About Property Boundaries

Land Surveyor

This information is intended to assist you in locating your property lines. All information is general in nature and should not be considered as legal advice or a substitute for a survey. A property line dispute is a legal issue between property owners. The City can assist you in providing information with your property lines adjacent to City property, easements and right of ways. The City does not resolve private property issues. Contact a Registered Maryland Land Surveyor for professional assistance in locating your property line and/or an attorney for legal advice. 

Your House Location Survey and Property Lines

When buying a home in Maryland, part of the process includes receiving a house location survey which will contain information regarding the boundary lines of your property. Finding physical evidence of your property lines can be difficult but with the help of a registered land surveyor, who can use specialized equipment, locating the property markers can be done easily and accurately.

The City does not locate private property boundaries for residents unless the property is adjacent to City property, easements and right of ways.

City or Park Property

Properties that border City property, parks, right-of-ways, easements or other government land can present a challenge in determining your property boundary. It is not acceptable for a homeowner to extend fences, build structures or encroach upon adjacent undeveloped park land or right of ways. This can lead to serious consequences to the homeowner including fines, cost for removal of the structure(s) and lawsuits. Park boundary surveys are available, upon request, through the Parks and Open Space Division. Please call 240-314-8704 for more information.

City Right-of-Way

City right-of-ways (ROW) typically refers to the common boundary of your front and / or side yard that borders a City street. The City is responsible for the sidewalks, utilities and street trees that fall within this right-of-way area. Right-of-ways are typically standard widths ( 40' 50', 60', etc.) with 50' being most common in a residential neighborhood.

Determining Your Property Line

To accurately determine a property’s boundaries, it is best to hire a land surveyor. A survey by a Registered Maryland Land Surveyor can locate existing boundaries or set new property markers. The location of the property markers is usually shown on your subdivision plat. Subdivision plats of properties in Rockville are available for review or purchase in the Public Works Department at City Hall. Plats also are available through the Maryland Land Recordswebsite. Property markers typically are not exposed and are found several inches below the surface. Land surveyors can locate the property markers in the field with a specialized metal detector.

House location surveys are available in the Community Planning and Development Services Department, 2nd Floor, City Hall, 111 Maryland Avenue, Rockville, MD 20850.

For more information, please call 240-314-8704.
