Rental license?

[Kyle Soderman]

I found something interesting about my city today. Apparently you must license your property as a rental property prior to having tenants. This has some fees associated with it. This makes sense. The thing I'm more surprised about is that St. Cloud, MN requires a landlord to go through a rental licensing class in order to rent out a property. I also believe there is some sort of annual fee you must pay in order to keep your license. 

Is this true with most cities or is this unique to my city? I have just never heard of this before.
