Types of communal housing arrangements, such as communal and cooperative arrangements, can help promote affordability by sharing household costs across larger groups of people. While many of these housing arrangements are developed privately or organically amongst community members, there may be a role for municipalities to encourage their creation. For example, interest in co-housing for seniors is growing in other parts of the country and tiny house villages to address homelessness are becoming more common. Further study could identify potential barriers to creation of communal or cooperative housing (such as limits on unrelated persons sharing a home), as well as incentives in land use regulations and taxation (such as density bonuses).
