When evaluating a property, what additional factor must the appraiser consider regarding its environmental impact?

The correct answer focuses on the presence of endangered species because it directly relates to environmental impact assessments that appraisers must consider when evaluating a property. The presence of endangered species can influence not only the value of a property but also its development potential and the requirements related to land use and conservation.

If a property is found to contain habitats crucial for endangered species, there may be legal restrictions on development or alterations to the land, which can significantly impact the property's marketability and usability. This consideration is important because it can lead to additional costs for the developer and potentially affect the community’s environmental health.

In contrast, historical significance, building code compliance, and potential zoning changes, while also relevant to property evaluations, do not directly tie into the environmental impact in the same way as the presence of endangered species. Historical significance pertains more to cultural value, building codes are primarily about safety and construction standards, and potential zoning changes relate to future use rather than current environmental concerns.
