After the renovation, the property notice required rectification, because the basin was moved outside the bathroom. However, it is clearly marked on the property drawings that the basin is moved out.

Your renovation can only be carried out after you submit all the information, pass the property management audit and issue the renovation permit. It must include the renovation plan ... If it conflicts with laws and regulations, you must rectify it, but you can claim that you are responsible for all the losses caused by negligence in property management. Because they are responsible for reviewing your decoration drawings.

1. The outward movement of the basin does not belong to the outward movement of the toilet. In addition, as long as the acceptance conditions are met, the acceptance can't be refused downstairs. It has nothing to do with whether your basin is moved out.

I don't think his complaint to you has caused the relevant department to order rectification. The premise is that you must deal with the drainage without causing losses downstairs. Ps: Why did you know that your basin was going to move out of the downstairs? Did you change the drain pipe?

4. The property management is worried that you will have drainage problems in the future, which will lead to water leakage downstairs, and you will not handle it. This is not easy to explain downstairs. Property management won't ask you to rectify, just want to bear the maintenance responsibility since the basin moved out in the future. If you decorate, the deposit will be refunded after acceptance, and the property management can't help you. However, the property management just wants to take a piece of paper and make peace with the downstairs. Why bother them?
