ATLANTA—Savannah is seeing a shift in employment—and that's positively impact the office market. The Georgia city is posting professional and business services that are driving new employment growth at 12.3% year-over year.

That's according to CBRE's latest research. The overall office vacancy rate, meanwhile, decreased to 6.4% in the third quarter of 2015.

Of course, with the tighter market comes steeper office rents. To be sure, it's a good time for landlords and owners as rents for the office space in the revitalized heart of Savannah along Broughton Street are 25% higher than the average rent for downtown Savannah. The downtown submarket has seen the most activity recently, with companies opting to locate in Savannah Historic District.
