Thanks for responding all - in short I screwed up and need to do further digging.
So, I screwed up as a first time home buyer and did not take measures to ensure that I can continue the argument for having my floors repaired/etc by HOA or Penthouse owner. I was simply excited, which is not relevant anyway. This is simply potentially an expensive lesson learned the hard way. Therefore I am seeking expert advice from all of you. Much appreciated by the way.
I need to comb through the documents in more detail, covenant, rules, etc. So far I am finding descriptions that basically state the HOA is repsonsible for the infrastructure of the building. Owners are responsible in wall of the units. If an owner is doing something that causes damage to another unit, they are responsible. However, if they are utilizing a structural feature, like a gas lined bbq and water from rain is leaking through the pipe's ceiling hole, it seems to be an HOA responsibility. I don't see language regarding transferrence of issues yet. I'll need to read more but have been busy.
Something that may be pertinent, is that my neighbor received verbal admittance of responsibility by HOA president and Penthouse owner. They both state they will follow up with both HOA building insurance and the penthouse owner's insurance to cover damage caused by structural leak of pipe and roof. Note that previously, the penthouse owner tried fixing but the fix failed. He is also on the HOA board. I found out the board also met privately, and have confirmed that they do not plan to extend the same offer to me. Although it was clear there were structural leaks, and have in the past replaced previous tenant mattresses as they were damaged from leaking ceilings, they wont cover cost of any repair to my floors as it is unclear if the currently leaks have caused new damage. This makes me think they know they're responsible, but think their insurance[s] will be unable to cover any claim.
