How Much Space for That?
Tenants' Rules of Thumb
The general rule of thumb is to allow 175 to 250 usable square feet per person depending upon the type and style of the business. This figure can vary based upon special needs such as extra-large conference rooms or storage requirements, but will include normal amenities within a general use office. For an accurate determination of space requirements, an office space planner should be consulted.
