Lodger or Subtenant: How to Tell the Difference

Lodger or subtenant? The key distinction is usually whether the person renting has independent use of the home or shares it with the tenant who holds the main lease. That can affect permission requirements, the agreement and the renter’s protection if the arrangement ends.

The terms can be confusing because the heading on an agreement does not necessarily match how the home is used in practice. This guide explains how to identify the arrangement and what to check before renting a room or letting a home.

Lodger or subtenant: what is the difference?

A lodger usually rents a room in a home while the tenant or owner who is letting it continues to live there. They commonly share facilities such as the kitchen or bathroom. A subtenant, by contrast, rents the whole home or a distinct part of it for independent use. The practical arrangement matters more than the label on the contract.

Question	Lodger	Subtenant
Does the person letting the room remain in the home?	Usually yes, living in the same home.	Often not; the subtenant uses the home independently.
What is rented?	Usually a room, with shared access to other areas.	The whole home or an area that can be used independently.
Is permission normally required?	Generally not if the main tenant stays and does not give up use of the home.	Usually yes for a rental apartment, from the landlord or the Rent Tribunal.
Security of tenure	A lodger normally has no right to an extension under the usual tenancy rules.	May arise after a longer period, subject to exceptions.

This is a summary of the main principles, not a definitive answer for every case. If the main tenant moves out and gives another person independent use of the apartment, the arrangement may be a sublet even if the agreement calls the person a lodger.

How can I tell which arrangement applies?

Start by asking who actually lives in the home and how the new occupant can use it. If the main tenant continues living there and shares everyday facilities such as the kitchen and bathroom, the arrangement is generally a lodger arrangement. If the main tenant has moved elsewhere and the new occupant can use the apartment on their own, it is more likely to be a sublet.

What does independent use mean?

Independent use means the subtenant is allowed to use the home as their own, rather than sharing its ordinary use with the person who lets it. The whole situation matters. The landlord or main tenant keeping some furniture, or visiting occasionally, does not alone determine the answer.

Consider whether the person letting the home has a room there and lives there regularly, whether you share common areas, and whether the new occupant has the home to themselves while the main tenant lives elsewhere. These practical details can help the parties describe the agreement accurately.

What should a room-rental agreement include?

A written agreement should identify the room, shared areas, rent, what is included, the rental period and notice arrangements. It is also useful to set out practical expectations about keys and cleaning. A written contract helps avoid disputes, but calling it a lodger agreement does not change the legal character of an arrangement that is actually a sublet.

If you are considering renting a room, check the rent, notice terms and your access to shared spaces before signing. Keep a copy of the agreement and records of payments. If you plan to let a room in a rental apartment, read our separate guide to planning the arrangement, writing an agreement and setting a reasonable rent.

When is permission required to sublet?

A tenant in a rental apartment will generally need the landlord’s consent or permission from the Rent Tribunal to sublet the apartment. This usually applies to temporary subletting too. Obtain permission before the sublet begins and provide information about the reason and the proposed period.

A tenant who remains in the home and lets someone rent a room normally does not need the same permission, provided they have not given up use of the home. They must still follow their tenancy agreement, avoid causing disruption and charge a reasonable rent. If the tenant effectively hands over the entire apartment, the arrangement may be an unauthorised sublet regardless of what the contract calls it.

Rules for a tenant-owned apartment differ from those for a rental apartment. Someone who wants to let a tenant-owned apartment for independent use will generally need the housing association’s consent or permission from the Rent Tribunal. Check the type of home and the terms that apply before making an agreement. Our separate guide to subletting covers applications, reasons and rental periods in more detail.

Agreements and security of tenure

Both a lodger and a subtenant should understand who their agreement is with. A subtenant has an agreement with the main tenant, not directly with the property owner. A lodger also has an agreement with the person letting the room. The main tenant remains responsible to their own landlord for matters such as paying rent and looking after the home.

Security of tenure concerns whether a renter can challenge the end of a tenancy or seek an extension under the relevant rules. A lodger normally does not have the same right to an extension as a first-hand tenant. In a rental apartment, a subtenant may acquire security of tenure after more than two consecutive years, but exceptions apply and the rules depend on the home and the arrangement. In some cases, the parties can agree to waive this protection using the required procedure.

Read the agreement carefully before signing, including the rent, dates, notice period and any terms about security of tenure. For the statutory framework, consult the Swedish Land Code’s tenancy provisions or seek advice. Simply changing the contract heading does not change how the arrangement is assessed.

Frequently asked questions

Can I be a lodger if the main tenant does not live there?

If the main tenant has moved out and you can use the home independently, the arrangement will often be treated as a sublet. Permission may then be required. How the home is actually used matters more than the label in the agreement.

Do I need permission to let a room in my rental apartment?

Generally not if you continue living in the apartment and let a room without giving up use of the home. If you move out or effectively hand over the whole apartment, the arrangement may instead count as subletting and require permission.

Does a lodger have security of tenure?

A lodger normally does not have a right to an extension under the usual security-of-tenure rules. Check the agreement and notice terms, which still affect when and how the arrangement can end.

Can an agreement called a lodger agreement count as a sublet?

Yes. If the occupant has independent use of the home, the arrangement may be treated as a sublet even if the agreement has another title. Describe the living arrangement accurately and make sure any required permission is in place.
