What percentage of the terminal is typically classified as non-rentable space?

The classification of non-rentable space in an airport terminal generally falls within the range of 10-15%. This percentage accounts for areas that are necessary for terminal operation but do not generate revenue through rental agreements. Such spaces may include restrooms, mechanical rooms, and passenger circulation areas. These areas serve essential functions that support the overall operations of the terminal, ensuring a safe and efficient environment for travelers, although they are not directly part of the commercial leasing aspects of the facility.

Understanding this classification is important for airport management and financial planning, as it helps to identify how much space within the terminal can be leveraged for revenue-generating activities versus what must be allocated for essential operational uses. Hence, the figure of 10-15% accurately reflects the typical proportion of non-rentable space in a terminal environment.
