Feel Free to connect about landlording in Cook County.

You guys are making me glad I don't have any LTRs.I did have guests who checked in on Christmas Eve and at 1am on Christmas Day asked me to provide new pots and pans, as they said mine were scratched and they didn't feel safe cooking with them.I wound up getting them new ones the following day (I won't even get into how incredibly sick I was at the time, too).  

There are many different ways to manage a self storage facility.

@Pat Baggett - For Chicago and all of Cook County can type the address into http://ccrecorder.org which will show you recorded docs like mortgage, foreclosure and title info. 

I checked everything I could think of anyway, went up into the attic and checked for moisture, checked the basement, stuck moisture probes in the walls, checked the dryer vent, and quizzed them about if they run the shower bath fan and how much they boil water for cooking.

If someone can survive five years in the same position in the same facility, they're invariably more reliable as a tenant than other people with similar income.

Id love to talk to some professionals who have built/bought/managed self storage facilities. 

Here is info from an older post that might help with your research.That probably stems from the definition of a "family" in the City of Pittsburgh Zoning Code [see art. 9, ch. 926, § 76(b)]:A group of not more than three (3) persons who need not be related by blood or marriage or adoption, living together as a single housekeeping unit in a dwelling unit, and shared common facilities as considered reasonably appropriate for a family related by blood, marriage or adoption; in either case exclusive of usual servants;So I guess any house zoned as "single family" can technically only have one such group living in it.

Far to the side, put in a RV/vehicle storage facility.
