Absolutely not acceptable.

All siding leaks.

See here for correct method of installing housewrap.

And, at least on my screen, I don't see the plastic cap nails or staples that should be used to affix the wrap to the house

I'm betting they went back 20 years and used a hammer stapler, as above.

On the plus side (for the builder) he will be long gone before you start noticing moisture damage on the interior your home.

It looks like the wrap in the gable was folded up at the bottom. The gables might have been done before the wall below.

After the wall below was wrapped, they should have pulled the flap down to cover the gap.

The trim needs to come off, the wrap fixed, then trim reinstalled.

Another project where the owner is struggling to provide quality control.

Another built-in problem with another production-built home.

I agree with PPF; the house wrap was folded up. It was folded up in both the smaller and larger gable, presumable anticipating some sort of cornice return would be added. The house wrap would have then been folded down over the flashing at the intersection. If you look at the larger gable, which has already been sided, it's difficult to know if it was flashed at all.

Thank you for the helpful comments to let me know this is something that definitely needs to be addressed!! PM sent us an update. We are very thankful that this was caught and addressed.

I'd still be concerned about the upturned house wrap at the intersection of the larger gable and the cornice return. If it isn't flashed properly with the house wrap over the flashing or if they left the house wrap upturned, you could have problems.

It is common to run the WRB long in panelized construction, so when you set the upper panelized wall the most critical thing is to overlap the upper WRB over the lower (just like roof shingles and water). Unfortunately, what Charles Ross Homes is saying at the larger gable they already installed the siding and eyebrow roof and surely didn't fix the WRB. Also, presumably along the "blank" sides and back walls the 2nd floor was left folded up as well and just installed siding over.

The overlap needs to be 2" minimum, or any moisture collected behind the siding will just run down onto the exposed sheathing and behind the lower sheet of WRB. Also, the WRB must overlap the future flashing that needs to be put on the roof, which is hard to do when the siding and trim is up and they haven't left enough of a gap between the siding and roof.
