Comcast Corp., continuing to grow, is out in the Center City office market looking for some extra space.

The cable company is seeking 65,000 to 75,000 square feet off additional space, according to people familiar with the matter. The company also wants the ability to expand if it needs to and that means just a few downtown office buildings can accommodate that arrangement. The short list of properties that could handle that assignment include 11 Penn Center, 10 Penn Center, Centre Square and Two Logan Square.

What’s more is it wants the space soon ­— beginning in October. Comcast would like to lease the space until the end of 2018 when its new Comcast Innovation & Technology Center is scheduled to be completed. The space need isn’t related to the proposed merger with Time Warner Cable but growth the company is experiencing, said people with knowledge of the situation.

This isn’t the first time Comcast has needed to lease some additional room since there’s no room left at Comcast Center. It occupies 200,000 square feet at Three Logan Square and 90,000 square feet at Centre Square.

The company has committed to approximately 1 million square feet at the new Comcast Innovation Center and has rights to grab an additional 300,000 square feet at the building until September of 2015.
