How many square feet per person in a office space?

For law firms with large executive offices, storage and conference rooms: 400 rentable square feet per person.

For a traditional layout of normal sized private offices: 300 SF per person

For a 50/50 mix of private office and open cubicle area: 250 SF per person

For 100% open cube area: 200 SF per person

How dense you pack your office space also is limited by the availability of parking in areas without mass transit and the capacity of the HVAC systems (especially in warmer climates)
