The last-mile problem has largely been solved for consumers. Within a day, UPS or Amazon can put a package on anyone’s doorstep. But sometimes instead of the doorstep, that package ends up in the bushes, or lost among a sea of boxes in a building’s leasing office. The last mile is no longer the issue. The problem now is the last 50 feet. Multifamily and apartment buildings have been attempting to solve the disconnect between delivery and tenants by implementing digital storage lockers, which tenants can unlock with a code to retrieve their items. But in apartments, space is limited, and lockers are costly. With e-commerce growing 20% year over year, lockers are starting to look like a short-term solution to a long-term problem.
