How to sign a building application in Baden
Who signs, whether a scan is sufficient and what simplifications apply. We apply this information automatically in your dossier.
- Submission
- eBau Aargau
- Who signs
- The building owner, the landowner and the project author, on the signature sheet generated by the portal. Representation, for example by a planning office, is expressly permitted.
- Form of signature
- A scan or photo is sufficient
Since 15 December 2025, submission via the portal replaces the paper form. The signed signature sheet is uploaded; during the transition period, some municipalities still ask for a paper copy. - Small projects
- Cantonal forms on fire protection and wastewater are integrated into the portal. Heat pumps: noise protection certificate according to Cercle Bruit.
- 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 Aargau: eBau, Canton of Aargau: application documents.
