What is Proposition 45?
An Environmental Review Breakdown
Executive Summary: How Proposition 45 Changes Local Decision-Making
Proposition 45 rewrites state land use laws to remove planning power from local neighborhoods, city councils, and the legal system. Nearly every change benefits the developer. Nothing in the measure protects a community, preserves local environments, or gives residents a stronger voice in what gets built next door.
What’s at Stake for Our Communities:
- Default Approvals: Local governments are forbidden from pausing a project to wait for missing or delayed information. If planners miss the 30 day-deadline to check an application, it is automatically accepted as complete. And if environmental review deadlines are missed, the developer can force an immediate final vote, where officials must decide the project using whatever paperwork they have, even if key questions have not been answered.
- Curbing Community Input: Communities are given only one short window to review and respond to long, technical environmental reports that may determine what gets built next door. Once a draft EIR or MND is released, neighbors only have 45 days or 20 days to read complex studies, understand the impacts, and write meaningful comments. That is the only official chance to be heard, and local governments cannot extend it.
- Reduced Local Authority: Cities and counties lose the ability to make changes between the final environmental report and the permitting decision. That gap is where officials normally adjust projects to move buildings away from creeks, improve drainage, widen fire access roads, or require other safety and environmental fixes before approval.
- Disarming the Courts: Construction can no longer be automatically paused because a lawsuit is filed. Instead, work continues while the case moves through the courts unless the challenger can show a specific threat to public safety. Even if a judge finds that the environmental review was legally inadequate, the project’s approval remains in effect. The court can only halt the portion of the project that violated the law.

What Proposition 45 Does
Proposition 45 is a statewide ballot initiative that changes California’s environmental review and permitting laws. It rewrites parts of the California Environmental Quality Act (CEQA) and the Permit Streamlining Act (PSA), changing how certain development projects are reviewed and approved.
Proposition 45 sets mandatory deadlines for local agencies, changes opportunities for public participation, and revises how environmental decisions can be challenged in court.
A One-Sided Law
Proposition 45 changes state planning laws by replacing the usual step-by-step local permit process with a fast track. This new system is a one-way street. Using this fast track is completely optional for the developer. However, the law makes the fast track completely mandatory for local planners or the Lead Agency.
If a developer chooses to use Proposition 45 for a qualifying project, the local government cannot say no. The Lead Agency is forced to review the project on the developer’s terms. Local planning offices must meet tight, compressed review deadlines. They must also accept strict limits on their traditional oversight duty to protect the community by demanding safer, less damaging project choices. Most importantly, local planners lose their power to stop the clock to wait for missing data. The review clock keeps ticking unless the developer asks for an extension in writing.
Who Gets the Fast Track
The fast track applies to eight specific types of projects, no matter how big or small they are. It covers housing, water systems, and clean energy. It also covers schools, roads, high-speed internet, medical buildings, and public safety facilities.
A few specific projects are left out. The fast track cannot be used for Delta water tunnels, high-speed rail, or jails.
Because the law does not look at the size of a project, a massive regional power plant faces the exact same rushed deadlines as a small neighborhood housing development.
The Optional Pre-Application Review
Within the fast track option, a developer has a second choice that affects what versions of a project are studied during the environmental review. Scoping is the early phase where the public, agencies, and the developer can suggest what problems the project might cause and what different ways it could be built. The agency then decides what will actually be studied in the environmental report. If a developer wants to limit the review to exactly three versions of the project (their two proposed designs plus a no-build option), they must trigger a specialized track before filing their formal application.
If the developer skips this choice, the project still moves on the fast-track deadlines, but the planning agency retains its traditional power to demand a full environmental study looking at alternative locations or smaller project sizes.
If the developer chooses the streamlined track, the process follows a strict pre-application timeline:
- The 60-Calendar-Day Public Comment Window: The developer notifies the lead agency that they are using the streamlined track, and the agency posts that notice on its website. This starts a 60-day window for public input on what should be studied in the environmental review. It is the only early opportunity for public input in this process. Because notice is only posted online and not actively distributed, people may not know the process has started, even though the comment deadline is already running.
- The 15-Calendar-Day Developer Handover: After the 60-day window closes, the developer has 15 days to submit their proposed study scenarios to planning staff at the lead agency.
- The 15-Calendar-Day Agency Review: Planning staff then has 15 days to review and approve the developer’s submission. If it does not act within that time, the submission is automatically approved. An interested party can appeal the certification within 5 days; however, the measure does not say who hears the appeal or what happens if it succeeds.
Public Input in Court: Comments sent to the developer’s pre-application email address provide informal feedback only. Because they are submitted before a formal application exists, they are not included in the official administrative record. If a neighbor or community group wants their concerns to be considered in a future legal challenge, they must submit them again during the formal public review window later in the process.
How Time Is Measured
The measure uses two different ways of counting time. Environmental review deadlines run in business days, while all other deadlines, including public comment periods, hearings, and court timelines, run in calendar days. This creates overlapping schedules that are difficult to track and increases the risk that deadlines will be missed.
For smaller or rural planning departments with limited staff or contracted support, these fixed timelines can exceed available capacity and leave little flexibility to manage multiple projects at once. The same deadlines apply to all projects, regardless of size or complexity, meaning large developments are processed on the same schedule as smaller ones.
Because missing a deadline automatically moves the project to the next stage, low-resource agencies may be forced to make decisions with incomplete information or miss required deadlines altogether.
The Project Application
When a developer submits a proposal for an essential project, local planning staff must first determine whether the application is complete enough to be accepted for processing. Under this new law, they have exactly 30 calendar days to complete this initial check.
A written public checklist controls what they are allowed to require before an application can be accepted for processing. No new studies, reports, or additional documentation can be requested beyond what is included on the list.
If planning staff fails to issue a written decision before the 30 calendar day deadline, the application is automatically approved as “complete”. The project immediately moves forward into the formal processing phase, forcing planning staff to review the project using whatever paperwork they received, even if it is incomplete.
The Early Project Review
Once the application is accepted, local planners have 30 business days to decide how much environmental review the project requires. That decision determines the rest of the environmental review process.
There are three possible outcomes:
- Exemption: No new environmental study is required. This can happen because the project has already been evaluated in an earlier environmental report, or because state law exempts that type of project from further review.
- Mitigated Negative Declaration (MND): A shorter environmental review. It is used when potential environmental impacts are identified, but the planning department determines they can be reduced through required changes to the project.
- Environmental Impact Report (EIR): A full environmental study. It is required for projects that may cause significant environmental impacts and examines those impacts in detail before the project can be approved.
Review Deadlines
Each of these outcomes operates on its own deadline.
If the project is found exempt from environmental review, the agency has 90 business days to formally confirm that decision. The project then proceeds directly to permit decisions, skipping the environmental review.
If the project requires either an Environmental Impact Report (EIR) or a Mitigated Negative Declaration (MND), the deadline is measured from the date the application is deemed complete, not from the date planners assign the review type.
- The entire EIR process must be completed within 365 business days.
- The entire MND process must be completed within 180 business days.
By the time planners choose a review track, a month of that time is already gone.
Under current law, when a review process begins, state agencies are formally notified and given 30 days to identify what the environmental study should analyze. This input helps shape the scope of the report and becomes part of the official administrative record.
Proposition 45 leaves this step in limbo. If a developer does not use the streamlined scoping process, agencies are still supposed to receive notice, but nothing in the measure stops the review timeline while they prepare their responses. If the developer does use the streamlined process, the measure does not clearly say whether that notice is required at all. In either case, the measure does not identify agency scoping responses as comments that can be considered in court. To preserve those concerns for a legal challenge, agencies may need to submit them again during the formal public comment period.
Limits on Alternatives
An environmental study works by comparing scenarios to understand which option causes less harm. If the developer chose the optional pre-application scoping track before filing their paperwork, Proposition 45 lets the developer lock that comparison into exactly three required scenarios:
- the project exactly as submitted by the developer
- one alternative version of the same project, also designed by the developer
- no project at all, meaning what conditions look like if the project is not built at all
The no build scenario describes the reasonably foreseeable conditions if the project is not approved, including likely future uses of the site, and serves as the point of comparison for the build scenarios.
Under current law, environmental reviews must consider a range of alternatives, including different locations, which can move a project away from sensitive areas like wetlands, floodplains, or fire corridors. Proposition 45 removes that requirement if the three-scenario limit was triggered during the pre-application phase. The review is strictly limited to the developer’s two build scenarios plus the no-build option. Planners cannot consider moving the project, shrinking it, or redesigning it in any way the developer did not offer during that early pre-application window.
Automatic Approvals
The 365-, 180-, and 90-day deadlines all carry the same consequence if they are not met. If any deadline expires without a final decision, the process moves into two possible paths.
The developer can either agree in writing to extend the timeline, or they can issue a written demand for a hearing. Every deadline inside the review defaults in the developer’s favor.
If a written demand for a hearing is made, it triggers a new 60-day period. During that 60-day period, the local government must assemble all existing environmental documents, hold a hearing, and take a final vote to approve or deny the project based on the record as it stands.
The Preliminary Review phase ends when the draft environmental document (either the EIR or MND) is published and the comment period begins.
The Comment Window
Once the draft environmental study is published, the official comment window begins immediately: 45 days for an EIR and 20 days for an MND. This is the only chance for anyone to submit comments on the environmental review, including neighbors, community groups, and state reviewing agencies. The local government cannot extend the deadline. Only a court can add time, and the measure does not specify who may request that or why.
Because comments submitted during the optional pre-application phase do not carry forward into this window, they must be submitted again in writing during the comment period to become part of the official record.
What Counts in the Legal Record
This window also controls what a judge can consider if the project is challenged. A court can only rely on written comments submitted during the public input period.
There are two exceptions:
- Oral comments made at a properly noticed and recorded public hearing are included in the record
- A written comment may be submitted up to 48 hours before a hearing if the project significantly changed or new information surfaced
All other comments are excluded from the record.
State Agency Review
For State Reviewing Agencies, this is the only window to submit technical objections and proposed permit conditions into the project record. They must be filed in writing before the deadline to be preserved for the project record.
In practice, agencies do not respond as a single unified unit. Each agency assigns a CEQA coordinator who distributes the draft study to relevant technical staff. Those staff are typically organized by specialty, such as water quality, air emissions, biological resources, engineering standards, and other regulatory areas.
The specialty staff provide focused technical input tied to their area of responsibility. The coordinator then combines those findings, resolves conflicts between them, and produces a single formal submission of comments and conditions.
Each agency has a fixed, limited staff handling multiple projects at once, so every mandatory 45-day comment window competes with other required work, including permitting, compliance, enforcement, and deadlines across the agency’s programs.
The Final Vote
When the comment window closes, the lead agency must respond in writing to all comments received. These responses address the environmental issues raised and become part of the administrative record, along with the draft environmental impact report and the comments themselves. Responding to a comment does not require the agency to fix the issue it raises. The agency may instead explain why it disagrees and still certify the report without changing the project.
Once the Final EIR is complete, it goes to a governing body such as a Board of Supervisors or City Council. That body must certify the Final EIR and approve or deny all associated land use and zoning permits.
Loss of the Deliberation Window
Under current California law, environmental review and project approval are separate steps. First, the governing body determines whether the environmental analysis is adequate. Only after that does it vote on whether to approve, modify, or deny the project.
That separation creates a deliberation window where the board can:
- Add or refine mitigation measures
- Negotiate project design changes
- Request additional environmental analysis
- Return the project to staff for revisions
Proposition 45 removes that separation. Certification of the Final EIR and the final project decision occur in a single vote. The governing body reviews the completed study and votes yes or no on the project as a whole.
The board retains the power to deny the project, but it loses the intervening phase where conditions can be negotiated, studies extended, or revisions directed. Public testimony is included in the record but does not reopen review or trigger additional analysis, and with the review clock still running, the board has no room to pause, weigh new arguments, or send the document back to staff.
Going to Court
Legal challenges may only be filed after the governing body certifies the Final EIR and approves all project permits.
After the lead agency files the Notice of Determination, challengers have 30 calendar days to file a lawsuit contesting the adequacy of the Final EIR. The case is then placed on an expedited schedule requiring a final resolution, including any appeals, within 270 calendar days. The deadline can only be extended by a court order of up to 90 days, or if the challenger, the agency, and the developer all agree in writing.
The statute does not provide a separate deadline for when courts must begin review, but once filed, the case is governed by this mandated resolution timeline.
Construction and Court Limits
While litigation is pending, courts are blocked from pausing construction unless a challenger can show convincing proof of a specific threat to public safety and that people are in danger of being harmed. Even then, the court can only halt the single part of the project causing that threat.
Outside that narrow safety exception, activities such as grading, timber harvesting, and site preparation are allowed to continue during the lawsuit.
If the court later finds the EIR inadequate, the construction approval is not removed. The court may only block the specific noncomplying portion, phase, or activity of the project.
Any construction already completed will remain in place.
Limits on Court Orders and Evidence
All claims are limited to the closed administrative record. This means the court may only review information that was properly included in the record under the statute.
Information not submitted during the Draft EIR comment period, or not qualifying under the narrow exceptions, may not be introduced in court.
Because the law requires the environmental report to study fewer project alternatives, the court has less information to test whether the analysis was thorough and reasonable.
Each of these limits stacks on the last, so that once construction starts, there is very little a judge can do to stop it.
