people not on lease living in rental houseWe have discovered our tenant's daughter, who is listed on the lease as living their from time to time) and her boyfriend are now living at our rental house full time. The daughter never signed the lease and we know nothing about this boyfriend. this is a small home in and with twice as many people living there as we agreed to, we're worried about the double wear and tear on the place. We don't want to evict these tenants, but we do want to do a background check on these other folks and get them officially on the lease. They have also added a second dog when only one is on the lease.Any suggestions for how we should proceed? What rights do we have as landlords in Cook County, Il for this kind of situation?Any advice from seasoned landlords would be greatly appreciated.August 19 2011 - Park Ridge00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
