Even if you don’t make any changes to your property, many states only guarantee the accuracy of a land survey for five to ten years.

Depending on property size and complexity, usually 1-3 weeks.

A boundary survey measures the boundary lines of the property, only the length of each property line and their locations. A land survey includes a more in-depth measurement of the property, including the heights and depths of the terrain measured by a topographic survey.
