Trophy vs. Class A vs. Class B vs. Class C Office Spaces

Differentiating office space classes is somewhat of an arbitrary and vague task in Manhattan.  However, here at HedgeFundSpaces.com, we are often asked by our hedge fund, investment bank, private equity and boutique financial clients “what are the differences between Trophy, Class A, Class B and Class C office buildings in New York City?”  Though it is not a simple question to answer, for comparison purposes New York City office buildings are grouped into four categories- Classes Trophy, A, B and C. Though the classification system is  subjective, a combination of factors including building standard finishes, mechanical system criteria, amenities, location, market perception, and base rent are used as the comparative guidelines.

Trophy Office Buildings in New York City

Trophy office buildings are the most prestigious towers within a certain submarket.  Assuming all of the characteristics of Class A office buildings, these towers command a premium due to cache, modernism, views, tenant roster and amenities.  They are the most expensive buildings per square foot and compete for the ultra-high-end tenants.  (Looking for Trophy office space in New York City?  Click here for our free and instant office space search.)

Class A Office Buildings in New York City

According to BOMA.org (Building Owners and Managers Association), Class A office buildings are highly regarded assets and compete for the premier tenants in a submarket.  More often than not, these assets achieve rents above average for their area. They have a very high quality standard of finishes, state of the art mechanical systems, exceptional accessibility and a definite market presence.  Most of these buildings are located on the actual avenue and not a side street.  (Looking for Class A office space in New York City?  Click here for our free and instant office space search.)

Class B Office Buildings in New York City

According to BOMA’s website, Class B office buildings often compete for a wide range of users.  These buildings tend to have competitive and reasonable rental rates. Building finishes are fair to good for the area and systems are adequate.  The majority of these buildings are mid-block and not located on the avenue- thus providing less natural light.  Accordingly, class B buildings do not compete with Class A at the same price.

Class C Office Buildings in New York City

Class C office buildings are assets that compete for tenants requiring solely functional office spaces, at rents below the average for the area. These buildings often have limited hours for access, unattended lobbies, minimal elevator access, outdated building systems and antiquated installations.
