case, the treads are supported in notches cut into the stringers. Look carefully at the photo and the close-up (item 2), the treads have pulled out of
the stringers and are being held in place by nails that were driven into the edge of the treads. One tread (item 3) has lost so much support on the right side, that the tread is unlevel.
It is only a
matter of time until somebody steps on one of the loosened treads, the tread falls out, and a serious accident occurs. It is important to be sure that all stairways are kept in good repair. Be sure that your
home inspection engineer verifies the integrity of all stairways.
