Which class of office building is known for providing functional space at below-average rents?

Class C office buildings are characterized by their lower quality and often older construction, making them more affordable for tenants. These buildings typically offer functional space that meets basic needs but may lack the premium amenities, aesthetics, or prime location found in higher-class buildings. As a result, they tend to attract tenants looking for cost-effective options, which is why they are associated with below-average rents. Class C buildings can also be a good choice for startups or businesses that prioritize budget over prestige.

In contrast, Class A buildings are top-tier properties that boast high-quality construction, prime locations, and appealing amenities, typically commanding higher rental prices. Class B buildings serve as a middle ground, offering decent quality and amenities at moderate rents. Class D buildings, while not commonly referenced in this context, usually refer to very low-quality properties that may require significant renovations or updates and typically attract very low rents as well.

Hence, Class C is accurately recognized for its balance of functionality and affordability.
