Summary
Berkeley's only vehicle-idling limit sits inside its diagonal-parking rule: Municipal Code Section 14.40.060(B) caps engine idling at sixty seconds on any street where back-in diagonal parking is marked by a traffic control device. The city has no broader anti-idling ordinance covering general street parking, loading zones or drop-offs.
B. Upon any portion of a street where back-in diagonal parking is indicated by a traffic control device, no vehicle shall idle more than sixty seconds. C. No vehicle shall be parked in a diagonal parking zone if it exceeds twenty feet in length or eight feet in width, including cargo or load.
Official source re-checked September 8, 2026: no newer edition of the code had been published (publisher’s edition: current through Ordinance 8031-NS, passed July 28, 2026).
Full Breakdown
060 governs diagonal parking on streets the City Council has designated by resolution. Subsection A sets the parking geometry: vehicles must sit at the angle shown by signs or pavement markings, bumper within 12 inches of the curb, or within 12 inches of the bike lane's dividing line where a bike lane runs between the diagonal spaces and the curb. Subsection B then adds the idling cap: on any portion of a street where a traffic control device indicates back-in diagonal parking specifically, a vehicle may not idle for more than sixty seconds, limiting the time a driver spends maneuvering into the reversed space with the engine running.
Subsection C limits vehicle size in those same zones to twenty feet in length and eight feet in width, including any cargo or load. None of these provisions apply outside a diagonal parking zone; the code has no equivalent citywide idling limit for cars waiting at a curb, queued at a school pickup line, or stopped at a loading dock. 050, which the diagonal-parking section cross-references for that exception.
Violations & Fines
Exceeding the sixty-second idling limit in a back-in diagonal parking zone is enforced as a parking infraction under Section 14.64.010, carrying the standard Chapter 1.20 fine schedule of up to $100 for a first offense, $200 for a second, and $500 for each additional violation of the same section within a year. Because Section 14.40.060 sits within Title 14's general parking-penalty framework, a citation for excess idling is treated the same as any other diagonal-parking violation rather than as a separate environmental offense.
