Costco sets late-summer opening for new Lee’s Summit warehouse

Costco’s new Lee’s Summit warehouse is shaping up as more than another pin on the map. The club near the Missouri Route 291 and U.S. Route 50 interchange is set to open later this summer, and the staffing push has already started with job postings for any position, gas station attendant and tire installer. For workers across the Kansas City metro, that means a new store is about to pull in hiring, transfers and training work long before the first members roll through the doors.

The project sits inside a proposed 77-acre development that also includes hundreds of housing units, a scale that has fueled mixed reactions from neighbors as Lee’s Summit keeps wrestling with growth and land-use pressure. The application came from an Overland Park developer, and the warehouse plan has become one of the clearest signs that Costco’s 2026 expansion remains active in the region.

For Costco employees, the opening is really a workforce build-out. A new warehouse does not just need cashiers and stockers. It needs receivers, forklift operators, merchandisers, signage crews, sample setup, fuel-center staffing, tire service and managers who can set pace and safety standards from day one. The launch also typically pulls experienced employees from nearby warehouses to help train the new team, which can temporarily redistribute labor demand across the area while the new club gets up to speed.

That matters on the floor. Early opening weeks tend to expose where line flow, cart staging and replenishment systems need work, especially in a warehouse that has to learn its product mix fast, from Kirkland staples to seasonal items and food-court volume. It also matters for departments like meat, bakery and optical, where service routines and inventory discipline are harder to fake once traffic starts building.

Costco’s careers pages describe warehouse work as fast-paced and centered on merchandising, cleanliness, safety and member service. The company also says eligible employees receive a benefits package that includes paid time off, health coverage and retirement-related benefits. With Lee’s Summit already showing active job listings, the company appears to be staffing the location in stages rather than waiting for opening day.

The bigger picture is expansion with money behind it. Costco reported net sales of $69.15 billion for the third quarter of fiscal 2026 and $203.37 billion for the first 36 weeks of the year, a pace that matches its ongoing new-locations push. In Lee’s Summit, that growth is not just about a warehouse shell and a gas station canopy. It is about where Costco places jobs, how it trains them and which nearby stores feel the strain and opportunity that come with a new club.
