The Common Area Factor (CAF), also known as the Load Factor or Add-On Factor, is a ratio used in commercial real estate to apportion shared space among tenants. It reflects the proportion of common areas, such as lobbies, hallways, restrooms, and shared amenities, relative to the building’s total usable space. This article provides a comprehensive understanding of the Common Area Factor, its historical context, categories, key events, calculations, importance, applicability, and much more.
Historical Context
The concept of the Common Area Factor has evolved with the development of commercial real estate. Initially, commercial leases primarily focused on usable square footage. As multi-tenant buildings became more prevalent, the need to fairly distribute the cost of common areas led to the development and adoption of the CAF. This metric ensures that all tenants contribute proportionally to the maintenance and operation of shared spaces.
Types/Categories
- Gross Area Factor: Includes all space within a building, including common areas and private usable spaces.
- Usable Area Factor: Focuses only on the tenant’s private space.
- Rentable Area Factor: Combines usable space and a portion of common areas, typically what the Common Area Factor helps to calculate.
Key Events
- 1980s: The Building Owners and Managers Association (BOMA) standardizes methods for measuring rentable areas.
- 2000s: Enhanced transparency in commercial leasing agreements as tenants demand clearer breakdowns of space allocation.
Detailed Explanations
Calculation of Common Area Factor
The CAF is calculated as follows:
Once determined, this factor helps calculate the Rentable Square Footage (RSF):
Example Calculation
If a building has 10,000 square feet of usable space and 2,000 square feet of common areas:
Importance and Applicability
Understanding the CAF is crucial for:
- Tenants: Accurately assessing lease costs and comparing different properties.
- Landlords: Setting fair rental rates and distributing common area maintenance costs.
- Real Estate Agents: Advising clients on the true cost of leased spaces.
Considerations
When evaluating a lease:
- Verify the calculation: Ensure the CAF is calculated according to recognized standards.
- Compare different buildings: Different buildings may have varying CAFs, impacting overall rental costs.
- Negotiate: Tenants can negotiate the CAF as part of the lease terms.
Related Terms
- Usable Square Footage (USF): The space that a tenant can actually occupy and use.
- Rentable Square Footage (RSF): The USF plus a share of the building’s common areas.
- Load Factor: Another term for the Common Area Factor, representing the ratio of total space to usable space.
Comparisons
| Term | Definition | Typical Use |
|---|---|---|
| Usable Square Footage (USF) | The space a tenant can use exclusively. | Tenant-space |
| Rentable Square Footage (RSF) | USF plus a portion of the common areas. | Lease agreements |
| Common Area Factor (CAF) | Ratio of common areas to the total usable space. | Cost allocation |
Interesting Facts
- BOMA’s standards have been adopted globally, providing a consistent framework for measuring commercial space.
- High-rise office buildings typically have higher CAFs due to extensive common amenities.
Famous Quotes
- “Real estate cannot be lost or stolen, nor can it be carried away. Managed with reasonable care, it is about the safest investment in the world.” — Franklin D. Roosevelt
Proverbs and Clichés
- “Location, location, location” – highlighting the importance of a property’s position.
- “Measure twice, cut once” – emphasizing the need for accuracy in real estate measurements.
Jargon and Slang
- “Gross-up” – Adjusting usable square footage to include a share of common areas.
- “Net rent” – Rent calculated without common area maintenance fees.
FAQs
Q: How does the Common Area Factor affect my rent? A: The CAF increases the usable square footage to include a portion of common areas, thus affecting the total rentable space and rent.
Q: Can the Common Area Factor change? A: Yes, changes in building layout or shared services can alter the CAF.

Final Summary
The Common Area Factor is an essential metric in commercial real estate that ensures fair distribution of the cost of shared spaces among tenants. By understanding and accurately calculating the CAF, both tenants and landlords can make informed decisions that reflect the true cost and value of leased spaces. This metric’s development and standardization have brought greater transparency and fairness to the commercial leasing process, benefiting all stakeholders involved.
