California has an abundance of good weather, movie stars, celebrities, social media influencers, and many of the most expensive homes in America. It also has the most "common interest development" residents of any state in the nation. These residents live in homeowner associations (HOAs) and planned communities (PCs), and they account for roughly 35% of the state's population. In fact, as of 2022, there were almost 50,000 HOAs and PCs throughout the state with a total population of just under 15 million residents.
