With or without building permit

for a wooden chalet?

​

With an individual, a chalet is subject to common construction rights:

•   If the construction is installed for a period of less than 3 months, it is exempt from any formality

•   If the construction is installed for a period of more than 3 months and its Gross Work Area (SH OB) is less than 20 m2, a simple declaration is sufficient.

• On the other hand, if its surface is greater than 20 m2, a building permit is required.
