Liability new-build condominium

Hello,

My parents bought an apartment in a large new development project (70 new apartments are being built) a year ago. In the shell construction state, they requested an air conditioning system, and the responsible employee commissioned the air conditioning contractor. We regularly checked the apartment and noticed early on the air conditioning lines that were installed in the bedroom (see photos). From the beginning, we said that this could not remain as it was. At the first inspection, we were finally told that it was our problem.

My father meanwhile had phone contact with the air conditioning contractor, who wanted to route the lines from the outside, and this had apparently also been approved by the first site manager, so the lines were installed on the outside of the facade. Shortly after, however, there was a new site manager who demanded the dismantling. The costs incurred by the construction company were claimed from the air conditioning contractor, but my parents are still being charged an additional 1000 euros for the dismantling. I am of the opinion that this is not lawful; can you help me? The official handover of the condominium is scheduled for 14.12.

What is legal is stated in your parents' sales and order documents (what was ordered? Which follow-up work will be carried out by whom?) and should be inquired about with a lawyer. I have no idea why he executed it this way or that. But horizontal slotting for these cables would not have been an option. The homeowners' association (all owners) can object to external installation. In this respect, it may actually be the case that now a drywall installer or painter has to come to cover the cables. Such things should be communicated, who then commissions it. The craftsmen and contractors generally dislike special requests in 70 apartments. They only cause work and trouble.

You should clarify which site manager made which statement when and whether and how this was done in writing. Then you need to clarify what execution was agreed upon between your parents and the air conditioning installer. And then you could break down who is responsible for what here. I could imagine several problems here: 1. You did not specify in the offer how/where the cables are to be laid. 2. The first site manager may have agreed to the whole thing contrary to his responsibility.

Do you have it in writing? If not, tough luck. Then you only have to discuss the execution. It looks bad that way.
