What is it?

Prop 45 adds a new set of rules to the California Environmental Quality Act (CEQA), the state law that requires agencies to study a project's environmental effects before approving it. The rules set deadlines and limit lawsuits for eight categories of projects.

The eight categories, which Prop 45 calls "essential projects," are housing, clean energy, water, public health, public safety, broadband, education facilities, and transportation. Using the new rules is up to whoever proposes the project, whether a company, a public agency, or a utility. They can choose the faster process, stick with regular CEQA review, or mix the two. Either way the project still goes through environmental review, and the agency in charge can still approve or reject it.

The housing category covers any housing, including market-rate. There is no affordability requirement anywhere in the definition.

Deadlines

The longest clock is 365 days for an environmental impact report, then 180 days for a negative declaration, 90 days for an exemption, and 30 days to decide whether an application is complete. The main review clocks run in business days, not calendar days, so the 365-day EIR clock works out to roughly 1.4 calendar years, longer than CEQA's existing one-calendar-year deadline.

Only the applicant can extend a review deadline. If an agency misses a deadline, the applicant can demand a hearing where the agency must vote the project up or down using whatever environmental documents exist, and the applicant can sue to force it.

Lawsuits

Prop 45 also narrows what courts can do: a challenger's claims are limited to "objective existing laws," and a court that finds a violation may block only the part of the project affected by it until it is fixed, but may not order the agency to rescind its approval.

Why vote Yes?

Environmental review in California has no clock, and finishing it buys no certainty. An agency can take years to review a housing project or a solar farm, and once it's finally approved a single lawsuit can void it and send everyone back to the start. The only guaranteed winner is whoever wanted nothing built.

Prop 45 puts the process on deadlines for essential projects: housing, water, clean energy, clinics, schools, broadband, and transit. Agencies get 30 days to deem an application complete, 90 business days to rule on an exemption, and 365 business days to finish an environmental report, and an applicant can force a decision when an agency blows a deadline. Lawsuits must finish, appeals included, within 270 days, and a court can halt the piece of a project that breaks the law but can no longer kill the whole thing.

Nothing is exempted; every project still completes environmental review under the same laws. The Sierra Club objects that narrowing what opponents can sue over weakens enforcement, and that is the real trade: Prop 45 moves power from whoever can afford a lawsuit to whoever follows the written rules. We think that is the right trade, applicants can choose whether to use the faster process, and the Legislature can amend it by a two-thirds vote, which most initiatives never allow. The costs land where they should, too: the Legislative Analyst's Office expects start-up costs for private projects to be covered by applicant fees and reimbursements, and likely long-term net savings for government from the reduced workload.

The Legislature proved the logic in 2025 when it exempted most infill housing from CEQA. Prop 45 extends the same logic to the rest of what California is short of. Delay is a policy choice, and you pay for it in rent, energy bills, and water rates. Vote yes.
