it depends on the length of the stringers, but for a basic one story
single run, yes you do need support under 2x12 stringers, or else you
need to beef up the framing. Without it, your stairs will have too
much bounce (at best). this shouldn't be a huge problem though--you
could cut the existing wall off at an angle following the stairs,
leaving the part that supports the stringers, or you could even tear
the whole wall out and rebuild a wall under the outer stringer.
