Subletting in Sundsvall — Rules and Tips for Tenants

If you live in Sundsvall and are considering renting out your apartment to someone else while you are away, understanding the legal framework for subletting is essential. Swedish housing law is clear: you generally need your landlord’s written consent before subletting your rental unit. This article covers the key rules, how to calculate the maximum legal rent, common pitfalls to avoid, and how major housing companies like Mitthem and private landlords handle subletting requests in 2026.

What Are the Legal Requirements for Subletting in Sundsvall?

The foundation of subletting law in Sweden is the Swedish Tenancy Act (Hyreslagen), which applies uniformly across the country, including Sundsvall. The law states that a tenant may sublet their home only with the landlord’s prior written consent. Without this permission, subletting is considered a breach of contract and can lead to termination of the lease.

How to Obtain Written Consent

To get permission, you should submit a formal written request to your landlord or housing company. The request should include:

  • The proposed subtenant’s name and contact details
  • The duration of the sublet
  • The agreed sublet rent
  • The purpose of the sublet (e.g., travel, study, work relocation)

Landlords in Sundsvall, whether private individuals or companies like Mitthem, typically evaluate these requests based on the reasonableness of the sublet and the financial stability of the subtenant.

Can a Landlord Refuse Consent?

Yes. A landlord can refuse subletting if they have a valid reason, such as concerns about the subtenant’s reliability, if the sublet is for a very short period (e.g., less than one month), or if the landlord intends to use the apartment themselves. However, the refusal must be reasonable and not arbitrary.

How Much Can You Charge for Subletting?

According to the Swedish Tenancy Act, you cannot charge a sublet rent that exceeds your own rent. This is often referred to as the "no-profit rule." You may charge exactly your monthly rent, or slightly less to account for utilities, but you cannot make a profit from the sublet.

Calculating the Maximum Sublet Rent

When calculating your sublet rent, remember to include:

  • Base rent (hyra)
  • Any additional rent for parking, storage, or amenities
  • Utility costs (avgift) if they are included in your lease

If you charge more than your total rent, you risk violating the law, and the landlord can demand the excess back or take legal action.

Common Pitfalls and How to Avoid Them

Many tenants in Sundsvall make mistakes when subletting, often due to misunderstanding the rules. Here are the most common pitfalls:

1. Subletting Without Permission

The biggest mistake is subletting without written consent. Even if you have a verbal agreement, it is not legally binding. Always get written approval.

2. Charging Excessive Rent

As mentioned, you cannot profit from subletting. Keep detailed records of your rent and any additional costs to justify your sublet price.

3. Not Informing the Landlord About Changes

If the subtenant causes damage or violates the lease terms, you remain responsible. Always keep the landlord informed of any issues during the sublet period.

How Mitthem and Private Landlords Handle Subletting in Sundsvall

Mitthem, one of the largest housing companies in Sundsvall, has a standardized process for subletting requests. They typically require a formal application, proof of income for the subtenant, and a background check. Private landlords may be more flexible but often require similar documentation.

Mitthem’s Subletting Policy

Mitthem allows subletting for up to 12 months per year, provided the tenant has lived in the apartment for at least 12 months. They also require that the subtenant is registered at the apartment to avoid issues with the municipality.

Private Landlords

Private landlords in Sundsvall may have varying policies. Some are more lenient, especially for short-term sublets (1–3 months), while others may require a higher deposit or additional guarantees from the subtenant.

Checklist for Subletting Your Apartment in Sundsvall

Before subletting, ensure you have completed the following steps:

  • Written consent from your landlord
  • Agreed sublet rent (not exceeding your own rent)
  • Signed sublet agreement with the subtenant
  • Proof of subtenant’s income and identity
  • Notification to the municipality (if required)
  • Agreement on utility costs and cleaning responsibilities

Frequently Asked Questions About Subletting in Sundsvall

Is subletting allowed without the landlord’s permission?

No. Subletting without written consent is illegal and can result in lease termination.

Can I sublet for a short period, like one month?

Yes, but you still need written consent. Short-term sublets are more likely to be refused if they are under one month.

What happens if my subtenant damages the apartment?

You are responsible for the damage. The landlord will hold you liable, and you must seek compensation from the subtenant.

Can I charge more than my rent if I include utilities?

You can include utilities in the sublet rent, but the total must not exceed your own rent plus utility costs. You cannot make a profit.

Do I need to notify the municipality about subletting?

Yes, in some cases. If the subtenant will live at the address, they must be registered with the Swedish Tax Agency (Skatteverket), and you may need to inform Sundsvall Municipality.
