What Are SB-9 Projects?

In 2021, California passed Senate Bill 9 (SB-9) to help ease the state’s housing shortage. This law makes it easier for homeowners to create more housing units on their property by allowing:

Lot Splits

SB-9 lets you legally split a single-family residential lot into two separate parcels. Each new parcel can then be sold or developed independently.

Duplex Conversions

On top of lot splits, SB-9 also allows homeowners to convert an existing single-family home into a duplex (two separate units) or build new duplexes from the ground up.

Up to Four Units on One Lot

Here’s where it gets exciting: because SB-9 allows two homes per lot, a single lot split could hold up to four homes total—doubling the housing potential and property value.

Benefits of SB-9

Create a New Income Stream

The most common reason homeowners pursue SB-9 is to generate rental income. By splitting your lot or adding a duplex, you can create one—or even multiple—new units that bring in steady monthly rent, helping cover mortgage payments or build long-term passive income.

Maximize Property Value

Adding additional units to your property can significantly increase its appraised value. With SB-9, a single-family lot can potentially hold up to four homes (two on each split parcel), multiplying the equity in your property and boosting future resale value.

Build Wealth Without Buying More Land

Land in California is expensive. SB-9 allows you to unlock hidden value in the property you already own, creating more housing without having to purchase a new lot. This is one of the most cost-effective ways to grow wealth in real estate.

Flexibility for the Future

Rent out the new units now, use them for family later, or sell one of the parcels for cash. SB-9 gives you options and financial flexibility that single-family zoning never allowed.
