We at BPF use $333 / month as an average lease cost per employee for our high level financing projections for service based companies. We use an average of 200 sq ft per person at a Toronto average of $20 per square foot per year.

We have seen the richer firms allocating more than 400 square foot per person and smaller firms doing less than 200 sq ft per year.

For service based companies, it is always wise to do an average sq ft of  200 or more because anything lesser than that would mean diminishing results from your employee because of the ‘cramped’ atmosphere. People are whats expensive, not space.
