Why AB 1033 Matters For Additional Dwelling Units in 2024

California Assembly Bill 1033 (AB 1033) introduces several advantages for those interested in purchasing or building accessory dwelling units (ADUs). Here are some reasons why AB 1033 is considered beneficial for ADU buyers in San Diego and Los Angeles


AB1033 Streamlines The Permitting Process for ADUs In San Diego and Los Angeles

AB 1033 mandates that local agencies approve or deny ADU permit applications within a 60-day period, which significantly expedites the process. This is a substantial improvement over previous procedures that could be lengthy and unpredictable. If the agency does not act within this timeframe, the application is deemed approved.

Designation of Permissible Areas

The bill allows local agencies to designate areas where ADUs can be created, based on factors such as the adequacy of water and sewer services and the impact on traffic flow and public safety. This clarity helps buyers understand where they can legally build ADUs.

AB 1033 requires the imposition of objective standards on ADUs: 

Which may include parking, height, setback, and landscape requirements. This helps to ensure that ADUs are built to a certain quality and are in harmony with the surrounding community.

Flexibility in Sales

The bill allows for the separate sale or conveyance of ADUs under certain conditions, providing more flexibility for ADU owners. This could potentially make ADUs a more attractive investment, as they can be sold independently of the primary residence.

Consistency with Local Zoning

AB 1033 ensures that ADUs do not exceed the allowable density for the lot and are consistent with the existing general plan and zoning designation. This helps maintain the character of neighborhoods while still allowing for the development of new housing units.

Protection Against Local Ordinances

The bill prohibits local ordinances, policies, or regulations from being the basis for the delay or denial of a building permit for an ADU. This protection means that ADU buyers and builders won't be hindered by potentially restrictive local laws.

No Impact on Residential Growth Limits

ADUs built in accordance with AB 1033 are not considered in the application of any local ordinance, policy, or program to limit residential growth. This ensures that the addition of ADUs does not affect the overall density calculations for a given area, which can be a concern in growth-managed communities.

In summary, AB 1033 provides a more streamlined and transparent process for the creation and purchase of ADUs, which can help alleviate housing shortages by making it easier for homeowners to add these units to their properties. The bill's provisions are designed to encourage the development of ADUs while maintaining the integrity of local neighborhoods and ensuring that new units are built to objective standards.


Assembly Bill 1033 History And Its Ties To Additional Dwelling Units In San Diego And Los Angeles

The history of California's AB 1033 and its implications mark a notable chapter in addressing the state's housing crisis. Sponsored by Assembly Member Phil Ting from San Francisco, AB 1033 was signed into law by Governor Gavin Newsom, signaling a significant shift in housing policy within California. The law, which allows for the separate sale of Accessory Dwelling Units (ADUs) from their primary residences, is aimed at increasing housing availability and providing more opportunities for homeownership. This move aligns with federal initiatives aimed at mitigating housing affordability issues, underpinning the synergy between state and federal policies to tackle the housing challenge head-on.

AB 1033 stands out for its flexibility, offering potential homeowners a new avenue to affordable housing. For example, the policy enables consideration of 75% of the estimated ADU rental income for some borrowers, facilitating their qualification for FHA-insured mortgages. This flexibility, coupled with standardized guidelines for ADU valuation, enhances transparency in ADU transactions, fostering confidence among buyers and sellers alike.

The enactment of AB 1033 is part of a broader legislative effort to address California's housing shortage. Alongside AB 1033, other housing laws like AB 434, which shortens the timeline for Housing and Community Development (HCD) review of housing elements, and AB 1485, enhancing the Attorney General's ability to intervene in housing enforcement suits, collectively aim to streamline and expedite the development of new housing units.
