Costco officially opened its new Lee’s Summit, Missouri, warehouse on Friday, October 2, 2026.

Costco Has Even More New Stores Coming

Costco’s November 2026 openings include:

• South Meridian, Idaho — Opened November 5
• Vallejo, California — Scheduled to open November 6
• Chandler Business Center, Arizona — Scheduled to open November 7
• Franklin, Wisconsin — Scheduled to open later in November

Costco’s website lists November 25 for Franklin, while the Milwaukee Journal Sentinel reports that the mayor announced an earlier opening of November 24 at 8 a.m. Check with the warehouse before planning an opening day visit.

The Vallejo warehouse at 860 Admiral Callaghan Lane will replace the existing Plaza Drive location. Chandler’s new location is a Costco Business Center, which carries a different merchandise selection focused on business needs and is open to all Costco members.

Costco also lists an upcoming gas station at 12490 Jefferson Avenue in Newport News, Virginia. Its official page currently says “Gas Station Only,” so it should not be counted as a confirmed November warehouse opening.

Opening schedules can change. Check Costco’s individual location pages before planning a trip.
