Here’s How New California Law Lets Homeowners Build 2 Duplexes in 2022
California enacted SB 9 to increase housing and combat a statewide housing shortage. California homeowners can tear down their existing single-family homes, split their lot into two and develop two duplexes.
Other options exist like keeping the original house, splitting the lot into two, and building up to three more housing units.
But, before you start calling a developer or a general contractor you need to know the new law’s requirements.
How to Qualify for SB 9 Lot Splitting and Development of More Housing
SB 9 Limitations
Location – The new law limits single-family parcels (lots) from developing extra housing located in these three areas:
Fire hazard zones;
Historic districts; and
Rural areas.
Lot Size Minimum – Residential lots split into two must contain at least 1,200 square feet in each lot. Yet, a local agency can allow a lower minimum.
Residential Use – Only residential housing allowed with no commercial offices or spaces.
Short-Term Rentals – None of the housing units are short-term rentals. They must rent for longer than 30 days.
SB 9 Allows
Urban areas – and urban clusters (including suburbs) in residential zones (no commercial or industrial zoning) qualify.
Prohibits Local Interference – County, city, and local jurisdictions are prohibited from interfering with any proposed lot split and development when their local ordinances or rules prevent such developments. However, the homeowner must file an affidavit stating the intention to live in one of the units as the permanent residence at least 3 years from the date of lot split approval.
Faster Development Approval – County, city and local jurisdictions can’t require hearings or discretionary review before approving the development.
Only Exceptions – The only exceptions for the county, city and local jurisdictions disapproval are:
The project creates a specific adverse impact on;
Public health and safety;
The physical environment; and
No adequate mitigation options exist.
How SB 9 Affects Local Zoning
Besides, what we explained above, questions rose about specific local zoning requirements since SB 9 passed.
Parking – Many jurisdictions require a minimum number of off-street parking for housing developments to reduce street parking congestion. Thus, local agencies can require one off-street parking space per unit. Unless the units are close to public transit or a care-sharing vehicle location.
Setbacks – Most jurisdictions require homes to sit a minimum of four feet from the rear and side property boundaries known as a “setback”. Yet, new limits cannot be imposed on existing structures or new ones in the same location with similar dimensions as the original.
Non-Conforming – Existing structures built with a non-conforming zoning condition cannot be corrected by local agencies under SB 9.
No Right-of-Way – Local agencies are prohibited from asserting right-of-way usage or requiring offsite improvements to the new construction.
Only Objective Zoning Standards – SB 9 only allows local agencies to impose “objective” zoning standards on the subdivision and new housing construction of two units (duplex). These standards cannot preclude constructing two units of at least 800 square feet.
Environmental Quality Laws Limited – SB 9 does not allow the California Environmental Quality Act (CEQA) to apply. However, the California Coastal Act does apply for coastal area construction.
How to Split Your Lot to Develop Up to Four Housing Units
California homeowners now have several options to split their lot to develop up to 4 housing units. The San Diego Union-Tribune published a chart showing all options:

How much does it cost to build a home from shipping containers?
According to Upnest, in October 2021 building an average home from shipping containers costs “around $10,000 to $35,000”. The price rises depending on how many amenities you intend to add.

20 x 8 x 8 feet giving you a surface of 160 square feet; and
40 x 8 x 8 providing a surface of 320 sq. ft.
Costs: Used containers cost between $1,500 to $2,800. While a 40-foot costs from $3,500 to $4.500.
Labor costs: Expect at least $10,000 for labor plus planning, permits, architect design, and structural engineering fees.
Longevity: Since steel containers are built to last 25 years in all weather conditions they last longer with the right care. If you buy used containers make sure they come with no rust.
Construction and Installation: You will need to lay a concrete foundation, install insulation, and add from these features:
Electricity;
HVAC system;
Flooring;
Interior doors and walls;
Plumbing (bathtubs, shower, sinks);
Shelving and closets; and

How Many Lots Qualify in California?
Last September, the UC Berkeley Terner Center published a report showing thousands of lots in the 10 most populous California counties. View the report to see how many lots are ‘market feasible” to split and develop. The report claims 410,000 lots in California are “market feasible”.
28,500 Lots are Market Feasible to Split and Develop in San Diego County
WeLease Property Management Company recently published a blog post titled: “How to Develop 28,500 Lots in San Diego County in 2022”. It explains the new law and what lots qualify and the requirements in greater detail.

If You Don’t Want to Develop Your Lot, Work with a Developer
Splitting your lot and developing extra housing takes time and money. The alternative is to contract with a developer to do all the work. Yet, you are still required to live in one of the units as your permanent residence for at least three years.
Loophole: One unanswered question that homeowners have about SB 9 is whether you can contract with a developer? Live in one unit, and joint venture with a developer to build the other units and share the profits from the rents and eventual sales. So far, no attorney has addressed this loophole. Contact an experienced California real estate lawyer to pursue this potential loophole.
Read how the Best, Best & Krieger law firm with “200 attorneys in 10 offices across California” explains the new SB 9 law.
Also, the Gibson & Dunn law firm with over 1,500 lawyers in 20 worldwide offices including 5 in California summarized the SB 9 law.
Plus, the law firm Holland & Knight with three offices in California summarized SB 9.
Yet, neither of these three law firms addressed whether California homeowners can joint venture with developers to split and develop.
Neither of these 3 California law firms answered the question: “Can I contract with a developer to split and develop my lot and share the rents and profits as a joint venture?”

Work with a Developer
If homeowners do not want to spend the time and money converting tiny homes and 40-foot containers into duplexes, they might try to work with a developer. Currently, the new law remains unclear whether qualifying homeowners can contract with developers to develop and share the rents and sales profits as a joint venture.
Seek Legal Counsel
We advise viewers to consult with an experienced California real estate attorney to explore if this possible joint venture with a developer can bear fruit under the new law.
