Not necessarily. Things like "where do pipes run" so can get tricky along with code requirements for access.

There's a NYT article on the challenges about this from a few years ago: So You Want to Turn an Office Building Into a Home? -- Here’s How to Solve a 25-Story Rubik’s Cube https://www.nytimes.com/interactive/2023/03/11/upshot/office...

IIRC, that article mentioned older buildings tend to be more convertible to residential, because of their layouts, and modern office buildings (with giant open floor spaces for seas of cubicles) are almost impossible to convert.

There should probably building code changes to ban the latter type of office building, and keep the space more flexible and convertible to residential. A big plus is the resulting office space would probably be nicer to workers.

Article from 1 month ago on how conversions have become much more feasible with some clever hacks: https://www.wsj.com/real-estate/commercial/nyc-office-reside...

While converting it is not economical, class c office space (which is least desirable) demand is probably gone in this market due to lackluster demand for office space; the value of the building will get zeroed out by the market, at which point it can trade hands, be demo'd, and new residential can go up in its place.

You can think of class c office space, broadly speaking, as oil wells that have very little life left, and get bought up by folks who intend to extract the cashflow until they dump the externality on the public government and taxpayers (like abandoned shopping malls).

A recent example in St Louis is the AT&T office tower [1] [2].

(conversions when the economics pencil out, haircuts for investors when they don't and more investment is needed to wholesale replace a structure)
