I think landlords, however big or small, should advise tenants about the Ames ordinances relevant to rental housing, but some don't do this. Here are the three big ones: one, depending upon the zoning area the house is in, you cannot have more than three unrelated people living in the house; check and see what zone your house is in. Sure, some people get away with more than three, but the fines have increased, and now I believe it will cost the tenants $500 bucks if they are in violation. Two, do not park cars on the front lawn; you can do this temporarily, I believe, on the side yard but not the front. Three, make certain your garbage cans or containers have lids that fit snugly; this is to keep out critters and of course to avoid spreading garbage around the neighborhood should a container fall over.
