AB 1455: The Emergency Legislation That Followed the LA Fires

January 2025: the fires that forced action

California had been through many devastating fire seasons since AB 3074 passed in 2020. But none hit quite like the fires of January 2025. On January 7, the Palisades Fire ignited in Pacific Palisades, driven by powerful Santa Ana winds. Within hours it had spread across thousands of acres, racing through the canyons and hillsides above one of Los Angeles's most affluent coastal communities. Around the same time, the Eaton Fire broke out near Altadena, northeast of Pasadena, burning through another densely populated urban-wildland interface neighborhood.

Together, the two fires destroyed approximately 16,000 structures (some estimates put the number higher) and killed dozens of people. The destruction swept through neighborhoods that had never experienced wildfire at this scale: streets of mid-century homes, apartment buildings, commercial districts, schools. The fires cut through the urban fabric of Los Angeles in ways that challenged long-held assumptions about which neighborhoods were and weren't at risk.

The fires also occurred against a backdrop of intense public frustration about California's wildfire preparedness. Insurance companies had spent years pulling out of the California market or dramatically raising premiums in high-risk areas. Defensible space compliance rates remained low in many communities. And Zone Zero, the specific policy designed to address the ember-driven ignition mechanism most responsible for urban wildfire destruction, had still not been implemented five years after AB 3074 passed.

The accountability moment

In the days and weeks after the Palisades and Eaton fires, media coverage zeroed in on a specific regulatory failure: Zone Zero regulations were not in effect. The California Board of Forestry and Fire Protection had been working on the rulemaking since 2021. Public workshops had been held. Draft language had been developed. But final, enforceable regulations had not been adopted, and the deadline originally established by AB 3074 had come and gone without action years earlier.

The Oakland Firesafe Council published a detailed analysis documenting the sequence of events: how the Zone Zero Advisory Committee had come close to completing its work by fall 2025, how near-final language had been on the table, and how the December 31, 2025 deadline had passed without adoption. The analysis noted that the delay was no longer about science, but about process, oversight, and political will.

Representative Laura Friedman, who had authored AB 3074 while in the California State Assembly and was now serving in Congress, marked the one-year anniversary of the LA fires in January 2026 with a statement remembering the victims and calling for continued action. The fires she had tried to prevent through legislation had, in her own district and neighboring communities, done exactly the kind of damage her bill was designed to reduce.

Executive Order N-18-25

On February 6, 2025, Governor Gavin Newsom issued Executive Order N-18-25, directing the State Board of Forestry and Fire Protection to complete the formal rulemaking process for Zone Zero defensible space regulations no later than December 31, 2025. The executive order was issued just weeks after the Palisades and Eaton fires and represented the Governor's most direct intervention in the Zone Zero rulemaking process to date.

The order directed the Board to accelerate its work and established a hard deadline. It also signaled clearly, for the first time from the executive branch, that the years of slow-moving committee work were no longer acceptable. California had waited five years. The LA fires had demonstrated, in the most direct and devastating way possible, what the cost of continued delay looked like.

Representative Friedman welcomed the order directly: “It's past time we get these commonsense rules written and shared with the public. Not only will they help protect homes from wildfires, but they will help lower costs for homeowners and renters by lowering insurance rates. It's good that Governor Newsom is signing an executive order ensuring my legislation to protect our families is finally implemented.” The executive order set the stage for the legislative response that would become AB 1455.

Assemblymember Bryan's bill

Assembly Bill 1455 was introduced in the 2025-2026 legislative session by Assemblymember Isaac Bryan, representing California's 55th Assembly District in Los Angeles. Bryan's district included communities in South Los Angeles and Culver City, not the fire-prone hillside neighborhoods that had borne the brunt of the January 2025 fires, but communities deeply affected by the regional emergency and by the broader crisis of insurance availability and wildfire risk that shaped life across greater Los Angeles.

The bill's full title was: “State Board of Forestry and Fire Protection: defensible space requirements: ember-resistant zones: emergency regulations: California Environmental Quality Act.” Its primary purpose was straightforward: authorize the Board of Forestry to adopt Zone Zero regulations on an emergency basis, bypassing the normal notice-and-comment rulemaking timeline under California's Administrative Procedure Act.

Under normal administrative rulemaking, California agencies must follow a process that includes filing proposed regulations with the Office of Administrative Law, publishing them for public comment, holding hearings, responding to comments, and then submitting final regulations for review. This process typically takes six months to a year and is specifically designed to prevent hasty regulatory action. AB 1455 would authorize the Board to significantly compress this timeline by using the emergency rulemaking provisions that California law allows in response to genuine public safety crises.

What AB 1455 does

AB 1455 amended Section 51182 of the Government Code and added a new Section 51182.4, which specifically authorized emergency rulemaking. In practical terms:

Authorized emergency rulemaking. The bill gave the Board explicit authority to adopt Zone Zero regulations as emergency regulations under Government Code Section 11346.1, which allows state agencies to bypass normal public comment requirements when immediate action is necessary to protect the public peace, health, safety, or general welfare.

Reinforced the uniform safety standard goal. AB 1455 reinforced the legislative goal of a single, uniform safety standard across high-risk wildfire areas, pushing back against proposals that would allow significant local variation that might weaken the core Zone Zero requirements.

Maintained the three-year existing-structure timeline. AB 1455 preserved SB 504's three-year compliance window for existing structures while also moving up the effective date for certain structures in the State Responsibility Area, a targeted acceleration for properties in the highest-risk zones.

Addressed the CEQA interface. One of the bill's technical provisions addressed the California Environmental Quality Act (CEQA) review process for Zone Zero regulations, clarifying that the emergency rulemaking process could proceed without triggering a full CEQA review that might have introduced additional delays.

Interacted with SB 326. AB 1455 was drafted in coordination with Senate Bill 326, which addressed parallel wildfire safety building standards. The two bills included cross-reference provisions to ensure their amendments to Public Resources Code Section 4291 were operative together correctly if both were enacted.

The urgency clause and why it mattered

AB 1455 included an urgency clause, a provision that allowed the bill to take effect immediately upon the Governor's signature rather than on January 1 of the following year. Under California's constitution, urgency statutes require a two-thirds vote in both chambers, a higher threshold than the simple majority required for regular legislation.

The urgency clause was critical because of the timing. Executive Order N-18-25 had directed the Board to complete rulemaking by December 31, 2025. Without an urgency clause, the bill's provisions authorizing emergency rulemaking would not take effect until January 1, 2026, after the executive order's deadline had already passed. The Senate Rules Committee analysis of the bill explicitly noted this problem and the urgency clause was added as a result.

The urgency clause was added. The bill was structured so that its provisions would take effect immediately upon signing, ensuring that the Board's emergency rulemaking authority was legally in place before the December 31, 2025 deadline arrived. This was a sophisticated piece of legislative drafting that reflected the intense pressure the legislature was under to move quickly without creating legal ambiguity about the Board's authority.

Passage

AB 1455 moved through the California legislature with the urgency that its urgency clause implied. The post-LA fires political environment had created a new level of legislative intensity around wildfire issues. The fires had affected communities across the political spectrum, wealthy coastal enclaves and working-class neighborhoods alike, and had stripped away any remaining complacency about the adequacy of existing protections.

The bill was signed by Governor Newsom in 2025, becoming effective immediately. It was cited alongside AB 3074, SB 504, and Executive Order N-18-25 in subsequent Board of Forestry communications as one of the core directives governing the Zone Zero rulemaking process. The April 2026 Board of Forestry press release on its updated draft regulations specifically identified all four sources of legislative and executive authority: “Directed by first-of-its-kind legislation including Assembly Bill 3074 (2020), Senate Bill 504 (2024), Assembly Bill 1455 (2025), and Governor Gavin Newsom's Executive Order N-18-25 in early 2025.”

The December deadline passes again

Despite the executive order, the emergency rulemaking authorization, and the political pressure of the post-LA fires moment, December 31, 2025 came and went without final Zone Zero regulations being adopted. The Zone Zero Advisory Committee had continued its public workshops through the fall. By October and November, near-final language was on the table. But the process did not reach completion.

The Oakland Firesafe Council documented what happened in those final months. In the public comment sessions, there was strong, consistent support for strict Zone Zero standards from firefighters, wildfire scientists, FireSafe and Firewise leaders, IBHS, and the California Insurance Commissioner. And there was increasingly vocal opposition from Southern California homeowners and landscaping interests, focused not on the statutory authority or the fire science but on preserving vegetation and aesthetics close to structures.

The tension between scientific clarity and political complexity that had delayed Zone Zero since 2021 had not been resolved by the LA fires or by AB 1455. The fires had changed the political temperature, but they had also intensified the engagement of affected homeowners, many of whom were rebuilding or preparing to rebuild and were understandably resistant to new regulations that might constrain their options. The committee's work paused. A new target date was set for March 2026.

The April 2026 draft and where things stand

On April 17, 2026, the California Board of Forestry and Fire Protection released an updated draft of the proposed Zone Zero regulations, the most complete and current public statement of what Zone Zero compliance will look like when final regulations are adopted. The draft was released by the Zone Zero Regulations Subcommittee and reflected nearly a year of public workshops, site visits, and extensive public input conducted under the Zone Zero Advisory Committee process.

The April 2026 draft represented a significant evolution from earlier versions. It adopted a phased implementation approach that prioritized education and outreach over a five-year period, reflecting the political reality that strict enforcement from day one would not be achievable. It offered flexible approaches to live vegetation, allowing potted plants under specified height limits and trees with specified pruning requirements, that attempted to accommodate the concerns of urban homeowners while maintaining the core ember-resistant zone requirement. It confirmed that local jurisdictions would have some discretion in tailoring implementation while maintaining the uniform safety standard that AB 1455 had reinforced.

The draft also confirmed the immediate prohibition on new combustible fences within Zone Zero, one of the clearest and most enforceable provisions in the entire Zone Zero framework, taking effect upon adoption regardless of phase timeline. This provision, which applied to new fence installations even before the Phase 2 retrofit deadlines arrived, represented a meaningful immediate protection with lower implementation burden than whole-landscaping requirements.

As of June 2026, the April 2026 draft remains the most current published version. The Zone Zero Regulations Subcommittee is expected to forward its recommendation to the full Board of Forestry and Fire Protection, which will then consider and vote on final adoption. Once final regulations are adopted, the compliance clock starts: immediately for new construction, three years for Phase 1 existing-structure requirements, and local AHJ timelines for Phase 2. The five-year journey from AB 3074 to enforceable Zone Zero regulations is not yet complete, but the end is finally visible.
