Occupancy Rate & Formulas

Occupancy Rate ( $R_{occ}$ ) is the maximum number of persons per unit area.

R_{occ} = \frac{1}{A_{min}}

Where:

$R_{occ}$ = Occupancy Rate (persons per ft² or m²)
$A_{min}$ = Minimum required area per person (ft² or m²)

Example: If the minimum area per person ( $A_{min}$ ) is 100 ft², the occupancy rate is:

R_{occ} = \frac{1}{100\ \text{ft}^2} = 0.01\ \text{persons per ft}^2

This is equivalent to 10 persons per 1000 ft².

Unit Conversions & Notes

$1\ \text{m}^2 = 10.764\ \text{ft}^2$
$1\ \text{ft}^2 = 0.0929\ \text{m}^2$

Important Note: The area values provided are general guidelines. Always be aware of and adhere to local building restrictions, codes, and their minimum requirements, which may differ considerably from the values above.
