Buildings - Maintenance?

[Snogmonkey]

I've seen various people say that if you're having trouble with economy, you should tear down buildings you don't want/need. Is this simply to get the small recoup destruction cost? Or is there some hidden maintenance cost that drains the local economy? I was under the assumption that once you put in the initial cost and time to build it, a building was gravy unless you have to repair.

Well, for example, after gunpowder and I'm making various cannon, I usually start tearing down siege equipment buildings. No real need for them anymore for the most part, and you'd be surprised how often the AI build managers make the things when you aren't looking.

by the time you reach gunpowder age, you should be so loaded, that you shouldn't need to be so conscious of money. I still keep the siege equipment buildings coz ballistaes ROX!

Ok but is that just to reduce the clutter in your unit options and city window? Or does it take say 300 gold per turn to upkeep around a tier3 siege engine building?

There is no maintenance cost for buildings at all. It will give you a slight and quick cash infusion is all, and if you don't need the building anymore, why not?
