Costco announced plans to open 33 new warehouse locations during fiscal year 2027, with five of those sites serving as relocations. The expansion targets growth across the United States, Europe, Canada, and Mexico as the company maintains its long-term strategy.
Why it matters
The consistent pace of physical expansion underscores the company's aggressive growth strategy and its commitment to scaling warehouse operations despite changing global market conditions. Operators should monitor how this footprint growth impacts local labor demand and supply chain requirements in these expansion regions.
Costco plans 33 new warehouses for fiscal 2027, including 14 openings scheduled for October and November 2026. This expansion features 10 international sites across Europe, Canada, and Mexico, alongside planned locations in Southborough, Massachusetts, and counties in South Carolina and Florida.
The players
Costco
A multinational warehouse club operator that drives revenue through a subscription-based model and high-volume, low-margin inventory management.
Atlantic Management Corp.
A real estate development and management firm that specializes in commercial property acquisitions and site preparation for large-scale retail projects.
The details
The expansion strategy relies on securing new sites through local zoning changes and land deeds, as seen in Southborough where town meeting members approved a zoning change in October 2025. Atlantic Management Corp. subsequently signed a deed for the site in January 2026, illustrating the company's dependency on municipal cooperation. The strategy combines new builds with periodic relocations to optimize store performance and capacity.
Timeline
October 2025: Southborough members approved a necessary zoning change.
January 2026: Atlantic Management Corp. signed a deed for the site.
Summer 2026: Costco submitted plans for South Carolina and Florida sites.
October-November 2026: Costco will open 14 stores.
Summer 2027: Southborough warehouse is expected to open.
Market Landscape
Costco is continuing its long-term growth pattern by exceeding its established target of 30 net new warehouse openings annually. This trajectory confirms a sustained commitment to physical store expansion even as competitors increasingly pivot toward e-commerce and smaller-format fulfillment centers.
Operators in proximity to planned sites should prepare for localized impacts on labor markets and increased traffic volumes surrounding major retail developments. Tracking these zoning filings provides a lead indicator for where regional commercial infrastructure investment is being directed.
The takeaway
Large-scale expansion into new markets requires years of lead time in zoning approvals and real estate acquisition. Owners should monitor local planning board agendas in their own regions to identify which major retailers are securing land for long-term development.
