That is such bullshit. It is not their house! Does it actually ruin their reputation? Or would it if people knew people could do anything to their own damn house? Still, I find not being able to do such things to my house without their permission silly. What is the most minor modification that is disallowed?
In my experience the point of such covenants is not about the reputation of the builder, it's about preserving the character of the neigbourhood... it can be inconvenient for you, yes, but your house is more valuable if you know your neighbours aren't going to ruin your view by turning the front of their house hideous...
Yeah, I was thinking of this and I thought this was mainly the reason but then they should start being honest about it, IMO. I wonder what modifications this disallows that do not actually do any "reputation ruining".
