The Building Owners and Managers Association (BOMA) classifies office space into three categories: Class A, Class B, and Class C. According to BOMA, Class A office buildings have the "most prestigious buildings competing for premier office users with rents above average for the area". BOMA states that Class A facilities have "high quality standard finishes, state of the art systems, exceptional accessibility and a definite market presence". BOMA describes Class B office buildings as those that compete "for a wide range of users with rents in the average range for the area". BOMA states that Class B buildings have "adequate systems" and finishes that "are fair to good for the area", but that the buildings do not compete with Class A buildings for the same prices. According to BOMA Class C buildings are aimed towards "tenants requiring functional space at rents below the average for the area". The lack of specifics allows considerable room for "fudging" the boundaries of the categories.
