Adding a dba to my LLC. Do I need another business license?

I have my main company set up as an LLC, but I want to set up a dba for a new branch of the company that does encompes different jobs. I have a local business license for the LLC, do I need to get another business license for the dba also, or will it fall under the operation of the LLC? I can't imagine I do, but I want to me sure.
