SB9 can be powerful because a qualifying property may be able to split into two legal lots, and each resulting lot may support residential units. In the right case, the law can create a path toward up to four residential units.
What homeowners need to know first.
A qualifying SB9 strategy may create two legal parcels and, depending on the property and local standards, a path toward two full-sized homes per lot or up to four residential units.
The practical details matter more than the headline.
Two legal lots
The first major opportunity is the urban lot split itself, which can create two separately defined parcels.
More housing options
Each resulting lot may support residential development if the physical site and objective standards allow it.
Property-specific limits
The exact outcome depends on zoning, size, access, utilities, title, fire, drainage, and local implementation.
Riechers reviews the real property, not just the idea.
This is where SB9 can be misunderstood. The headline sounds simple, but the outcome depends on how the site actually works after the split.
In a strong case, the owner may create a strategy for two legal lots and additional housing opportunities. In a weak case, the law may not overcome the physical or financial constraints of the property.
A feasibility review helps separate what the law may allow from what the property can practically support.

State rules and local review both matter.
What a Typical Lot Can Become Under SB9 FAQs
Can SB9 create up to four residential units?
In the right situation, SB9 can create a path toward up to four residential units, but the final answer depends on the property, local standards, and full legal requirements.
Does every lot become four units?
No. Many lots cannot support the maximum theoretical outcome because of size, access, utilities, setbacks, drainage, fire access, or local standards.
Can SB9 allow two full-sized homes per lot?
Potentially, yes, depending on the split, the resulting lots, and the applicable standards. The project must be reviewed property by property.
