Bill Number: AB 670
Introduced: February 14, 2025
Status: Chaptered by Secretary of State - Chapter 701, Statutes of 2025
Author: Quirk-Silva
Subject: Planning and Zoning, Converted Affordable Housing Units, Housing Element

Purpose and Intent

AB 670 aims to enhance the reporting requirements for local planning agencies regarding housing elements in their general plans. The bill specifically focuses on the inclusion of converted affordable housing units in annual reports, thereby promoting transparency and accountability in housing development and ensuring that local governments are meeting their housing needs, particularly for low-income populations.

Key Provisions

  • Annual Reporting Requirements:
    Beginning with the report due on April 1, 2027, local planning agencies will be required to include additional information in their annual reports. This includes:

    • The number of new housing units created.
    • The number of housing units demolished.
    • A report on replacement housing units.

  • Inclusion of Converted Units:
    The bill allows planning agencies to include in their reports the number of units in existing multifamily buildings that have been converted to affordable housing. These conversions must meet specific criteria:

    • Units must be subject to long-term affordability covenants and restrictions.
    • Units must be available to low, very low, extremely low, or acutely low-income families at affordable rents or housing costs for a minimum of 55 years.

  • Amendments to Government Code:
    AB 670 amends Section 65400 of the Government Code, which governs the reporting requirements for planning agencies, to incorporate these new provisions.

Who Would Be Affected

  • Local Governments:
    Cities and counties will need to adjust their reporting practices to comply with the new requirements, ensuring they accurately report on housing development and conversions.

  • Low-Income Families:
    The bill aims to benefit low-income families by increasing the availability of affordable housing units and ensuring that these units remain affordable for an extended period.

  • Planning Agencies:
    Agencies will have to track and report additional data, which may require adjustments in their data collection and reporting processes.

Procedural and Timeline Aspects

  • Implementation Date:
    The new reporting requirements will take effect starting with the report due on April 1, 2027.

  • Legislative Process:
    AB 670 was approved by the Governor on October 13, 2025, and has been chaptered into law, indicating its finalization and readiness for implementation.

Conclusion

AB 670 represents a significant step towards improving the accountability of local governments in addressing housing needs, particularly for vulnerable populations. By mandating the inclusion of converted affordable housing units in annual reports, the bill seeks to foster a more comprehensive understanding of housing availability and accessibility in California.
