My question involves landlord-tenant law in the State of: CA
I purchased a first floor unit in a multiple dwelling complex. The first 6 month was nice, then I started to hear all kinds of noises coming from upstairs. Running, jumping, chatting, dropping things on the floor, sounds like they do all of their activities on the floor. I complained to the neighbor and HOA, and found out that they installed hardwood floor. The tenant upstair said that most of the noise is caused by their way of living come in contact with the floor, and there's nothing they can do about it. The HOA have certain regulation about sound isolation when install hardwood floor, however the regulations are vague and ambiguous. They could have faulty sound insolation, but if the regulation was written with holes, they can easily get away with it.
I am trying to go after these people through small claim or civil, but I am not sure who am i really going after? Should I hold them responsible for making the noise or the HOA for not setting up the right rules for sound insolation?
i know i should avoid this at all cost, however these people just don't stop. Even if I sell my condo, who is going to purchase with all that noise.
Thank you all very much.
