Which area measurement includes restrooms and janitor closets?

The measurement that includes restrooms and janitor closets is best defined as rentable area. Rentable area encompasses all spaces that can be rented out to tenants, which means it includes not only the usable space within a tenant's leased area but also the additional spaces such as restrooms and janitor closets that are available for tenant use but not fully utilized for productive or operational purposes by the occupant.

In commercial leasing, this is especially important because the rentable area is typically what determines the size of the area for which tenants will be paying rent. It provides a clearer and more comprehensive understanding of what a tenant is actually receiving in terms of space, which can affect their occupancy costs and decisions.

The other options, such as usable area, refer strictly to the areas that the tenant can use exclusively, thereby excluding shared spaces like restrooms or janitor closets. Common area usually describes spaces used by all tenants in a building, such as lobbies or hallways, but it doesn’t specifically designate what is included in rent calculations. Exempt area typically refers to areas that are not chargeable for rent, further clarifying the delineation that makes rentable area the most accurate choice in this context.
