The Starbucks at 1663 N. California Blvd. in downtown Walnut Creek will close permanently after Saturday, Sept. 26, a staff member told Bay Area Telegraph.

The closure marks the second downtown Walnut Creek Starbucks to close in roughly a year. The location at Mt. Diablo Boulevard and Locust Street shut down in September 2025. Customers looking for another downtown Starbucks can find one at 1340 N. Main St.

The N. California Blvd. coffeehouse opened Feb. 24, 2014, on the ground floor of the Mercer apartment building, at the corner of California Boulevard and Cole Avenue. It operated for more than 12 years.

The Sept. 26 closing is part of a larger wave. Starbucks Chief Operating Officer Mike Grams said in a Sept. 24 message to employees that the company would close about 250 coffeehouses across North America during the week of Sept. 22, roughly 1% of its more than 18,000 locations in the region.

Grams said the company identified stores where it could not consistently deliver the experience it wants for customers and employees, or where it saw no path to acceptable financial performance. Starbucks has not said publicly which of those factors applies to the Walnut Creek location.

The 250-store round is the second major closure wave under CEO Brian Niccol, who joined Starbucks in 2024, the Associated Press reported. Last September, the company closed 627 stores in North America and Europe.

In a securities filing dated Sept. 22, Starbucks estimated the latest closures would bring about $300 million in restructuring charges. That includes roughly $200 million in cash costs tied to lease exits and employee separation, plus $100 million in non-cash charges.

Starbucks said it would offer transfers where possible to employees at closing stores and severance support to those it cannot place elsewhere.

The closures come alongside renovations. Under its "Back to Starbucks" plan, the company said it has redesigned more than 1,000 U.S. and Canadian coffeehouses since late 2025 and aims to reach at least 1,500 by Sept. 30, the end of its fiscal year.

Starbucks has not said what will happen to the ground-floor retail space at the Mercer building after the coffeehouse closes.
