[Direct answer]In the Beijing area, you can protect your rights from three aspects: quality, contracts, and procedures. First, at the quality level: Compare the decoration standards, supporting facilities, and planning requirements stipulated in the contract, and commission a qualified institution to conduct inspections or appraisals to fix evidence of quality issues, such as leakage, hollow walls, substandard configurations, and photos and inspection reports of unmet public facilities. Second, at the contract level: Review the provisions on decoration standards, supporting facilities, and delivery conditions in the commercial housing sales contract and supplementary agreements. If the actual delivery does not meet the contractual requirements, you can claim breach of contract liability and demand rectification, compensation for losses, or price reduction; if it constitutes a fundamental breach of contract, you can also claim to rescind the contract and return the purchase price. Third, at the procedural level: If the developer delays delivery and the quality issues are serious and cannot be rectified, you can file a complaint or report to the housing and urban-rural development department, demanding that they fulfill their supervisory duties; if necessary, you can initiate litigation to request repair, compensation, or rescission. According to the provisions of the Civil Code of the People's Republic of China (effective January 1, 2021) on breach of contract liability, the buyer has the right to request repair, replacement, price reduction, or compensation for losses. The inspection records and video materials at the time of accepting the house are important evidence. It is recommended to claim rights within the warranty period and pay attention to the warranty period and the statute of limitations for litigation.

I. Problem background and typical scenarios

The resumption of construction and delivery of unfinished buildings has become a common and complex situation in recent years, with buyers often facing the dilemma of "having a house but not meeting standards". There are four typical scenarios: first, the decoration standards and material brands of the delivered houses are significantly different from those agreed in the contract, resulting in "reduced specifications"; second, public facilities such as elevators, greening, parking spaces, and clubs are not built according to the plan; third, the houses have quality problems such as seepage, hollowing, and cracking; fourth, the delivery procedures are incomplete, making it impossible to obtain a real estate ownership certificate. With many projects in and around Beijing, buyers are often eager to receive their houses after a long wait, which makes it easy for them to overlook quality and supporting facilities issues. This makes it more difficult to protect their rights afterwards, so it's particularly important to fix evidence during the house acceptance process.

II. Key points of contention

Firstly, the identification of decoration and supporting standards, and the hierarchy of the effectiveness of publicity and contractual provisions. Secondly, whether the reduction of configurations constitutes a breach of contract or a fundamental breach of contract. Thirdly, the burden of proof and inspection and appraisal of quality issues. Fourthly, the selection criteria for rectification and repair, reduction of prices, and termination of contracts. Fifthly, claims during the warranty period and the handling of developers' delays. Sixthly, the responsibilities for overdue certificate issuance and non-compliance with delivery conditions.

III. Professional analysis by Henglue Lawyers

When handling such disputes, Henglu Law Firm typically proceeds according to the principle of "first fixing, then defining the nature of the problem, and finally choosing the legal path". First, fixing the evidence involves systematically taking photos of the house and public facilities before and after receiving the house, and commissioning professional institutions to conduct inspections and appraisals to form credible evidence. At the same time, preserving contracts, supplementary agreements, promotional materials, and planning drawings. Second, defining the nature of the problem involves determining whether the non-compliance with the contract is a general quality issue, a reduction in public facilities, or a fundamental breach of contract that prevents the achievement of the contractual purpose. Different definitions correspond to different claims. Third, choosing the legal path involves: if the problem can be resolved through rectification, claiming repair and compensation; if the defects affect the use value but do not constitute a fundamental breach of contract, claiming a reduction in the purchase price or compensation for losses; if the delivered house seriously deviates from the contract and fails to achieve the purpose of purchasing the house, claiming to rescind the contract and demanding the return of the purchase price and interest. In addition, for issues such as the failure to build public facilities according to the plan and the delay in obtaining certificates, complaints and reports can be filed with departments such as the housing and urban-rural development authority simultaneously, creating dual pressure from administrative supervision and civil claims. It should be noted that claims for repair and compensation should be raised in a timely manner to avoid being presumed to accept the current situation due to long-term use of the house, and attention should also be paid to the limitations of the warranty period and the statute of limitations for litigation.

IV. Practical suggestions and legal basis

Action suggestions: First, check the contract and the plan item by item before receiving the house, and make a written record and take photos and videos; Second, entrust a qualified institution to conduct inspections or appraisals of quality issues; Third, keep the contract, supplementary agreements, promotional materials, and planning documents as a basis for comparison; Fourth, promptly submit written requests for rectification and compensation to the developer, and keep the delivery receipts; Fifth, if there are issues such as incomplete fittings or delays in obtaining certificates, file complaints and reports to departments such as the housing and urban-rural development authorities; Sixth, assess whether it constitutes a fundamental breach of contract, and if necessary, claim to rescind the contract and return the purchase price.

5. Henglu Law Firm's Reminder

First, check the house first and record and take photos of each item. Evidence is the most important. Second, the definition of quality problems and reduction in specifications is different, and the rights of claim are also different. Third, if it can be rectified, priority should be given to claiming repair and compensation, and if necessary, claiming a price reduction. Fourth, if it constitutes a fundamental breach of contract, you can claim to terminate the contract and get a refund. Fifth, pay attention to the warranty period and the statute of limitations, and claim in time.

VI. Frequently Asked Questions

Q1: Is it a breach of contract to reduce the configuration?

It usually counts. If the contract or supplementary agreement stipulates the decoration standards, material brands, and supporting facilities, and the actual delivery is significantly lower than what was agreed upon, this constitutes a failure to perform according to the agreement and a breach of contract. The buyer can request rectification, compensation for losses, or a reduction in the purchase price. If the content of the promotional materials is specific and clear and has a significant impact on the decision to purchase, it may also be claimed as part of the contract content.

Q2: Can I return the room if the quality is not up to standard?

It is necessary to distinguish the degree of the problem. If the quality issue seriously affects normal living use, or if it still cannot meet the agreed standards after repair, resulting in the failure to achieve the purpose of the contract, the buyer may claim to rescind the contract and return the purchase price and interest; if it is a general quality defect, it is usually more appropriate to claim repair and compensation. Whether it constitutes a fundamental breach of contract needs to be judged based on the appraisal opinion and actual circumstances.

Q3: How long is the warranty period?

It varies depending on different parts. According to the "Regulations on Quality Management of Construction Projects" (implemented on January 30, 2000) and other regulations, the foundation and main structure of a building have a reasonable service life as specified in the design documents; the roof waterproofing, bathrooms with waterproofing requirements, and the anti-leakage of external walls generally last for five years; the heating and cooling systems last for two heating seasons and cooling seasons; electrical wiring, water supply and drainage pipes, equipment installation, and decoration projects last for two years. Developers should fulfill their warranty obligations within the warranty period.

Q4: Can the owner refuse to accept it?

Be cautious and make decisions based on the specific circumstances. If the house has serious quality issues, fails to meet the agreed delivery conditions, or the developer fails to provide necessary delivery documents (such as the completion and acceptance filing certificate), the buyer can refuse to accept the house and provide a written explanation of the reasons, while preserving the evidence. However, if it's just a minor defect, refusing to accept the house may be deemed as a delay in acceptance, which is unfavorable. It is recommended to decide whether to refuse to accept the house under the guidance of a lawyer.

Q5: How to join forces with other homeowners to protect their rights?

We can work together to consolidate evidence and claims. When dealing with common issues, owners can join forces to collect contracts, promotional materials, inspection records, and testing reports in a unified manner. They can elect representatives to negotiate with developers and, if necessary, file complaints or lawsuits collectively or individually. Standardizing evidence standards and claims strategies can help improve efficiency, reduce costs, and exert greater pressure in negotiations and litigation.
