1. What is Commercial Building Square Footage?

Commercial building square footage refers to the total floor area of a commercial property, measured in square feet. It includes all usable space across multiple floors and is a critical metric for property valuation, leasing, and space planning.

2. How Does the Calculator Work?

The calculator uses a simple summation formula:

Where:

• \( Floor\ Area_i \) — Area of each individual floor in square feet
• \( n \) — Number of floors in the commercial building

Explanation: The calculator simply adds together the square footage of each floor to determine the total area of the commercial building.

3. Importance of Square Footage Calculation

Details: Accurate square footage calculation is essential for property valuation, rental pricing, tax assessment, building code compliance, and space utilization planning in commercial real estate.

4. Using the Calculator

Tips: Enter the square footage for each floor of your commercial building. At minimum, enter the area for Floor 1. You can add up to 5 floors. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is included in commercial square footage?
A: Typically includes all interior space measured from the inside faces of exterior walls, excluding mechanical rooms, elevators, and stairwells.

Q2: How is square footage different from rentable area?
A: Rentable area often includes a proportionate share of common areas, while square footage typically refers to the actual usable space.

Q3: Should I measure to the exterior or interior walls?
A: Commercial square footage is typically measured to the interior face of exterior walls (the "inside paint").

Q4: Are there standard measurement standards?
A: Yes, the BOMA (Building Owners and Managers Association) standards are widely accepted for commercial measurements.

Q5: How do I account for irregularly shaped floors?
A: Break the floor into regular shapes (rectangles), calculate each area separately, then sum them together.
