Is it legal for residential property bidding not to be publicized?

Whether the bidding for residential property is announced according to law depends on the property rights of the residential area:

1. If * * * has property rights, that is, it is shared by multiple owners, then property bidding is illegal, because according to the property management regulations, * * * property projects with property rights must be subject to bidding.

2. If a single owner owns the property right, it is legal not to announce the property bidding, because according to the property management regulations, a single owner can decide to choose a property company privately without public bidding.

Please note that the above situation does not include the situation where the owners' committee or the developer is the main body to conduct property bidding without announcement. The above information is for reference only. It is recommended to consult professional legal practitioners or consult official documents to obtain the most accurate information.
