Three New Costco Locations

Not All Costco Openings Are Created Equal

Two new locations in Brentwood and Highland, California are already outperforming the national average. Within three months of opening, both stores surpassed $20 million in monthly sales, putting them comfortably in the top quartile for California. By month four, Brentwood’s Heidorn Ranch Road location hit nearly $30 million, doubling the average store run-rate Costco has seen across its post-2023 openings.

But not every new box is scaling at that pace. The 6200 Lafontaine Way location in Flint, Michigan peaked just above $12 million monthly, then declined over its first eight months. The store is now tracking below Costco’s national average for new openings, sitting in the bottom 10% statewide.

Costco’s footprint is famously productive, but these early curves underscore a real estate truth: even at the highest-volume banners, site matters. Demographics, access, regional saturation—each can tilt the curve. And in a year where comps are tightening, Costco's new-unit performance is as much about precision as scale.
