Ok, to clarify, I have not seen the OP's CC&R. I am assuming there is a nuisance clause in there somewhere, always is. What I was saying is that from my experience of being on HOA boards for many years, I cannot see where doing something completely legal would be considered a nuisance. I have seen HOA boards get their butts in some pretty bad situations because of over zealousness in enforcing rules, real and imagined.
You cannot just pick a association members name out of a hat and say "It's your turn in the barrel". The HOA better have all it's ducks in a row when it decides to go after someone for some "perceived" infractions of rules.
This is where a good management company comes in, they look at all the legalities, liabilities and $$ it will cost the association and will advise HOA boards on whether or not it is wise to take action.
Like I said earlier, any fine for infraction you receive automatically entitles you to appeal thru arbitration. It is California law.
In my HOA, you have to be a real work of art to receive any kind of correspondence from the association, we like for neighbors to work out their differences before it gets that far.
Whenever my board receives a letter requesting an appeal, we just write it off and drop the subject. The person requesting the appeal has usually gotten the message and cleaned his act up by that point.
