What is a Boundary Survey?
A boundary survey is a professional measurement and mapping of a property's legal boundaries. A licensed surveyor physically locates and marks the property corners and boundary lines based on the legal description in the deed. The resulting survey map shows the property's exact dimensions, area, and the location of structures, easements, and encroachments relative to the boundaries.
When you need a boundary survey
Property disputes: When neighbors disagree about where the property line falls.
New construction: To ensure structures comply with setback requirements.
Fence installation: To place fences on the correct side of the property line.
Property purchase: Some lenders and title companies require a survey, especially for larger properties or properties without recent surveys.
Lot splits: Required before dividing a parcel into separate lots.
What a boundary survey shows
Property corners (physically marked with iron pins, stakes, or monuments), boundary lines with distances and bearings, total property area, location of buildings relative to boundaries and setbacks, easements (utility, access, drainage), encroachments (structures crossing the boundary in either direction), and flood zone boundaries if applicable.
Cost and timeline
A boundary survey for a typical residential lot costs $500-$2,000. Larger parcels, difficult terrain, or properties with unclear legal descriptions cost more. Timeline: 1-4 weeks depending on surveyor availability and complexity.
For investors
Surveys protect against buying properties with encroachment issues, boundary disputes, or less land than represented. When buying acreage or properties where the land value is a significant component, a survey is particularly important. The cost is minimal compared to the potential loss from a boundary dispute after purchase.
