Friends from the legal profession helped me. Does my home decoration property management office have the right to interfere?

Your behavior is legal, and you have not violated the interests of the collective or others because of your personal interests. Also, it depends on whether your property management contract stipulates the unified appearance of the community.

That is, property management has no right to interfere. For the tasks (contractual obligations) assigned by property management to all owners, your actions have not hindered their obligations, that is, they have not hindered the life (contractual rights) of the owners.

It's mainly annoying to make the kitchen balcony. It's best to return your exhaust pipe to the place where everyone discharges uniformly. As long as it's okay upstairs.

Humble opinion, careful reference
