我也觉得只要是只有1份lease，而不是分组，就可以，HOA的目的可能是减少停车数量or杂乱人员，

如果三个朋友互相熟悉，住得好，停车位置足够，我觉得没问题（不过我也同意朽哥说的这样的租客可能不稳定）。你和他们就签一个合同，任何一个人都要100%负责rent。另外，chatgpt提供了一个比较宽松的定义：

Definition of Single Family: The exact definition of "single family" can vary. In many cases, it refers to individuals who live together as a single household unit, sharing living expenses and responsibilities. This could include a traditional family, but it might also include a group of friends who live together as a household.
