While the rule makes it clear that you have to keep your RV out of public view, you are allowed to park one out of sight in your garage.
It's common for HOAs to limit the time your RV can be parked in view of public areas to three days. That being said, some HOAs are more strict than others, with some allowing up to five days before they issue a warning letter or fine.
Many planned communities don't allow you to live in your RV on your own lot while you build your home. However, some communities will allow you to occupy an RV for a stipulated period of time. This may be six weeks or six months, depending on the HOA.
With few exceptions, HOA communities that provide RV storage won't allow you to use your RV as a guest house. Furthermore, this rule applies whether your guest is staying for a night or a week.
