No sheathing behind siding on gable
Im looking at a buying a renovated 1930s home. I peaked in the attic and could see the light from outside the house through the siding on the gables. There was no kind of vapor barrier, house wrap, plywood, or anything. Only the new wood siding nailed on the 2x4s on the outside of the house. i could see light from most of the cracks in the siding. Would this be an issue? it seems like water and moisture would come in the cracks and cause problems like dry rot...

Lets see, the house was built in the 1930's, was there any rot you could see?
Not the best way to have done it but 1000's of homes have gable end vents with nothing but screens to stop water from getting in and are fine.
A house that old I'd be more concered with the wiring. plumbing, old windows and lack of insulation.

All wiring, plumbing, drywall insullation, flooring,siding, were changed out. a new roof was put on, and the pier and beam were "reinforced" i did find a 2x12 under the house that had dry rot. i was just concerned with being able to see outside through the siding, because ive never seen siding installed without anything behind it

Pretty common. Just think of it as extra attic ventilation.

That was pretty common practice in the older homes in this area.

I wouldn't be concerned with rot when you can see outside. You want to be worried after your walls have had insulation blown into them and the paint starts blistering off the side of the house.

I do "HouseHold HandyMan" type work in my area and often have to go into attics. I see this very thing on homes that are not any older than five (5) years old. Just frame it up, slap some Hardie board or vinyl siding on the gable ends and go to the next job. I've also seen the vinyl siding peeled off with just the slightest winds we get around here in S. Ga. Absolutely no climate or moisture control with this set-up.

I think I'm going to ask the owner to at least seal the holes with caulk. I think the vent in the gable will provide enough ventilation. I don't want to allow to much moisture into the attic. The house is in NE Texas, so it gets pretty humid

Are there any soffit vents? You would be far better off with a ridge vent and block up the gable vents.
A gable vent only vents the ends of the attic, A ridge vent will vent the whole area.

I wish there were soffit vents. Only 1 gable vent
