the roof rights are deeded to me...and if i had a leaky roof, it would either be the condo insurance that would cover it, me, or my builder considering its new construction and its under warranty. There would be no assessment. Also if it was the law ( which it is not ) how would a post like this even exist? I normally would not take the F&**the neighbor approach but we have had some other issues as well that are not related to this.

I just bought a place and we ran into the same situation ( although we bought the top floor of a 2 unit condo/brownstone). Our condo rules say nothing about covering 70% of the area with rugs etc. And while we have put carpet in certain areas I am not about the carpet my entire place as one reason I bought it was because we loved the hardwood floors. My downstairs neighbors and I don't get along but oh well. In my opinion, this is something he should have checked out before he bought his place. I believie he has since sound proofed his place.
