The total square footage used to calculate a tenant's rent. It includes the tenant's private usable space plus a proportionate share of common areas like lobbies, hallways, and restrooms.
RSF determines the tenant's financial liability for both base rent and operating expenses. Common area allocation is calculated using a "load factor" or "core factor." For example, if a tenant occupies 10,000 usable square feet in a building with a 15% load factor, their RSF is 11,500. Rent and CAM charges are calculated on this inflated figure. BOMA (Building Owners and Managers Association) measurement standards govern how these spaces are measured, and understanding the load factor is essential for comparing different lease proposals.
