How Do You Read a Property Survey: What Should You Look For?

Understanding the boundaries and features of a piece of property is essential for homeowners, buyers, and real estate professionals alike. A property survey is a crucial document that provides a detailed map of land boundaries, structures, and other important elements. But how do you read a property survey effectively? Knowing how to interpret this technical drawing can empower you to make informed decisions, avoid disputes, and fully grasp the scope of your land.

Reading a property survey might seem daunting at first, given the specialized symbols, measurements, and terminology it contains. However, with a basic understanding of its components and what they represent, the survey becomes a valuable tool rather than a confusing blueprint. It offers a visual and legal representation of your property, showing everything from boundary lines to easements and improvements.

Before diving into the specifics, it’s helpful to recognize the purpose and common elements of a property survey. This foundational knowledge will set the stage for a clearer, more confident interpretation of the document. Whether you’re verifying property lines or planning a new project, learning how to read a property survey is an essential skill that can save time, money, and headaches down the road.

Understanding Boundary Lines and Easements

One of the critical elements of a property survey is the clear depiction of boundary lines. These lines define the exact perimeter of the property, distinguishing it from neighboring parcels. Surveyors use precise measurements often derived from legal descriptions, physical markers, and historical records to establish these boundaries. When reading a survey, pay close attention to the following aspects:

Boundary lines are typically represented by solid or dashed lines surrounding the property.
Bearings and distances are noted along these lines, indicating direction (using degrees, minutes, and seconds) and length (usually in feet or meters).
Monuments or markers such as iron pins, concrete posts, or natural landmarks may be plotted at corners or along boundaries to provide physical reference points.

Easements are another important feature often shown on property surveys. An easement grants specific rights to another party to use a portion of the property for a particular purpose, such as utilities, access roads, or drainage. Easements do not transfer ownership but can affect how the landowner may use that section of the property. When analyzing easements on a survey, consider:

The type of easement (utility, access, conservation, etc.).
The location and dimensions of the easement area.
Any restrictions or notes about usage rights associated with the easement.

Interpreting Legal Descriptions and Survey Notes

Legal descriptions are a fundamental part of the survey that provide the formal identification of the property using specific language and references. These descriptions often reference government survey systems, subdivision plats, or metes and bounds measurements. Understanding these descriptions requires familiarity with certain terms and formats:

Metes and bounds: Describes the property boundaries using directions and distances, often starting from a known point of beginning (POB).
Lot and block: Refers to a specific lot within a recorded subdivision plat.
Public Land Survey System (PLSS): Uses townships, ranges, and sections to define property location in many parts of the United States.

Survey notes usually accompany the map and provide essential context about the methods used, datum references, surveyor certifications, and any anomalies or exceptions found during the survey. Important points to note include:

The datum and coordinate system used (e.g., NAD83, WGS84).
Any discrepancies or conflicts with previous surveys or records.
Certifications by the licensed surveyor, including their seal and signature.

Reading Symbols and Legend Information

Property surveys use a standardized set of symbols to represent various features such as buildings, fences, utilities, vegetation, and water bodies. To accurately interpret these symbols, always refer to the legend typically included on the survey map. Common symbols include:

Squares or rectangles for structures like houses or sheds.
Lines with specific patterns for fences, walls, or roads.
Circles or crosses to mark trees, utility poles, or wells.
Shaded or hatched areas indicating easements, flood zones, or right-of-ways.

Below is a sample table summarizing typical symbols and their meanings on a property survey:

Symbol	Representation	Description
●	Utility Pole	Marks the location of power or telephone poles
— — —	Fence Line	Represents boundary fences or barriers
▭	Building	Indicates structures such as houses or garages
/////	Easement Area	Hatched area showing easement boundaries
▲	Survey Monument	Physical markers used to denote key survey points

By familiarizing yourself with these symbols and the accompanying legend, you can accurately interpret all the elements shown on the survey and understand the property’s physical and legal layout.

Measuring Distances and Angles on the Survey

Survey maps provide scaled representations of the property, meaning that all features are drawn proportionally but reduced in size. To read distances and angles:

Identify the scale of the map, often noted as a ratio (e.g., 1 inch = 20 feet).
Use a ruler or scale bar on the map to convert measurements from the drawing to actual ground distances.
Bearings or angles are typically given in degrees, minutes, and seconds, describing the direction of boundary lines relative to a reference direction such as true north or magnetic north.

Understanding these measurements is crucial for identifying property limits, setbacks, and potential encroachments. Always cross-reference the numerical data with the visual representation to ensure consistency.

Recognizing Improvements and Restrictions

Surveys often identify improvements on the property, which include all permanent structures, landscaping features, and utility installations. These details help determine if any encroachments exist or if the current use complies with zoning and building regulations. Common improvements shown include:

Buildings and accessory structures
Driveways and sidewalks
Fences and retaining walls
Wells and septic systems
Utility lines and meters

Restrictions related to the property, such as setback lines, flood zones, or conservation areas, will also be marked. These indicate where certain activities or constructions are prohibited or limited. They are crucial for planning future developments or renovations.

By carefully analyzing these features on the survey, property owners and buyers can make informed decisions regarding use, maintenance, and potential modifications.

Understanding the Basic Components of a Property Survey

A property survey is a detailed map or drawing that delineates the boundaries and features of a parcel of land. To accurately read a property survey, it is essential to first understand its fundamental elements.

The key components include:

Property Boundaries: These are the lines that define the perimeter of the property, often marked with solid or dashed lines and labeled with dimensions.
Monuments and Markers: Physical markers such as stakes, iron rods, or concrete monuments placed at boundary corners to indicate exact points on the ground.
Easements and Rights-of-Way: Areas within or adjacent to the property where others have legal access or use rights. These are typically highlighted and labeled.
Improvements: Structures or modifications on the property, including buildings, fences, driveways, and utility lines.
Scale and Legend: The scale translates the drawing’s measurements to real-world dimensions, while the legend explains the symbols and abbreviations used in the survey.
Legal Description: A written description of the property boundaries, often referencing metes and bounds, lot numbers, or subdivision plats.

Recognizing these components is crucial for interpreting the survey accurately and understanding the legal extent and limitations of the property.

Interpreting Boundary Lines and Dimensions

Boundary lines on a survey represent the legal limits of the property. These lines are usually drawn as solid or dashed lines and are annotated with precise measurements.

Element	Description	Common Notations
Boundary Lines	Lines that define the edges of the property	Solid or dashed lines, often labeled with length in feet
Dimensions	Measurements of boundary lines	Numbers indicating linear feet, e.g., “150.00′”
Bearing	Directional angle of a boundary line relative to north	Notation such as N 45° 30′ E
Corner Markers	Physical or surveyed points marking boundary corners	Symbols like a circle, cross, or labeled monuments (e.g., “IP” for iron pipe)

Bearings indicate the direction of a boundary line relative to true north or magnetic north and are crucial for locating the property precisely. Dimensions quantify the length of each boundary segment.

Identifying Easements, Setbacks, and Restrictions

Easements, setbacks, and other restrictions on a property survey inform about limitations on land use or access rights.

Easements: These are rights granted to others to use a portion of your property for a specific purpose, such as utility access or shared driveways. Easements are typically shaded or crosshatched and labeled accordingly.
Setbacks: Minimum required distances between structures and property boundaries, often mandated by local zoning laws. Setback lines are shown as dashed lines parallel to property boundaries and are labeled with the setback distance.
Restrictions: Additional limitations may be noted on the survey or in accompanying documents, such as flood zones, conservation areas, or historical preservation requirements.

Understanding these features is vital to avoid encroachment issues and to ensure compliance with legal and municipal regulations.

Reading the Legend and Symbols on a Property Survey

The legend is a key component of any property survey, providing explanations for the symbols and abbreviations used throughout the document.

Symbol	Meaning
● or ○	Surveyed corner or monument
IP	Iron Pipe, a common corner marker
R/W	Right-of-Way
UE	Utility Easement
Setback Lines	Dashed lines indicating required distances from boundaries
Contour Lines	Lines showing elevation changes (topography)

Familiarity with these symbols allows for quicker interpretation of the survey and helps in identifying property features and constraints at a glance.

Utilizing the Legal Description for Precise Property Identification

The legal description complements the graphical survey by providing a textual delineation of the property boundaries, often using metes and bounds or referencing subdivision plats.

Metes and Bounds: Describes the property perimeter by listing sequential boundary lines
