brick instead of the normal weep hole spacing. My theory is that the builder planned that the many weep holes would provide ventilation up between the brick veneer and the sheathing to the attic. The attic did have baffles to keep the blown insulation away from the edges of the attic.
The house was a zero lot line variety where one side sat on the lot line and was about 1900 sq ft.
And to make matters more interesting, the bathroom and laundry room exhaust fan vent lines disappear into the insulation near the eves and there was no visible termination for those to be found anywhere. Possibly venting moist air down between the wall and the brick???

Doing a few back of the napkin calculations (yes I know that HI are not engineeres but I can't help myself) leads me to believe that about 1000 weep holes would be needed to provide the necessary ventilation area and there weren't over 200 weep holes around that house.
Anyone seen this before? Comments?
p.s. based on the houses on either side, it seems to be the standard practice for this builder in this development.
