The California Senate Bill 9, also known as the Housing Opportunity and Mobility Expansion (HOME) Act, allows for the construction of up to four residential units on a single-family lot, where local zoning ordinances allow for it. Here is a brief overview of the process:
- Under SB-9, an owner of a parcel zoned for single-family use can apply for a permit to build up to two accessory dwelling units (ADUs) or to divide the parcel into two equal sized lots, each of which is zoned for residential use.
- On each new parcel, the owner can build a primary residence and an ADU, for a total of 4 units on what was once a single-family lot.
- The bill sets some restrictions on the size and design of the units and requires that there be adequate off-street parking available.
- The local government has certain requirements that must be met before the permit can be issued, including notifying neighbors of the intention to build on the property and meeting certain design standards.
By allowing greater flexibility in land use, SB-9 aims to increase housing supply in California and provide more affordable options for residents.
