AB 670: Planning and zoning: housing element: converted affordable housing units. - California

10/13/25 - Chaptered → AB670 · 1 edit

MINOR

This diff reflects a change in document presentation format rather than a change in legislative content. The bill text transitions from the official authenticated chaptered format (with page numbers, 'Ch. 701' headers, and formal state header) to a web-based display format that includes website navigation elements such as menus, search boxes, and version selectors. The underlying legal provisions of AB 670 remain unchanged.

TECHNICAL

The document was reformatted from the official chaptered bill layout (with page numbers, running headers like 'Ch. 701', and the 'STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGISLATION MATERIAL' header) to a web page format that includes site navigation, search tools, version history links, and other UI elements.

MINOR

This is a standard transition from enrolled to chaptered form with no substantive policy changes. The bill was assigned Chapter 701, the Governor's approval date of October 13, 2025 was recorded, and procedural passage pages were removed. All statutory text remains identical between versions.

TECHNICAL

Bill was assigned chapter number 701 and the Governor's approval date (October 13, 2025) was added to the document header.

Procedural pages showing Assembly passage (September 12, 2025), Senate passage (September 11, 2025), and Governor's receipt were removed and replaced with a standard 'STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGAL MATERIAL' header.

Page numbering changed from 'AB 670' format to 'Ch. 701' format throughout the document, and line wrapping was adjusted for the new layout.

MINOR

AB 670 transitioned from its amended-in-Senate version to enrolled status, meaning it passed both chambers and was sent to the Governor. The substantive change is the removal of a reporting provision in Section 1.5 (the AB 726 incorporation section) that would have allowed planning agencies to count rehabilitated deed-restricted affordable housing units at 45 percent or less of area median income, at least 15 years old, with at least $60,000 per unit in local rehabilitation funds. The remaining changes are formatting updates associated with the enrolled bill format and a correction to an office name.

REQUIREMENT

Removed paragraph (v) from Section 1.5 that would have authorized planning agencies to include in their annual housing element report the number of existing deed-restricted affordable housing units at 45 percent or less of area median income that are at least 15 years old and substantially rehabilitated with at least $60,000 per unit in local funds. This removed a pathway for counting older rehabilitated affordable units toward housing production goals.

TECHNICAL

In Section 1.5, the office name was corrected from 'Office of Planning and Research, Land Use and Climate Innovation' to 'Office of Land Use and Climate Innovation,' reflecting the current name of the state agency.

MODERATE

This amendment primarily restructures the bill to explicitly amend Government Code Section 65400 (referencing its prior amendment by Chapter 22 of the Statutes of 2025) rather than only adding a new Section 65400.3. The annual housing reporting requirements are now codified directly within Section 65400. Minor drafting errors were also corrected, including removing a duplicated word ('demolished demolished') and a stray phrase ('and whether process').

TECHNICAL

The bill now includes an explicit 'SECTION 1' that amends Government Code Section 65400 to incorporate all annual housing element reporting requirements directly into that section, rather than having them appear only as new standalone text. This clarifies the legal structure of where the reporting obligations are codified.

Fixed a drafting error in subsection (C) by removing the stray phrase 'and whether process' from the description of ministerial vs. discretionary approval processes, and changed 'including whether both of the following' to 'including both of the following.'

Corrected typos in the bill summary: 'demolished demolished' changed to 'demolished' and 'would would' changed to 'would.'

Updated the amendment date from June 23, 2025 to August 29, 2025, with the earlier date retained as a secondary line.

MODERATE

AB 670 was amended to add a new fallback section (SEC. 1.5) that provides an alternative version of the housing reporting requirements in case companion bill AB 726 is not enacted first. The amendment also adds two new reporting categories: one for substantially rehabilitated deed-restricted affordable housing units and another for projects under Section 65913.16. These changes expand the scope of data local governments must report annually about housing production and rehabilitation.

SCOPE

A new SEC. 1.5 was added that amends Section 65400 without reference to AB 726's prior amendments, creating a fallback version operative only if AB 726 is not enacted before this bill. The legislative counsel's digest now notes this dual-track approach.

REQUIREMENT

A new reporting clause (v) in the fallback section allows local governments to report units of existing deed-restricted affordable housing at or below 45 percent of area median income that are at least 15 years old and have been substantially rehabilitated with at least $60,000 per unit in local funds (including debt forgiveness). These units would not count toward affordability requirements under Section 65913.4.

A new paragraph (O) was added to the main section requiring annual reporting on housing development projects under Section 65913.16, including the number of applications submitted, locations and numbers of approved developments, building permits issued, and total units constructed by income category.

TECHNICAL

The replacement housing report language was slightly reworded from 'the replacement units' anticipated completion date' to 'the anticipated completion date of the replacement units.' Page numbering was corrected from 96 to 95.

MODERATE

The Senate amendment adds a phased implementation timeline, delaying several new reporting requirements until the report due by April 1, 2027, and removes the requirement that converted affordable housing units must have been converted with committed assistance. These changes give local governments more time to build data systems for demolition tracking, replacement housing reporting, and converted unit reporting, while making it easier for jurisdictions to count deed-restricted conversions toward their housing element compliance without needing to demonstrate public funding was involved.

TIMELINE

Multiple new reporting requirements are delayed until the report due by April 1, 2027. These include: demolition of housing units reports (paragraph O), replacement housing unit reports for non-housing development projects (paragraph P), tracking whether applications are subject to replacement housing or relocation assistance obligations (paragraph C(ii)), and inclusion of total replacement housing units by income level in the production report (subparagraphs H(i)(III) and H(i)(IV)).

The provision allowing planning agencies to count converted affordable units (up to 25 percent of their regional housing need allocation for low, very low, extremely low, or acutely low income households) toward their housing element is delayed until the report due by April 1, 2027.

ELIGIBILITY

The requirement that a converted unit must have been 'converted with committed assistance' to qualify for counting toward housing element compliance (former Section 65400.3(c)(5)) is removed. This lowers the bar for jurisdictions to count existing multifamily units converted to deed-restricted affordable housing without needing to demonstrate public funding was committed to the conversion.

TECHNICAL

Paragraph (C) of the annual report requirements is restructured from a single combined provision into two sub-paragraphs: (i) for ministerial vs. discretionary approval process information, and (ii) for replacement housing or relocation assistance obligation tracking (with the 2027 delay).

MINOR

The amendment makes two minor technical corrections: it updates the name of a state agency from 'Office of Planning and Research, Land Use and Climate Innovation' to 'Office of Land Use and Climate Innovation' (reflecting the 2024 statutory rename of OPR), and fixes a duplicated word ('process. process') in the reporting requirements. No substantive policy changes were made.

TECHNICAL

Updated the agency name from 'Office of Planning and Research, Land Use and Climate Innovation' to 'Office of Land Use and Climate Innovation' to conform to the 2024 statutory renaming of the Office of Planning and Research.

Corrected a drafting error where the word 'process' was duplicated ('process. process') in the housing development application reporting requirement, changing it to a single 'process.'
