If necessary, we start with the Norwegian Public Roads Administration so that their views can be included in the application to the municipality. All municipalities have their own sign regulations and we have to identify whether or not the measure requires an application for dispensation.
In addition, notification must be sent out to neighbours at least 2 weeks before the application is submitted to the municipality, which in turn can spend about 3-12 weeks on its case processing. As your advisor, we take care of your role as a developer, and we recommend that you delay the production of signs until all approvals are in place.
