What type of survey shows the location, size, and shape of improvements on a property?

The type of survey that shows the location, size, and shape of improvements on a property is a spot survey. A spot survey is specifically designed to provide a clear representation of the physical features of a property, including structures such as buildings, driveways, fences, and other improvements. This survey not only highlights the dimensions of these improvements but also indicates their positioning relative to property boundaries and other significant landmarks.

In contrast, a topographical survey focuses on the contours and elevations of the land, mapping the terrain's features rather than the improvements on it. A boundary survey identifies and establishes property lines but does not typically convey information about the structures. A physical survey is a less commonly used term that can refer to a variety of assessments, including looking at the condition of the physical improvements, but it doesn’t specifically focus on the spatial aspects as a spot survey does. Thus, the spot survey is the most appropriate choice for detailing the size and layout of improvements on a property.
