AB 439 California Assembly · 2025-2026 Regular Session

California Coastal Act of 1976: local planning and reporting.

Summary
Existing law, the California Coastal Act of 1976 (the Coastal Act) , among other things, requires anyone wishing to perform or undertake any development in the coastal zone, except as specified, in addition to obtaining any other permit required by law from any local government or from any state, regional, or local agency, to obtain a coastal development permit, as provided. The Coastal Act generally requires each local government, as specified, to prepare a local coastal program, for certification by the California Coastal Commission. Existing law also imposes an analogous requirement on port governing bodies to prepare port master plans, for certification by the commission. With regard to local coastal programs and port master plans, existing law provides that an amendment determined to be de minimis by the executive director of the commission, after notice in the agenda of the next scheduled commission meeting, becomes a part of the certified program or plan 10 days after the commission meeting if 3 or more members of the commission do not object to the de minimis determination. This bill would make de minimis amendments to local coastal programs and port master plans effective upon adjournment of that meeting if 3 or more members of the commission do not object to the de minimis determination. The Coastal Act authorizes the commission to impose specified administrative penalties on a person, including a landowner, who is in violation of any provision of the act other than public access, and separate administrative penalties for violations relating to public access. Regarding the violations of the act unrelated to public access, existing law requires the commission staff to annually prepare and present a written report to the full commission that includes specified information related to the imposition of those penalties and to annually provide the written report to the Legislature, as prescribed. This bill would require the commission staff to prepare and present a written report to the full commission every 5 years instead of annually, as specified, and would require the report to address public access violations as well. The bill would require the report to include, in addition, the number of violations referred to the Attorney General, the number of pending violations at the end of the reporting period, and summaries of violations that were resolved that are both illustrative of the commission's enforcement workload and that provided significant public benefit. This bill would repeal an obsolete reporting requirement that concerned violations of the act related to public access.

MODERATE
AB 439 was amended between introduction and enrollment to speed up the effective date of de minimis coastal plan amendments (removing a 10-day waiting period), reduce the frequency of enforcement reporting from annual to every five years, expand that report to cover both public access and non-public-access violations, and repeal an obsolete one-time reporting requirement. These changes streamline the California Coastal Commission's administrative processes while maintaining oversight through less frequent but more comprehensive reporting.
TIMELINE

De minimis amendments to local coastal programs (Section 30514) and port master plans (Section 30716) now take effect immediately upon adjournment of the commission meeting, instead of 10 days after adjournment. This shortens the time for minor, no-impact amendments to become part of certified plans.

REQUIREMENT

The enforcement report required under Section 30821.3(i) is now due every five years instead of annually. The first report is still due at the first public hearing after January 1, 2024, but subsequent reports are only required every five years.

Removed the reporting metric tracking 'the number of days from initial notice to resolution of violations for those resolved in the previous year' (former item 4 in Section 30821.3(i)).

Repealed an obsolete one-time reporting requirement in Section 30821(i) that had required a report by January 15, 2019 covering violations from 2015 to 2018. This deadline has long passed and the requirement is no longer operative.

SCOPE

The enforcement report under Section 30821.3(i) now covers both Section 30821 (public access violations) and Section 30821.3 (other violations), rather than only Section 30821.3. All data in the report now covers a five-year lookback period instead of the previous year.

ENFORCEMENT

The method of delivering the enforcement report to the Legislature changed from annual delivery to specific policy and budget committees in both houses to delivery pursuant to Section 9795 of the Government Code (the standard legislative reporting process).
