How Do You Read and Understand a Survey of Property?

Understanding how to read a survey of property is an essential skill for anyone involved in real estate, whether you’re a prospective buyer, a homeowner, or a professional in the field. Property surveys provide a detailed map of land boundaries, structures, and important features, serving as a critical tool to clarify ownership and avoid disputes. Yet, the technical language and symbols used in these documents can often seem daunting at first glance.

A property survey is much more than just a piece of paper with lines and measurements. It tells a story about the land, revealing its exact dimensions, the placement of buildings, easements, and sometimes even hidden encroachments. Learning to interpret these elements empowers you to make informed decisions, ensuring you fully understand what you’re buying or managing.

This article will guide you through the basics of reading a property survey, helping you to decode the jargon and symbols commonly found in these reports. By gaining a clearer understanding of how to read a survey of property, you’ll be better equipped to navigate the complexities of land ownership with confidence and clarity.

Understanding Boundaries and Easements

A critical aspect of reading a property survey is identifying the boundaries and any easements that may affect the property. Boundaries are typically marked by lines on the survey, often accompanied by measurements and compass directions indicating the property’s perimeter. These lines connect points called monuments or markers, which can be physical objects such as iron rods, concrete markers, or natural landmarks.

Easements, on the other hand, represent rights granted to others to use a portion of the property for specific purposes. Common easements include utility lines, access roads, or drainage. Easements are usually indicated on the survey with dashed lines or distinct notations and are often labeled clearly.

When reviewing boundaries and easements, keep the following in mind:

Verify that boundary lines match the legal description found in the deed.
Identify any encroachments where structures or improvements may cross property lines.
Check for easements that could limit your use of the property or require access by others.
Note any right-of-way areas that provide access for utilities or neighboring properties.

Interpreting Survey Symbols and Notations

Survey maps use a variety of symbols and abbreviations to convey detailed information succinctly. Understanding these symbols is essential for accurately interpreting the survey.

Common symbols include:

Monuments or markers: Small circles, crosses, or squares often represent physical markers set by the surveyor.
Fence lines: Dashed or solid lines may indicate fences or walls.
Buildings: Rectangles or irregular polygons denote structures.
Topographic features: Contour lines show elevation changes, streams are often depicted with wavy lines.
Easement lines: Typically dashed or dotted lines with labels such as “Utility Easement” or “Access Easement.”

Surveys usually feature a legend or key that explains these symbols. Always consult this section to ensure accurate interpretation.

Reading Measurements and Directions

Surveys provide precise measurements and directional information to define the property’s shape and size. These are usually presented along boundary lines and can include:

Distances: Shown in feet or meters, indicating the length of each boundary segment.
Bearings or Azimuths: Compass directions expressed in degrees, minutes, and seconds, specifying the orientation of boundary lines relative to north.

For example, a boundary line may be described as “N 45° 30′ 00″ E 150.00 ft,” meaning the line runs 150 feet in a direction 45 degrees and 30 minutes east of due north.

To interpret these measurements correctly:

Identify the starting point or reference monument.
Follow the sequence of bearings and distances to visualize the perimeter.
Use a protractor or digital mapping tool if needed to translate bearings into angles on a map.

Reviewing Property Descriptions and Legal References

Property surveys often include detailed written descriptions known as “metes and bounds” or other legal notations that correspond to the visual map.

Key elements to look for include:

Metes and Bounds: A narrative description that outlines the property boundaries using landmarks, compass directions, and distances.
Lot and Block Numbers: References to recorded plats or subdivision maps.
Deed References: Information about recorded deeds or previous surveys that establish the legal context.
Surveyor’s Certification: A signed statement by the surveyor affirming the accuracy of the survey.

These descriptions help verify that the survey matches the official property records and can clarify any discrepancies.

Common Survey Terminology and Their Meanings

Familiarity with standard survey terms enhances comprehension. Below is a table of frequently encountered terms and their definitions:

Term	Definition
Benchmark	A fixed reference point of known elevation used in surveying.
Corner Monument	A physical marker placed at the property corner to indicate boundary points.
Easement	A legal right to use another’s land for a specific purpose.
Right-of-Way (ROW)	A type of easement allowing passage through property, often for roads or utilities.
Metes and Bounds	A method of describing land by detailing directions and distances along boundaries.
Plat	A detailed map showing divisions of land, including lots and streets.

Understanding these terms will help you navigate the technical language commonly found in property surveys.

Understanding the Components of a Property Survey

A property survey is a detailed map and legal document that outlines the boundaries, features, and dimensions of a parcel of land. To read a survey effectively, it is essential to become familiar with its primary components:

Boundary Lines: These are the lines that define the perimeter of the property. They are usually marked with solid or dashed lines and often include measurements.
Monuments and Markers: Physical markers such as stakes, pins, or concrete monuments placed on the ground to indicate boundary corners.
Easements and Rights-of-Way: Areas where others have legal access or use rights, often shown with dashed lines or shading.
Improvements: Structures on the property such as buildings, fences, driveways, and utilities.
Topographical Features: Natural features like trees, streams, slopes, or wetlands, sometimes included depending on the survey type.
Legal Descriptions: Written descriptions of the property boundaries using metes and bounds, lot and block, or rectangular survey systems.

Interpreting Boundary Lines and Measurements

The boundary lines on a survey define the exact limits of ownership. Understanding how to read these lines is fundamental:

Line Types: Solid lines generally represent the property boundary, while dotted or dashed lines may indicate easements or setback lines.
Measurements: Distances between points are given in feet or meters. These measurements correspond to the actual lengths of each boundary segment.
Bearings and Directions: Bearings use compass directions (e.g., N 45° E) to describe the orientation of boundary lines.
Corners and Angles: Each corner is typically marked with a monument and has an angle measurement that defines how the boundary changes direction.

Element	Description	Example
Boundary line	Defines the property perimeter	Solid black line
Distance measurement	Length of boundary segment	150.00 feet
Bearing	Direction relative to north	N 30° 15′ 00″ E
Corner monument	Physical marker of boundary corner	Iron pin, concrete post

Recognizing Easements and Rights-of-Way

Easements and rights-of-way are legal allowances permitting others to use a portion of the property for specific purposes. These are critical to identify, as they can limit property use.

Types of Easements: Utility easements, access easements, drainage easements.
Representation on Survey: Often shown as dashed or dotted lines with labels specifying the easement type.
Impact on Property Use: Easements may restrict building or fencing within their area.
Legal References: Easements are usually referenced by document number or recorded plat.

Deciphering Legal Descriptions

Legal descriptions provide a textual explanation of property boundaries, supplementing the graphical map.

Metes and Bounds: Uses physical landmarks and directions to describe boundaries (e.g., “From the old oak tree, north 100 feet to the stone wall”).
Lot and Block: Refers to subdivision plats with numbered lots and blocks.
Rectangular Survey System: Uses township and range coordinates primarily in certain U.S. states.
Cross-Referencing: Always compare the legal description with the survey map to ensure consistency.

Evaluating Improvements and Encroachments

Surveys often indicate structures and improvements on or near the property lines, which can affect ownership rights.

Improvements Included: Buildings, fences, driveways, pools, and utilities.
Encroachments: Structures or improvements that extend beyond the property boundary onto neighboring land.
Surveyor’s Notes: Look for annotations or symbols indicating encroachments or potential boundary disputes.
Implications: Encroachments may require legal resolution or affect property value.

Utilizing the Surveyor’s Certification and Notes

The surveyor’s certification validates the accuracy and reliability of the survey. It includes:

Date of Survey: Indicates when the survey was conducted.
Surveyor’s Seal and Signature: Professional certification by a licensed surveyor.
Scope and Limitations: Notes on what was surveyed and any exclusions or conditions.
References to Previous Surveys: Mentions prior surveys or recorded plats used.
Special Instructions: Any recommendations or warnings about property conditions.

Practical Tips for Reading a Property Survey

Always use a scale ruler to measure distances on the survey if dimensions are not explicitly given.
Compare the survey with the deed and title documents to confirm boundary descriptions.
Identify all legends and symbols; they provide key information for interpretation.
Pay attention to the scale and orientation, usually indicated by a north arrow.
Consult a licensed surveyor or real estate attorney if any part of the survey is unclear or if potential boundary issues arise.
Use the survey as a tool for property development, purchase, or dispute resolution by understanding its detailed information.
