Floor trusses separating and floor sagging (Help)

[Igor Messano]

Hi everyone,

I have a unit that is in a 2 unit building of which each unit has an owner. The outside of the building is under an association but the inside is fully owned by the 2 owners (I am one of them). I have the top unit which we remodeled the kitchen 3 years ago. When we remodeled we decided to put down tile flooring in the kitchen, living room, and hall way area (open floor plan). We noticed that a section of house the floors were not leveled but instead of tearing everything apart the sub contractor just compensated and leveled as he tiled.

Fast forward to today we get a call from the down stairs owner that they were having cracks in the ceiling and once they removed to repair they noticed that 2-3 trusses were failing at the connection point. Our concern is that the sub was not licensed and that somehow our remodel will be blamed for what is a structural issue. The tile floors added weight compared to the old vinyl floors but I don't see how the weight of tiles aren't an expectation when building. The building is about 35 years old.

Any suggestions on how to best proceed here to ensure we aren't left holding the bill for this? In our mind this will likely not be recoverable from the builder or association but hopefully a shared cost between both home owners insurance.
