Answer: Unlike the invasive/aggressive roots of many other trees, ficus roots are not generally considered a threat to sidewalks, driveways or foundations. As a matter of fact the trees are often recommended for entryway and patio plantings. Expect a full grown ficus to reach 30' in height. You can keep it smaller with annual pruning, and can even trim it into a hedge, rather than allow it to grow into a 30' tree.
