I have to say from experience...
If you move into a house (purchase/rent/otherwise) with a fig tree and plan to relandscape. Be very careful. Fig tree roots run very shallow, and even older trees are susceptible to damage to the roots.
I found out the hard way - rototilling an overgrown back yard due to too much grass, weeds, bulbs, etc. The 'till chomped through two or three large surface roots (< 8" deep which were more than 4 feet from the tree). The result - one dead 20+ y/o fig tree.
Be careful when gardening/redoing a yard.
