[Direct answer]Simply owning a pet does not give landlords the right to change the locks and evict tenants directly. To legally reclaim the property, they must first confirm whether the lease agreement includes clauses prohibiting pet ownership or requiring prior consent, and then determine whether the tenant's actions have met the conditions for contractual or statutory termination. If the contract does not prohibit pets and the pet has not caused substantial interference, keeping the pet typically does not constitute a breach of contract. On the contrary, landlords unilaterally evicting tenants may constitute a breach of contract or even infringement. The provisions on contractual termination, statutory termination, and breach of contract liability in the Contracts Chapter of the Civil Code of the People's Republic of China (effective January 1, 2021) serve as the legal standard for such judgments. Even if the contract explicitly prohibits pets, landlords must first issue a written notice and set a reasonable deadline for rectification before terminating the contract through legal channels rather than using coercive methods such as changing locks, cutting off utilities, or removing personal belongings to evict tenants. The judgment must focus on three aspects: the contractual provisions, the severity of the breach, and the termination procedures, rather than simply determining whether eviction is permissible.

1. Problem background and typical scenarios

The watershed of pet-keeping disputes often lies in how those few lines in the lease are written. There are four common types of clauses: those explicitly prohibiting the keeping of any pets; those requiring prior written consent from the landlord for pet keeping; those making no mention of pets at all; and those where the landlord verbally agreed to pet keeping but failed to include it in the contract. Different clauses lead to vastly different outcomes. The typical timeline is as follows: After the tenant moves in and keeps a cat or dog, the pet's barking, odor, fur, or presence in public areas trigger complaints from neighbors and the property management. The landlord learns about this from the property management, during repairs, or viewings, and immediately issues a termination notice demanding immediate eviction. In some cases, the landlord directly changes the locks, cuts off water and electricity, and removes the tenant's belongings from the premises. The tenant, however, argues that the contract does not prohibit pet keeping, that the landlord knew about the pet for a long time, and that the pet did not damage the property or disturb neighbors. The tenant refuses to move out and demands continued performance of the contract. Variants include: a co-tenant keeping a pet; a sub-tenant raising a pet after the property is sub-leased; pets damaging floors or furniture leading to overlapping compensation claims; landlords withholding security deposits on the grounds of pet keeping; and landlords prematurely repossessing the property and renting it out again before the lease expires. The parties involved are not just the tenant and the landlord. Property management, neighbors, residential committees, and co-tenants may all leave records. While the dispute appears to be about pets, it essentially involves three issues: contract interpretation, the exercise of the right of termination, and the legality of eviction methods. The answers to these questions are largely hidden in the contractual provisions and related records.

II. Key points of contention

Disputes typically unfold along six main lines. First, the validity and interpretation of prohibitive clauses: whether the clauses are reasonably explained, whether they constitute standard form clauses that exclude the other party's main rights, and whether the general prohibition against keeping pets covers temporary foster care or ornamental fish. These issues must be determined based on the text and the contractual process. Second, the degree of breach of contract: whether the pet-keeping behavior meets the agreed upon conditions for termination, or whether it is so serious as to constitute a statutory ground for terminating the contract due to the failure to achieve the contractual purpose. Minor, remediable breaches typically do not automatically justify termination. Third, informed consent and implied acquiescence: whether the landlord's long-term rent collection, on-site repairs, and knowledge of the pet-keeping through conversations constitute implied consent or loss of rights, often reversing the conclusion. Fourth, the exercise of termination rights: whether contractual or statutory termination takes effect upon notice being delivered to the other party, whether a prior notice is required, whether a reasonable time limit for remedying the breach is granted, and whether the other party sues to confirm the termination within the objection period. Procedural flaws may render the termination legally untenable. Fifth, the legality of eviction methods: changing locks, cutting off water and electricity, unauthorized entry into the premises, and removing items may simultaneously constitute breaches of contract and infringements of possession, privacy, or property rights. More severe cases may lead to public security intervention, and the landlord cannot enforce termination unilaterally. Sixth, settlement of consequences: return of remaining rent and deposits, reimbursement for pet cleaning or repair costs, losses from relocation and temporary accommodation, and whether the landlord's claimed damages can be offset. Both parties' arguments typically focus on these issues: the landlord argues that the clauses are clearly written, neighbors have repeatedly complained, and sufficient time was given for removal; the tenant argues that the contract does not prohibit pets, the landlord acquiesced implicitly, the pet is harmless, and the eviction caused property losses. The adjudicator's determination typically follows this order: first reviewing the validity of the contract and clauses, then determining whether there are grounds for termination and whether they have occurred, followed by verifying the termination and eviction procedures, and finally addressing return and compensation.

III. Professional analysis by Hengluo Law Firm

Breaking down the termination of the contract into three stages: establishment, exercise, and consequences, the logical framework becomes clear. In the first stage, we determine whether the right of termination actually exists. We retrieve the original lease agreement and its clauses to verify whether there are prohibitions or requirements for consent. We then check whether the pet has caused demonstrable material harm and whether the landlord was aware of this and failed to object for a long time. If the contract does not contain prohibitions and there is no material harm, there is usually no basis for claiming termination. However, if the clauses are clear and the tenant still fails to rectify after being urged, the grounds for termination will become valid. In the second stage, we examine how to legally exercise the right of termination. According to the rules in the Civil Code of the People's Republic of China (effective January 1, 2021) regarding the effectiveness of termination notifications and the reasonable period for performance after urging, the landlord should issue a written notice in a traceable form, stating the basis, remedial measures, and a reasonable timeframe. If the tenant disputes the notice, they may request the court to confirm the validity of the termination within the statutory period. Before that, directly changing locks, cutting off water and electricity, or removing items constitutes unauthorized self-help and may itself constitute a new breach of contract and infringement. In the third stage, we consider the consequences of termination or continued performance. If termination is confirmed, the tenant should return the property, and the landlord should settle the remaining rent and deposit. Damage compensation is limited to actual losses. If termination is deemed invalid or the eviction is unlawful, the tenant may claim continued performance, restoration of access, and compensation for losses such as relocation, property damage, and temporary accommodation. Evidence should be organized into three categories: - Contractual materials (contracts, annexes, supplementary agreements, rental advertisements, signing chat records) - Evidence of pet ownership and harm (photos, property complaint records, neighbor testimonies, medical and registration certificates, repair and cleaning records) - Procedural materials (chats with the landlord during visits or rent collection, written objections, termination notifications and delivery receipts, police reports and site photos of lock changes and water/electricity cuts, inventory lists of removed items) Procedural milestones include: - Submitting written objections with evidence within the statutory period after receiving the termination notice - Reporting lock changes and water/electricity cuts to the police to preserve evidence and protect property - Seeking people's mediation or pre-litigation mediation if unsuccessful - Filing a lawsuit and requesting injunctive relief against further evictions if necessary - Submitting the three categories of evidence within the evidentiary period - Cross-examining the clauses regarding the tenant's obligations, the extent of breach, and the landlord's knowledge and consent during the trial - Including property managers or co-tenants as witnesses if necessary For reference:Index of legal services related to real estate transactions and construction projectsThe court's ruling on the possession and delivery of real estate. The court determined that the logic always revolves around one principle: the agreement takes precedence, but it is subject to fairness and procedural constraints. Private evictions are not allowed, and losses are compensated based on evidence and fault.

IV. Practical suggestions and legal basis

The main legal basis comes from the Civil Code of the People's Republic of China (effective January 1, 2021), particularly the provisions on contractual rescission, statutory rescission, standard clauses, and breach of contract liability in the Contracts Chapter, as well as the provisions on protection of personal privacy and residential privacy in the Personality Rights Chapter. Procedural and preservation provisions refer to the Civil Procedure Law of the People's Republic of China (amended on December 24, 2021 and effective January 1, 2024), while fee regulations follow the Litigation Cost Payment Measures (effective April 1, 2007). The Urban Real Estate Management Law of the People's Republic of China (amended on August 26, 2019) can be used to verify whether the lessor is a legitimate rights holder. The implementation recommendations include six key points: 1. First, gather the lease agreement, all appendices, and supplementary clauses, and verify word by word whether there are prohibited or consented clauses, especially those highlighted in bold. Avoid relying on memory for judgments. 2. The landlord should first issue a written notice with a reasonable deadline for rectification, retain the delivery receipt, and avoid changing locks or cutting off utilities on the same day. The tenant should respond in writing within the objection period, clarifying whether they agree to the termination. 3. Both parties should fix evidence of awareness: The landlord should keep records of the first time they learned about the pet keeping and explicit objections, while the tenant should preserve materials indicating tacit consent during property inspections, rent collection, or casual conversations. 4. In case of forced eviction, immediately report to the police and obtain a report receipt. Photograph and inventory all locks, meters, and items in the unit to avoid disputes over property losses. 5. Separately list settlement items: remaining rent, deposit, relocation and temporary accommodation costs, property damage, and pet-related cleaning and repairs. Attach all receipts and claim cessation of infringement while seeking continued performance. 6. For disputes involving multiple co-tenants or sub-leases, verify each party's identity and contractual counterparties. If necessary, include the original lessor or property management as third parties. The drafting of contractual provisions and procedural implementation are far more critical to the outcome than the pet itself.

5. Henglu Law Firm's Reminder

There are three points that need special attention. Firstly, don't take verbal permission as a guarantee. If the landlord said it's okay to keep pets when signing the contract, it should be included in the contract or supplementary agreement, or at least fixed in chat records. Otherwise, if both parties have different interpretations in the future, written provisions usually carry more weight. Secondly, procedures are more important than emotions. Even if the landlord is in the right, they should first issue a notice, then notify the tenant of the termination, and if necessary, file a lawsuit to confirm it. Changing the locks and cutting off water and electricity without authorization will make them go from being in the right to being passive. If the tenant encounters forced eviction, they should first ensure their personal and property safety, fix evidence, and then discuss responsibilities. It's not advisable to respond with escalating confrontation. Thirdly, knowing and not objecting can change the conclusion. If the landlord knew about the pet keeping but continued to collect rent for a long time without raising objections, they may be deemed to have implied consent or forfeited their rights, making it difficult to gain support for termination on this basis. Therefore, if there are objections, they should be raised as early as possible and in a verifiable manner. Whether you want to continue living or want to reclaim the house, keeping the provisions, notifications, deliveries, and on-site conditions in chronological order is much more effective than arguing on the spot.

VI. Frequently Asked Questions

Q1: If the contract does not prohibit keeping pets, can the landlord terminate the contract and reclaim the property on this basis?

Generally, this is not the case. Unless the contract explicitly prohibits pets or the pet causes substantial interference, keeping a pet itself does not constitute a breach of contract, let alone a statutory rescission. The Civil Code of the People's Republic of China (effective January 1, 2021) distinguishes between contractual rescission and statutory rescission. Statutory rescission generally requires that the breach of contract be so severe that the contractual purpose cannot be achieved. In rare cases, keeping a pet without causing damage or continuously disturbing neighbors may not reach this level. Exceptions include: if the pet causes substantial damage to the house, continues to disturb neighbors despite being warned to correct the situation, or if the parties have a clear and effective prohibition clause, the landlord may obtain grounds for rescission. If the landlord has been collecting rent for a long time and has never objected to the pet's presence when visiting the property, the landlord may be deemed to have impliedly consented. The conclusion depends on the contractual provisions and evidence of damage, and the landlord cannot simply evict the tenant just because the tenant keeps a pet.

Q2: Are the stairwell surveillance footage and property records sufficient to prove the illegal keeping of pets?

Whether it's enough or not depends on whether it can form a closed loop. Relying solely on a single video is often insufficient. Stairwell surveillance cameras can prove that pets frequently enter and exit, property complaint records and neighbor testimonies can demonstrate the nuisance, pet medical records, registration documents, purchase receipts, and interior photos can supplement the fact of keeping pets. Only when several sets of materials point to the same time, the same house, and the same animal can the proof be reliable. According to the review requirements for the authenticity and legality of electronic data in the Civil Procedure Law of the People's Republic of China (amended on December 24, 2021 and implemented on January 1, 2024), surveillance footage and chat records must retain the original carriers, be unedited and with time information. If necessary, apply for retrieval or verification in court.

Q3: What items are used to calculate the compensation for evicting tenants illegally?

Calculate the actual losses item by item, rather than basing the amount on emotions or demands. According to the provisions of the Civil Code of the People's Republic of China (effective January 1, 2021) regarding breach of contract liability and damages compensation, which adheres to the principle of restoring the status quo and allows for adjustment of excessive contractual penalties, obviously overly high quotes are usually difficult to obtain full support. The "Measures for the Payment of Litigation Fees" (effective April 1, 2007) stipulate that the filing fees shall be accumulated in stages according to the amount of the subject matter. When filing a lawsuit, it is necessary to clearly state the composition of the amount so that the costs can be controlled.

Q4: How long is the tenant's eviction notice period after the notice is served?

There is no standard number of days. Judging by a reasonable period, the agreement takes precedence. According to the rules of the Civil Code of the People's Republic of China (effective January 1, 2021) regarding the effectiveness of the notice of termination and the performance of obligations within a reasonable period after the reminder, the removal period should be measured based on the remaining lease term, the difficulty of finding a new place, the quantity of items, and local leasing practices. In judicial practice, the removal period ranges from several days to dozens of days, and it's generally difficult to consider it reasonable if it's as short as changing the locks on the same day. If the contract specifies the number of days for removal, it usually follows the agreement. If the lessee disputes the termination and sues to confirm the validity within the statutory period, the effective judgment shall prevail. It's more secure for the landlord to keep sufficient written notices, delivery certificates, and a reasonable period than to issue verbal orders. On the other hand, the lessee can claim that the procedure hasn't been completed and refuse to vacate the premises immediately.

Q5: Should I call the police on the day my water and electricity were cut off after the locks were changed, or should I first apply for mediation?

On the same day, report the case to the police and secure evidence first. Mediation can be initiated simultaneously, and the two processes are not conflicting. Changing locks and cutting off water and electricity not only affect living conditions but also involve property safety. Reporting the case to the police can fix the time, process, and on-site conditions, and leave a receipt for the report. Subsequently, take photos of the door locks, water and electricity meters, and items in the house one by one, and export the smart lock or access control records to avoid disputes later. Then send a written objection to the landlord, stating that the eviction was carried out without consent, demanding the restoration of access to water and electricity, and requiring prior notice and preservation of the delivery receipt for future entry. According to the provisions of the Civil Procedure Law of the People's Republic of China (amended on December 24, 2021 and implemented on January 1, 2024) on protective measures, if the situation is urgent and failure to stop the eviction will cause irreparable damage, an application for an order to stop the eviction can be made before or during the litigation.
