Jason Rodriguez, 40, surrendered to police about three hours later, after officers saw him through the window of his mother's home and asked him to come outside, Orlando Police Chief Val Demings said.
She said investigators did not know why Rodriguez targeted the engineering firm where he once worked.
"This is a tragedy no doubt about it, especially on the heels of the tragedy in Fort Hood that is on our minds," she said. "I'm just glad we don't have any more fatalities or any more injuries than we currently have."
People streamed out of the 16-story Legion Place office building around lunchtime and some told local television stations they had barricaded themselves inside their offices while the gunman was on the loose.
Mike Bernof, a spokesman for Reynolds Smith & Hill, the transportation engineering consulting firm where Rodriguez was an engineer, told CNN Rodriguez was released in June 2007 for performance issues. He could not say what those issues were. The firm performs transportation engineering work for the Florida Department of Transportation.
Gerry Gilgo, who works on the floor where the shooting occurred, told The Associated Press she was meeting a co-worker at the elevators for lunch.
"She yelled, 'There are gunshots! There are gunshots! Get back in your office,'" Gilgo said.
Will Halpern, an attorney on the building's 17th floor, was among the last group to be evacuated. He said the lobby was filled with about 20 officers in SWAT gear, carrying assault weapons, ready to search.
Interstate 4 was closed in both directions through downtown and nearby schools were locked down until the gunman was caught.
Rows of ambulances lined up outside the building as police snipers took up positions around the building and officers on foot and horseback searched the area.

Bad news, that suspect is totally a freak. The Ft. Hood massacre and the Orlando shooting both occurred within 24 hours of each other – Nidal Malik Hasan and Jason Rodiguez (both allegedly) went on their deadly sprees in such close proximity. Of course, neither had anything to do with the other, but that's pretty creepy when you think about it. Thankfully, both are in custody – Rodriguez was peacefully arrested hours after he killed one and wounded five, and Hasan is in the hospital after being shot four times. The officer, Kimberly Munley, deserves high praise for her bravery despite being wounded, and doubtless saved more lives. The President attended services for the Ft. Hood massacre victims – I'd give money now to have them both strung up.
StoshDosh, I've never seen a gun kill someone by itself. It needs a someone to pull the trigger. What are you proposing, we ban guns?
