Frequently Asked Questions

SB9 is a California state law that allows homeowners to split their single-family lot into two parcels, making it easier to develop or sell part of their property.

Most single-family homeowners with extra land may qualify, but there are some restrictions, such as minimum lot size and environmental regulations.

The process typically takes 9-12 months, depending on the city and complexity of the split.

The total cost ranges between $75,000 and $95,000, but most costs are covered upfront, and you only pay if your lot split is successfully approved.

No full reassessment occurs, but the new lot will receive its own tax bill, with a small annual parcel tax of about $1,000 to $2,000.

Currently, you must sign an affidavit stating you intend to reside there for three years, but enforcement is unclear, and this requirement may change soon.

Yes! You can build up to two full-size homes on each lot, not just ADUs.

Historic districts are ineligible, but coastal properties may qualify with additional permitting.

If your HOA’s CC&Rs prohibit lot splits, they can override state law. However, a proposed new law (SB 677) may eliminate HOA restrictions soon.
