[Direct answer]This is illegal. The load-bearing walls and other main structures of a building belong to the common safety foundation of all owners. Any renovation work must not be carried out without authorization—those who violate this rule must stop the infringement, eliminate the danger, restore the original state, and compensate for the losses. The housing and urban-rural development department may also impose fines; if the circumstances endanger public safety, the penalties will be even more severe. Neighbors who discover such violations can file complaints and report them. There is no time limit for requiring the restoration of the original state, and the responsibility will not be lifted until the hidden dangers are eliminated.

1. Problem background and typical scenarios

The typical scenes of wall demolition: demolishing the load-bearing wall between the kitchen and the living room for an open kitchen; opening grooves and holes in the load-bearing wall for storage space; transforming the load-bearing wall into a wall cabinet; and homeowners who say "I make the decisions about my own walls" and decoration teams who say "We'll demolish it as long as the money is in place". Residents upstairs and downstairs feel anxious when they hear the sound of electric drills—the responsibility for structural safety is never just a matter for one household.

II. Key points of dispute

First, the legal attributes of the load-bearing structure. The main body and the load-bearing structure are common areas, and individual homeowners do not have the right to dispose of them. "One's own wall" does not mean "one can demolish it at will". Second, the standard for restoring the original state. It's not just about rebuilding it. It requires qualified design and construction units to develop plans and carry out the construction to meet the original safety requirements of the structure. Third, the chain of responsibility subjects. Owners, contractors, and property managers who knowingly turn a blind eye may all be involved in the chain of responsibility. Fourth, the administrative and criminal linkage of public safety. Those who endanger public safety may face criminal charges in addition to administrative penalties.

III. Professional analysis by Henglue Lawyers

The responsibility system for the demolition and modification of load-bearing walls is illustrated by two public cases: - In a case in Urumqi Intermediate Court of Xinjiang, Owner A demolished load-bearing walls in his apartment for decoration purposes. The upstairs neighbor sued to stop the infringement, eliminate hazards, and restore the original state. The court coordinated with the housing authority to conduct on-site inspections, confirming that the structural integrity of the shared main walls had been damaged. The court ordered Owner A to restore the original state of the house and explicitly required him to hire qualified design and construction units to develop and implement plans to meet the original structural requirements and eliminate safety hazards, with the costs borne by him. - In a case in Suzhou Industrial Park Court of Jiangsu, Owner Zhu demolished and modified some load-bearing walls, converting the secondary bedroom and dining room into two bathrooms and raising the floor by over 10 cm. The downstairs neighbor reported water leakage and claimed safety hazards. On-site inspections confirmed the illegal modifications, and after Owner Zhu restored the original state, the parties settled the dispute with compensation of 2,000 yuan. Key takeaways from these cases: 1. Liability does not disappear just because "neighbors didn’t notice" — Load-bearing structures belong to all owners, and any neighbor has the right to claim. Hazards represent ongoing infringements, making statutes of limitations largely inapplicable in such cases. 2. Restoring the original state requires professional standards — Self-repair is insufficient; qualified units must develop and implement reinforcement plans, which are far more expensive than the initial cost savings from unauthorized renovations. 3. Other derivative issues (water leakage, encroachment, functional changes) must be addressed alongside structural issues. The combination of "bathroom modification + floor elevation + wall demolition" in the Suzhou case reflects the compound nature of unauthorized renovation-related damages. 4. Legal basis: Articles 272 and 276 of the Civil Code stipulate that owners must not endanger building safety or infringe on other owners’ rights. Regulations on construction quality and interior decoration management explicitly prohibit altering main and load-bearing structures, with housing authorities empowered to order rectification and impose fines. 5. Neighborhood protection path: Report violations to property management (who have obligations to intervene and report) and housing enforcement authorities simultaneously. If property management fails to act or demolition continues, sue for cessation of infringement, restoration of the original state, and compensation, applying for evidence preservation and on-site inspections during litigation. 6. Owner reminder: Submit renovation drawings for property and housing authority review, confirm load-bearing wall locations via structural drawings, and include prohibition clauses in renovation contracts. - In Beijing, enforcement against unauthorized load-bearing wall modifications is strict, with clear reporting channels, and violators face full-scale penalties (restoration + fines + compensation).

IV. Practical suggestions and legal basis

The first step is to report the violation: Submit a written complaint to the property management and housing law enforcement departments and keep the evidence. The second step is to preserve the evidence: Take photos and videos of the renovation site and, if necessary, apply for evidence preservation and inspection. The third step is to file legal claims: Submit requests for cessation of infringement, restoration of the original state, and compensation for losses simultaneously. The fourth step is to ensure compliant renovations: Complete three preliminary steps: register the renovation drawings, confirm the structural integrity, and include non-alteration clauses in the contract. Main legal basis: Article 272 (Restrictions on the Exercise of Exclusive Rights), Article 276, and Article 288 (Neighborhood Relations) of the Civil Code of the People's Republic of China; Article 1167 (Elimination of Interference) of the Civil Code; Article 15 of the Regulations on Quality Management of Construction Projects; Article 5 of the Measures for the Management of Interior Decoration of Residential Buildings; Specific applications shall be subject to the currently effective laws and regulations.

5. Henglu Law Firm's Reminder

Bearer walls are the skeleton of the entire building, not the background wall of a specific apartment. It might be satisfying to knock down a wall, but restoring it to its original state requires rebuilding according to qualified plans. Fines and compensation are dealt with separately. Neighbors' reports are the eyes and ears of public safety, and property management's intervention is a legal obligation. No one should turn a blind eye to this.

VI. Frequently Asked Questions

Q1: Does putting it back together count as restoring it to its original state?

No. It requires the qualified unit to provide a reinforcement design plan and carry out the construction, so as to meet the original structural safety requirements.

Q2: Does the renovation team have any responsibilities?

Yes, if the contractor knows that the load-bearing structure is still under construction but still proceeds with the work, they will share liability with the owner based on their respective faults, and the contract's exemption clauses will be deemed invalid in legal disputes.

Q3: How long do I have to wait before I can request a restoration?

The structural hidden danger constitutes a continuous state of infringement, and the claim for removal of obstacles and restoration of the original state is not subject to the general statute of limitations.

Q4: Is the property management company liable if they fail to stop the behavior?

If we receive reports of failure to stop or report the incident, we will assume corresponding responsibilities within the scope of our fault.

Q5: Will I be detained if I smash a wall?

For those who seriously endanger public safety, administrative detention or even criminal prosecution may be imposed as a punishment, and fines and orders to restore the original state are the basic measures taken against them.

The above Q&A is mainly based on judicial practice in Beijing. There may be differences in the interpretation of the law in different regions. It is recommended to consult a professional lawyer based on the specific circumstances of the case.
