Renting out your apartment in the second hand can be a good solution for both those who want to travel for a period and for those who need temporary housing. But what does a sublease actually entail, and what are the rules? This article provides a comprehensive overview of subleasing in Sweden.

What is a Sublease?

A sublease occurs when a primary tenant (the original tenant) rents out their dwelling to another person (the subtenant) while the original rental agreement with the landlord remains valid. The original tenant effectively becomes a "mediator" of the apartment. It's important to distinguish this from a situation where the original tenant moves out and a new tenant takes over the entire contract – this is not permitted without the landlord's approval.

Why Sublease?

There are several reasons why one might need or want to sublease their home:

  • Temporary stay abroad: If you plan to study, work, or be away for an extended period but wish to keep your current home.
  • Commuting for work: If you get a job in another city but want to retain your current residence.
  • Dual residence: If you have a temporary accommodation near a new workplace but want to keep your permanent home.
  • Financial reasons: Subleasing can provide extra income to cover part of your own rent.

Legal Framework and Rules for Subleasing

In Sweden, subleasing is primarily regulated by the Land Code (Jordabalken - JB), specifically the chapters concerning rental agreements. Rental laws are designed to protect tenants, and therefore, rules must be followed for a sublease to be valid and legal.

Landlord's Approval

The most crucial point to understand is that you, as the primary tenant, must always obtain the landlord's written permission to sublease your apartment. Subleasing without permission can lead to the loss of your own primary rental contract. The landlord can deny a sublease if there are valid reasons, such as suspicion that the sublease is not legitimate or that the prospective subtenant is unsuitable.

Reasons for Subleasing

While the landlord has the right to deny, they cannot do so without cause. According to Swedish law, you have the right to sublease your apartment if you have valid reasons. Common reasons that are usually accepted include:

  • Illness
  • Studies in another city
  • Temporary work in another city
  • Extended stay abroad
  • Conscription or other military service
  • Old age (if one needs to move to a retirement home but wishes to keep their current apartment)

If the landlord denies permission despite you having valid reasons, you can apply for permission from the Rent Tribunal (Hyresnämnden). The Rent Tribunal can grant you permission to sublease if you can demonstrate valid reasons and that the landlord did not have legitimate grounds for refusal.

Sublease Agreements

It is essential to draft a written sublease agreement. This contract should clearly outline the terms between you, as the primary tenant, and your subtenant. The agreement should include:

  • Parties' details: Full names and personal identification numbers/organization numbers for both you and the subtenant.
  • Apartment information: Address, apartment number, number of rooms and kitchen.
  • Rental period: Clear start and end dates for the sublease.
  • Rent: The amount of rent, including any costs for electricity, water, heating, and internet. It's important to note that you, as the primary tenant, cannot charge the subtenant a higher rent than you pay to your landlord, plus a reasonable fee for furniture and operating costs if the apartment is furnished. You are not allowed to profit from the sublease.
  • Notice period: If and how the subtenant can terminate the agreement.
  • Other terms: Rules regarding pets, smoking, furnished/unfurnished status, etc.

Templates for sublease agreements can be found online, for example, from the Tenants' Association (Hyresgästföreningen) or other housing portals. Ensure you use a legally sound contract.

Rights and Responsibilities

Both you as the primary tenant and your subtenant have rights and responsibilities.

Primary Tenant's Responsibilities:

  • Responsibility for rent: You are still obligated to pay rent to your landlord, even if the subtenant fails to pay you.
  • Responsibility for damages: You are liable for any damages caused by the subtenant in the apartment.
  • Duty to inform: You must inform the subtenant about the rules applicable to the property and the apartment.
  • Landlord's approval: You must ensure you have the landlord's permission.

Subtenant's Rights and Responsibilities:

  • Right to the dwelling: During the rental period, the subtenant has the right to live in the apartment according to the agreement.
  • Obligation to pay rent: The subtenant must pay rent to you on time.
  • Obligation to care for the dwelling: The subtenant must take good care of the apartment and adhere to the applicable rules.
  • Obligation to vacate: At the end of the agreement, the subtenant must move out.

Common Pitfalls and Considerations

  • Avoid illegal subletting: Subleasing without the landlord's permission is illegal and can lead to the loss of your primary contract. It can also mean the subtenant lacks legal protection.
  • Check your insurance: Verify if your home insurance covers subleasing. Often, an add-on insurance is required, or you need to inform your insurance company.
  • Be clear about rent: As mentioned, you cannot charge a higher rent than you pay yourself plus a reasonable fee. Profiting from the sublease can lead to problems.
  • Always write a contract: A written sublease agreement is your and the subtenant's security. Ensure it is legally correct.
  • Communication: Maintain open communication with both your landlord and your subtenant throughout the subleasing period.

Conclusion

A sublease can be a convenient solution, but it's crucial to be aware of the regulations. Always obtaining the landlord's approval, drafting a clear sublease agreement, and understanding your rights and responsibilities are key to a successful sublease. By following these guidelines, you can avoid common issues and ensure a safe and positive experience for both you and your tenant.

FAQ about Subleasing

Can I charge my subtenant more rent than I pay myself?

No, as a general rule, you cannot charge your subtenant a higher rent than you pay to your landlord. However, you may add a reasonable fee for furniture and for the operating costs incurred if you furnish the apartment. Profiting from the sublease is not permitted.

What happens if I sublease without permission?

If you sublease your apartment without obtaining the landlord's written permission, it can be considered a breach of contract. This can, in turn, lead to the loss of your primary rental contract. Furthermore, the subtenant lacks legal protection.

How long can I sublease for?

There is no general time limit for how long you can sublease, but the sublease must be temporary. If you plan to be away for an extended period, such as a year or more, specific reasons and continued approval from the landlord and possibly the Rent Tribunal may be required.

Do I need a written sublease agreement?

Yes, it is strongly recommended to always draw up a written sublease agreement. A written contract protects both you as the primary tenant and your subtenant by clearly specifying the terms of the sublease.

Can I sublease part of my apartment?

Yes, it is possible to sublease a part of your apartment, such as a room. Landlord's permission is also required in this case. The rules regarding rent and contracts also apply when subleasing individual rooms.
