Chick-fil-A's real estate team accepts less than 1% of franchise applicants and is equally selective about locations. Costco requires average household income above $100,000 in the trade area before they will even consider opening. Trader Joe's site selection process takes years for a single store. These companies spend millions on demographic research before committing to a location. As someone who builds homes, I treat their work as free underwriting. Here are the 9 retailers and restaurants whose presence tells me an area can support a new residential development: 1. Chick-fil-A. Strong household income, high traffic, family oriented demographics. 2. Costco: minimum population density floor and $100k plus household income required in their trade area. That is the same demographic profile that supports single family new construction. 3. Trader Joe's: targets are educated, higher income households in areas with strong community identity. Seeing an opening is one of the strongest signals a neighborhood has arrived. 4. H-E-B (or your regional grocery anchor): In Texas, when H-E-B commits to a new location, they have already studied projected rooftop counts for the next decade. Outside Texas, the equivalent is Publix, Wegmans, or whatever dominant grocer controls market share. 5. Starbucks: uses a proprietary analytics tool called Atlas to map traffic patterns, demographics, and proximity to other retailers. A cluster of two or three locations within a few miles tells you daytime population and commuter traffic is significant. 6. Target: site selection leans on household income from $50,000 to $120,000, which is the sweet spot for attainable housing buyers. 7. Home Depot or Lowe's: an existing base of homebuyers investing in their properties signals pride of ownership in the community, which supports new construction and resale values. 8. Dutch Bros: expanding aggressively with remarkably good site selecting targeting high growth suburban corridors with younger demographics and strong car traffic. 9. Whataburger / In-N-Out / Wawa: these cult quick service restaurants do not expand recklessly. In-N-Out will not open more than a day's drive from a distribution center. When they show up in a new market, they've done an incredible amount of homework. When I drive a new market for first time, the retail and restaurant mix tells me more about the area than anything I could figure out sitting behind my computer.
