The long-stalled Costco store in Brentwood opened on Friday, the chain’s largest in Contra Costa County.
After a 7:30 a.m. ribbon-cutting, the 155,000-square-foot warehouse store opened its doors to shoppers. Some had been waiting since the night before, with more than one telling a TV reporter they were there to snap up bottles of high-end bourbon.
The store is at Heidorn Ranch Road and Lone Tree Plaza Drive, adjacent to Highway 4, with neighbors including Home Depot and Trader Joe’s. It has a 32-pump gas station; on Friday, the company’s website listed a price of $4.39 a gallon.
Brentwood’s Planning Commission approved the project in 2023, but it was delayed by a lawsuit by Albert D. Seeno III’s West Coast Builders that challenged it on environmental grounds. The suit was withdrawn in June 2024, allowing construction to go forward.
The store is one of six U.S. openings planned by Costco in the next two weeks; on Saturday, March 8, a store will open in Highland, in San Bernardino County.
The Brentwood store’s hours will be 10 a.m. to 8:30 p.m. weekdays, 9:30 a.m. to 6 p.m. Saturdays and 10 a.m. to 6 p.m. Sundays. The gas station opens at 6 a.m.
