I plan to plant a Sunset Maple and a Paper Birch on the side of the
house, what is the minimum, safe distance to avoid tree roots from
doing damage to the concrete house foundation ? Is 20 feet acceptable
? An are the roots for these two trees invasive ?

Hi Plant your trees close to the house the roots are not invasive.

Maples have a propensity to seek water; Sunset Maples are less of
a problem this way than some others, but I still wouldn't plant
them close to where water lines enter or leave the house. Whilst
these are not terribly invasive, the roots of any tree will cause
damage to a foundation if planted too closely, and the foundation
will tend to stunt the tree. So, you should plant the trees at
least one-half the mature diameter of the crown away from the
house. This also has the advantage that the branches will not
eventually have to be trimmed so that they do not damage the
house. The final consideration in placing trees is what will
happen when the tree inevitably dies and falls over. If this
happens suddenly in the middle of a windstorm, one can find
oneself possessed of an instant new entrance into one's dwelling,
or lacking a porch or roof. Therefore, one should plant a tree
far enough away from the house that, when it blows over as a
mature tree, the main trunk doesn't land on the house. With
maples and birches, that's about half the height of the mature
tree.
