Does that mean I'm all set and can break it up in to separate units, or do I need to get a permit or rezone or other things?

@Shayan Sameer Yes in case the projects do not work as expected you will have an issue with paying off the HELOC  on  your properties unless you do a cash out refinance and then the risk is not so much as there is no second lien(HELOC)

The owner can designate a host who shall be responsible, and authorized, to act on the owner's behalf to promptly remedy any violation of these standards or the permit.

@Craig Oram this is a common issue.

A clean U&O means the Seller doesn't have to do anything.The home inspector is a different issue.

I am having issues with one property I own in Cahokia.  

CA has it's upsides and both states have insurance issues.

if its only one sub it could have been an oversight. 3 years  is this because permits take so long..

If a 10 year investment horizon is an issue than this is definitely not for you.  

If the damage is minor, again I think the tenant can simply claim the quality of the appliance was poor and they have the door-seal quality issue to further back up this claim.
