Office Space , Commercial Real Estate

Class A, B, or C? Understanding Office Space Types

By The Keyser Editorial Team
October 09, 2025

In commercial real estate, office buildings are often grouped into broad categories known as office space classifications: Class A, Class B, and Class C. These classifications are not legal definitions but widely used industry terms that help describe the quality, condition, amenities, and location of a building.

Class A Office Space

Class A buildings are typically considered the top tier of the market. They are often newer construction or recently renovated properties in prominent business districts. Class A offices feature modern systems, high-quality finishes, professional management, and notable architectural design.

Class B Office Space

Class B buildings represent the mid-range of office space classifications. These properties may be slightly older or located outside prime corridors, but they remain functional, professional, and well-maintained. Many organizations view Class B offices as practical options, and with upgrades, some can compete with Class A space in certain markets.

 

Class C Office Space

Class C buildings are generally the most dated properties. They tend to lack modern systems, may require renovation, or be located in less central areas. Class C offices often attract cost-conscious users or those with specialized space needs.

Why Classifications Exist

While the classifications are useful for comparison, they are not uniform standards. Perceptions of whether a building is Class A, B, or C can differ between markets and even among real estate professionals.

Conclusion

The terms Class A, B, and C serve as a framework for understanding the relative positioning of office properties. These categories help convey general expectations about building quality and location within the commercial real estate market.
