HOAs are such a fascinatingly American thing. They seem to cause no end of annoyance for those living in them, and have few to no positive effects (at least, we don’t hear about any positives), yet they persist.

Can those who are adversely affected not do anything about their local ones, or is it actually a case that they’re not too bad for most people most of the time?

The purpose of an HOA (in theory) is to divide the costs of land maintenance across land owners.

In practice, HOAs are routinely abused for rent seeking and stigmatization of minorities. But that’s not a problem specific to the legal arrangement. It’s a consequence of the managers and members.
