When examining a survey, which aspect does not concern the title agent?

The correct choice reflects that the title agent focuses primarily on aspects of property rights, boundaries, and legal encumbrances rather than the specifics of the property's type of construction. When examining a survey, the title agent evaluates property boundaries to determine the exact limits of ownership, ensuring there are no overlaps or disputes with neighboring properties. They also examine existing easements because these can affect the rights of the property owner and may impose restrictions on how the property can be used. Zoning classifications are important as they relate to how the property can be utilized in compliance with local regulations, which can impact the property's value and its suitability for the intended purpose.

In contrast, the type of construction pertains more to the physical characteristics of the building itself rather than the legal aspects of ownership and property rights the title agent is concerned with. This detail is more relevant for builders, real estate agents, or appraisers rather than a title agent conducting a title examination.
