Building on your house or property can be a good idea to create more space and increase the property’s value. But before you start planning your extension, it is important that you know the rules regarding building permits and exemptions that the Housing Authority has established.
An extension usually requires a building permit, but there are certain exceptions that allow you to build without applying for permission from the municipality. Here are some of the most common rules that you should keep in mind when planning your extension:
- Size: If you plan to build to less than 15 square meters, you usually do not need to apply for planning permission. This applies even if the extension does not increase the total area of the house by more than 15 square meters.
- Height: The extension must not be raised higher than the existing building. If you plan to build a higher extension than the existing house, you need to apply for planning permission.
- Location: The extension must be located at least 4.5 meters from the nearest plot boundary if it is higher than four meters. If the extension is lower than four metres, it may be placed closer to the plot boundary.
- The Planning and Building Act: It is important that you know the Planning and Building Act that regulates construction in Sweden. This law requires you to follow certain rules when you build, regardless of whether you need planning permission or not.
- Building notification: If you do not need to apply for a building permit, you still need to make a building notification to your municipality. This means that you inform the municipality about your planned extension, so that they can ensure that it complies with current rules and requirements.
Building your house or property can be an exciting and profitable investment, but it is important that you know the rules regarding building permits and exemptions. If you are unsure whether you need planning permission or not, contact your municipality for more information and guidance. Your building contractor can also assist you through the building permit process.
