In the same series they post about how they wouldn't let the repair people or landlord on the premises and made multiple calls to code enforcement and county health department.  

The program's focus is to protect the health, safety and welfare of the public.

If you need any help I would communicate with the building officials to find out what they are looking for.If you think I could help you please contact me through BP at any time.  

Send them an official notice by mail and post one on the house.

Very dangerous and a threat to both his health and the overall "health" of your property.

I've written about it on BP in details and recently discussed it with one of the Ohio Health Directors in Columbus.  

The county clerk of court, official records search, will show you all mtg.s on the property.  

I think to accomplish my goals on this one I am going to have to 1)keep trucking along slowly now that I'm back at full health 2)find someone to "buy-in" with equity on this property as a return or 3)sell it 

The zoning official can tell you but also CCRS may play a role as well.

The net of this was I ended up offering another $5k to bring me up to $150 "take it or leave it" under the threat of the seller walking, which I highly doubted as they needed all proceeds to close on another property they were under agreement on.Bottom line is $150 was accepted in the 11th hour (pretty close to what time I got a signed extension on the appraisal addendum back as it was expiring the day I made the $150k offer), the downstairs unit is listed and being shown, upstairs is being served notice next week and the property  will be "officially" mine Monday!
