California SB9

On January 1, 2022, California Senate Bill 9 (SB9) took effect. SB9 is a new state law that allows homeowners to build up to two additional units on their single-family lots, potentially doubling the number of homes on a lot.

The law allows homeowners to convert their single-family homes into duplexes, triplexes, or fourplexes, depending on local zoning laws. Homeowners can also build new structures up to two stories high, with a maximum height of 16 feet, without needing to go through the usual process of getting permits for parking, setbacks, and other requirements.

In addition, the law prohibits local governments from imposing minimum lot size requirements and reduces the fees and other barriers to building accessory dwelling units (ADUs), also known as granny flats, on single-family lots.

Proponents of SB9 say that it will help alleviate California's housing crisis by increasing the number of affordable housing units and allowing more people to live in established neighborhoods. Opponents argue that it will lead to overcrowding and exacerbate parking and traffic issues.

It's important to note that SB9 is not a blanket rule and does not automatically apply to every single-family home in California. Local governments still have the power to impose their own zoning laws and regulations. Homeowners interested in taking advantage of SB9 should check with their local planning department to see if their lot is eligible and what specific rules and regulations apply.
