July 3, 2026

Renting out a property in the second-hand market without the landlord's explicit permission is a common situation in today's housing market, but it can also lead to unexpected and serious consequences for all parties involved. Many tenants find themselves in this situation due to ignorance or desperation, while some landlords might see it as a shortcut to extra income. But what does the law actually say about renting out or renting second-hand without approval from the original landlord or the housing cooperative?

This article aims to shed light on the legal aspects of second-hand rentals without permission. We will explore the rights and obligations of the primary tenant, the secondary tenant (subtenant), and the original landlord. Understanding these rules is crucial to avoid costly mistakes and legal disputes.

What Does Renting Second-Hand Without Permission Entail?

Renting out one's home in the second-hand market means that the primary tenant, who has a rental agreement with the property owner, sublets the property to another person (the subtenant) for a fee. According to Swedish rental law, primarily Chapter 12 of the Land Code (JB), landlord approval is normally required for second-hand rentals. This also applies to housing cooperatives (bostadsrätter), where the board typically needs to grant its approval.

When we talk about renting second-hand without permission, we refer to situations where this necessary review and approval process has not occurred. This could involve the primary tenant renting out without informing or getting approval from the landlord, or the subtenant moving in without knowing that permission is lacking.

Why is Permission Important?

The landlord's or housing cooperative's approval is not just a formality. It is a safeguard that ensures the property is not misused, rent is paid, and the person living in the apartment is suitable. The landlord has a responsibility for the property and for ensuring that the rules are followed. Renting out without permission can be considered a breach of contract by the primary tenant.

Consequences for the Primary Tenant

If a tenant rents out their property second-hand without the necessary permission, they are violating their own rental agreement. The consequences can be severe and include:

  • Termination of the rental agreement: The landlord may have the right to terminate the primary rental agreement prematurely. This means the original tenant must move out.
  • Liability for damages: If the subtenant causes damage to the apartment, or if the landlord suffers other losses due to the unauthorized subletting, the primary tenant may be liable for damages.
  • Forfeiture of tenancy: In particularly serious cases, or for repeated violations, the right to tenancy can be forfeited, meaning the agreement terminates immediately.

It is important to note that even if the landlord does not immediately terminate the agreement, an unauthorized second-hand rental can be grounds for termination if it continues for an extended period or if there are other aggravating circumstances.

Consequences for the Subtenant

The subtenant also faces significant risks when renting a property second-hand without permission. Even if the subtenant acted in good faith and paid rent to the primary tenant, they have no legal protection in relation to the original landlord.

  • Immediate eviction: If the landlord discovers the unauthorized rental, they can demand that the subtenant move out immediately. The subtenant has no right of possession against the landlord.
  • Loss of rent and deposit paid: There is no guarantee that the subtenant will get back rent or deposits paid if the rental is discovered and terminated.
  • Difficulty finding new housing: An eviction can hinder future opportunities to find new housing, as it may be registered with credit reporting agencies or with the enforcement authority (kronofogden).

Entering into a rental agreement with someone who does not have the right to sublet is a risky business. It is therefore of utmost importance to always ensure that second-hand rentals are made with the explicit approval of the landlord or housing cooperative.

The Landlord's Role and Responsibility

The landlord has the right to refuse a second-hand rental if there are grounds for it. Common reasons may include the intended subtenant not being deemed suitable, the rent charged being unreasonably high, or other circumstances that prevent approval. However, the landlord cannot unreasonably deny a rental if there is a valid reason, such as the tenant needing to sublet due to temporary work elsewhere, illness, or similar circumstances.

If the landlord discovers that a tenant is subletting without permission, they have an obligation to act. This may involve first sending a notice to the tenant to cease the subletting, and if this does not happen, proceeding with the termination of the rental agreement.

How to Avoid Problems

The best way to avoid problems with second-hand rentals is to follow the rules. If you, as the primary tenant, wish to rent out your property second-hand, you must apply for permission from your landlord or housing cooperative. Clearly state who you wish to rent to, for what period, and at what rent.

If you, as a potential subtenant, are offered a second-hand rental, ensure that the primary tenant can provide written approval from the landlord or housing cooperative. Also, check that the rental agreement you sign with the primary tenant is clear and that the rent is not unreasonably high.

Subletting without Approval – A Risky Business

Willfully or unknowingly entering into an agreement to rent second-hand without permission can have far-reaching negative consequences. Both the person subletting and the person renting in risk losing their housing and suffering financial losses. It is always better to follow the legal path and obtain the necessary approvals before subletting or renting a property second-hand.

Consequences of Renting Without Permission

The consequences of renting without permission can be significant. For the primary tenant, it can lead to the termination of the rental contract, while the subtenant risks eviction without the right to compensation. It is a situation no party wants to be in.

Landlord's Approval for Second-Hand Rental

Obtaining the landlord's approval for second-hand rental is a critical part of the process. Without this approval, the rental is illegal, and the risks are high. Always ensure this is documented.
