Sort of. The building was built as a dual-purpose building to save on the cost to build. Those big metal buildings are cheap to put up and a lot of people build into them over time (live in it as you build up around you is the normal strategy, either with an RV or by starting with a room and bathroom).

Those big metal buildings also sometimes manage to fly under the radar for developing land without permitting, since you can put one up on your own land for storage.
