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. 

"Our office clients choose downtown for its beauty, the amenities, the walkability of the city, and the synergies with other businesses in the area," Bill Sparks, a first vice president with CBRE, tells GlobeSt.com. "In a competitive labor market locating is a desired area can help with recruitment and retention,"

All this means Millennials hoping to pursue or continue in professional business in Savannah will benefit from a healthier and more active office environment. Since 2010, Savannah's population has seen the percentage of Millennials jump from 23% to 26%.

At that rate, CBRE reports, Millennials by 2020 could account for one-third of Savannah's population. As the number of jobs in the professional and business service sector increases along with the labor force, Savannah's office market could begin to heat up.
