California housing bills 8, 9 and 10: historical coverage
This September 2021 news item is preserved as historical coverage. Its old summaries are not current parcel-specific entitlement advice.
Planning information only. Confirm local requirements and review financing, tax treatment, scope, and costs with the appropriate professionals.
This page originally linked to the governor's September 2021 announcement about SB 8, SB 9, and SB 10. These are distinct housing measures, not a universal promise that an owner can add a particular number of units or split any lot.
Read the announcement as history
The September 16, 2021 governor's announcement records the legislation at that time. We have removed the old compressed eligibility summary and diagram from this page because they should not be used to determine current rights.
Check the proposal, not just the bill number
Ask the jurisdiction which rules apply to your lot and whether you are proposing an ADU, a lot split, or another form of housing. Those pathways have different requirements. Get a documented answer before basing a purchase or construction budget on an assumed unit count.
For ADUs, start with California HCD's current program page and the handbook it links. For the financial comparison, read the buyer, homeowner, and investor guide.
