Which of the following is classified as a Business occupancy?

A business occupancy classification typically includes spaces that are used for the transaction of business or the conduct of services. Office buildings fit this description as they are primarily designed for administrative and professional services, accommodating various business activities such as meetings, customer interactions, and employee operations. This classification is important in building codes as it influences safety, accessibility, and zoning regulations.

In contrast, hospitals are classified under a different occupancy type due to the healthcare services they provide, which require specific safety measures and protocols. Restrooms are considered accessory spaces rather than primary occupancy types. Lunch and break rooms, although enabling business functions, are supportive areas that don't encompass the full scope of business operations like office buildings do. Thus, office buildings are the clear choice for business occupancy classification.
