[Direct answer]In Beijing, it's illegal — the Beijing Municipal Housing Lease Regulations explicitly prohibit altering the internal structure of a house to subdivide it for rental, or disguising the subdivision of rentals through methods such as bedding arrangements. The per capita living area of the rented house must not be lower than the prescribed standard. If a second landlord or an intermediary demolishes walls and installs partition rooms for renting, it is a violation of regulations and can be ordered to rectify the situation and fined. For tenants, the lease contract for partitioned rooms may be invalid or partially invalid due to violating mandatory regulations. Tenants can terminate the contract and demand the return of the deposit and remaining rent on this basis. If the partition is demolished during a fire inspection or upon a neighbor's report, the rental losses shall be shared according to fault, rather than the tenants simply accepting the consequences.

I. Problem Background and Typical Scenarios

A three-bedroom apartment was partitioned into seven rooms, each costing 2,000 yuan, attracting young tenants who wanted to save money on rent. Three months later, the local authorities conducted a joint inspection and demolished the partitions. The sub-landlords disappeared, and the tenants had trouble getting their deposits back. These partitioned apartments are a gray area in Beijing's rental market. While they offer low prices, they pose triple risks in terms of compliance, safety, and legal protection for tenants.

II. Key points of dispute

First, the prohibitive regulations and penalties for partitioned rentals. Second, the determination of the validity of the lease contract. Third, the allocation of losses suffered by tenants after the partition is demolished. Fourth, the regulatory boundaries for subleasing by secondary landlords.

III. Professional analysis by Henglue Lawyers

Firstly, rules and penalties: The Beijing Municipal Housing Lease Regulation strictly stipulates the rental conditions—the rented housing units must be the original designed rooms, and it is prohibited to partition and rent them out, or to rent them out in the form of bed spaces. Kitchens, bathrooms, balconies, and underground storage rooms are not allowed to be rented out for human habitation. Violators will be ordered by relevant departments to rectify the violations, restore the original state within a specified time limit, and may be fined. Partitioned rooms often pose fire safety risks and illegal electrical wiring, making the public safety dimension a more direct risk than the violation itself. Secondly, the two sides of contract validity: If the leased housing itself is legal but only has partition defects, mainstream judgments tend to hold that the contract is not necessarily invalidated in its entirety, but the lease clauses involving partitioned areas are difficult to perform due to violating mandatory regulatory provisions. If the housing is rented out as a whole according to the original design but is uninhabitable due to the housing itself, tenants can terminate the contract and claim refunds of deposits and remaining rent. The administrative penalty document confirming the illegal partitioning is a powerful weapon for tenants to claim termination and refunds. Thirdly, the account of loss sharing: If the partition is removed and the housing becomes uninhabitable, tenants' losses include remaining rent, deposits, moving expenses, and even the price difference of finding another place to live—the fault-sharing logic: If the sub-landlord rents out the housing knowing it is illegal, he/she bears the main responsibility; if the tenant knows it is a partitioned room but still takes advantage of the low price to move in, the court may reduce the landlord's liability at its discretion; when claiming, use the penalty document, on-site photos, notices, and refund records as evidence to recover the deposits and remaining rent from the landlord (whether the owner or the sub-landlord). Fourthly, the compliance line for sub-landlords: Sub-leasing must have the landlord's written consent, and the part of the sub-lease exceeding the tenant's remaining lease term is invalid. If the sub-landlord sub-leases the partitioned rooms, the landlord also has the right to terminate the lease contract with him/her and require restoration to the original state—the landlord should also be vigilant: If he/she allows the sub-landlord to install partitions, the administrative penalties and the cost of restoring the original state will ultimately fall on the property rights, and property inspections and contract prohibition clauses are the landlord's self-protection measures.

IV. Practical suggestions and legal basis

The first step is to verify the original floor plan and partition marks of the house before renting, and require the landlord to provide a written document consenting to the subletting. The second step is to retain the punishment documents, on-site images, and payment records in case of partition demolition. The third step is to send a written notice demanding a refund, and apply for arbitration or file a lawsuit if the deadline is exceeded. The fourth step is for the landlord to promptly prohibit the partition and retain evidence if it is discovered. The main legal basis includes relevant provisions of the "Beijing Housing Lease Regulations", Article 8 of the "Commercial Housing Lease Management Measures", and Articles 716 and 724 of the "Civil Code of the People's Republic of China". The specific application shall be subject to the currently effective regulations.

5. Henglu Law Firm's Reminder

Three key points about partitioned rooms: Beijing has explicitly prohibited the use of partition walls and beds to divide spaces, and violators may face fines or demolition orders; the validity of contracts depends on the allocation of defects; tenants have grounds to terminate the lease and retrieve their security deposits; and legal documents can be used as powerful tools to recover losses.

VI. Frequently Asked Questions

Q1: Can the partitioned room in the living room be rented out?

No. It is expressly prohibited by the Beijing Housing Lease Regulations to alter the internal structure of a house and divide it for rental. It is also not allowed to live in the kitchen, bathroom, balcony, or storage room.

Q2: Can I get a refund for the deposit and rent if the partition is dismantled?

Yes. If the partition violates regulations and renders the apartment uninhabitable, the tenant may terminate the contract, demand the return of the deposit and the remaining rent, and claim reasonable damages.

Q3: Do tenants have to bear the losses themselves?

For those who know that the partition is illegal but still choose to move in, the court may reduce the landlord's liability, but the main fault usually lies with the landlord who is aware of the violation.

Q4: Is it legal for a sublandlord to sublet the property?

The subletting with the landlord's written consent is legal, but the term of the subletting shall not exceed the remaining lease term. If the subletting involves partitioning, it is illegal, and the landlord may terminate the contract and require the lessee to restore the original state of the property.

Q5: How to avoid falling into traps?

Verify the original floor plan, check the mortgage and seizure, obtain the homeowner's consent letter, and keep the chat records. After completing these four steps, you can then proceed to make the payment.
