A BOMA Area Calculator helps estimate rentable and allocable commercial building area using BOMA (Building Owners and Managers Association) standards.
This calculator is commonly used in commercial real estate, office leasing, property management, and building planning to calculate rentable area, common area allocation, and total BOMA area.
By entering the usable floor area, building common area, floor allocation factor, and number of floors, you can quickly estimate commercial building area measurements.
Allocated Common Area Formula
The allocated common area is calculated using the building common area and allocation factor.
Allocated Common Area=Building Common Area×Floor Allocation Factor
Rentable Area Formula
The rentable area is calculated by adding usable floor area and allocated common area.
Rentable Area=Usable Floor Area+Allocated Common Area
Total BOMA Area Formula
If multiple floors are included:
Total BOMA Area=Rentable Area×Number of Floors
Load Factor Formula
The load factor represents the ratio between rentable area and usable area.
Load Factor=Usable Floor AreaRentable Area
How the BOMA Area Calculator Works
The calculator first determines the allocated common area using the floor allocation factor. It then adds the common area allocation to the usable floor area to estimate rentable area.
Finally, it calculates:
- total BOMA area
- load factor
- allocable building area
This calculation is useful for:
- office leasing
- commercial real estate
- property management
- building planning
- tenant area calculations
Example Calculation
Suppose:
- Usable Floor Area = 10,000 sq ft
- Building Common Area = 2,000 sq ft
- Floor Allocation Factor = 0.15
- Number of Floors = 5
Step 1: Calculate Allocated Common Area
Allocated Common Area=2000×0.15
Allocated Common Area Result
Allocated Common Area=300 sq ft
Step 2: Calculate Rentable Area
Rentable Area=10000+300
Rentable Area Result
Rentable Area=10300 sq ft
Step 3: Calculate Total BOMA Area
Total BOMA Area=10300×5
Total BOMA Area Result
Total BOMA Area=51500 sq ft
Step 4: Calculate Load Factor
Load Factor=1000010300
Load Factor Result
Load Factor=1.03
Applications of BOMA Area Calculation
This calculator is useful for:
- Commercial office leasing
- Property management
- Real estate development
- Building planning
- Tenant area calculations
- Office space estimation
Benefits of Using a BOMA Area Calculator
- Fast and accurate commercial area estimation
- Helps calculate rentable office space
- Useful for lease agreements
- Simplifies building management calculations
- Reduces manual calculation errors
FAQs
What is BOMA?
BOMA stands for Building Owners and Managers Association.
What is usable floor area?
Usable floor area is the actual occupiable tenant space inside a building.
What is rentable area?
Rentable area includes usable area plus a share of common building spaces.
What is a load factor?
The load factor represents the ratio of rentable area to usable area.
Why are common areas included?
Shared areas such as hallways and lobbies are distributed among tenants using allocation factors.
