Question on permit and zoning

**Hi , **

**I’m under contract on a park and started doing my due diligence. When i contacted the city regarding permits and zoining they emailed me the below : I want to just make sure if i’m ok with this as this is my first park and I’m just bit nervous on these issues . any advice is really appreciated . ****

email from city :
"The property is zoned as Medium Density Residential (RM), the mobile home park was created legally. Attached is the zoning ordinance on residential districts.

Certificate of occupancy is issued for new buildings & is from the Building Dept. You may need a change of ownership/change of tenant if you are purchasing, this is from the Building Dept as well:"
