Renting a Second-Hand Apartment Without Permission: Consequences and Rules

June 27, 2026

Renting a second-hand apartment without permission is a common scenario in today's housing market, but it carries significant risks for all parties involved. Many tenants and landlords are unaware of the legal consequences of circumventing the rules for second-hand rentals. This article aims to shed light on the regulations surrounding renting in the second hand without permission, the risks involved, and how to navigate this complex situation.

Why is Permission Required for Second-Hand Rentals?

According to Swedish law (Jordabalken, Chapter 12, Section 34), the landlord's consent is required to sublet a property. This protection is in place to ensure the landlord has control over who resides in the property and to prevent fraudulent second-hand rentals. While the landlord has the right to refuse a second-hand application for reasonable cause, they cannot deny it arbitrarily. Acceptable reasons often include illness, studies in another city, or extended stays abroad.

Consequences for the Tenant Renting Without Permission

If you, as a tenant, rent a property second-hand without the landlord's approval, you risk losing your right of possession and thus your right to stay. The contract can be invalidated, meaning you may be required to move out on short notice. Furthermore, you could be liable for damages to the original tenant (the second-hand landlord) if you have paid an unreasonably high rent or caused damage to the apartment.

Loss of Right of Possession

One of the most severe consequences is the loss of the right of possession. This right normally allows a tenant to remain in the property even after the lease expires, provided the landlord doesn't have a reasonable cause to terminate the agreement. In cases of unauthorized second-hand subletting, this protection is nullified, and the tenant may be forced to leave without compensation.

Invalid Rental Agreement

The rental agreement between you and the primary tenant can be deemed invalid if permission was not obtained. This means the contract has no legal effect, and you essentially have no legal grounds to occupy the property. It's crucial to understand that a second-hand contract without permission does not offer the same security as an approved one.

Financial Risks

In addition to the risk of having to move, you may face financial losses. If you've paid rent exceeding the original rent by more than 10-15% (depending on practice and overhead costs), you may be entitled to reclaim the difference. You could also be held liable for any damages you've caused to the property.

Consequences for the Primary Tenant (Subletter)

Even the person subletting without permission faces serious repercussions. The primary tenant can be evicted from their apartment, and the landlord may also claim damages.

Termination of the Rental Agreement

If the landlord discovers an unauthorized second-hand rental, they have the right to terminate the primary rental agreement. This applies even if the tenant is not residing in the apartment during the subletting period. Renting out in the second hand without permission is considered a breach of contract that can lead to immediate termination.

Liability for Damages

The primary tenant can be held liable for damages caused to the landlord by the unauthorized subletting. This can include costs for legal assistance, administrative fees, or other financial losses incurred by the landlord.

Landlord's Approval and the Process

To avoid problems, obtaining the landlord's approval before initiating a second-hand rental is crucial. The process is usually straightforward:

  1. Application: The primary tenant submits a written application to the landlord requesting permission for second-hand rental.
  2. Information: The application should include details about who will rent the apartment, for what period, and the reason for the subletting.
  3. Decision: The landlord evaluates the application and either grants consent or denies it with a reasonable justification.

If the landlord denies the request without reasonable cause, the tenant can appeal to the Rent Tribunal (Hyresnämnden) for review.

Resolving Situations with Unauthorized Subletting

If you find yourself in a situation where you are renting out or renting second-hand without permission, it's best to act proactively.

  • For the Tenant: Immediately contact the primary tenant and demand that permission be obtained retroactively. If this is not possible, consider moving to avoid further complications.
  • For the Primary Tenant: Apply for permission from the landlord immediately. Be honest about the situation and explain why you need to sublet. If you have already sublet without permission, apologize and explain how you intend to resolve it.

Handling the consequences of renting a second-hand apartment without permission requires prompt and honest communication.

FAQ about Second-Hand Rentals

Can I charge higher rent for a second-hand rental?

No, you generally cannot charge more rent than you yourself pay, plus any costs for utilities like electricity and internet. Charging an unreasonably high rent can lead to you being required to refund the difference and may also be grounds for termination.

What happens if I don't get the landlord's approval?

If the landlord denies permission without reasonable cause, you can apply for permission from the Rent Tribunal (Hyresnämnden). If you sublet without permission, it can lead to termination for you as the primary tenant and the subtenant having to move.

Can I sublet my student housing without permission?

Student housing is also subject to these rules. Permission is usually required, although the specific regulations may vary depending on the student housing provider. Always check with your landlord.

What is a reasonable cause for subletting?

Common reasons include studying in another city, working in another location, extended travel abroad, illness, or cohabiting with a partner. The landlord must have a reasonable cause to deny the request. Simply wanting to make money is not a reasonable cause for subletting, but it could be a reasonable cause for the landlord to deny a second-hand application if there's suspicion of this motive.

How long can I sublet for?

There is no general time limit, but the subletting must be for a fixed term and motivated by reasons such as work or study elsewhere. Longer sublets may require special reasons and approval from the landlord and potentially the Rent Tribunal. Renting out a furnished room or an entire apartment second-hand without permission is illegal if the landlord's approval has not been obtained.
