[Direct answer]In the Beijing area, the assessment should be entrusted to a housing safety appraisal or construction project quality inspection agency with the corresponding qualifications. The appraisal agency shall conduct on-site inspection and analysis of the house's tilt rate, settlement amount, crack patterns, and the safety status of the foundation and main structure, and issue an appraisal opinion to determine whether it belongs to a dangerous house, the causes and responsibilities. When asserting rights, the appraisal opinion is a key piece of evidence to determine the quality problems and losses. If it involves the quality of the house delivered by the developer or damage caused by adjacent construction, the owner may claim repair, compensation, or rescission in accordance with the Civil Code of the People's Republic of China and relevant regulations on construction project quality. Residents can first report the matter to the local housing safety management department, and the competent department shall organize or guide the appraisal.

1. Problem background and typical scenarios

The walls of the house cracked, the door frames deformed, and the floors tilted, which were suspected to be caused by foundation settlement or nearby construction; some people also bought new houses with excessive settlement, worried about the structural safety but didn't know where to start. Settlement and tilt may be due to design and construction defects, or caused by nearby foundation excavation and groundwater level changes. The causes and responsibilities are different, and the solutions are also very different.

II. Key points of contention

First, who to appoint to conduct the appraisal and what to appraise. Second, the causes of the settlement and tilt and the division of responsibilities. Third, the probative force of the appraisal opinion in litigation. Fourth, how to claim for repair costs and losses.

III. Professional analysis by Henglue Lawyers

The first layer concerns the subject and content of the appraisal: The appraisal of house safety should be conducted by qualified institutions, and the inspection items include uneven settlement, inclination rate, crack width and direction, and the safety grade of the foundation and load-bearing structure. Common conclusions include whether the house constitutes a danger, whether it affects safe use, and the cause of the problem. The second layer focuses on the causes and responsibilities: If the quality defects of the house delivered by the developer (such as improper foundation treatment or unsatisfactory construction quality) are identified, the developer may be required to repair, compensate, or rescind the contract in accordance with the provisions of the Civil Code of the People's Republic of China on sales contracts and construction project quality. If the problem is caused by construction activities of neighboring third parties (such as excavation of foundation pits, pile driving, or water pumping), the infringer may be held liable for cessation of infringement, restoration of the original state, and compensation for losses. If the problem stems from natural aging or improper use of the house, a separate assessment is required. The third layer addresses the evidentiary value of the appraisal: The appraisal opinion is an important piece of evidence in litigation, but it is not automatically accepted. The court will evaluate it comprehensively based on the appraiser's qualifications, procedures, methods, and the parties' cross-examination. Therefore, it is crucial to commission qualified and procedurally compliant institutions and require the appraiser to provide clear analysis of the causes and causal relationships. The fourth layer outlines the operational path and evidence collection: Residents can first report the problem to the local housing safety management or construction departments, which will organize safety inspections or guide the appraisal process. For litigation cases, they can apply to the court for a commissioned appraisal after filing a lawsuit to avoid challenges to unilateral appraisals. At the same time, they should preserve on-site photos, settlement observation records, repair invoices, and communication records with the developer or contractors. For cases involving construction project quality and loss assessment, they can refer to relevant provisions.Real estate transactions and construction projectsExperience with plates; the specific application shall be subject to the currently effective laws, regulations, and judicial rulings.

IV. Practical suggestions and legal basis

The first step is to ensure personal safety when detecting settlement and tilt, and if necessary, temporarily evacuate and report the situation to the competent authorities. The second step is to entrust a qualified institution or apply to the court for an appraisal to determine the cause and safety level. The third step is to identify the responsible party based on the cause, fix the scene, and collect evidence. The fourth step is to claim repair costs, temporary accommodation fees, depreciation losses, and other damages. For major structural issues, the contract may be terminated and compensation may be sought. The main legal basis includes Article 577, Article 801, and Article 1165 of the Civil Code of the People's Republic of China, the Regulations on Quality Management of Construction Projects, and the Regulations on the Management of Dangerous Houses in Cities. The specific application shall be subject to the currently effective laws, regulations, and judicial rulings.

5. Henglue Law Firm's Reminder

There are three key points in the appraisal of settlement: first, identify the problem and then discuss the responsibility; the cause and safety level are the core conclusions; the developer's quality defects and the neighbor's construction causing damage have different responsible parties and legal procedures; unilateral appraisals are easily questioned, and it is more reliable to apply to the court for an appraisal in litigation.
