[Direct answer]In the Beijing area, according to the "responsibility scope", if it is a non-human-induced water leakage within the waterproofing warranty period (the warranty period for waterproofing projects is five years, starting from the date of passing the completion and acceptance inspection) - the developer shall bear the warranty responsibility according to law; if it is a leakage in the public areas of the roof outside the warranty period - it belongs to the common areas, and the housing special maintenance fund shall be used for repair. The property management company is responsible for applying for and organizing the repair, and the construction costs shall be paid from the maintenance fund, not by the property management company itself; if it is caused by the renovation of the upstairs tenants (solar energy, additional construction, and drainage diversion) - the responsible tenants shall be required to compensate; if it is caused by the property management company's negligence in maintenance (such as long-term blockage and non-cleaning of drainage outlets) and results in an expanded part of the losses - the property management company shall bear the responsibility according to its fault. In short, first identify the causes of the leakage, and then determine the responsible party.

1. Problem background and typical scenarios

During the rainy season, the ceiling of the top floor leaked and mold grew everywhere. When the owner complained to the developer, they were told "the warranty has expired", and when they complained to the property management company, they were told "we only handle daily maintenance". The owner was being passed the buck between the two parties. In fact, the responsibility for the leakage should be divided in a range, not a simple choice between two options.

II. Key points of dispute

Firstly, the division of the warranty period and the common areas. Secondly, the procedures for using the maintenance funds. Thirdly, the recovery of third-party liability. Fourthly, the organization of loss evidence and claims.

III. Professional analysis by Henglue Law Firm

The first layer involves a three-tier division of responsibility: 1. **Developer's warranty period** – The minimum warranty period for roof waterproofing and bathroom waterproofing is five years (starting from the date of completion and acceptance), during which any non-human-induced leaks are covered by the developer, who must also compensate for damage to ceilings, walls, and furniture. 2. **Owners' shared responsibility** – After the warranty period, the roof becomes a shared area for all owners. Repairs are funded through the Residential Special Maintenance Fund (procedure for applying: property management or owners submit proposals for voting or emergency use). The property management acts as the organizer and applicant. 3. **Tenants' responsibility** – Damage caused by renovations, additions, drainage rerouting, or solar panel base destruction on the upper floors or neighboring units must be repaired and compensated by the tenants. The second layer focuses on practical aspects of maintenance funds: - **Emergency use channels** can be activated for urgent situations (e.g., large-scale roof leaks endangering residents) without requiring a two-thirds majority vote. - If the property management delays applications, owners can urge action and file complaints with housing authorities. Established homeowners' associations should facilitate repairs. - Insufficient funds or unestablished funds are allocated proportionally or decided by all owners. - The principle of "repair first, apportion responsibility later" applies: Emergency measures stop leaks and damage, with subsequent liability and cost allocation. - Neglecting responsibility will only exacerbate losses. The third layer addresses loss fixation and claims: - **Evidence collection**: Photograph and video the leakage immediately, record the correlation between rainfall and leakage (rainy day logs are most convincing), document damaged property, and retain purchase receipts. - **Cause assessment**: Third-party experts' reports on leakage causes (e.g., aging waterproofing, construction defects, or tenant modifications) determine liability for litigation. - **Claim targets**: Developers during the warranty period (repair plus compensation), maintenance funds for shared areas after the warranty, personal property damages against at-fault parties (construction defects), and tenants for human-induced damage. - **Property management liability**: Delayed repairs, clogged drains causing water infiltration, and negligent maintenance. The fourth layer outlines enforcement timelines: - **First week**: Gather evidence and submit written complaints to developers and property management. - **Warranty period**: Urge repairs via written notices; self-fund repairs with receipts and expert reports. - **Post-warranty**: Push for maintenance funds and homeowners' association procedures. - **Large losses or disputed causes**: Evaluate and file lawsuits, often settling via pre-litigation letters. - **Typical cases**: Mediation rates are high due to clear liability and reasonable compensation amounts.

IV. Practical suggestions and legal basis

The first step is to identify the causes of the leakage and document the images and repair evidence; the second step is to determine whether the developer or the repair funding path is within or outside the warranty period; the third step is to claim compensation from the responsible residents for human-induced causes, and to issue written reminders and complaints against the property management company for delays; the fourth step is to commission an appraisal to determine the causes of the disputes and initiate litigation for compensation. The main legal basis: Article 40 of the "Regulations on Quality Management of Construction Projects" (5-year waterproofing warranty), Articles 18 to 22 of the "Measures for the Management of Special Maintenance Funds for Residential Buildings", and Articles 273 and 1165 of the "Civil Code"; the specific application shall be subject to the currently effective regulations.

VI. Frequently Asked Questions

Q1: When does the waterproof warranty period start?

The warranty period for new houses starts from the date of the project's completion and acceptance, not from the date of handover or occupancy; for second-hand houses, the remaining warranty period is calculated based on the original starting point.

Q2: The property management company says they don't have the money to make repairs. What should I do?

The maintenance funds for the common areas are used for repairs, and in emergency situations, they can be applied for emergency use. If the property management company delays the maintenance, you can file a complaint with the housing management department or have the homeowners' committee take action. The fees will not be borne by the property management company itself.

Q3: How to compensate for the water leakage caused by the renovation on the upper floor?

The renovation residents shall bear the repair costs and compensation for property losses, and claim them after the cause of the damage is identified; and the disputes over neighborly relations that are refused to be compensated shall be resolved through litigation.

Q4: Who should I hold responsible for the furniture being damaged by the water leakage?

According to the cause of the problem: if it occurs during the warranty period, the developer should be held responsible; if it's a maintenance issue with the common areas, the repair funds and the responsibility should be shared according to the fault; if it's caused by human factors, the responsible resident should be held accountable.

Q5: Who will bear the cost of the causality identification?

First, the applicant pays in advance, and the losing party or the party at fault shall bear the cost in accordance with the proportion of responsibility; the appraisal cost of the group leakage can be apportioned among all the buildings in the complex.
