Building classifications in most markets refer to Class "A", "B", "C" and sometimes "D" properties. While the rating assigned to a particular building is very subjective, Class "A" properties are typically newer buildings with superior construction and finish in excellent locations with easy access, attractive credit to tenants and which offer multitude of amenities to tenants. The class of a building may vary depending on the location of the property. What is a class B in one market might be a class C in a different market. Also, as the class of the building decreases (moves from A to B etc) the rents tend to decrease.
