SACRAMENTO, Calif. — California voters have decisively rejected Proposition 45, a business-backed initiative that would have substantially changed the California Environmental Quality Act, handing environmental organizations and community advocates a major victory while leaving unresolved questions about how the state can accelerate housing and infrastructure construction.
According to election results reported by KQED and the Associated Press, approximately 56.2% of voters opposed the measure, compared with 43.7% supporting it, as additional ballots continued to be counted.
The Associated Press called the race Nov. 7, confirming the defeat of an initiative that had drawn tens of millions of dollars in campaign spending and divided environmental organizations, business groups, organized labor and housing advocates.
Proposition 45 would have imposed deadlines on environmental reviews, permitting decisions and litigation for a broad range of projects, including housing, transportation, water infrastructure, health care facilities, clean energy and broadband.
Under the measure, environmental impact reports for qualifying projects generally would have been completed within 365 business days, while lawsuits and appeals would have faced a 270-day deadline, subject to limited extensions.
Supporters argued that California’s existing environmental review process creates costly delays that prevent the construction of housing and infrastructure needed to address the state’s affordability crisis.
Opponents maintained that the initiative went far beyond streamlining approvals, weakening public participation and judicial oversight while potentially accelerating environmentally damaging development.
The No on Proposition 45 campaign celebrated the result as a rejection of efforts by corporate interests to weaken environmental protections.
“Californians have sent a clear message to corporate developers, utilities and data center builders that they will not stand for a broad assault at the ballot box on state law protecting our air, water and natural resources,” the campaign said in a statement.
“We were outspent but not outgunned, thanks to a broad bipartisan coalition that understood we can have progress and safeguard our environment at the same time.”
The campaign said it would continue defending CEQA in the Legislature while supporting efforts to make California more affordable.
According to campaign finance figures compiled by KQED from state disclosures, supporters raised approximately $42.5 million by late October, compared with $32.8 million raised by opponents.
Major supporters included the California Building Industry Association, the California Chamber of Commerce’s political action committee, Pacific Gas and Electric-related interests and Southern California Edison.
The opposition coalition included environmental justice organizations, public health advocates, organized labor and community groups.
Clean and Healthy California said approximately 600 organizations and elected officials joined the effort to defeat the measure.
The organization contributed more than $7 million to the campaign, while philanthropist Wendy Schmidt provided substantial additional financial support.
“California’s future cannot be dictated by corporate interests and fossil fuel companies,” Schmidt said in a statement following the election.
“Our work to stop toxic polluters from overturning California laws that protect communities is just one chapter in a much bigger effort.”
The outcome follows months of debate over whether Proposition 45 represented necessary regulatory reform or an overly broad weakening of environmental protections.
As the Vanguard reported Oct. 27, the state’s major newspapers reached sharply different conclusions about the initiative.
The Sacramento Bee endorsed Proposition 45, arguing that California needed enforceable deadlines and greater predictability to reduce construction costs and accelerate development.
The San Francisco Chronicle opposed the measure, acknowledging problems with CEQA but warning that the initiative would extend streamlined approvals to projects with potentially significant environmental consequences.
Both editorial boards recognized that environmental review procedures can delay needed housing and infrastructure.
Their disagreement centered on whether Proposition 45 offered an appropriate solution or imposed restrictions on public participation and environmental oversight that went too far.
The measure also exposed divisions within California’s pro-housing movement.
In earlier Vanguard coverage, several prominent housing organizations declined to support Proposition 45 despite longstanding advocacy for reducing regulatory barriers to construction.
Assemblymember Buffy Wicks, D-Oakland, and the Housing Action Coalition supported the initiative, arguing that additional changes were necessary to accelerate housing production.
California YIMBY and YIMBY Action declined to endorse the measure, while Greenbelt Alliance opposed it.
A central issue was whether recent legislation had already addressed many of the environmental review obstacles affecting urban infill housing.
Assembly Bill 130, enacted in 2025, established substantial CEQA exemptions for qualifying housing developments within existing urban areas.
Opponents argued that Proposition 45 would have extended expedited review procedures to projects on undeveloped land, including areas vulnerable to wildfires and environmentally sensitive locations.
Supporters countered that existing exemptions did not cover every needed housing or infrastructure project and that uncertainty over permitting and litigation continued to discourage construction.
Another major controversy concerned data centers.
Opponents warned that the initiative’s provisions governing broadband and related infrastructure could potentially accelerate approvals for large data centers, which can require substantial electricity and water resources.
Supporters disputed that interpretation, arguing that data centers themselves were not included among the projects eligible for streamlined review.
The disagreement became part of a broader debate over whether the measure’s language could produce consequences beyond those emphasized by its proponents.
The fiscal implications also became a campaign issue.
In a Nov. 2 Vanguard guest opinion, John Valencia, chairman of the Middle Class Taxpayers Association, argued that Proposition 45 would impose substantial costs on taxpayers while providing new advantages to developers and utilities.
Valencia cited an estimate from the nonpartisan Legislative Analyst’s Office that implementing the initiative could cost state and local governments $100 million or more annually.
He also argued that the measure contained no requirement for developers to reduce housing costs or utilities to lower consumer rates.
Supporters maintained that faster approvals could reduce project expenses and ultimately benefit consumers by allowing more housing and infrastructure to be built.
The election result preserves the existing framework of CEQA, including reforms already adopted by the Legislature.
It does not eliminate the underlying pressures that drove the campaign, particularly California’s housing shortage, infrastructure needs and the costs associated with lengthy project approvals.
For communities such as Davis, where housing proposals have generated extensive debate over agricultural land preservation, traffic, environmental impacts and development outside existing city boundaries, the defeat means future projects will continue to be evaluated under existing environmental review requirements.
Proposition 45 would not have eliminated local zoning authority or independently approved any particular development, but it would have changed the procedures and deadlines governing environmental review and litigation for qualifying projects.
Environmental advocates described the result as evidence that voters want development to proceed without weakening protections for affected communities.
The California Environmental Justice Alliance, whose member organizations participated in the opposition campaign, called the defeat a victory for communities seeking to maintain public participation in decisions affecting their neighborhoods.
The No on Proposition 45 campaign also emphasized that the election does not end the debate over CEQA.
“We know this fight is not over,” the campaign said. “We will continue to fight to maintain the integrity of the California Environmental Quality Act in the state legislature, and work to build a more affordable California.”
