Rentable square feet

**Rentable square feet**

Rentable square feet (RSF) refers to the total amount of space in a commercial property that a tenant can lease and be billed for. This measurement typically includes the tenant’s usable square footage plus a proportional share of common areas such as lobbies, hallways, restrooms, and shared facilities. Understanding rentable square feet is essential for tenants and landlords when negotiating leases, as it affects the overall cost and space allocation in office buildings, retail centers, and industrial properties.
