* Landlords charge Tenants based on the number of Rentable Square Feet ("RSF") leased. The RSF calculation starts as a total of the Usable Square Footage ("USF"), the dimensions of the actual spaces. To this USF is added a Circulation Factor, typically 35% - 40%, which is essentially the space allowing movement between the individual rooms/spaces. Landlords then add to this number a Common Area Factor ("CAF"), typically about 15%, to account for those areas shared by all tenants in a multi-tenant building (lobby, restrooms, shared hallways, etc.).
