Is it a breach of contract if the property is not built?

There are several obvious violations here. First, the water and electricity are impassable, and the conditions for building houses are not available. Second, after building conditions are met, the property will cooperate with the developer to issue building notices; Third, the property fee is collected every month; 4. The property fee shall be collected in advance, which shall not exceed 12 months; Fifth, the decoration deposit is not allowed to be collected; Sixth, the time from the date agreed in the contract to the date of meeting the building conditions and receiving the building notice (here refers to the date on the building notice) belongs to the development company's breach of contract. The development company should compensate the owners for certain expenses. Seventh, the property company has no right to detain the owner's key without giving it to the owner. Eighth, there is no need to pay the house fee when handing over the house, except for the property that takes the owner to handle the project, such as gas and cable TV.

If the building meets the building requirements, the building notice has been issued, but it has not been completed due to the owner's own reasons, the property management company will charge the property management fee (called the house inspection fee by the development company) in the month after the building notice is issued, and this fee can be appropriately reduced.
