SB-9 allows you to split a lot as small as 2,400 square feet

[Felicia Nitu]

In Culver City, SB-9 allows homeowners to split lots as small as 2,400 square feet, making it possible to create new housing opportunities in single-family neighborhoods. However, not every lot qualifies. The law prevents excessive subdivision by restricting who can split and how often, ensuring that newly created parcels remain practical for development.

How SB-9 Properties Work

// Minimum Lot Size & Balance
· Each new lot must be at least 1,200 square feet.
· The 2 new lots must be roughly equal in size, with neither smaller than 40% of the original lot.

// Ownership & Subdivision Limits
· A lot cannot be split again under SB-9 if it was already created through a previous urban lot split.
· The owner or anyone connected to them cannot have used an SB-9 lot split on an adjacent property.

// Development Potential
· A split lot can have up to 4 units (2 per parcel) or a duplex, plus ADUs/JADUs.


What Does This Mean for Real Estate Agents?
SB-9 creates more listings, more transactions, and more commission potential, all without needing a large lot. By educating clients on lot splits and development options, agents can position themselves as experts in a growing segment of the market.
