existing structures or planning improvements.
For example, a buyer might want to install a fence, expand a patio, construct an addition, or build a detached structure.
Before moving forward, the buyer may need to understand where the legal boundaries are and whether restrictions affect the proposed project.
Identifying these questions before settlement can help avoid surprises later.
Does a Fence Mark the Legal Property Line?
Not necessarily.
A fence may have been installed inside a property’s boundary, along an agreed location, or somewhere that does not match the recorded property line.
Sometimes fences have been in place for decades.
Their location alone does not prove ownership of the land.
If the precise boundary is important, buyers should consult a licensed surveyor rather than relying on visible features.
What About Driveways and Landscaping?
The same principle applies.
A driveway, retaining wall, garden, or landscaped area may not correspond exactly with the legal property boundaries.
Buyers should avoid assuming that every visible improvement is located entirely within the parcel being purchased.
What Is an Easement?
An easement generally grants another party certain rights to use land for a particular purpose.
Common examples include utility easements and access easements.
A utility easement may allow a service provider to maintain infrastructure located on private property.
An access easement may provide a legally established route across a parcel.
Easements can influence where improvements may be constructed and how portions of the property may be used.
The exact rights and limitations depend on the recorded documents and applicable law.
Can Easements Affect Home Improvements?
Yes.
Imagine purchasing a home in Gaithersburg with plans to install a detached shed or extend a fence.
Before beginning construction, you may need to determine whether the proposed location overlaps an easement.
You may also need to review local zoning requirements, permits, setbacks, and homeowners association rules.
A project that appears physically possible may require additional approvals or changes to the design.
Understanding these restrictions early can help buyers plan more effectively.
Where Can You Research Montgomery County Property Records?
Several public resources can help buyers begin their research.
Maryland State Department of Assessments and Taxation
Maryland SDAT provides property assessment information, including certain ownership details and property characteristics.
However, assessment records should not be treated as a precise boundary survey.
Maryland Land Records
Maryland Land Records provides access to recorded deeds and other property-related documents.
These records may help buyers research ownership history and recorded property interests.
Montgomery Planning
Montgomery Planning provides mapping and planning resources, including access to certain subdivision and parcel information.
These resources can help buyers identify documents worth reviewing.
Online maps and records are useful research tools, but they may not establish precise legal boundaries.
What Is an Encroachment?
An encroachment generally involves an improvement extending onto land owned by another party or into an area where the improvement may not be permitted.
Examples can include fences, driveways, retaining walls, and portions of buildings.
An apparent overlap does not automatically establish a legal encroachment.
The actual boundaries and property rights must be evaluated.
If concerns arise, buyers should consult qualified surveying, title, or legal professionals.
Is a Property Survey Required When Buying in Maryland?
Survey requirements vary depending on the transaction, lender, title insurer, and other circumstances.
Not every purchase requires the same type of survey.
A location drawing may be requested during the financing or title process.
However, a location drawing may not be sufficient to resolve a boundary dispute or determine exactly where a new structure can be installed.
Buyers should ask what documentation is being provided and whether additional surveying is appropriate.
Can Property Boundaries Affect Home Value?
Potentially.
A property’s usable land, legal access, and development restrictions can influence how buyers evaluate it.
For example, a buyer planning a future addition may place particular importance on setbacks and available buildable space.
Another buyer may have no plans to modify the property.
The effect on value depends on the specific property, its limitations, and current market conditions.
What Should Buyers Ask Before Settlement?
Consider asking these questions:
- Is a survey or location drawing available?
- What type of survey was completed?
- Are there recorded easements?
- Are there known boundary disputes?
- Do existing fences or structures raise questions?
- Are there HOA or municipal restrictions affecting planned improvements?
- Would an additional boundary survey be appropriate?
These questions can help identify concerns that deserve further investigation.
Frequently Asked Questions
Is a fence the legal property boundary?
Not necessarily. A fence’s location may differ from the recorded property line.
Can I find property lines on Google Maps?
Online maps can provide general location information, but they should not be relied upon to establish precise legal boundaries.
What is the difference between a location drawing and a boundary survey?
A location drawing generally serves a more limited purpose. A boundary survey involves more detailed work to establish or document property boundaries.
Can I build a fence over an easement?
That depends on the easement terms, applicable regulations, and required approvals.
Should I get a survey before purchasing a home?
It depends on the transaction and your intended use of the property. A qualified surveyor or title professional can help determine what is appropriate.
