What is the prorated share of using the common area referred to in terms of usable foot?

The prorated share of using the common area in a commercial or office building is typically calculated based on the rentable square footage, which includes both the usable space and the proportionate share of the common areas. When referring to the common area, the calculation usually involves the total rentable square footage of a tenant's space plus a factor to account for the common areas.

In this context, "Rentable ft + 2" indicates that the calculation for a tenant’s share of common areas is based on their rentable square footage plus an additional space factor, which accounts for the shared spaces—such as lobbies, restrooms, and hallways. This extra component ensures that tenants appropriately contribute to and benefit from the shared facilities.

Understanding this calculation is crucial for tenants in order to accurately assess lease terms regarding their financial obligations related to shared spaces. In many commercial leases, tenants are often responsible for a proportionate share of common area maintenance costs, and these calculations help to determine that share comprehensively.
