Senior living residents are protected by numerous state requirements. For example, assisted living is regulated by every state in the country, and the exact regulations and licensure requirements vary from state to state. The sometimes subtle differences in regulations contribute to the wide range of senior housing models available. State regulations are consumer-based and seek to maximize independence and choice, enabling senior living providers to focus on innovative solutions to meet their particular markets. Rather than implement uniform regulations that would result in cookie-cutter communities, states have explored unique approaches, borrowing from the successes of other states and avoiding the mistakes of others.
