How does cohousing provide for residents of different economic means?

Some states, counties or municipalities require developers of multi-family housing to have a certain percentage of the new units meet a standard for “affordability.” People in cohousing usually welcome this, and often wish they could make even more than the required percentage affordable. Unfortunately, unless the developer can get public or private subsidies or grants, a community can build only a limited number of affordable units without significantly driving up everyone else’s costs.
