Where to Find Zoning information for specific home/City?

[Bryant Amundson]

Hello,

My wife just had a house pop up on her radar due to a friend of hers posting constantly on Facebook... 
It is in Mound, MN and it "seems" like a good deal and in our budget. We would live in it first then rent it out after a couple years. My question is, where do I find zoning information to know if I would be able to turn it into a duplex after we move out. It is currently a single family home. 

If anybody in Twin cities, or Minneapolis, Minnesota, lake Minnetonka region what to chime in with their experience that would be great. If not, then general info about where to find said info would be much obliged.
Thanks Ya'll
