What kind of building needs property management bidding?

According to the provisions of Article 3 of the Measures for the Administration of Bidding for Early Property Management (Provisional):

Residential and non-residential construction units within the same property management area shall select and employ property management enterprises with corresponding qualifications through bidding; If the number of bidders is less than three or the residential scale is relatively small, with the approval of the real estate administrative department of the district or county people's government where the property is located, a property management enterprise with corresponding qualifications may be selected by agreement.

The state encourages other property construction units to choose property management enterprises with corresponding qualifications through bidding.
