No - biodiesel is used just like petro-diesel. No heaters, no alterations to the vehicle at all.
The only climate issue with running biodiesel is that it will gel at a higher temp than will petrodiesel - and no, you will never encounter temperatures cold enough for that in SoCal - unless you are in Big Bear and they have record low temperatures one winter night.
