AB 2366 amends Government Code Section 11346.5 to widen what state agencies must include in notices of proposed regulatory action. The bill requires an informative digest drafted in plain English (modeled on the Legislative Counsel’s digest), expanded policy statements that identify nonmonetary benefits, detailed cost and savings estimates prepared under Department of Finance instructions, and explicit findings about impacts on businesses and housing costs.
It also codifies what must be made available to the public and preserves a ‘‘substantial compliance’’ safe harbor for notice defects.
The change matters because it raises the bar for the informational content agencies must prepare before adopting, amending, or repealing regulations. Compliance officers, agency rule writers, regulated industries, and local governments will need to budget analytic time and legal review earlier in the rulemaking cycle.
At the same time, advocates and affected parties gain clearer, standardized materials to evaluate proposed rules, challenge assumptions, and propose less burdensome alternatives.
At a Glance
What It Does
The bill expands the required content of notices of proposed action to include a plain‑English informative digest, a policy overview addressing nonmonetary benefits, standardized cost and savings estimates (including federal funding effects), and explicit statements about potential statewide economic effects on business and housing costs. It also requires agencies to disclose supporting records and provides procedural contact and comment details.
Who It Affects
State agencies that draft regulations must produce more extensive analyses and plain‑language materials. Local agencies, school districts, and businesses are affected through expanded cost‑reimbursement and impact disclosures. Advocacy groups, planners, and housing stakeholders gain new avenues to request housing‑cost evaluations.
Why It Matters
The bill standardizes and elevates transparency in California rulemaking, shifting analytical work earlier in the process and creating clearer records for public review and legal challenge. That increases predictability for some stakeholders but raises administrative workload and potential interagency coordination costs.

What This Bill Actually Does
AB 2366 rewrites what must appear in the notice that agencies send when they propose a regulation. The notice must now include an informative digest written in plain English similar in format to the Legislative Counsel’s legislative digest; that digest must summarize related existing law, explain how the proposal differs from comparable federal rules when relevant, and outline the broad objectives and anticipated benefits of the proposal, including nonmonetary public‑interest benefits such as health, safety, equity, or transparency.
The bill tightens economic disclosure requirements. Agencies must prepare cost or savings estimates according to Department of Finance instructions and identify costs that state agencies, local governments, and federal funding will experience.
If an agency initially determines a proposal may have a significant statewide adverse economic impact on business, the notice must list affected business types, describe new reporting or compliance duties, and publish a standard invitation for alternative proposals (for example, different timetables, consolidation of reporting, use of performance standards, or exemptions). Conversely, when the agency declares no significant impact, it must place supporting evidence in the rulemaking record.AB 2366 also adds focused requirements around housing: if an agency determines a proposed action would significantly affect housing costs, the notice must say so and the agency must make any housing‑cost evaluation available on request.
For model codes adopted under Health and Safety Code Section 18928, the housing‑cost analysis is required only if an interested party asks the agency to examine a specific code section. The bill preserves practical access requirements—contact names, comment deadlines, availability of proposed text and supporting records, how to get final statements of reasons, and accommodations for persons with disabilities—and it closes with a ‘‘substantial compliance’’ clause to avoid invalidating a regulation solely for technical deficiencies in notice content.
The Five Things You Need to Know
The notice must include an informative digest in plain English that summarizes existing law, explains the effect of the proposal, and notes significant differences from comparable federal law with full citations.
Cost and savings estimates must follow Department of Finance instructions and cover direct and indirect additional costs that public agencies necessarily incur in reasonable compliance, plus effects on federal funding to the state.
If an agency initially finds a proposal may have significant, statewide adverse economic impacts on business, the notice must identify affected business types, list projected reporting and compliance duties, and invite specific alternative proposals (timelines, consolidated reporting, performance standards, or exemptions).
When an agency determines a proposed action would significantly affect housing costs it must state that in the notice and make any evaluation of housing‑cost impacts available to the public upon request; model code analyses are triggered only by a stakeholder request for a specific section.
Section (c) protects regulations from being invalidated for alleged notice inadequacies provided the agency has ‘‘substantial compliance’’ with the bill’s notice and summary requirements.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Core notice basics and authority citation
These paragraphs retain the baseline notice elements: time, place, nature of proceedings, and the statutory authority being implemented. Practically, they require agencies to tie every regulatory proposal clearly to the enabling statute or legal provision so readers can quickly see legal grounding. That linkage is central to later judicial review and public comment because it anchors cost‑benefit and alternatives analysis to the authorizing law.
Plain‑English informative digest and policy overview
This provision obligates agencies to produce a concise, plain‑language digest modeled on legislative digests, including an overview of existing law, the proposal’s effect, and a policy statement describing anticipated benefits. Importantly, the digest must enumerate nonmonetary benefits—public health, worker safety, equity, transparency, anti‑discrimination effects—making agencies explicate qualitative goals alongside quantitative ones. For rule writers, this shifts some policy justification into the public notice itself rather than burying it only in internal memos or the statement of reasons.
Mandates and standardized cost/savings estimates
Agencies must state whether a regulation imposes a mandate on local agencies or school districts and, if so, whether the mandate requires state reimbursement. The bill also mandates cost or savings estimates prepared per Department of Finance instructions, covering state agency costs, reimbursable local costs, non‑discretionary local costs, and federal funding impacts. The ‘‘cost or savings’’ definition explicitly includes additional direct and indirect costs that a public agency necessarily incurs in reasonable compliance, which narrows arguments that only narrowly defined accounting items count as costs.
Business‑impact findings and economic analysis disclosure
When an agency initially determines that a proposal may have significant, statewide adverse impacts on business, the notice must identify affected business types, describe reporting and compliance burdens, and include a standard invitation for alternatives that reduce burdens. If the agency instead declares no significant impact, the record must include evidence supporting that conclusion. Agencies must also attach the results of the economic impact assessment or standardized regulatory impact analysis and summarize comments and agency responses, creating a tighter paper trail for later administrative or judicial scrutiny.
Housing‑cost disclosure rules
Agencies that initially determine a proposed action would significantly affect housing costs must say so in the notice and provide, on request, whatever evaluation they have prepared of those housing effects. For model codes under Health and Safety Code Section 18928, the housing‑cost analysis duty is limited to situations where an interested party asks the agency to examine a specific section, narrowing the scope but creating an on‑demand review obligation that can trigger additional analysis and comment.
Alternatives finding, public access, and administrative logistics
The bill requires the agency to state that no reasonable alternative is preferable and to base significant‑regulation findings partly on standardized impact analyses and benefit statements. It also codifies operational items: contact names and backup contacts, comment deadlines, availability of the statement of reasons and supporting records, instructions for requesting public hearings, availability of revised full text before adoption, and accommodations for persons with disabilities. Paragraph (b) further requires the designated agency representative to make express terms and locations of records available on request or refer inquiries promptly—tightening citizen access to the materials they need to comment effectively.
Substantial compliance safe harbor
This clause prevents automatic invalidation of a regulation for alleged inadequacy of notice details if the agency has substantially complied with the content requirements. That creates a procedural buffer for agencies but leaves open litigation over what ‘‘substantial compliance’’ means in practice—so agencies should still aim for thoroughness to reduce risk of challenge.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Residents and consumer advocates — gain clearer, plain‑English digests and explicit housing‑cost disclosures that make it easier to evaluate a regulation’s practical effects and mobilize targeted comments or legal challenge.
- Local governments and school districts — receive clearer determinations about whether a regulation imposes a reimbursable mandate and more transparent cost estimates that help budget projections and reimbursement claims.
- Businesses and trade associations — get earlier identification of potential compliance and reporting burdens along with an explicit channel to propose less burdensome alternatives (timelines, consolidation, exemptions, or performance standards).
- Housing advocates and planners — can request and obtain housing‑cost evaluations for proposed regulations, improving the evidentiary basis for comments on proposals that affect housing affordability.
- Transparency and public‑interest groups — benefit from standardized economic impact documents and summarized agency responses, which make it easier to monitor whether agencies are weighing alternatives and nonmonetary benefits.
Who Bears the Cost
- State agencies that propose regulations — must draft plain‑English digests, prepare standardized cost/savings estimates per Department of Finance instructions, compile housing analyses on request, and maintain responsive records and contacts, increasing analytic, legal, and administrative workload.
- Department of Finance — faces expanded demand to provide instructions and potentially to review or reconcile agency estimates, which could require new guidance or staff time.
- Small regulatory units within state agencies — may lack capacity for the required economic and housing analyses and will likely need to buy external consultants or reassign staff time.
- Businesses and regulated entities — while the bill invites alternatives, firms may still face new reporting, recordkeeping, or compliance obligations that appear in notices and are implemented in final rules, raising operational costs for affected sectors.
- Interested parties who request housing evaluations or sections of model codes — may trigger additional agency analyses that lengthen rulemaking timelines and lead to more contested records.
Key Issues
The Core Tension
The central tension is between two legitimate goals: strengthen transparency and public participation by forcing agencies to produce clearer, evidence‑based notices versus the practical cost and delay of producing those analyses. Increasing disclosure improves oversight and gives stakeholders concrete levers to reduce regulatory burden, but it also raises administrative costs and may slow the adoption of rules designed to protect health, safety, or the environment.
The bill increases transparency but does so by shifting analytic burdens earlier in the rulemaking timeline. Producing a plain‑English digest that meaningfully explains tradeoffs, assembling standardized cost estimates that capture indirect and federal funding impacts, and preparing housing‑cost evaluations on request all require time, expertise, and interagency coordination.
Smaller agencies and rule teams may struggle to meet these requirements without additional funding or centralized support, creating a potential mismatch between legislative expectations and administrative capacity.
Several implementation ambiguities could drive litigation or inconsistent practice. ‘‘Substantial compliance’’ protects agencies from hypertechnical invalidation, but courts will decide its contours. The requirement to declare ‘‘no significant, statewide adverse economic impact’’ and place supporting evidence in the record raises the evidentiary bar—good for transparency but likely to produce more administrative records and contested factual disputes.
The housing‑cost disclosure is targeted but leaves open whether cursory or robust analyses satisfy public demand; for model codes it is request‑triggered, which helps limit workload but also allows parties to force focused, potentially costly reviews of discrete code sections.
