Historical Context
The concept of Rentable Square Footage (RSF) emerged from the need to standardize lease terms and ensure transparency in commercial real estate transactions. The standardization began in the mid-20th century, as modern office buildings with shared common spaces became more prevalent.
Definition
Rentable Square Footage (RSF) is a measurement used in commercial real estate to determine the total area for which a tenant pays rent. It includes the tenant’s Usable Square Footage (USF) plus a proportionate share of the building’s common areas, such as lobbies, restrooms, and hallways.
Types/Categories of RSF
- Office Space RSF: Applies to business offices, including shared amenities.
- Retail Space RSF: Applies to shopping centers and retail complexes.
- Industrial Space RSF: Applies to warehouses and manufacturing facilities.
Key Events
- 1950s: Formalization of rentable area calculations in commercial leases.
- 1996: BOMA (Building Owners and Managers Association) International published the first standard method of measuring floor area in office buildings.
Detailed Explanations
Formula for RSF Calculation:
Where:
- USF (Usable Square Footage): The actual space a tenant occupies.
- Common Area Allocation: A prorated share of common areas.
Example Calculation:
If a tenant’s USF is 1,000 square feet and the common area allocation is 200 square feet, then:

Importance and Applicability
RSF is crucial for:
- Determining Lease Rates: Helps in setting accurate rent prices.
- Ensuring Fairness: Tenants pay a fair share of common area costs.
- Benchmarking: Standardizes lease terms across different properties.
Examples
Office Lease:
A company leases an office space with 5,000 sq. ft. of USF and a 15% allocation of common areas. Thus, RSF is calculated as:
Considerations
- Building Efficiency: Higher RSF relative to USF indicates more common space.
- Lease Negotiations: Understanding RSF helps tenants negotiate better terms.
Related Terms with Definitions
- Usable Square Footage (USF): The actual area a tenant occupies and uses.
- Common Area Factor: The percentage of common areas allocated to each tenant.
- Gross Leasable Area (GLA): The total floor area available for leasing.
Comparisons
- RSF vs. USF: RSF includes common areas, whereas USF does not.
- RSF vs. GLA: GLA usually pertains to retail, indicating the total leasable area, which includes RSF.
Interesting Facts
- BOMA standards are often referred to as the industry bible for RSF calculations.
- RSF can vary greatly depending on the building’s design and common areas.
Inspirational Stories
Several major companies have saved significantly on lease costs by understanding and negotiating their RSF effectively, using it to relocate to more efficient buildings.

Expressions, Jargon, and Slang

Summary
Rentable Square Footage (RSF) is a fundamental metric in commercial real estate that includes usable tenant space and a proportionate share of common areas. Understanding RSF is essential for tenants and landlords to ensure fair lease rates and efficient space utilization.
