[Direct answer]It can be prevented. According to Article 279 of the Civil Code of the People's Republic of China (effective January 1, 2021), if an owner converts a residential property into a commercial one, in addition to complying with laws and regulations and management rules, they must obtain the unanimous consent of owners with a vested interest—that is, owners of the same building or neighbors who can prove that their interests have been affected all have the right to veto. If the owner operates the business without consent, the owners with a vested interest may request removal of the obstacle, restoration of the original state, and compensation for losses. Moreover, most residential management rules explicitly prohibit "residential-to-commercial conversions", and B&B operations also require obtaining relevant licenses. Therefore, legally speaking, the door to converting a residential property into a B&B is already very narrow.

I. Problem background and typical scenarios

The house next door was listed on a short-term rental platform. Daily guests came and went, making noise late at night, and the elevator was filled with luggage boxes. After the pandemic, urban homestays flooded into residential communities, and disputes increased accordingly. The owners' demands are simple: I bought a quiet and safe residential property, not a hotel corridor.

II. Key points of contention

Firstly, the scope of owners with vested interests and the determination of unanimous consent. Secondly, the effectiveness of the prohibitive clauses in the management regulations. Thirdly, business qualifications and regulatory requirements such as fire safety and hygiene. Fourthly, the burden of proof for damages, and how to quantify noise, safety, and depreciation in value.

III. Professional analysis by Henglue Law Firm

The defense and offense in disputes over residential conversion to commercial use are structured in three layers: "consent rules - compliance thresholds - remedial pathways". **First layer**: Consent rules serve as the core gatekeeper. Article 279 of the Civil Code stipulates that "unanimous consent of owners with a vested interest" is a prerequisite for residential conversion to commercial use. These owners typically include residents of the same building, as well as owners outside the building who can prove that their property values or living quality have been directly affected. "Unanimous consent" implies a veto right: if even one neighbor in a WeChat group explicitly objects, the conversion will lack legal validity. Evidence of consent (written confirmation) must be provided by the conversion operator. Failure to present such documentation renders the conversion illegal. **Second layer**: Compliance thresholds overlap. Most community management regulations explicitly prohibit converting residential units into commercial spaces. Violating these regulations also breaches property service contracts, and property management has the right to intervene. Short-term rental operations also face regulatory hurdles such as business licenses, special industry permits, fire safety inspections, and health permits. Urban residences typically fail to meet structural, evacuation, or registration requirements, leaving authorities free to issue rectification orders and penalties at any time. Even if neighbors tolerate the operation, regulatory compliance remains impossible. **Third layer**: Remedial pathways organization: 1. **Evidence collection**: Platform listing records, footage of guest traffic, noise level measurements, abnormal electricity and gas usage records, and property communication/complaint records. 2. **Written negotiations**: Send objections to conversion operators and platforms; enforce community regulations and file complaints with local police, market supervision, and housing authorities for unlicensed operations and residential conversion violations. 3. **Legal action**: Claim cessation of operations and restoration of residential use under Article 279 of the Civil Code and neighboring rights rules. Seek compensation for losses (rent reduction, repair costs). For serious violations involving hotel industry management, administrative and criminal liabilities (unlicensed hotel operations) may also apply. **Reverse warning to conversion operators**: To operate short-term rentals within legal frameworks, they must pass three hurdles: - Management regulations permit conversion - Written consent from vested-interest owners - Compliance with licensing requirements Failure to meet these criteria exposes every penny invested in renovation and platform operations to legal risks. Beijing has tightened urban homestay regulations, leaving limited compliance space for residential conversion to commercial use in core areas, with high risk of litigation failure in disputes.

IV. Practical suggestions and legal basis

The first step is to establish the evidence chain for the operation of the guesthouse: platform pages, footage of guests, noise detection, and property records. The second step is to send written objections to the business owners, property owners, and homeowners' associations. The third step is to report unlicensed operations and violations of residential-to-commercial conversion to local regulatory authorities. The fourth step is to file a lawsuit for removal of obstacles and compensation if no agreement can be reached. The main legal basis includes: Article 279 and Article 288 of the Civil Code of the People's Republic of China (effective from January 1, 2021); the provisions on social life noise in the Noise Pollution Prevention and Control Law of the People's Republic of China (effective from June 5, 2022); and relevant regulations on public security management in the hotel industry. Specific applications shall be subject to the currently effective provisions.

VI. Frequently Asked Questions

Q1: Which neighbors are considered "owners with a vested interest"?

In principle, all owners in this building belong to it. Owners outside the building who can prove that the value of their homes or the quality of their lives have been clearly affected can also claim a vested interest. The operator needs to obtain the unanimous written consent of all owners with a vested interest.

Q2: What should I do if the property management company doesn't care about the problem?

We shall claim the implementation of the bylaws from the property management committee, and at the same time, report the unlicensed operation and the violation of converting residential buildings into commercial ones to the local housing and urban-rural development bureau, the market supervision authority, and the police station. If the property management company fails to fulfill its duties, we can also claim its breach of contract liability at the same time.

Q3: How much does it cost to protect one's rights?

Reporting and complaints are free of charge. Lawsuits are charged on a per-case or per-object basis, and the costs of noise detection and notarization are calculated separately. The litigation costs of cases involving removal of obstacles are relatively limited, and the cost-effectiveness of reporting first and then suing is the highest.

Q4: Can I still stay in the entire building if it's all a guesthouse?

We will review each household to determine whether they have obtained the unanimous consent of the owners with relevant interests and the necessary business licenses. For those that do not comply with the regulations, we will jointly report and file lawsuits with multiple owners to safeguard their rights collectively. This approach offers clear advantages in terms of evidence collection and cost sharing.

Q5: If the renovation of the B&B is blocked, who should I contact for compensation for the renovation losses?

At one's own risk. Any investment made without legal consent or authorization is at one's own risk. Decoration losses, platform breach-of-contract penalties, etc. cannot be transferred to the opposing neighbors or property management companies. Compliance in advance is the only way to minimize losses.
