California Address Housing Shortage

ByRoof and Realm

California continues to address its housing shortage by implementing new laws to facilitate the construction of Accessory Dwelling Units (ADUs). Effective January 1, 2025, several significant changes will take effect, including Senate Bill 1211 (SB 1211), Assembly Bill 2533 (AB 2533), and Assembly Bill 434 (AB 434).

Key Provisions of the 2025 ADU Laws:

1. SB 1211 – Expansion of Detached ADUs on Multifamily Properties:

  •  Increased Allowance: SB 1211 permits property owners to construct up to eight detached ADUs on multifamily lots, provided the number of new ADUs does not exceed the number of existing units on the property. 
  •  Elimination of Replacement Parking Requirements: Local governments are prohibited from requiring the replacement of surface parking spaces when existing parking areas are repurposed for ADU construction.

2. AB 2533 – Standardization of Local ADU Ordinances:

  •  Uniformity Across Jurisdictions: AB 2533 mandates that all local ADU ordinances conform to state standards. Any local ordinance that does not align with the new state ADU laws will be rendered null and void as of January 1, 2025.

3. AB 434 – Pre-Approved ADU Plans:

  • Streamlined Approval Process: AB 434 requires all California cities and municipalities to have a pre-approved ADU plan scheme in place by January 1, 2025. This initiative aims to expedite the permitting process by allowing property owners to utilize pre-approved designs, reducing both time and costs associated with ADU construction. 

Implications for Property Owners:

  • Enhanced Development Opportunities: The expansion of detached ADU allowances on multifamily properties provides property owners with greater flexibility to increase rental income and property value.
  • Simplified Permitting Process: The standardization of local ordinances and availability of pre-approved ADU plans streamline the approval process, making it more feasible for property owners to undertake ADU projects.
  • Considerations:
  • Local Zoning and Design Standards: While state laws provide a framework, local municipalities may have specific zoning and design standards that must be adhered to. Property owners should consult with local planning departments to ensure compliance.
  • Impact on Housing Affordability: By facilitating the construction of additional housing units, these laws contribute to addressing California’s housing shortage, potentially leading to more affordable housing options in the state.

The implementation of SB 1211, AB 2533, and AB 434 represents a significant step toward increasing housing availability in California by making it easier for property owners to develop ADUs. These laws aim to streamline the development process, encourage the creation of additional housing units, and standardize ADU regulations across the state.
