Thread: Multiple city halls?
Nope. One City Hall per city. City Halls can't be placed within 1000m of another City Hall, either.
Thanks.
Didn't think so. But, like I said, if I didn't ask.... 
I don't think it will let you place another near yours.
Because of the limits on how far citys have to be from one another and evenif you could place two city halls(which i'm pretty sure you can).I don't think that would by pass the limit rules because after all the city hall doesn't belong to you it belongs to city and the mayor just has control over it for his term. First thing that happens when you go to place city hall is it wants a name for new city.
And its been a while since i started my city but i beleive you have to set a city hall 1k away from another city hall. So i'm going to stop rambling and say no i won't work.
Sorry, if my ansewers were not direct enough but i hope i have been some help if all else fails just try to set the city hall. You'll get your ansewer really fast 
Wondered the same thing myself, a couple months back. Wanted to drop a second to use as the New Haven Municipal Court building.
Alas, only one per city.
