What would happen in this case?
Lets say you own half of a duplex, you decide to rent it out, and you later find out that it was being used as a grow op and has the usual mold damage/hacked up utilities, etc.
Would they condemn your half only or both?
What if mold got into you neighbors side of the duplex as well? Would the neighbor have a legal right to sue you?
Disclaimer: I do not own a duplex, or a grow-op, or know of anyone who has. I'm just curious.
