Site rules are often in place to reinforce good management of a site and to encourage communal cohesion. Although it is not mandatory for a site to have site rules, they are intended to make sure that everyone living on the site is complying with a collective standard.
With site rules in place, disputes between residents can often be more easily remedied or avoided altogether. Site rules typically cover, car parking arrangements, permissions to have pets, the required age of residents on the site, etc.
Site rules can only be changed or implemented by going through the site rules making process.
