conversion to condominium

[Leah M.]

If a triple family multifamily is converted to condominium, how is the square footage of each condominium determined? How does it relate to the living area square footage recorded by the city for the multifamily? For example, if the city has a multifamily measuring 3000 square feet of living space, will the total square footage of the three condominiums also equal 3000, or is a different means of measurement used.  Thanks!
