How to sign a building application in Sempach
Who signs, whether a scan is sufficient and what simplifications apply. We apply this information automatically in your dossier.
- Submission
- eBAGE+ (electronic building application)
- Who signs
- The building owner and the landowner (§ 188 PBG). The landowner's signature is a prerequisite for a valid application. Plans are prepared by qualified professionals (§ 188 para. 3 PBG).
- Form of signature
- A scan or photo is sufficient
Hand-signed and scanned signature sheet or qualified electronic signature (§ 56 PBV). In addition, at least one paper copy of the documents, which we prepare for you. - Small projects
- Simplified procedure with fewer enclosures for small projects. A copy of the digital land register plan is sufficient as the site plan.
- 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.
