Primer: Differentiating Class A, B, and C Office Space
Directory 2013
Class A
These buildings represent the newest and highest quality buildings in their market. They are generally the best looking buildings with the best construction, and possess high-quality building infrastructure. Class A buildings also are well located, have good access, and are professionally managed. As a result of this, they attract the highest quality tenants and also command the highest rents.
Class B
This is the next notch down. Class B buildings are generally a little older, but still have good quality management and tenants. Oftentimes, value-added investors target these buildings as investments since well-located Class B buildings can be returned to their Class A glory through renovations such as facade and common area improvements. Class B buildings should generally not be functionally obsolete and should be well maintained.
Class C
The lowest classification of office building and space is Class C. These are older buildings and are located in less desirable areas and are often in need of extensive renovation. Architecturally, these buildings are the least desirable, and building infrastructure and technology is outdated. As a result, Class C buildings have the lowest rental rates, take the longest time to lease, and are often targeted as re-development opportunities.
The above is just a general guideline of building classifications. No formal standard exists for classifying a building. Buildings must be viewed in the context of their sub-market; i.e., a Class A building in one neighborhood may not be a Class A building in another.
