Senate Bill 9, also called the California Housing Opportunity and More Efficiency (“HOME”) Act, was signed into law on September 16, 2021. The act enables

a) creation of a duplex on a single-family lot and
b) subdivision of a single-family zoned lot to construct either a single-family or duplex home on each lot resulting from the subdivision. In addition, state law and the applicable City’s zoning ordinance may allow accessory dwelling units (ADUs) to be constructed on these properties.

Thus, You can use SB9 to split your lot, add a 2nd home to a lot, or both (split lot and have 2 homes on each lot for a total of 4 homes). SB-9 simplifies and speeds up the permission process, making it easier and more accessible for landowners to add extra housing to their property.

At PlumReef, we specialise in carrying out lot splits and can assist you in determining the application of SB-9 for your property and determine the feasibility of construction of your dream house on the lots. These lots can also be sold separately.
