It could possibly be subdivided but unfortunately the cost to bring it up to modern day code might make that financially difficult. It is just easier to build new modern buildings for more manageable sizes.
A long time ago I talked to a guy that did radio controlled planes. They wanted to have races and stuff in one of these but there were insurance reasons that they couldn't because the buildings didn't meet current code. Its a shame, that would have been cool.
@y_sasaki Interesting. Thanks. Maybe when we all get our jetpacks, these dirigble hangars could become indoor jetpack lounges or just an indoor space to try out the jetpack. Maybe not. Or a place for testing drones.
We have similar former Airship hangers in Tustin, Orange County CA. I've heard it is difficult to find new purpose because those structures do not meet todays safety standards, such as fire or earthquake.
