SB 283 (Clean Energy Safety Act of 2025) creates statewide procedural requirements for battery energy storage projects by forcing applicant engagement with fire authorities, requiring a post‑installation fire inspection before operation, and directing the Office of the State Fire Marshal (OSFM) to pursue building‑code changes that could limit indoor installations. The bill applies to projects submitted after January 1, 2026, and places inspection costs on project applicants.
Why this matters: the measure inserts fire officials formally into the permitting and certification pathway for energy storage, gives the Energy Commission and local jurisdictions a new conditional step before systems can operate, and initiates a near‑term code review that could reshape where new large batteries may be sited. Developers, local permitting staff, and fire agencies will see new process requirements and potential timing and cost impacts when siting systems in California.
At a Glance
What It Does
Requires applicants to document that they met and conferred with the local authority having jurisdiction over fire suppression at least 30 days before filing a certification or local permit application, and requires a fire‑authority inspection after installation but before operation. The bill also directs OSFM to review and consider proposals to limit indoor installations as part of the next building‑code update after July 1, 2026.
Who It Affects
Large projects routed to the State Energy Resources Conservation and Development Commission (Energy Commission) and local battery projects subject to local permitting (the bill defines local systems as 10 MWh or greater), local fire authorities and inspection staffs, project developers and owners who must pay inspection costs, and the OSFM during the code review process.
Why It Matters
The law creates a mandatory, documentable consultation step and an inspection gate before operation, which can add time and cost to project schedules and elevate fire officials’ influence over siting and emergency planning. The OSFM’s code review could lead to location restrictions that materially affect project design, cost, and land use decisions.

What This Bill Actually Does
SB 283 layers a fire‑safety centric process onto California’s existing approval tracks for stationary battery energy storage. For projects that must seek Energy Commission certification (per existing Section 25545 references) and for projects seeking local permits, the bill requires applicants to certify they met and conferred with the local fire authority at least 30 days before filing.
The application must include documentation of that consultation—who attended, when, what safety topics were discussed, and how the project design or emergency plans respond to the issues raised.
The bill gives the fire authority a short, defined window to engage: 30 days to respond to a meeting request and a directive that the meeting occur within 60 days unless both parties agree otherwise. If a fire authority declines to meet or does not respond, applicants may still submit their application but must document those interactions.
After installation is complete, the fire authority must inspect the installation before the system begins operation; applicants pay the inspection cost. For Energy Commission cases, if the inspection has not happened within 90 days of the applicant’s notice of completion, the commission may nonetheless certify the project.Separately, SB 283 adds a Public Utilities Code chapter that defines “energy storage system” for local permitting purposes as a stationary system capable of storing 10 MWh or more.
That chapter requires cities and counties to make inspections a condition of approval and to accept the same consultation documentation that state certification requires. The bill also directs OSFM to review (in the next building‑code update after July 1, 2026) whether to propose provisions that would restrict energy storage to dedicated‑use noncombustible buildings or outdoor installations, and to consider different rules by battery chemistry or flammability profile; that directive sunsets January 1, 2029.
Local jurisdictions may adopt rules that are at least as protective as the state requirements.
The Five Things You Need to Know
Applicants must attest in their application that they met and conferred with the fire authority at least 30 days before filing and must include a dated consultation record with participant names, topics discussed, and how the project addresses those topics.
The fire authority has 30 days to respond to a meeting request and the meeting must occur within 60 days of the request unless the parties agree otherwise; if the authority declines or fails to respond the applicant documents the outreach and may proceed.
After installation, the energy storage system must be inspected by the fire authority before beginning operations; the applicant bears inspection costs and, if the inspection hasn’t occurred within 90 days after notice of completion, the Energy Commission may still certify the project.
For local permitting, SB 283 defines an energy storage system as 10 MWh or greater and requires local jurisdictions to condition approval on the post‑installation inspections and to accept the same consultation documentation.
OSFM must review and consider proposing code changes—after July 1, 2026—that could limit indoor installations to dedicated‑use noncombustible buildings or require outdoor installations, may differentiate by battery technology, and that review authority expires January 1, 2029.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Post‑installation fire inspection requirement and timing
This provision bars Energy Commission certification of an energy storage system unless the fire authority inspects the installation within 90 days of the applicant’s notice of completion and before operation, and requires the applicant to pay the inspection cost. Practically, the commission must document compliance in its certification decision, but it also retains a fallback: if the inspection hasn’t occurred within 90 days, the commission may still certify. That creates a hard deadline for local inspection capacity while preserving the commission’s ability to avoid indefinite project holds.
Pre‑application consultation with fire authority and documentation
This section forces applicants seeking Energy Commission certification to meet and confer with the local fire authority at least 30 days before filing, to solicit input on design, mitigation, and emergency action plans, and to include a written record of the consultation in the application. It also sets response and meeting windows (30‑day response; meeting within 60 days) and creates a documented fallback if the fire official declines or doesn’t respond. The provision makes the consultation a discrete, auditable step in the state certification record.
Local threshold and basic definitions
Chapter 10 defines a local 'energy storage system' for the purposes of this chapter as a stationary system capable of storing 10 MWh or more, and defines 'local jurisdiction' to mean city, county, or city‑and‑county. That lower threshold is important because it captures projects that may not trigger state Energy Commission certification but are large enough to present community and fire‑safety risks, bringing them into the bill’s consultation and inspection framework at the local level.
Local permit application content and inspection condition
Section 8501 requires local permit applications for covered systems to include the same 30‑day pre‑application consultation certification and documentation required at the state level. Section 8502 obligates local jurisdictions to make post‑installation inspection by the authorities having jurisdiction—including the fire authority—a condition of approval and to require the applicant to pay inspection costs. These sections operationalize the consultation and inspection model at the municipal level and bind local permitting processes to those steps.
OSFM building‑code review and potential location limits (sunset)
This section directs the OSFM, in the next building‑code update after July 1, 2026, to review and consider proposing provisions that would restrict energy storage locations to dedicated‑use noncombustible buildings or outdoor installations. The OSFM must limit its proposals to fire and life‑safety considerations in the building‑code process, may differentiate by battery chemistry/flamability, and the directive expires on January 1, 2029. The provision therefore starts a near‑term pathway for potential structural and siting constraints without immediately changing the code.
Local authority preserved; statewide concern finding
Section 8504 clarifies that local jurisdictions may adopt laws that are as protective or more protective than the chapter. The act also contains a legislative finding that battery safety is a matter of statewide concern and applies the statute to all cities, including charter cities, and includes a provision that no state reimbursement is required because local fees can cover the mandated services.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Local fire authorities and first responders — gain formalized early access to project design and emergency plans and a mandated inspection gate that can improve preparedness and reduce on‑scene surprises.
- Neighbors and local communities near storage sites — benefit from documented consultation, clearer emergency plans, and the prospect of stricter siting rules (e.g., outdoor or noncombustible buildings) that lower fire risk.
- Vendors and developers of lower‑risk battery chemistries and packaged noncombustible enclosures — may gain market advantage if OSFM proposals favor technologies with better flammability profiles.
- Local permitting bodies — obtain a standardized, statewide procedural floor (documentation and inspection requirements) that can reduce discretionary variation across jurisdictions.
Who Bears the Cost
- Project applicants and system owners — must pay for pre‑application outreach, produce documentation, and cover inspection fees; potential redesigns or relocations driven by future code changes could add construction costs.
- Local fire departments and inspection staffs — face increased inspection and consultation workload without dedicated funding, which could strain capacity in jurisdictions with thin staffing.
- Energy Commission and local permitting agencies — must incorporate compliance findings into certification and approval records, adding administrative steps and potential delay oversight.
- Building owners and hosts of installations — could face retrofit or siting constraints if OSFM proposals push systems into dedicated noncombustible or outdoor locations, raising land‑use and capital costs.
Key Issues
The Core Tension
The central dilemma SB 283 confronts is safety versus speed: California needs more energy storage for grid decarbonization and resilience, but the bill increases fire‑safety oversight in ways that can delay projects, raise costs, and strain local fire resources—choosing greater procedural and siting caution risks slowing deployment that the state otherwise prioritizes.
SB 283 tries to thread safety into the storage deployment pipeline, but it leaves several operational and policy questions unresolved. The bill mandates consultation and inspections but does not fund the additional workload imposed on local fire authorities; those agencies vary widely in capacity across California, so the 90‑day inspection expectation could work in suburban counties but become a bottleneck in under‑resourced areas.
The Energy Commission’s authority to certify a project if the inspection hasn’t occurred within 90 days avoids indefinite project freezes, but it also creates a potential safety trade‑off: projects could begin operation without a completed local inspection if staffing or scheduling problems persist.
The bill also establishes two different size thresholds: the Energy Commission references existing law (which historically targeted much larger, e.g., 200 MWh, eligible facilities) while Chapter 10 sets a 10 MWh threshold for local permitting—an intentional expansion that captures mid‑sized projects but also creates a two‑track regulatory reality. The OSFM’s temporary directive to consider restricting indoor installations introduces short‑term uncertainty for developers: code changes could materially alter project design, but that review is limited to fire and life‑safety framing and sunsets in 2029.
Finally, the statute relies on application documentation of “meet and confer” without defining minimum substantive outcomes, which leaves room for uneven implementation and potential disputes about what counts as adequate consultation.
