Today, builders are careful to not misrepresent the square footage in their agreements however; buyers must be careful and should carefully read the provisions in the agreement of purchase and sale with respect to how square footage is calculated. A typical builder agreement states that square footage is calculated from the exterior walls of the dwelling from corner to corner meaning that the square footage is actually less than the actual “liveable” or “usable” space. Moreover, if the property is a condominium unit and contains a balcony, sometimes a builder will also include the balcony as part of the total “liveable” “usable” square footage even though the balcony is an exclusive use common element and not actually owned.
