Who is defined as a person that acts as an agent of the owner and manages the use of a building?

The role defined as a person who acts as an agent of the owner and manages the use of a building is accurately represented by "Administrator." This person typically has the responsibility for overseeing various aspects of building management, including maintenance, tenant relations, and compliance with safety regulations.

An administrator serves as a bridge between the building owner and the operational needs of the facility, ensuring that the owner's interests are upheld while efficiently managing the daily activities within the building. This position requires a comprehensive understanding of property management, building operations, and the legal obligations that come with managing a real estate asset.

While "Manager" and "Operator" might seem similar, they usually focus more on specific aspects of building operations or management. A manager might handle day-to-day administrative tasks, whereas an operator is often involved in the physical workings of the building, such as facility maintenance. The distinction lies in the broader scope and agent-like role of an administrator, making them the most fitting answer for the defined role. The term "Owner" refers specifically to the property's titleholder, making it less appropriate in this context.
