Minimum square footage needed for 2BR ADU?

[Bruce P.]

Hi all, with the passage of the new California SB-13 and associated laws, what is the minimum square footage needed to accommodate a 2 bedroom / 1 bath ADU and a 2 bedroom / 2 bath ADU? My friend is thinking about not going with their original 1BR / 1 Bath ADU plan since 2 BR in Southern California could potentially fetch $2K per month and up is their thought (they are in the Westlake / Moorpark area of Ventura county). But I thought to ask the larger BP community for their collective wisdom.
