Odd issue with city inspector

[Bob Hank]

About 5 years ago I rented a house to a city inspectors (lets call him Joe) daughter. I did not know it was his daughter at the time. Over the last 5 years she has been a great renter and have had few issues.

Last week she was out of town and got delayed in another state with her job. I did not receive the rent on time and did not get a phone call saying why she did not pay rent. I posted a 5 day notice more or less saying pay or legal actions. She got back into town the next day, payed her rent with the late fee, and everything was fine.

The on Monday I called for a building inspection and Joe showed up. I ended up failing the inspection and no code numbers were given, just the issues. I researched the issues and could not find where anything was not up to code. This morning I stopped by the building department and talked to the head inspector. He looked through the paperwork, called the Joe, and then went to the house to see the issues for him self. After the head inspector looked around and check everything he passed it. I did not bring up that I feel that there is a conflict of interest or anything.

I feel that I have now stepped on the inspectors toes and at what point would you bring up the conflict of interest to the building department?
