Continuing revitalization keeps Class B/C apartment demand high. Redevelopment projects underway throughout the metro are expanding the construction labor pool, which has grown by the fastest rate amongst job sectors in Atlanta over the past three years. Revitalization efforts are highlighted by the Centennial Yards project downtown, which will convert 50 acres of rail space into 12 million square feet of mixed-use development. A project of this scale will require a large volume of construction workers, many of which will seek housing aligned with their budget. With rental costs near the site out of reach, they will often look farther west for residences within the Perimeter. Here the average Class C unit rent is rising at an accelerated pace, and as the predominant beneficiary of this demand boost, tightening vacancy will continue to appreciate rent. Metrowide, employment gains in working-class fields are contracting Class B/C vacancy into the mid-4 percent area as median home costs are rising at a faster pace than the national level, prompting many to choose budget-friendly rentals.
