How to sign a building application in Gerlafingen
Who signs, whether a scan is sufficient and what simplifications apply. We apply this information automatically in your dossier.
- Submission
- eBauSO (my.so.ch)
- Who signs
- The building owner, the landowner and the project author.
- Form of signature
- Paper original required
Electronic submission is optional; municipalities will be connected by the end of 2026. The signed signature sheet goes by post to the municipality; the application is not processed until then. - Small projects
- Notifications are possible via eBau. Submission on paper remains permitted.
- 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.
As of October 2026. Practice differs between municipalities; the municipality and canton are authoritative. Sources: Canton of Solothurn: questions about eBau.
