SB 684 and SB 1123 small-lot subdivisions
California now lets many lots be divided into as many as ten small, separately owned homes, approved by staff rather than argued over at a hearing. The law is generous; the land it applies to is less forgiving. We test the site before anyone commits.
What the laws allow
Together called the Starter Home Revitalization Act.
SB 684 (2023)
Lots up to five acres in multifamily and commercial zones can become as many as ten parcels, with no more than ten homes.
SB 1123 (2024)
Since July 1, 2025, the same approach on vacant single-family-zoned lots up to 1.5 acres.
1,750 sf average
Homes must average no more than 1,750 net habitable square feet.
60 days
Approval or denial of a complete application within 60 days, ministerially, with no public hearing or CEQA review.
Where the design work is
The limits that decide these projects are rarely the ones in the headline. Setbacks between homes, fire access, driveway width, utility connections, trash, and the 1,750 sf average all compete for the same ground.
We run those numbers first, then lay out lots and homes that can each be sold on their own, whether as fee-simple lots, a condominium or a tenancy in common.
- Step 1
- Zoning and feasibility study with a lot and unit count you can underwrite
- Step 2
- ROI analysis: costs, sale values and timing
- Step 3
- Tentative and final map with your civil engineer
- Step 4
- Home design, construction documents and permits
Questions owners ask
Does my lot qualify?
It depends on the zone, size, existing housing on the site and a few exclusions such as protected tenancies and hazard zones. Send us the address and we will tell you.
Can I sell the homes separately?
Yes. That is the point of the laws: each home sits on its own lot, or is held as a condominium or tenancy in common.
