Building multifamily on existing owned lot with home but zoned CG

[Eneg R.]

Hello 559. I've come into possession a home that sits on a 9000 lot size around Highway City. I checked zoning and its zoned for CG. 

Some data I got shows neither single or multi unit residential is permitted, but there is a single house currently on the land and has for decades, in use, paying property tax, etc etc. 

Is there anybody familiar with zoning and things like this? Can I tear down existing home and build like 2 or 3 units on it? 

This is data from the city
