CEQA exemption guide: statutory and categorical exemptions and the Notice of Exemption

A project gets a CEQA exemption when a statute exempts it, it fits a categorical class no exception bars, or it can be seen with certainty it cannot have a significant effect[1]. The lead agency decides[2]; filing a Notice of Exemption (NOE) after approval cuts the time to sue from 180 days to 35[3][4].

Draft a Notice of Exemption for Infill Housing

    ePlan gets you

    • A first draft of your Notice of Exemption, 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 exemption memo and Notice of Exemption text from your project description, for your agency to review and file; every fact it can't confirm is marked for you.

    Statutory exemptions: what the Legislature exempted

    Statutory exemptions come from the Legislature and may cover all or part of CEQA[13]. Section 21080(b) lists these, among others[5]:

    • Ministerial projects; building permits and business licenses are presumed ministerial[14]
    • Emergency repairs, and actions to prevent or mitigate an emergency
    • Repairing or replacing facilities damaged in a disaster the Governor proclaimed
    • Projects an agency rejects or disapproves

    CEQA categorical exemption classes and the Class 32 infill exemption

    Categorical exemptions are classes of projects found to have no significant effect[6][7]. An agency may not require an EIR for them unless a §15300.2 exception applies[15]. On June 25, 2026, in Sunflower Alliance v. Department of Conservation, the California Supreme Court held that Class 1's "negligible or no expansion" refers to a facility's use, not to the risk of environmental harm[16].

    Class 32 covers infill of five acres or less within city limits that fits the general plan and zoning, is substantially surrounded by urban uses, has no listed-species habitat or significant traffic, noise, air or water effects, and has utilities and services[17]. Shares below are of the 11,546 categorical NOEs the State Clearinghouse received from October 2025 to September 2026; filing is optional, so not every exempt approval appears[18][8][9].

    Which exemptions agencies actually file, from CEQAnet. 21% cite more than one class, so shares overlap; Classes 5, 6 and 11 (2.6% to 3.7%) rank above Class 33.
    ExemptionWhat it coversNOEs citing itShare
    Class 1[19]Repair, maintenance or minor alteration of existing facilities with negligible expansion of use[16]6,94760.2%
    Class 3[20]Small structures: one home (three in urbanized areas), or a store up to 2,500 square feet2,01617.5%
    Class 4[21]Minor alterations to land, such as grading on slopes under 10 percent1,63714.2%
    Class 2[22]Same-site replacement with substantially the same purpose and capacity1,31911.4%

    Exceptions to categorical exemptions

    In 2010 the City of Berkeley exempted a 6,478-square-foot house with a 10-car garage on a steep lot under Classes 3 and 32. The Court of Appeal ordered an EIR, treating a possible significant effect as unusual in itself. On March 2, 2015 the California Supreme Court reversed in Berkeley Hillside Preservation v. City of Berkeley: the effect alone is not an unusual circumstance[25].

    If any of the six exceptions in Guidelines §15300.2 applies, the categorical exemption cannot be used; the last three are also in statute[26][6]:

    • Location (Classes 3, 4, 5, 6, 11): may affect a designated, mapped resource of critical concern
    • Cumulative impact: successive projects of the same type in the same place add up to a significant impact
    • Unusual circumstances: a reasonable possibility of a significant effect because of them
    • Scenic highways: may damage scenic resources on an official state scenic highway
    • Hazardous waste sites: a site on a Government Code §65962.5 list
    • Historical resources: may cause a substantial adverse change in a historical resource's significance

    AB 130 and SB 131: the 2025 exemptions

    AB 130 added §21080.66, exempting housing on urban sites up to 20 acres that meet conditions on prior use, zoning, density and historic structures; it requires an NOE[27][24][28]. SB 131 limits review of housing that misses an exemption by one condition to that condition[2], and added these exemptions, each with conditions[29]; counts are NOEs citing each from July 2025 to September 2026[18]:

    • Housing element rezonings (§21080.085): 30; farmworker housing (§21080.45): 1, under its old number[28]
    • Wildfire risk reduction near homes, such as prescribed fire and fuel breaks (§21080.49): 25
    • Since September 29, 2026, CAL FIRE's help with prescribed fire and cultural burning (AB 1699, §21080.49.1)[30]
    • Day care, health clinics, food banks and advanced manufacturing (§21080.69): 8
    • Bond-funded parks and trails (§21080.57): 11; high-speed rail facilities (§21080.70): 2
    • SB 954, which would have revised several of these, was vetoed September 18, 2026[31]
    Outline

    What a Notice of Exemption contains

    Required by Guidelines §15062[4]; filed notices appear on CEQAnet[32][33]. Projects that are not exempt usually start with an initial study.

    1. Project description

      A brief description of the project[4].

    2. Location

      Address and cross street, or a map, preferably a USGS quadrangle[4].

    3. Exemption claimed

      The exemption found, citing its Guidelines section or statute[4].

    4. Statement of reasons

      Brief reasons; for a categorical exemption, why no §15300.2 exception applies[26].

    5. Applicant and other parties

      The applicant and any recipient of public funding, a lease or permit[4].

    6. Filing

      After approval, by the lead agency, or by the applicant with the agency's certificate[8][9].
