Could someone ID this yucca for me please?

Also, it is about four foot from the house; will the roots damage
the foundations/building?
Thanks.

I think your Yucca is Y. aloifolia. The roots shouldn't damage the
foundations of your house. If in doubt, cut any before they do reach
the building.

The floor is concrete, so I can't check the roots. Thanks for the
suggestion.
