The special residential maintenance funds are specially used for the maintenance, updating and transformation of the main parts of the house and the main facilities and equipment after the warranty period has expired.

When a commercial house is sold, the buyer and the seller should sign an agreement on the payment of the house maintenance fund. The buyer should pay the house maintenance fund to the seller at a rate of 2 to 3% of the purchase price.

All owners agree that the maintenance base metal collected by the selling unit on behalf of the house is not included in the residential sales income.

The maintenance fund can only be used when the public parts of the property, public facilities, and equipment are overhauled, updated, and renovated after the warranty period expires.

Specific owners share the proportion of expenses according to the standard determined by voting rights.
