Yes. There are no 'living' provisions. Sleeping, cooking and sanitation yes, living? No the building is for working, employment, providing a service. You simply cannot live there. No one claims transient or permanent residence there, it would not be allowed by the owner (think fire chief/political subdivision head)
Forget for a moment it's a government building. A private company has a fire brigade, they fill a fire station with employees whom work for them. They do not come there for free, it's not a rented space. If they are living there are they then squatters? No, employees there doing the employers bidding. And, they can be told to leave whenever the employer decides. Can't you just be sent away from your 'living space'? I'm not going to get into the nuances of at-will and union contracted employees, but do you see the space is built for employees, not residents?
I know you disagree, I'm not trying to change your opinion. Im hoping to show employees are not 'living' at work, they are working.
