[Direct answer]In the Beijing area, developers' failure to deliver on time and substandard housing quality constitute two different types of breaches of contract, and the paths to seeking legal redress are also different. According to Articles 577 and 582 of the Civil Code of the People's Republic of China (effective January 1, 2021), if a party fails to perform its contractual obligations or performs them in a manner inconsistent with the agreement, it shall bear contractual liabilities such as continuing performance, taking remedial measures, or compensating for losses; if the delivered subject matter does not meet the quality requirements, the buyer may request the breaching party to bear contractual liabilities in accordance with Articles 582 to 584. Therefore, in the case of late delivery, the buyer can claim breach-of-contract penalties as stipulated in the contract, and pay attention to verifying whether the grace period clause is applicable, whether the grace period can be cumulated with other extensions, and whether the defense of force majeure is valid. In the case of substandard quality, first check whether the delivery conditions stipulated in the contract have been met. If the housing does not meet the agreed standards, it constitutes late delivery; if the housing has been delivered but there are defects, the buyer may require the breaching party to repair within a specified period, and if the repair is not completed within the time limit, the buyer may claim a price reduction or compensation; if it seriously affects normal living and use, it may constitute a fundamental breach of contract, allowing the buyer to request the dissolution of the contract and the return of the housing. In practice, a key prerequisite is to incorporate the delivery conditions and quality standards into the contract and retain evidence during the acceptance process.Real estate transactions and construction projectsThe column provides specific explanations on the delivery and quality protection of commercial housing.

1. Problem background and typical scenarios

Buyers who consult such issues are often in two situations: first, they fail to receive the notice of delivery for a long time, and the progress of the project is stagnant; second, they have received the house, but find problems such as seepage, hollowing, cracking, and unfinished supporting facilities. Common concerns include: how long the delay can claim the breach of contract penalty, what level of quality problems can lead to the withdrawal of the house, and how to respond to the developer's defense of force majeure. In practice, a common problem is that the delivery standards in the contract are vaguely defined, making it difficult to provide evidence for quality disputes; therefore, it is often more effective to clarify the delivery standards and supporting commitments when signing the contract than to protect rights afterwards. Another common misunderstanding is to confuse quality problems with delayed delivery: in fact, if the house fails to meet the agreed delivery conditions, it constitutes a delay, while defects that occur after delivery belong to the responsibilities of repair and compensation, and the basis of claims and methods of providing evidence for the two are different.

II. Key points of contention

Focus One: The specific content and proof methods of the contractual delivery conditions. Focus Two: The application of the grace period clause and whether it can be cumulative. Focus Three: The establishment criteria and burden of proof for the defense of force majeure. Focus Four: The agreement on the standard of the penalty clause and judicial adjustment. Focus Five: The identification method of quality defects and the fixation of evidence. Focus Six: The choice between repair requests and price reduction/compensation. Focus Seven: Whether it constitutes a fundamental breach of contract and the conditions for terminating the contract and returning the house. Focus Eight: The handling and connection of the mortgage loan contract in the case of returning the house. In addition, attention should also be paid to the verification methods of compensation for decoration and ancillary facilities, the determination of responsibilities when supporting facilities are not completed, and the burden of proof requirements for developers claiming that the conditions for handing over the house have been met.

III. Professional analysis by Henglue Law Firm

From the perspective of practice in commercial housing disputes, the effectiveness of protecting rights depends on three preliminary tasks. First, clause review: Extract the delivery time, delivery standards, grace period, and default penalty standards from the pre-sale contract and supplementary agreement, and form a timeline and clause comparison table; this step is often overlooked, but it often determines whether the claim can be established. Second, evidence fixation: Payment receipts, move-in notifications, completion and acceptance filing materials, on-site images at the time of delivery, and communication records between the parties constitute a complete chain; for quality defects, third-party inspection reports and communication records should also be provided to avoid relying solely on verbal descriptions. Third, anticipation of defenses: Common defenses raised by developers include force majeure, cumulative grace periods, and the claim that the house has already met the delivery conditions. Counter-arguments must be prepared in advance of litigation. A case of default penalty for delayed delivery handled by our lawyers illustrates this method: The client signed a contract to purchase a house in a certain residential area and agreed on a delivery deadline, while granting a 90-day grace period through a supplementary agreement, stipulating that after the expiration of the grace period, a default penalty of 0.01% of the total paid housing price per day would be imposed. The developer claimed that the delay was due to the pandemic, bad weather, and government meetings, and requested that the grace period be cumulative. After studying the contract and supplementary agreement, the lawyer clarified the core provisions such as the delivery time, grace period, and default penalty standards, collected payment receipts, move-in notifications, and completion and acceptance filing materials to form a complete evidence chain, and responded to the defenses point by point: The pandemic was already a normal situation before the contract was signed, and the developer should have foreseen it, so it did not constitute force majeure; bad weather and government meetings did not constitute force majeure; the grace period should be strictly applied according to the contract and cannot be arbitrarily cumulative; and the default penalty standard was a true expression of the parties' intent and was not illegal. Ultimately, the court adopted the above arguments and ordered the developer to pay a default penalty of 118,366.12 yuan and litigation fees. It should be noted that if the delay is too long and accompanied by project shutdown, a claim for rescission of the contract, return of the house price, and compensation for losses may be more advantageous.

IV. Practical suggestions and legal basis

Action suggestions: 1. Review all delivery and breach-of-contract clauses in the contract and supplementary agreements; 2. Verify the gap between the agreed delivery standards and the actual situation; 3. Collect payment receipts, move-in notifications, and acceptance filing materials; 4. Commission a professional organization to conduct quality inspections and retain the reports; 5. Send a written rectification notice to the developer regarding quality and late delivery issues; 6. Calculate the breach-of-contract penalties and clarify the calculation period; 7. Assess whether the conditions for terminating the contract have been met. Legal basis: Articles 577, 582, 583, and 584 of the Civil Code of the People's Republic of China (all effective from January 1, 2021); Related provisions of the "Measures for the Administration of the Sale of Commercial Housing" (Decree No. 88 of the Ministry of Construction, promulgated and implemented on June 30, 2000).

5. Henglu Law Firm's Advice

Firstly, the delivery standards should be specified in the contract, otherwise it will be difficult to provide evidence in case of quality disputes. Secondly, the grace period clauses must be checked word by word to avoid being claimed as cumulative. Thirdly, the defense of force majeure requires considering the contract signing time and its predictability. Fourthly, for quality defects, it is recommended to first require a limited period for repair and retain written notifications. Fifthly, the threshold for claiming to withdraw from the contract is relatively high, and it is necessary to prove that it seriously affects normal living and use. Sixthly, in the case of withdrawing from the contract, the mortgage loan should be dealt with together. Seventhly, attention should be paid to the statute of limitations to avoid delays. Eighthly, the on-site images and inspection reports of the acceptance process are very important, and attention should also be paid to preserving the rectification notifications and response records.

VI. Frequently Asked Questions

Q1: If the developer fails to deliver the house on time, what amount of breach of contract damages can I claim?

According to the contract provisions, the pre-sale contract for commercial housing is usually calculated at a rate of one-tenth to five-tenths of the paid housing price per day, with some contracts stipulating a fixed amount or a tiered standard. The calculation period usually starts from the day following the expiration of the agreed delivery period or the expiration of the grace period, and ends on the actual delivery date. If the agreed standard is too high or too low, the buyer may request the court to adjust it according to law, but the adjustment range is limited.

Q2: The developer said that the pandemic is a force majeure, so can they be exempt from liability?

It depends on the time when the contract was signed. If the relevant circumstances were already normalized at the time the contract was signed and the developer should have foreseen them, they generally do not constitute force majeure. In judicial practice, for situations such as the COVID-19 pandemic, it is often required to prove the direct causal relationship with the construction progress and its unpredictability. If the developer merely claims in general that the COVID-19 pandemic caused a delay, it is usually difficult to exempt them from liability. It is recommended to require them to provide specific notifications of the suspension of work and the basis for the extension of the construction period.

Q3: If there are defects in the quality of the house, can I directly request to withdraw from the contract and get a refund?

A certain threshold must be reached. For general defects such as seepage, hollow cavities, and cracking, the developer is usually required to repair them within a specified timeframe. If the repairs are not completed within the deadline, the buyer may claim a price reduction or compensation. Only when the defects seriously affect normal living and use may they constitute a fundamental breach of contract and lead to a request for contract termination. In practice, it is recommended to first obtain a testing report and communication records, and then decide on the appropriate claim method.

Q4: If problems are found during the inspection, how can I document them most effectively?

It is recommended to adopt four methods simultaneously: taking on-site photos and panoramic photos containing time information; inviting third-party inspection agencies to issue reports; requiring developers to sign the problem list on written documents and agree on a rectification period; and keeping records of communication between owners and relevant materials from property management and supervision. Multiple materials can corroborate each other, making the evidence more convincing.

Q5: The developer has been delaying the handover of the house. Can I apply for a refund for the house?

Yes, but it requires proof of a fundamental breach of contract, such as a particularly long delay in delivery, project suspension, the developer being disqualified or losing its ability to perform the contract, etc. In practice, developers often defend themselves with an extension period, so it's necessary to check the extension period clause and the actual number of days of delay. If you decide to withdraw from the contract, you should also handle matters such as the termination of the mortgage loan, the return of the purchase price, and the loss of interest.
