I have no idea if such a law exists in Illinois and whether it applies to a 7 unit.The fact that you didn't deliver the $5,000 to him suggests that --- even if you had an oral contract --- it's too late to enforce it.

I called the city to explain (I also let my realtor know as a courtesy so she could let the buyers' realtor know).In extreme eyesore situations, government gets involved and code enforcement liens on the property can add up over time.

How the legislation and regulations are written and interpreted will be a big factor in whether it is worth your while to accept pets.Here in NB, we are allowed to discriminate and not allow pets, but other jurisdictions (ON) that appears to no longer be the case.
