Yes, in known earthquake zones I would expect some testing, but in places like NYC I'm not sure.

In a few minutes searching I didn't find any reference to required testing of old buildings for structural or materials integrity.

In many parts of North America, testing and upgrades are only triggered with a change of use, or if required by buyers during sale of a building. The state does not maintain any kind of testing program of private buildings.

One exception is the mandatory retrofit programs implemented by some cities like San Francisco and Los Angeles.
