[Direct answer]In Beijing, it's illegal—the Beijing Municipal Housing Lease Regulations explicitly prohibit altering the internal structure of houses for subletting, and it's not allowed to sublet them in disguised forms such as by bedspaces. The per capita living area of rented houses must not be lower than the prescribed standards. If sublandlords or intermediaries knock down walls and install partition rooms for subletting, it's an illegal act, and they can be ordered to rectify the situation and fined. For tenants, subletting contracts may be invalid or partially invalid due to violations of mandatory regulations. Tenants can terminate the contract and demand the return of the deposit and remaining rent. If the partition rooms are demolished during fire inspections or after being reported by neighbors, the rental losses will be shared according to fault, rather than being left to the tenants to bear the consequences alone.

1. 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 second landlord went missing, and the tenants had difficulty getting their deposits back. These partitioned apartments are a gray area in Beijing's rental market. Behind the low prices lie three hidden dangers: non-compliance with regulations, safety concerns, and difficulties in protecting tenants' rights.

II. Key points of contention

First, the prohibitive provisions and penalties for partition renting. Second, the determination of the validity of the lease contract. Third, the sharing of losses by tenants after the partition is demolished. Fourth, the regulatory boundaries for subletting by secondary landlords.

III. Professional analysis by Henglue Lawyers

The first layer, rules and penalties: The Beijing Municipal Housing Lease Regulations impose strict requirements on rental conditions — rental units must be the original designed rooms, and it is prohibited to divide the interior structure of the house for rental or to rent out beds in disguise. 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 hazards and illegal electrical wiring, making the risks to public safety more immediate than the violations themselves. The second layer, the two sides of contract validity: If the leased house itself is legal but only has partition defects, mainstream judgments tend to hold that the contract is not necessarily invalidated as a whole, but the lease clauses involving partitioned areas are difficult to perform due to violating mandatory regulatory provisions. If the house itself is uninhabitable due to design flaws, tenants can terminate the contract and claim refunds of deposits and remaining rent. Administrative penalty documents confirming illegal partitions serve as powerful evidence for tenants to claim termination and refunds. The third layer, the account of loss sharing: If the partition is removed and the house 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 applies: If the sublandlord rents out the house knowing it is illegal, he/she bears the main responsibility; if tenants know it's a partitioned house but take advantage of the low price to move in, the court may reduce the sublandlord's liability. Evidence such as penalty documents, on-site photos, and refund records are used to claim compensation from the landlord (whether the property owner or the sublandlord). The fourth layer, the compliance line for sublandlords: Subletting requires the landlord's written consent, and the portion of the subletting period exceeding the tenant's remaining lease term is invalid. If a sublandlord sublets a partitioned room, the landlord also has the right to terminate the lease contract with him/her and require restoration to the original state. On the landlord's side, vigilance is needed: If the landlord allows sublandlords to install partitions, the administrative penalties and costs of restoration will ultimately fall on the property owner. Property inspections and contract prohibitions are self-protective measures for landlords.

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 keep the punishment documents, on-site images, and payment records in case of partition demolition. The third step is to send a written reminder for a refund and apply for arbitration or litigation if the deadline is exceeded. The fourth step is for the landlord to promptly prohibit the partition and preserve 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.

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 to divide it for renting, and it is even more strictly forbidden to allow people to live in the kitchen, bathroom, balcony, or storage room.

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

Yes. If the partition violates regulations and makes the apartment uninhabitable, the tenant can 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 stay in the apartment, 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?

Subletting with the landlord's written consent is legal, but the lease term must not exceed the remaining lease period. If the subletting involves partition walls, it is considered a violation of regulations, 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. These four steps must be completed before making the payment.
