Ground-floor retail spaces that remain vacant for years are a common sight in many cities, even when the residential or office units above are fully occupied. Ann Ehrhart, founder of EVERSTREET in Boston, Massachusetts, says the root cause is usually more complex than developers assume. "Ninety-nine times out of one hundred, when retail is chronically vacant or challenged or turns over, something in that equation is sick," Ehrhart said. The equation she refers to includes merchandising, design, and underwriting, and when these three elements are out of sync with each other or with the location itself, vacancy follows.
Ehrhart's firm performs diagnostic work for projects where the retail plan is not working. The process reverses her usual five-step framework, essentially reverse-engineering what went wrong. Sometimes the tenant outreach targeted the right kind of retailer, but the space was never designed to accommodate them. Other times the space and tenant mix are both right, but the underwriting—rent structure and terms—is so far off that no tenant can make the numbers work. And sometimes all three elements are internally consistent but built for a Destination corridor when the property actually sits in an Untested one. "We always, in a diagnostic exercise, project assignment, take that formula, and we look at what the retail leasing strategy has been to date, and we diagnose which of those levers is problematic," Ehrhart said. "Sometimes it's one, sometimes it's multiple."
Once a storefront sits empty long enough, it can develop what Ehrhart calls a "vacancy stigma," making it even harder to lease. The good news is that this is not necessarily a sunk cost. "You absolutely can bring a space back from the brink of that stigma, but you can't do it without understanding what went wrong," she said. The risk is trying to fix the symptom instead of the cause. Ehrhart regularly hears from owners who have cycled through several leasing teams without changing outcomes. Swapping brokers while keeping the same underlying strategy tends to produce the same results.
For owners or developers facing dark storefronts, Ehrhart's advice starts with diagnosis, not action. Before bringing in a new leasing team or dropping rents further, the merchandising, design, and underwriting need to be evaluated together and measured against the specific corridor the property sits in. Rent reductions alone rarely solve the problem if the underlying mismatch is about tenant fit or corridor classification rather than price. Ehrhart's framework treats corridor type—Destination, Convenience, or Untested—as the fixed variable that everything else must align with, since location is the one thing a developer cannot change after the building is up.
Even seasoned developers tend to underestimate how expensive and irreversible retail decisions are, and how hard outcomes are to predict without a structured process. "Retail decisions are very expensive and irreversible, and outcomes feel almost impossible to predict," Ehrhart said. That is why she built a predictive modeling approach around market demand and location context, so these decisions can be evaluated up front instead of diagnosed years later. For developers and asset managers dealing with chronic ground-floor vacancy, the underlying message is that the fix is rarely as simple as a new broker or a lower rent. It requires figuring out exactly which piece of the equation—merchandising, design, or underwriting—is out of alignment with the corridor the property actually sits in.
