My understanding regarding the requirement for a garbage disposal what
just that; to dispose of garbage. It was added to the building code in
many municipalities to avoid garbage going into outdoor refuse. Mainly
for improved sanitary conditions and to avoid attracting rodents and the
inherent problems that involves.

Art, curious here but I'm not aware of anyplace where they are 'required'?
They are optional as far as i know but a cheap addition so many places have
them. Are they actually required where you are?
