How to sign a building application in Interlaken
Who signs, whether a scan is sufficient and what simplifications apply. We apply this information automatically in your dossier.
- Submission
- eBau Bern (BE-Login)
- Who signs
- The building owner and the project author, or the authorised person if represented; for buildings on someone else's land, the landowner. Condominium ownership: all owners, or a power of attorney or the minutes of the owners' meeting together with the by-laws.
- Form of signature
- Paper original required
Submission via eBau has been mandatory since 1 March 2022. Many municipalities also require two copies signed in original; the application is only deemed submitted once they are received. - Small projects
- Minor building permit (Art. 27 BewD) with the written consent of all adjoining owners. Solar installations: notification via eBau with site plan and dimensioned roof plan at 1:100.
- Power of attorney
- We submit as your authorised representative. We enclose the power of attorney with the application, so we need it with your handwritten signature.
- Tenancy, condominium ownership
- Tenants need the landlord's written consent (Art. 260a CO); as landowner, the landlord also signs the application. With condominium ownership, structural changes to common parts (façade, roof, patio with exclusive right of use) generally require the consent of all condominium owners or a resolution of the owners' meeting (Art. 647d, 647e and 712g CC). The condominium regulations are decisive.
- Neighbours
- Neighbours' consent is usually voluntary but often speeds up the procedure. If boundary or building distances are not respected, it is required, depending on the canton as an easement entered in the land register.
