I always thought, "leaves of three, let it be." This has 5. Is it still poison ivy?? If not, then what? It is vining at the foundation of the house.
Not PI, this is Parthenocissus quinquefolia, virginia creeper.
No it's called Virginia Creeper. It's safe to handle, Poison Ivy has three leaves.
Some people can be allergic to it. Personally, I've gotten breakouts from Virginia creeper worse than poison ivy. But that is rare.

The leaves of Poison Ivy are smoother than those of Virginia Creeper.
