Florida’s long-awaited Treasure Coast Costco officially opened on April 25, 2025, marking a major addition to Stuart’s growing retail corridor. The 162,000-square-foot warehouse off Kanner Highway includes an 18-pump gas station and anchors a 49-acre mixed-use site that will later feature apartments and restaurant space. Its opening followed years of delays tied to environmental and traffic disputes.
Construction and Opening
After a state panel reversed an earlier rejection in 2023, construction moved quickly and wrapped by early 2025. When doors opened in April, the store drew heavy crowds and thousands of new memberships. The Stuart warehouse joined a wave of new Florida openings that have extended Costco’s reach across the state, from Naples to Jacksonville.
Customer Experience So Far
Initial lines and traffic jams have eased, and reviews remain mostly positive. Shoppers praise the store’s organization, helpful staff, and cleanliness. One reviewer said, “You could eat off the floor,” while another called it “the cleanest Costco I’ve seen.” A few complaints cite slow tire service and opening-week congestion, but most feedback describes a strong addition to the area’s retail options.
Location and Community Impact
Located near Martin County High School, the Stuart Costco serves a region that previously lacked a nearby warehouse club. The broader project still has uncompleted portions, including planned restaurants and about 378 apartments. Even so, the store’s success underscores growing demand along the Treasure Coast and positions Stuart as a key hub in Costco’s Florida expansion.ing for one of Stuart’s biggest retail additions.
