California’s SB9 Housing Law Effect on Single-Family Zoning

Sep 20, 2021

Senate Bill 9, promoted by Senate leader Toni Atkins and supported by Assembly Speaker Anthony Rendon, both Democrats, would make it easier to build smaller second units on what are now single-family properties. That could include up to four units, such as duplexes or homes with attached living units, if the lot is split into two equal parcels under the bill. (Nhat V. Meyer/Bay Area News Group)   


Gov. Gavin Newsom this week signed a pair of bills into law that effectively put an end to traditional single-family zoning restrictions in most neighborhoods statewide.


Senate Bills 9 and 10, which take effect Jan. 1, 2022, will make it easier for Californians to build more than one housing unit on many properties that for decades have been reserved exclusively for single-family homes and will give cities greater flexibility to place small apartment complexes in neighborhoods

near public transit.


Although the laws represent two new approaches toward alleviating the state’s housing crisis, experts say neither is likely to produce the number of units needed to fully resolve it.


Here are answers to some questions you may have about these new laws.


What is Senate Bill 9?


Senate Bill 9 is the most controversial of the two new laws. It allows property owners to split a single-family lot into two lots, add a second home to their lot or split their lot into two and place duplexes on each. The last option would create four housing units on a property currently limited to a single-family house.


The new law will mark a shift from current policies that allow only two large units — a stand-alone house and an accessory dwelling unit — on single-family lots, as well as an attached junior unit no larger than 500 square feet.

Under the new law, cities and counties across California will be required to approve development proposals that meet specified size and design standards.

What are the caveats?



The law is designed to create additional housing while also preserving low-income, affordable units.


A proposed project under this new law cannot result in the demolition or alteration of affordable or rent-controlled housing or market-rate housing that has been occupied by a tenant in the past three years. Properties listed as historic landmarks or those located within a historic district are off-limits for new development. Wetlands, farmland and properties at high risk of fire or flooding are also exempt.


If someone chooses to split their property in two, each new lot must be at least 1,200 square feet, according to the new law.


Any unit created as a result of the law cannot be used for short-term rentals. They must be rented for a term longer than 30 days.

Who can do this?


Homeowners or landlords can apply to upzone their properties through their local jurisdiction, but only if they plan to live on the property for a while.


Property owners must sign an affidavit stating they will occupy one of the housing units as their primary residence for at least three years after splitting their property or adding additional units.


Does this law allow for offices and new housing units on single-family properties?


No. Any new units created under SB 9 must only be used for residential purposes.


Do cities and counties have to abide by this new law?


Under SB 9, local government officials may only deny a development application if they find that the proposed project would have a “specific, adverse impact” on “public health and safety or the physical environment” and there are no feasible and satisfactory mitigation options.


Will local rules about maximum square footage, building height and parking apply?


Proposals under this new law must adhere to objective zoning and design review standards established by local cities and counties. Developments must still follow local zoning rules such as those governing height and yard size requirements.


No parking is required for additional units if the property is within a half-mile of a major public transit stop. However, a local agency can require up to one parking space per unit if there are no frequent transit stops nearby.


Will this law put a dent in California’s housing shortage?


A recent study by the Terner Center for Housing Innovation at UC Berkeley estimated that just 5.4% of the state’s current single-family lots has the potential to be developed under SB 9, making construction of up to 714,000 new housing units financially feasible. That’s only a fraction of the 3.5 million new housing units Gov. Newsom wants to see built by 2025.


What is Senate Bill 10? 


Senate Bill 10 eases the process for local governments to rezone neighborhoods near mass transit or in urban areas to increase density with apartment complexes of up to 10 units per property. The new legislation also allows cities to bypass lengthy review requirements under the California Environmental Quality Act in an attempt to help reduce costs and the time it takes for projects to be approved.

California is facing a housing shrtage estimated at 2.5 and 3.5 million homes. America is short around six million homes, which is a big reason why home prices are still high. California is one of the most housing-constrained markets for years. Bay Area listings in 2023 were below historical norms. There’s no reason to think that will change in 2024. California is known to build 250,000 homes per year, which has exceedingly fallen short of demand. Last year, there were only 70,000 single-family home permits issued throughout California. Sellers keep the upper hand.

Today, nearly 20% of housing units built in California are accessory dwelling units (“ ADUs ”). According to the California Association of Realtors Housing Affordability Index, only 17% of households can afford a single-family home, less than half of the national average. In many States across the country, ADU condo conversion projects are re-enabling a generation of home buyers to live in the communities of their choice near work and family. The State of Washington recently required all local agencies to allow conversions of a primary unit and ADU to condominiums for sale. Consequently, in Seattle and Portland 40% to 50% of ADUs constructed are sold as condominiums to new homebuyers, where they are bought for approximately half the value of a stand-alone single-family home. Such ADU condo conversion purchases are eligible for federally guaranteed mortgages, making them easy to finance for ordinary homebuyers. The California State Legislature recently adopted a new law, AB1033, AB1033 removes the previous State law prohibition against mapping and selling a single-family home and its ADU as condominiums. Even though this prohibition on condo conversion has been eliminated, it is up to Local Agencies to amend their codes to allow these entry-level home ownership opportunities. WHAT NEEDS TO BE DONE TO ALLOW SALE OF ADUS? Respecting local control, the Legislature left it up to Local Agencies to amend their municipal code(s) to allow these entry-level home ownership opportunities through the sale of ADUs. The Casita Coalition and Reuben, Junius, and Rose, LLP have developed this guidance to encourage your Local Agency to make the following changes to your code(s), procedures and policies to re-enable Californians priced out of many of our communities to once again have a dream of buying a home by enabling more naturally-affordable condominiums for sale. RECOMMENDED STEPS TO IMPLEMENT SALE OF ADUS 1. Eliminate Sale Restrictions. Remove all provisions in your municipal code that prohibits the sale or other conveyance of an ADU. These restrictions are typically included in local Condominium Codes and Zoning Codes. 2. Adopt Legislation Expressly Allowing ADU Sales. To align local rules with State law, adopt changes to the municipal code that allow conversion of a home and its ADU into condominiums subject to the requirements of the Davis- Stirling Common Interest Development Act (Cal. Civ. Code Sec. 4400-6150.) Appropriate amendment text will differ depending on the existing municipal code, but AB1033 requires a list of express provisions be included in such local ordinance, attached at the end of this document. 3. Publish ADU Checklists. Provide a comprehensive checklist for any ADU building permit and for ADU condominium/subdivision projects, indicating Subdivision Map Act compliance and lender subordination information. 4. First Right of Offer to Owner Occupants. To further encourage new homeownership, consider including a condition of approval for establishing condominiums of a primary unit and ADU giving a first right of offer for a period of 45 days on publicly accessible databases, e.g., MLS, to buyers indicating an intent to live in the property (either themselves or their immediate family). To avoid issues with lenders, however, do not require owner occupancy. 5. Create “Grow Homeownership” Program . Establish a program with dedicated staff that expedites ADU condominium processing with first comments to be issued within 45 days of submission of a complete application. Consider waiving or reducing application and impact fees otherwise applied to condominiums. The Grow Homeownership Program could be paired with other funding programs your jurisdiction may have, e.g., through SB2 (2017) funds. If you have any questions or would like to discuss any of the above, please do not hesitate to reach out to Justin A. Zucker from Reuben, Junius & Rose, LLP at 415.656.6489 or jzucker@reubenlaw.com .

Prior to recordation or modification of your subdivision map and condominium plan, any lienholder with a lien on your title must provide a form of written consent either on the condominium plan, or on the lienholder’s consent form attached to the condominium plan, with text that clearly states that the lender approves recordation of the condominium plan and that you have satisfied their terms and conditions, if any. In order to secure lender consent, you may be required to follow additional lender requirements, which may include, but are not limited to, one or more of the following: (a) Paying off your current lender. You may pay off your mortgage and any liens through a refinance or a new loan. Be aware that refinancing or using a new loan may result in changes to your interest rate or tax basis. Also, be aware that any subsequent modification to your subdivision map or condominium plan must also be consented to by your lender, which consent may be denied. (b) Securing your lender’s approval of a modification to their loan collateral due to the change of your current property legal description into one or more condominium parcels. (c) Securing your lender’s consent to the details of any construction loan or ground lease. This may include a copy of the improvement contract entered in good faith with a licensed contractor, evidence that the record owner or ground lessee has the funds to complete the work, and a signed statement made by the record owner or ground lessor that the information in the consent above is true and correct.” (F) If an accessory dwelling unit is established as a condominium, the local government shall require the homeowner to notify providers of utilities, including water, sewer, gas, and electricity, of the condominium creation and separate conveyance. (G) (i) The owner of a property or a separate interest within an existing planned development that has an existing association, as defined in Section 4080 of the Civil Code, shall not record a condominium plan to create a common interest development under Section 4100 of the Civil Code without the express written authorization by the existing association. (ii) For purposes of this subparagraph, written authorization by the existing association means approval by the board at a duly noticed board meeting, as defined in Section 4090 of the Civil Code, and if needed pursuant to the existing association’s governing documents, membership approval of the existing association. (H) An accessory dwelling unit shall be sold or otherwise conveyed separate from the primary residence only under the conditions outlined in this paragraph or pursuant to Section 65852.26.

A new law allows homeowners to sell ADUs like condos, boosting homeownership. Here’s how AB 1033 works: Accessory dwelling units, also referred to as ADUs and “granny flats,” have been available in California only as rentals. But a new law, Assembly Bill 1033, is giving Californians the opportunity to buy and sell them as condominiums. ADUs come in all shapes and sizes — for example, a converted garage, a small home in the backyard, or, as often seen in San Francisco, an unused portion of the main house, said Assemblyman Phil Ting (D-San Francisco), who drafted the legislation. Under AB 1033, which was signed into law this week, property owners in participating cities will be able to construct an ADU on their land and sell it separately, following the same rules that apply to condominiums. It gives homeowners more options for building on their property, and “the hope is, it would create more homeownership,”said Ting. Under the new law, local governments need to opt in to the ADU-as-condominium approach for it to be an option in their cities.  Here’s how the new rules will work in participating cities: As with new condominiums, homeowners building ADUs must notify the local utilities, including water, sewer, gas and electric, of the creation and separate conveyance of the unit. Each property will also have to form a homeowners association to assess dues to cover the cost of caring for the property’s exterior and shared spaces, such as the driveway, a pool or a common roof. Similar to condominiums on one property, the home and the ADU will have two different property taxes, Ting said. He says he believes that many of the initial ADUs going through this process will be sold to the family members or close friends of the homeowner. “And then as people are more comfortable with this and you see more ADUs being sold, and it’s more prevalent, then I could see this being more of a traditional real estate transaction,” he said. Meredith Stowers, a loan officer at CrossCountry Mortgage in San Diego who specializes in ADUs, said AB 1033 benefits both homeowners and new buyers. “The typical homeowners we see are retirees who have long since paid off their mortgage, but are maybe living on a pittance of Social Security and meager retirement funds,” she said. Under this law, the retirees can earn supplemental income and young families can buy an affordable starter home. Stowers said the problem that retirees are facing is that, “after so many years of loan modifications in high rates, it doesn’t make financial sense for the retiree to move out of their home.” She argues it’s more expensive for them to downsize to a smaller house, and this new piece of legislation opens opportunities for retirees to leverage the equity they’ve built up in their homes while also creating affordable housing. “We’re even seeing some retirees add ADUs in their backyard that they then move into and potentially selling off their home,” she said. Selling ADUs as condominiums is having success in places such as Oregon, Texas and Seattle. When Seattle removed regulatory barriers that discouraged property owners from constructing ADUs in 2019, the city issued nearly 1,000 ADU permits, more than four times the number permitted in 2018, according to a report released in March. The report also found that in 2022, the city permitted 437 attached ADUs and 551 detached ADUs, which it referred to as backyard cottages. Just under half were on sites with multiple ADUs and one-third were part of a development that included a new single-family residence. Included in the report were sample sales for neighbor residential parcels with detached ADUs, reporting that a unit of more than 1,000 square feet sold for an average of anywhere between $500,000 to $800,000.

Deciding between a guest House and an Accessory Dwelling Unit depends on your specific needs and reasons. A Guest House offers separate accommodation on your property, suitable for visitors or potential rental income. It provides privacy but may have regulations and construction cost limitations. On the other hand, an ADU refers to a self-contained living space within your existing home or attached to it. ADUs offer versatility and can serve as a rental unit, home office, or additional living space. They often have more streamlined regulations and might be more cost-effective than building a separate Guest House. However, the choice depends on your budget, space availability, and long-term plans. option.

Navigating California’s Accessory Dwelling Unit (ADU) regulations involves completely understanding the state’s guidelines for building secondary residential units on existing properties. According to data from the Department of Housing and Community Development, the Building Departments across the state went from issuing around 9,000 ADU permits in 2018 to almost 12,400 in 2020, which is nearly a 30% increase per year. Hence, to actively support ADU construction, California lawmakers continue to pass laws that are in favor of homeowners. California gives leverage to its ADU regulations to promote affordable housing options. Homeowners must follow local zoning codes, property size and further setback requirements. Furthermore, this process typically involves obtaining necessary permits, ensuring compliance with building codes, and addressing parking and utility considerations. Connect with local authorities or professionals about ADU regulations in California to help streamline the process and ensure successful compliance. Types of ADUs Allowed in California California allows various Accessory Dwelling Units to help fix the housing shortage. However, the types may include: ● Attached ADUs (constructed within or attached to an existing primary residence) ● Detached ADUs (separate structures on the same property) ● Junior ADUs (small units within an existing home) ● Garage Conversion ADUs (conversion of existing garages Additionally, these units offer flexible housing options and can help homeowners get passive income or provide housing facilities for family members. Although ADU rules and regulations vary by city and country, it’s important to check local law and ordinances, and zoning regulations before building an ADU. Size and Design Guidelines regulation for building California’s ADU California’s Accessory Dwelling Unit regulations provide size and design guidelines that promote housing variety. California allows ADUs up to 1200 square feet for attached units, and 800 square feet for detached units. These regulations encourage adaptable designs, ensuring compatibility with existing neighborhoods and increasing housing stock. However, strategies must fulfill height requirements and local zoning. It is essential to check the current guidelines, as they have been updated occasionally. Do you need a permit for ADU in California? Absolutely! Obtaining a permit for an ADU (Accessory Dwelling Unit) in California is generally required. California state legislation and local regulations mandate permits for ADU construction or conversion. However, California relieved ADU regulations to promote affordable housing, but zoning, building codes, and permits highly depend on the city and country. Permits ensure compliance with safety, health, and land regulations. Navigating the permit process and legal requirements accurately is essential, as they might have evolved annually. What is the Permitting Process for ADUs? The permitting process required for Accessory Dwelling Units (ADU) typically involves several steps, which may include: ● Check local zoning, rules and regulations, and building codes to ensure your property is eligible for an ADU. ● Prepared detailed plans and architectural drawings for the ADU's design and layout. ● Submit your permit application to the relevant local government department, including the required fees and documents. ● The process may require some time. It depends on the specific location and type of requirement. ● You will need to submit plans to the city. ● The permitting process typically takes three to nine months in California. ● The application will be double view for compliance with zoning, building, and safety codes. This may involve inspections, corrections, or revisions. ● Once it is approved, you’ll receive the permit to start construction. ● Clear communication with local authorities and adherence to regulations are crucial throughout the process. ● Consulting with experts can help align the permitting process and ensure a successful project.
