- Submission
- Electronic building application (Bauinspektorat)
- Who signs
- The applicant, the project author and the landowner, or an authorised person. If represented, the power of attorney must be enclosed.
- Form of signature
- Paper original required
Two sets of plans and the release receipt with original signatures go by post to the Bauinspektorat. Reinach has its own Bauinspektorat. - Small projects
- Applications for small structures (§ 92 RBV) are examined by the municipality. 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.
