Rental Certifications in Warren Mi

[Pillar Jane Lagrito]

Hi all! I've been searching for investment properties in Warren/Eastpointe area of Michigan and have cme across some propertirs, which I beloeve, may have unpermitted addtions (bathroom or bedrooms). How does that affect the application for the certificate of occupancy or rental certificates? Will you not get certified because of these issues? I'm assuming the additions are unpermitted since tax records are different from listing info. Thanks in advance!
