Some highrises are advertised as long-lasting, for example with "200 year concrete" and so on.[0] However, I think this is mostly marketing fluff -- if a company thinks they can make more money by tearing down a highrise and building a new one, they will not hesitate to do so, and often do. It seems that historically most highrises don't last longer than ~50 years. With new construction techniques and materials, maybe that will change. Smaller apartments are even more ephemeral. The official service life for apartments according to the tax code[1] is only 20-40 years, depending on the construction material.
