Having trouble with a potential rental

[Chase Guelette]

Hey BP, I recently found a Duplex that seems like it would be a good investment if I can rent out both units. When looking at the property, I noticed that in the description(Found this house on Zillow) it said that the top unit could only be rented if the house was owner-occupied. I am investing in Lansing, MI. Are there any laws that would prevent me from renting out both units despite not living in the house? Thanks!
