Part 1: What is the typical, most common way that Commercial Building
Owners Associations determine fees?  Is it most often based on lot
size, or square footage or use of common areas?
Part 2:  Are common area fees ever passed on to building owners based
on use of those common areas?  For example, if one building was 10,000
sq. feet and another building was 5,000 sq. feet and the association
were to pay for exterior painting it would be appropriate for the
10,000 sq. foot building to pay twice as much as the 5,000 sq. foot
building since it will use twice as much paint.  If however, there was
a fountain between the 5,000 sq. foot building and the street, which
the 10,000 sq. foot building could not see from it's lot, and the
fountain needed maintenance - is it ever customary or even an option
to charge the buildings based on "use" for some items rather than
square footage or lot size and the 10,000 sq. foot building paying
twice as much as the 5,000 sq. foot building for a fountain that the
10,000 sq. foot building cannot even see from its lot?
