The only obligaion that the homeowner has to lovers of the scenery is to make sure that the home is safely built and visually appealing.
I'm pretty sure that a guy that can build a ten thousand square foot home with ocean frontage will not build a tin roof shack with goats in the front yard.
As for safely built, that is the safety of the property owner, that is also the owners look out since he/she will be the one living in it.
I dislike, and fight against them every change I get, all restrictions to property owners that don't actually have safety of others as the main theme.
