Marin County is now part of Waymo's authorized territory for paid driverless rides, though residents shouldn't expect to hail a robotaxi on Tiburon's Main Street or in downtown Mill Valley anytime soon.

The California Public Utilities Commission approved Waymo's application on Friday, Aug. 14, clearing the Alphabet subsidiary to eventually offer fully autonomous passenger service across 18 California counties. Marin is among 12 Northern California counties on the list, which also includes San Francisco, where Waymo already operates.

The approval more than triples Waymo's authorized service area in the regions surrounding Los Angeles and San Francisco, according to the Los Angeles Times. But authorization is not the same as launch.

"While Waymo is receiving its permits today, expansion will be gradual and guided by its safety framework," spokesperson Sandy Karp told the Times. "Waymo's immediate focus is preparing to launch rider-only service in San Diego later this summer and continuing to validate its technology in Sacramento."

Waymo has not announced a timeline for Marin County service. The company's CPUC disposition letter covers operations on freeways, highways, city streets, rural roads, parking lots and rail crossings, day and night, in rain, fog and hail. The only exclusion is widespread snow or ice.

What this means locally

The CPUC approval covers areas within Marin County, but no public document specifies whether Mill Valley, Corte Madera, Larkspur or Tiburon fall within Waymo's operational boundaries. The California DMV separately authorizes where autonomous vehicles can physically operate, and Waymo's DMV-approved deployment map would determine which local roads are eligible.

Both agencies must sign off before a single robotaxi can pick up a paying passenger on any given street.

A long road from permit to pickup

Before Waymo launches in any new market, the company must map local roads, build charging infrastructure, establish a depot and set up remote-support operations. In existing markets, that process has moved through supervised driving, employee-only rides and limited public access before broader paid service begins.

Waymo's self-driving vehicles have logged more than 220 million fully autonomous miles, according to the company. As of May 2026, the fleet of roughly 3,000 vehicles had completed more than 20 million trips, Electrek reported. Waymo is targeting 1 million rides per week by the end of 2026.

The CPUC filing drew support from 29 organizations, including chambers of commerce, disability advocacy groups and Mothers Against Drunk Driving. Two San Diego transit organizations protested but were overruled.

What to watch for

Waymo has given no indication of when Marin County moves from authorized to active. Residents can monitor the DMV's autonomous vehicle deployment map for updates on which specific roads in Southern Marin are included in Waymo's approved zone.
