ATLANTA—If you are looking for office space in Atlanta, which is one of the hottest tech markets in the nation, you should not only expect to pay a premium—you should expect to pay a heavy premium. So says a new CBRE research report.

The report analyzes the top 30 tech cities across the U.S. and Canada—and showed an aggregate rent premium of 11% across all 30 markets. That number jumps significantly higher in the hottest tech submarkets, including Santa Monica, which had the second-highest rent premium in North America, between Boston's East Cambridge at 87% and Mountain View (Silicon Valley) at 73%.

In Atlanta, the technology job growth rate has risen 7.8% between 2012 and 2014, above the 5.7% national rate and 22nd among the top 30. Atlanta also offers lower than average office rents, ranking 23rd nationally for office rent growth. Atlanta stands out as a potential destination for tech employers because of its affordability, CBRE says, and is also considered an emerging market with potential for continued growth.
