The integration of large-scale retail and residential development is becoming one of the most exciting trends in commercial urban planning in the United States. Costco's announced project in Los Angeles, which involves the construction of a warehouse nestled within an affordable housing complex, is a prime example of this evolution.
In the Baldwin Village neighborhood, the retailer plans to develop a store within a building that will house approximately 800 apartments, a significant portion of which will be for low-income residents. The project will combine commercial and social functions, positioning the store as a local infrastructure for hundreds of families.
The model isn't entirely new. In the Washington, D.C., metropolitan area, several mixed-use projects have already integrated food retail and residential spaces in Tysons, Virginia. In 2019, Whole Foods Market opened its Mid-Atlantic flagship store in a building with apartments on the upper floors, cementing the idea of the supermarket as an anchor tenant in high-density neighborhoods.
The logic is clear: reduce the need for car travel and promote walkable communities where people can live, work, and shop on the same block. For cities attracting large companies and new residents, this approach optimizes space and minimizes the impact on urban traffic.
In Costco's case, real estate leverage is equally strategic. A traditional warehouse typically requires between 14 and 16 acres of space, while the Los Angeles project will only require five. In urban contexts where land is scarce and expensive, verticalization and shared space represent a concrete solution.
This phenomenon is part of a broader trend. Between 2012 and 2021, the number of "live-work-play" projects completed annually in the United States quadrupled, according to real estate market analyses. These are developments that combine residential, restaurant, office, and retail in a single integrated platform.
For food retailers, these settings offer tangible benefits. Foot traffic in mixed-use complexes can be 20-30% higher than in traditional retail locations, generating higher footfall and natural resident loyalty.
At the same time, new complexities are emerging. The presence of multiple stakeholders—developers, investors, local governments, and commercial operators—requires careful coordination, especially regarding logistical aspects such as access, parking, and heavy vehicle movement.
Occupancy costs can also be higher: rents in mixed-use developments tend to be 10-20% higher than those in traditional shopping centers. However, the guarantee of a stable customer base, consisting of the building's own residents, partially offsets the increase in rents.
The placement of supermarkets on the ground floors of residential buildings is no longer an exception but a structural trend in high-density neighborhoods. The evolution of the urban format suggests that large-scale retail trade, especially in large metropolitan centers, will continue to integrate with housing to maximize real estate efficiency and proximity to consumers.
