Condo fees questioned between units of different size/construction

We live in a Kentucky condo association.  There are 90 condo units that are 2,400 square feet and made of brick, and another 100 condo units at 1,800 square feet that are wood-framed with siding, etc.

In determining condo association fees, should the construction and cost of repair of the condo unit be taken into consideration in addition to square footage? It seems the smaller units require more frequent repair, yet condo association fees for the larger units are much higher.
