Floor Joist Support

My fiance and I visited a home today that is roughly 80 years old.

While inspecting the basement, I noticed something odd about the floor framing:

The concrete foundation wall is topped by a sill plate, as I expected. The header plate (2x8 or 2x10 on edge, I wasn't paying enough attention) was very close to the inside edge of the sill plate, about half an inch away. The floor joists rested on this exposed half inch of sill.

I thought for a moment that perhaps I was mistaking some blocking for the header plate, but one of the floor joists wasn't quite square, and I got my finger between the end of the joist and the header plate. This particular joist was resting on no more than 1/4" of the sill plate.

The floor joists ran the width of the house, and were supported in the middle by a tripled joist supported by a wooden column.

Is such header placement unusual? Is it safe, assuming the header plate is nailed to each joist? I had an awful vision of the first floor collapsing into the basement.

Any insight is appreciated.

TIA,

Bill in St. Louis

If this is a home you're considering to purchase I would recommend hiring a qualified/certified home inspector to evaluate the home for you.
