The idea of tiny homes to address homelessness has been around for a little while and some churches are making it a reality:

On vacant plots near their parking lots and steepled sanctuaries, congregations are building everything from fixed and fully contained micro homes to petite, moveable cabins, and several other styles of small-footprint dwellings in between.
Church leaders are not just trying to be more neighborly. The drive to provide shelter is rooted in their beliefs — they must care for the vulnerable, especially those without homes…
Some churches’ projects are already up and running, while others are still working toward move-in day, like the Church of the Nazarene congregation in St. Paul, Minnesota, which is assembling a tiny house community for chronically homeless people with local nonprofit Settled…
Houses of worship not only have land to spare, Medcalf said, but are positioned to “provide community in a way that really is humanizing and is a part of anybody’s basic healing and recovery.”
I like this idea for the reasons cited above: congregations have a mission to serve, have land, and are often established and respected organizations in communities.
As noted elsewhere in the article, churches might not feel equipped to tackle all of the issues involved with housing – so they can work with organizations in this sector – and neighbors can register complaints – as they often do about any new housing in an area.
Thinking more broadly, given all of the housing needs in the United States, does this hint at a growing willingness of religious congregations to consider addressing this issue?
