I rented a home in an HOA for a few months. It was kinda nice, actually, but it wasn't a terribly strict one. They didn't say anything about the type of car, business or advertising. However, they did not allow anyone to park on the street overnight. Silly, because you could park there all day long and they really only gave tickets on one or two nights of the week (and it was usually the same nights!). I happened to have a Sacramento Police officer living next door. He brought his patrol car home every night and parked in the street and no one ever gave him any problems for it. My husband and I think that since it was the end of the street, it just looked like he was parked there while on patrol and people felt safer because it deterred malicious mischief. And they were pretty hard on sign violaters. I never tried to pass out fliers because we didn't live there very long.
