You can use either square footage or income to determine if the property is primarily business or dwelling. If it's priimarily business, then it's not HMDA reportable.
From GIR page D-5:
Mixed-use property. A dwellingsecured
loan to purchase property
used primarily for residential purposes
(for example, an apartment building
containing a convenience store) is a
home purchase loan. An institution
may use any reasonable standard to
determine the primary use of the property,
such as by square footage or by
the income generated. An institution
may select the standard to apply on a
case-by-case basis.
