If you wanted to turn it into proper living space, I assume you'd have to conform to your local codes.

We plan on living downstairs and fixing/renovating the upstairs so it is up to code.

Zip codes worth checking out or that I should stay away from?  

Since the outer doors to the buildings the apartments are in (4 units per outer door) have a common key, I now only need one key and my master code to access all the units.

@Samantha Lotti Yes, I pick a certain zip code.

Our market is very diverse and one can't sort by zip codes.  

In the past, I focused on one zip code.  

If you subdivide it, you will have to meet all the regulations of the zoning code and the subdivision code, e.g. minimum lot size, etc.

Bottom line for me would be it doesn't violate city code, damage grass, violate HOA and presents no hazard I would try to look beyond "I don't like it"   I have tenants that do things I don't like but that doesn't mean they should not do them.
