Regarding defending the physical look:
As I posted earlier, art is subjective.
What the individual, the OP is complaining about, did is not something I like but it is likely the individuals own self expression.
I'm sure that some would call it art (as many things are called art that doesn't appeal to me).
Some may even call it a form of free speech.
One
website gives the meaning of freedom of speech as encompassing not only the spoken and written word, but also all kinds of expression (including non-verbal communications, such as sit-ins, art, photographs, films and advertisements).
I do support the freedom of speech - even if I don't agree with it.
Now, what is being discussed is an issue for the Associations Board to address based on their covenants.
I have no idea what those covenants are.
I have no idea if the OP brought the issue to the board or, if he did, what the boards response and reasoning was.
The OP has not shared any of that.
One could argue the look is a nuisance.
However, nuisance is also a subjective term.
Based on the OPs statement that the Board won't do anything, It's possible that their board discussed the issues involved. Perhaps they even consulted an attorney or simply looked at finances and determined that legal action would cause more harm than good.
Again, I don't know.
I only know what I have seen which the OP posted.
Ellie quoted a post that is no longer available (at least I haven't seen it).
Perhaps my question to the OP (what did your board say?) was answered in that post. Perhaps not.
As I said, based on the photos provided through a link, it's not my cup of tea.
However, if I was on the board, I would:
1) defend the individuals right of expression vs. a subjective opinion (as subjective issues cause the most problems for Associations in a legal case)
2) do research to determine if what I see does violate specific covenants (vs. subjective covenants).
3) do research to see if the local authorities would be able to address the visual problem (health department, etc.)
4) recommend the board obtains a legal opinion on the issue and potential cost if it went to court
5) consider how this might affect the Association and members if legal action was brought and the media ran stories on it (as contacting the media would be the first thing I would do if I was that individual).
6) I would review finances and determine what might the Association be able to afford in legal fees.
This way, I could make an informed decision on what I would vote for the board to do.
