Write rules to manage situations, not control people. Everything you write, you will need to enforce at some point. There will always be shareholders who break rules because they are just going to do whatever it is that they feel like doing, but everyone else will be governed by a rule written to control the few. try to not write too many. House rules are for the management of enabling people to live together in a balanced, fair and respectful way, and to protect the property for the benefit of all.
