SB 131 and SB 158 CEQA housing rules

SB 131, Chapter 24, took effect immediately on June 30, 2025. It added a CEQA rule for housing-element rezonings, a limited-review rule for certain housing projects that miss an exemption by one condition, definitions used by those provisions, and a farmworker housing provision.

SB 158, Chapter 650, took effect immediately on October 11, 2025. It amended the housing framework, including Public Resources Code sections 21067.5, 21080.1, and 21080.66, and moved the farmworker housing text from section 21080.44 to section 21080.45.

For current work, start with the current Public Resources Code. Use the two chaptered bills to explain the history, not as substitutes for the operative text. This guide is a source map and fact-record template, not an eligibility determination. Under section 21080.1(a), the lead agency determines whether a project is exempt and which environmental document, if any, is required.

Start with the housing question

The statutes answer different questions. Keep the candidate paths separate until the project facts and each cross-reference are documented.

Housing question	Current section to open	First facts to collect
Does a rezoning implement the schedule of actions in an approved housing element?	PRC § 21080.085	Approved housing element, scheduled action, rezoning text and map, boundaries, allowed uses, and natural-and-protected-lands overlays
Would a housing development project otherwise fit a specified exemption but for one condition?	PRC § 21080.1(b)	Exact exemption, project type, every possible disqualifying condition, causation evidence, site and parcel area, and excluded land or use facts
Is the project being screened under the broader housing-development exemption?	PRC § 21080.66	Project definition, acreage, location and urban context, plan and zoning facts, density, historic-resource facts, consultation, site assessment, freeway proximity, labor, and notice records
Is the work new agricultural employee housing or only repair or maintenance of existing farmworker housing?	PRC § 21080.45	Project scope, funding and ownership, and each incorporated Health and Safety Code and PRC condition
Do the project and parcel have the unusual location, wetland, floodway, and historic-adjacency facts listed in the statute?	PRC § 21080.73	2020 Census population facts, parcel boundaries, official wetland and floodway maps, and the adjacent landmark record

This is a research sequence, not a list of alternative outcomes. A project may require review under other statutes and regulations that are outside this SB 131 and SB 158 housing search.

Housing-element rezoning: section 21080.085

Section 21080.085 says CEQA does not apply to a rezoning that implements the schedule of actions in an approved housing element. The section does not apply to a rezoning that would allow construction of a distribution center or oil and gas infrastructure, or that would allow construction within natural and protected lands as defined in section 21067.5.

The statute also addresses a rezoning boundary that contains natural and protected lands. It allows the protected land to be excluded from the rezoning, subject to the section’s exact treatment of farmland in section 21067.5(p), and makes any excluded parcel or parcel portion a separate project subject to CEQA.

HCD’s May 19, 2026 memorandum, CEQA Reforms for Housing Element Rezoning, explains the agency’s reading of the provision. HCD explains that an approved housing element is one it has found substantially compliant or to meet the statutory requirements of Housing Element Law. The memorandum also explains why an element that missed a rezoning deadline may meet those statutory requirements without yet being substantially compliant. It also explains that a qualifying rezoning can include zoning-map changes, zoning-text amendments, and general-plan amendments needed for consistency. Read the memorandum with the current statute and the adopted local record.

For the file, preserve:

the adopted housing element, HCD compliance letter, adoption date, and amendment history;
the exact schedule-of-actions language and the action it commits the jurisdiction to take;
the proposed ordinance, zoning text, map, general-plan amendment, parcel list, and legal description;
a before-and-after list of allowed uses, including any distribution-center or oil-and-gas-infrastructure use;
the source, version, retrieval date, and geometry for every natural-and-protected-lands check; and
any excluded parcel or parcel portion, with a map and an explanation of how the separate project will be handled.

Do not reduce the record to a label such as “housing-element rezoning.” The link between the approved schedule of actions and the exact rezoning is a fact that should be visible in the file.

One-condition review: section 21080.1(b)

Section 21080.1(b) addresses a proposed housing development project that would otherwise be exempt under a statutory exemption, or under categorical Class 1 through 5, 12, 15, 20, 27, 30, or 32 adopted before January 1, 2026, but for a single condition specified in the exemption or listed CEQA Guidelines provisions. For a project within that rule, the statute limits CEQA’s application to environmental effects caused solely by that one condition.

An initial study or EIR under this subdivision examines the effects that the lead agency determines, based on substantial evidence in the record, are caused solely by the condition. An EIR under the subdivision need not discuss project alternatives or growth-inducing impacts.

The rule does not apply when the project is not similar in kind to the projects described by the exemption, when two or more conditions make it ineligible, when it includes a distribution center or oil and gas infrastructure, or when it is on natural and protected lands as the subdivision defines that term. SB 158 also added a four-acre exclusion for the builder’s-remedy and pre-2025 application circumstances stated in section 21080.1(b)(4)(E).

A useful record separates four things that are easy to collapse:

The exemption text. Save the exact statutory or categorical exemption and every incorporated Guidelines section used in the screen.
The project comparison. Record why the proposed housing development is or is not similar in kind to the projects described by that exemption.
The condition count. List each physical feature, regulatory feature, setting fact, or environmental effect considered under the statute’s definition of “condition.” Do not call the case a one-condition case before documenting other possible conditions.
The effect connection. Identify the evidence the lead agency used to determine which environmental effects are caused solely by the condition.

Also record the project-site area, parcel area, Housing Accountability Act status and dates when relevant, every nonhousing use, and the current section 21067.5 overlay results. These facts correspond to express limits in the current statute.

Housing-development projects: section 21080.66

Section 21080.66 is a separate housing-development exemption with an all-conditions structure. SB 158 amended it on October 11, 2025. The current text addresses the housing development and its required permits, approvals, and public improvements when every stated condition is met.

Do not treat section 21080.66 as a short acreage test. Its current record spans:

the applicable definition of “housing development project” in Government Code section 65905.5(b);
the project-site and parcel areas, including the four-acre rule for the builder’s-remedy and earlier-application circumstances named in the section;
location within an incorporated municipality or Census-defined urban area, plus the applicable urban-use context test;
general-plan, zoning, local coastal program, density, and Government Code cross-reference facts;
historic-register and transient-lodging facts;
tribal notice, consultation, agreements, and binding conditions;
the phase I environmental assessment and any follow-on hazardous-substance work;
the 500-foot freeway check and the specified building measures when it applies;
applicable labor records; and
the notice of exemption filed with the Governor’s Office of Land Use and Climate Innovation and county clerk.

A map, plan, or conclusion should identify its source and date. A statutory cross-reference should be opened and recorded, not replaced with a checklist label.

Check the narrow section 21080.73 override

SB 158 also added section 21080.73. It states that a housing development project meeting all of its specific city and county population, mapped wetland, regulatory floodway, and historic-landmark adjacency criteria is a discretionary project and is not exempt from CEQA, notwithstanding other law.

Do not generalize this provision from a city name or a screening note. Preserve the 2020 Census figures required by the section, the project and parcel boundaries, the official wetland and floodway map records, and the California historical landmark record for the adjacent property.

The farmworker provision is now section 21080.45

SB 131 enacted the agricultural employee and farmworker housing text as section 21080.44. SB 158 amended and renumbered that same provision to section 21080.45 on October 11, 2025. A current memo or checklist should cite section 21080.45, not the former number.

Subdivision (a) addresses a new agricultural employee housing project that complies with PRC section 21159.22, meets the stated requirements in Health and Safety Code section 17021.8(i), and has one of the listed public or nonprofit funding, ownership, or operating relationships. Subdivision (b) addresses a project consisting exclusively of repair or maintenance of an existing farmworker housing project.

Preserve the project description, whether the work is new construction or exclusively repair or maintenance, each cross-referenced condition, funding documents, and ownership or operating records. The section number is only the route to those facts.

Read the defined terms in the current code

Three definitions introduced by SB 131 recur in the housing provisions:

“Distribution center,” PRC § 21060.4, means a warehouse distribution center as defined in Labor Code section 2100 that is 50,000 square feet or larger.
“Oil and gas infrastructure,” PRC § 21064.8, means a facility used for the production, processing, transmission, storage, or distribution of petroleum or natural gas.
“Natural and protected lands,” PRC § 21067.5, is a multi-part definition covering specified parks and protected areas, listed hazardous-waste sites subject to stated exceptions, regulatory floodways, conservation easements, wetlands and their 300-foot radius, coastal environmentally sensitive areas, lands identified by specified conservation plans, certain fire-hazard lands, and specified farmland.

SB 158 broadened the wording of section 21067.5(n) from preserve or reserve lands under specified plans to lands identified for conservation in those plans, and added other adopted natural resource protection plans. The current subdivision lettering matters because sections 21080.085 and 21080.1 contain different carve-outs tied to sections 21067.5(p) and 21067.5(o), respectively.

Section 21080.1 also defines “condition” for its limited-review rule and imports its definition of “housing development project” from Government Code section 65589.5. Section 21080.66 uses the definition in Government Code section 65905.5(b). Record which definition belongs to which path rather than assuming the same cross-reference applies everywhere.

The lead agency identifies the environmental document

Section 21080.1(a) assigns the lead agency responsibility for determining whether a project is exempt and, for a project subject to CEQA, whether an Environmental impact report (EIR), Negative declaration (ND), or Mitigated negative declaration (MND) is required.

Keep that determination distinct from the research screen. The record should identify the decision maker, the statute or regulation applied, the facts accepted, the evidence cited, the environmental document or exemption record selected, and the date of the determination.

A compact fact record

A review handoff should let the next practitioner retrace the analysis without reconstructing the search:

Record item	What to preserve
Project and action	Project description, housing and nonhousing components, discretionary approvals, rezoning action, site and parcel boundaries
Candidate provision	Current section and subdivision, each incorporated cross-reference, and the reason it was opened
Time	Application and completeness dates, housing-element adoption and HCD dates, decision date, and code version reviewed
Exemption comparison	Exemption text, project-type comparison, each stated condition, and every possible disqualifying fact
Location evidence	Official source, layer or map version, retrieval date, query or map extent, geometry, and any boundary uncertainty
Supporting records	Adopted plans and ordinances, staff reports, funding and ownership documents, consultation records, assessments, and notices
Agency determination	Decision maker, finding or determination, evidence cited, document selected, filing, and public link
Open questions	Missing records, unresolved map conflicts, cross-references still to verify, and the person responsible for follow-up
