Buying a park with older small lots

[Corey Woodruff]

The park is in Michigan that I have under contract for 375k with 50k down, The lots are 50-60 ft, what I am wondering is who do I contact about moving in bigger homes, I called the local city hall that the park is in and they had no information to give only to tell me that MH parks are state certified. So do I call them? What branch do would I call to find out what hoops I have to jump through.

Also the park is grandfathered in and not up to code so is the state going to make me bring the park up to code to be able to bring in new homes?

In Cali it's the California Department of Housing and Community Development. In Ariz it's the Dept of Transportation the last time I was a licensed MH contractor which was about 10 years ago. In Florida it was the DMV. Also the last time i was a licensed MH contractor which was 2004. 

All that stated I just did a scant Google search under "who regulates mobile home parks in Ill and here's what I found. Should be your answer.

When in doubt Google it out.
