Does the property bidding have to go through the property association?

Yes, but there is no mandatory provision.

1. If it is a government procurement project bidding, the management fee will be allocated by the government. According to the national government purchase order 18:

Eleventh bidding units shall organize bidding activities for goods and services in accordance with the provisions of these measures.

The purchaser may entrust a procurement agency to handle the bidding of goods and services according to law, or organize the bidding of goods and services by himself, but it must meet the conditions stipulated in Article 12 of these Measures.

Centralized procurement institutions independently carry out bidding activities for goods and services according to law. Other procurement agencies handle the bidding of goods and services according to the entrustment of the purchaser.

Article 12 A purchaser who meets the following conditions may organize bidding by himself:

(1) Having the ability to bear civil liability independently;

(2) Having the ability to prepare bidding documents and organize bidding, and having technical, economic and procurement management personnel suitable for the scale and complexity of procurement bidding projects;

(3) The procurement personnel have received government procurement training organized by the financial department of the people's government at or above the provincial level.

If the purchaser does not meet the requirements specified in the preceding paragraph, he must entrust a procurement agency to conduct bidding.

Therefore, if you meet the above conditions, you can bid by yourself.

2. If it is not a government procurement project, there is no such rigid requirement unless the owner strongly requests it.
