Carport - building permit required?

The 800.00 francs for the surveyor is quite a substantial amount. But my property was measured before the house was built. Now with the carport, I don't find it necessary.

So a building permit is often required.

The local conditions are different. We built a carport on my parents' property. For that, we needed a building permit. It was important that we maintain the distance to the neighbor's property. Therefore, we had to modify the access road somewhat.
