Livermore, CA Noise Ordinances: Leaf Blower Rules (2026)

11 was added by AB 1346 (Statutes 2021, Chapter 753), effective January 1, 2022, and it works as a manufacturing and sale standard rather than a local use restriction, so Livermore's own code is silent on leaf blowers specifically. Subsection (a)(1) required the state board, consistent with federal law, to adopt cost-effective and technologically feasible regulations prohibiting engine exhaust and evaporative emissions from new small off-road engines "as defined by the state board," with those regulations applying to engines produced on or after January 1, 2024, or later if the state board determines that date is not yet feasible.

Subsection (a)(2) lists five factors the board had to weigh in judging feasibility: statewide emissions from small off-road engines, expected timelines for zero-emission equipment development, added electricity demand from more charging needs, the differing use cases of commercial versus residential lawn and garden users, and the expected availability of zero-emission generators and emergency response equipment, an express acknowledgment that backup generators and small engines share this same regulatory track. Subsection (b) separately directs the board to identify and, where feasible, make available funding for commercial rebates or similar incentive programs through district-level funding guidelines to support the transition to zero-emission small off-road equipment.

Because the mandate targets manufacturers and the state board's rulemaking rather than individual residents, Livermore police do not cite homeowners under this section; enforcement of the resulting equipment-certification standard runs through the California Air Resources Board's own regulatory and compliance program.
