Being as ecovillages consist of a consenting, autonomous populace, they are a place in which people can live according to a wide variety of agreed-upon unconventional practices. The experimental potential is great, though limited by the laws of the jurisdiction that the ecovillage is in.
Some practices that are not common in the 'outside world', but are common in ecovillages, aside from the defining aspects of an ecovillage, are:
- communal eating, beyond the scope of a single family
- a socialist internal economy
- decision-making that requires consensus
- prohibition of alcohol and/or tobacco from the premises
- use of bicycles as the main means of internal transportation (this is ecological, but is not a required aspect of an ecovillage)
Aside from the above common practices, there are other, more original practices that can be implemented. These include, but are not limited to:
- custom aesthetics: The community can have specific physical aesthetic traits. This can apply to the homes, the land outside the homes, people's clothing, and/or other aspects.
- selective membership: The community can admit or bar community applicants based upon whatever criteria it wants.
- selective breeding: The community can preferentially breed whatever traits it wants.
- custom child-raising policies: The community can implement nearly whatever policies of child-raising that it wants.
- custom morals and rules: The community can implement nearly whatever rules that it wants, under penalty of banishment or breach-of-contract liability.
