There could be a number of departments, however I would find out if you have a land bank and start there.

To all my fellow Wisconsin landlords (or future landlords like myself):I don't remember how I came across this article, but apparently the Wisconsin Department of Agriculture, Trade and Consumer Protection creates the guidelines for the Landlord-Tenant relationship.

@David SoestCheck out the site Gosection8.com to post properties also check on HUD.gov on rules for handicap property and also check your local Housing Authority inspection department. 

I have also spoken with every State Department and my Lawyer about licensing, and from what I have been told it is not required.

I think your best bet is a state directory from a state agency (department of revenue or taxation) or state-level assessor association.

@Marcus Walker You can always look up crime maps and statistics from your local police department.

Thank you @Rachel Rodriguez as, a smaller sales department at my nine-to-five job also uses SmartSheet.

@Atwan Kwan Be thankful your departing tenant alerted you to this issue.

You can then start the process of talking with the city that the property is located in (talk to the planning department) find out what you need to do to get it to the next step.  

Also, for future tenants, check with your city water department.
