What is CEQA? The California Environmental Quality Act, step by step

CEQA stands for the California Environmental Quality Act. It requires state and local agencies to avoid or mitigate, whenever feasible, the significant environmental effects of discretionary projects they carry out or approve[1][2][3][4]. The lead agency decides whether a project is exempt or needs a negative declaration, a mitigated negative declaration or an environmental impact report (EIR)[5].

    ePlan gets you

    • A first draft of your CEQA Document, from a project description or the files you already have
    • Precedent research: analog projects and their documents, found for you
    • Every fact ePlan can't confirm, marked for your team to fill in
    • A Word download, plus tasks and a Gantt timeline on Pro and Max
    See how it compares

    Describe the project and ePlan drafts the CEQA document it needs, from an initial study to EIR sections, following a reference document from a similar project; every fact it can't confirm is marked for you.

    ePlan vs. by hand

    How ePlan compares to drafting a CEQA Document by hand

    The same document, two ways to a first draft.

    What is CEQA, and who does it apply to?

    CEQA applies to projects: activities an agency carries out, funds or permits that may cause a direct, or reasonably foreseeable indirect, physical change in the environment[18]. That covers discretionary approvals such as zoning changes, conditional use permits and tentative subdivision maps, but not ministerial projects or emergency repairs[2]. Private development is covered only when it needs government approval, permits or funding[6].

    The CEQA process in three steps

    First, the lead agency checks whether a statutory or categorical exemption applies; if one does, review stops[19][20][6]. Second, it prepares an initial study[21]. Third, it prepares an EIR if substantial evidence shows the project may have a significant effect; otherwise it adopts a negative declaration, or a mitigated negative declaration when revisions the applicant agrees to clearly avoid the effects[2].

    Who is the CEQA lead agency?

    The lead agency has principal responsibility for carrying out or approving the project[22]: the agency running its own project or, for a private project, the one with the greatest responsibility for approving it as a whole, normally a city or county[23]. Its choice of document is final, including for responsible agencies, unless challenged in court[5].

    Responsible agencies hold other discretionary approvals over the project[24]; trustee agencies, such as the State Lands Commission, hold natural resources in trust for Californians[25]. The lead agency must independently review every negative declaration and EIR, including any a contractor prepares[26]. Before releasing either, it must begin consultation with any affiliated California Native American tribe that asked in writing to be notified and then requests it[27].

    Where are CEQA documents filed?

    Draft EIRs and proposed negative declarations go electronically to the State Clearinghouse, through CEQA Submit, and on the lead agency's website[26][8]. The Clearinghouse, part of LCI, circulates them to state agencies, and its CEQAnet database holds documents and notices received since 1980[11]. Class 1, existing facilities, appears in 60.2% of the categorical exemption notices it received from October 2025 to September 2026[28].

    A state agency files its notices with LCI rather than the county clerk[29][30]. Each public agency is responsible for its own CEQA compliance[31]. No agency enforces CEQA; lawsuits do[8], and they must be filed within 30 days of a notice of determination, 35 days of a notice of exemption, or 180 days if no notice was filed[32].

    Outline

    CEQA documents, in order

    The documents a CEQA review can produce, following the three steps[6]. Many projects stop at the first or second step. CEQA exemptions, the initial study and the EIR each have their own guide. When a federal agency also acts on the project, see CEQA and NEPA for joint documents. Other states have similar laws, including New York's SEQR and Washington's SEPA.

    1. Notice of exemption

      Optional, filed after approval: the project and its location, the exemption relied on and a brief statement of reasons[33].

    2. Initial study

      The project and setting, a checklist of effects with brief explanations, mitigation, consistency with zoning and plans, and the preparers[21].

    3. Negative declaration or mitigated negative declaration

      Circulated for public review of at least 20 days, or 30 through the State Clearinghouse, before the agency adopts it[34].

    4. Notice of preparation

      Tells LCI and the responsible, trustee and involved federal agencies an EIR is coming; responsible and trustee agencies have 30 days to comment on scope[35][30].

    5. Draft EIR

      Significant and unavoidable effects, mitigation measures, alternatives and growth-inducing impact[36], circulated for 30 to 60 days of public review[34].

    6. Final EIR

      The draft, the comments, a list of commenters and the lead agency's responses[37], certified before the project is approved[38].

    7. Findings and statement of overriding considerations

      A written finding for each significant effect[39][40] and, for effects that remain, the specific benefits that outweigh them[41].

    8. Mitigation monitoring or reporting program

      Adopted with the findings or a mitigated negative declaration so the measures are carried out[42].

    9. Notice of determination

      Filed within five working days of approval with the county clerk and the State Clearinghouse[7]; it starts the 30-day period to sue[32].
