On-Site Maintenance Code of Conduct?!?

Hi Ya'll... I know it's been a while since I have been on but I have been so busy but not too busy to ask for some much needed help I recently moved off site with my family which opened up my apartment and recently my maintenance man would like to take over the apartment. Of course we have some concerns and would like to make sure that he isn't just following the rules but leading by example.. Living in a fishbowl is not easy for everyone but we expect a lot. I am curious if any of ya'll have maintenance living on site and if any of ya'll have any addendums that you have created in regards to a code of conduct. Any ideas would be great too!!
Thanks everyone!!

Maybe I'm not understanding the question, Chrissy, but why would your maintenance guy have a different code of conduct for living on site than someone would have from the office living on site? Did you have a code of conduct while living there that could apply to him?
