No weep holes on the bottom course of brick.
Weep holes are absolutely needed in masonry veneer walls. Without them, any windblown water or condensate in the wall will remain there and be likely to cause water damage between the framed wall and the brick veneer. The weeps are only one part of a wall system, with rain screen, water barrier, and drainage paths. The weep is simply the last item in the path for water to egress.
