SB 10 is voluntary; but for the cities that do choose to use it (or selectively use it), now neighbors can’t sue to stop anything 10 units or less from going up based on environmental concerns. It’s big for that reason. SB 9 is paradigm shifting: every lot in California that’s single family zoned can a) be split into two lots AND/OR b) each resulting lot can now have up to 2 units AND c) if the lot is compliant with all other criteria, each lot is still able to have an ADU built in addition to the extra unit, per statewide ADU law passed two years ago So you can potentially turn a single lot into 6 units. Or 3 without splitting the lot. All of this is by-right, too. Design approval and local councils can’t stop it, and I believe they must be approved within 90 days, too.

This isn't quite right, unfortunately: you can only have 4 units per parcel, not 6. That's because SB9 includes ADUs in the definition of "unit," so it cannot be used to create a duplex on a lot that already has ADUs. Thus, SB9 increases the limit from 3 units to 4 units, not 6.

  AB68 applies to multi-family lots as well, and you're allowed up to 2 of them, detached from the main multi-family building: https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201920200AB68 https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml... (section 4). Do the lot split first, then the duplex construction, then construct 2 ADUs. 8 units where a SFH was before.

  You’re right, I must have read an earlier version of the bill https://leginfo.legislature.ca.gov/faces/billTextClient.xhtml?bill_id=202120220SB9 https://leginfo.legislature.ca.gov/faces/billTextClient.xhtm... “Notwithstanding Section 65852.2 or 65852.22, a local agency shall not be required to permit an accessory dwelling unit or a junior accessory dwelling unit on parcels that use both the authority contained within this section and the authority contained in Section 66411.7” However, it does not appear that the law prevents an ADU from being built without any additional rezoning, just that local cities may choose to approve/disallow it as they see fit
