The building permit is one of the most common questions when buying a sauna house: do you need a building permit to install one at all? The answer depends mainly on the size of the building, but the exact requirements can vary in places. This overview explains when a building permit is required in Estonia and what else is worth checking before installation.
When is a building permit not required for a sauna house?
Under the Estonian Building Code, small buildings with a footprint of up to 20m² and a height of up to 5 metres – including a sauna house serving a residential building – require neither a building permit nor a building notice. For example, our own model Sume, with a footprint of 18m², falls well within this limit and therefore does not need a building permit.
Building notice vs building permit: what’s the difference and when are they needed?
A building permit and a building notice are two different procedures: a building permit is more thorough, takes longer to process and mainly concerns larger or more complex buildings, while a building notice is a simpler notification to the local municipality that is quicker and easier to process. Which one (if any) a particular sauna house needs depends on the building’s height and other parameters, and can vary between municipalities. For most ready-made sauna houses with a footprint under 20m², either a building notice is enough or no documents need to be submitted at all, but it is always worth confirming this for your specific location with the local municipality. Usually this information can be obtained with a short call or email to the municipality’s building specialist, so this step rarely takes much time.
What else should you check before installing a sauna house?
In addition to the building permit question, it’s worth checking the restrictions in the local comprehensive plan, the minimum permitted distance from the neighbouring property and any detailed plan requirements in the area. These rules differ between municipalities, so before ordering a sauna house it makes sense to contact your local building specialist and clarify what needs to be taken into account on your property. You can read more about the general background and terms of building law (building permit, building notice, design conditions) on the Ministry of Climate’s building law page (in Estonian).

Summary
If the sauna house’s footprint is under 20m², a building permit is generally not required in Estonia, but it’s always worth checking with your municipality’s building specialist regarding a building notice and other local requirements, as the exact rules can vary. The surest way to avoid surprises is to check three things before ordering a sauna house: the building’s footprint and height, the restrictions in the local comprehensive plan, and the minimum permitted distance from the neighbouring property. Once these three points are clear, installing a sauna house is usually a quick and simple process without lengthy bureaucracy.
Frequently asked questions
Does an 18m² sauna house need a building permit?
No – since the footprint is under 20m², no building permit is needed.
Do I still need to submit a building notice?
That depends on the requirements of your local municipality. The safest option is to ask your municipality’s building specialist.
Can I install a sauna house on my property without consulting anyone?
Even if no building permit is needed, you should take into account your neighbours and the restrictions of the local comprehensive plan, such as the minimum permitted distance from the neighbouring property.
Do building permit rules also apply to a ready-made, delivered sauna house?
Yes, the requirements are the same regardless of how it is built. What matters is the sauna house’s footprint and height, not whether it is built on site or delivered ready-made. That’s why it’s worth asking the manufacturer for the exact footprint of the model when choosing, so you can give the right figures when talking to your local municipality.
