Note! - be aware of local restrictions, codes and their minimum values. They may diverge considerably from the numbers above.

Occupancy Rate

Occupancy Rate is maximum numbers of persons per area unit. 

If the minimum area per person is 100 sq ft - the occupation rate is 1/100 = 0.01 person per sq.ft - or 10 persons per 1000 sq.ft.
