A building permit grants you the right to construct, modify or change the use of a facility for projects that require approval. It is a state declaration that the project does not conflict with public law, which must be examined in the building inspection procedure. However, this only applies at the time of the decision.
Projects not requiring approval
A project is not subject to approval if it is exempt from procedures or is exempt from approval. Procedurally exempt projects are projects that are of minor relevance under building law. Projects that are not special buildings and comply with a qualified development plan, as well as the conversion of attics for residential purposes, may be exempt from approval (see "Related services" below). However, this depends on the municipality. If the local authority wishes an approval procedure to be carried out, the building project is not exempt from approval.
If the project does not require approval, you do not need to apply for a building permit. You would not be granted one.
Consequences of not having the required building permit
If you construct or modify a facility or change its use without the required building permit, the responsible lower building supervisory authority can intervene and take appropriate measures. This can go as far as ordering the removal of the facility.
