These buildings are supposed to be structurally inspected every 40 years, with interim inspections for other areas (electrical, roof, etc.). I’d say that schedule is going to change! Almost all of the buildings in this area were built around the same time, so they’re all possibly damaged (not only subsidence, but the salt air and water attacking the metal structural parts).It turns out that an identical sister building was built a few blocks north of this one. If I was a tenant, I'd be making plans to move.
