Introduction
Whether you’ve recently moved to Switzerland, relocated to a new canton, or never thought much about it, understanding which spaces are considered rooms can be essential.
In Switzerland, the number of rooms in a property is calculated based on specific criteria, which may vary between cantons. This article explains these criteria. If you have any doubts—especially related to real estate transactions—consulting a professional, such as a real estate agent, is advisable to ensure that your listing or contract complies with legal standards.
What Counts as a Room in Switzerland?
In Switzerland, living rooms, bedrooms, home offices, and children’s rooms are counted as rooms. Guest rooms and studies are also included if they meet the required criteria. However, bathrooms, toilets, laundry rooms, and hallways are not considered rooms because they serve specific functional purposes.
Kitchens are generally not counted as rooms since they are considered functional spaces. However, open kitchens connected to living rooms may be counted as half rooms.
How Is a Room Defined?
The most important criterion is functionality:
- Functional spaces, such as bathrooms, toilets, kitchens, and laundry rooms, serve a specific purpose and are therefore excluded.
- Rooms are considered multi-purpose and can be used for a variety of activities, such as sleeping, working, or relaxing.
According to the Swiss Housing Evaluation System (WBS), rooms are described as neutral spaces, meaning they are not tied to a single function. The federal definition includes:
- Shared living spaces like open-plan living areas with an integrated kitchen.
- Individually used, enclosed spaces such as bedrooms and studies.
Note: Definitions may vary between cantons, making it essential to understand the local regulations in your canton of residence.
Minimum Size Requirements for a Room
Federal guidelines specify the following size requirements:
- The largest room in a property must be at least 14 m².
- All other rooms must have a minimum size of 10 m², unless cantonal rules set a lower threshold.
- The minimum ceiling height for rooms is generally between 1.80 and 2.20 meters.
Additionally, a room must be:
- Heated.
- Naturally lit and ventilated, meaning it must have a window that opens to the outdoors.
What Counts as a Half Room in Switzerland?
The term "half room" refers to spaces that do not meet the criteria for a full room. According to the federal Swiss Housing Evaluation System:
"Naturally lit and ventilated areas of at least 5 m² that cannot be classified as full rooms are considered additional spaces or half rooms."
Examples of half rooms include:
- Alcoves.
- Entryways.
- Large hallways.
- Storage rooms.
Important: While the term “half room” is commonly used, it is not an official legal classification and varies widely depending on context.
Cantonal Variations in Room Definitions
Different cantons in Switzerland apply their own rules for what counts as a room, leading to variations in how properties are classified.
Bern
In Bern, the term "studio" is used instead of "1-room apartment."
Zurich
In Zurich, rooms are counted according to Swiss standards, but the minimum size for rooms is set at 6 m².
Geneva
In Geneva, kitchens are considered rooms. This means the number of rooms in a property includes the kitchen, as defined by the cantonal law on buildings (LCI), which also specifies ventilation and size requirements.
Vaud
In Vaud, kitchens are not counted as rooms. The canton also has specific rules about minimum room sizes, including clear criteria for half rooms.
Neuchâtel
In Neuchâtel, only bedrooms and living rooms are counted as rooms.
Valais
In Valais, there are no standardized cantonal rules, meaning classifications may vary depending on the municipality.
Conclusion: What Counts as a Room in Switzerland?
Understanding how rooms are defined is essential to avoid confusion when searching for or listing properties in Switzerland. Local rules may differ, making it important to know the specific regulations in your canton.
If you are dealing with real estate transactions, it is always best to consult a professional real estate agent who understands the local requirements. They can ensure your property listing or purchase contract complies with all legal standards.
