Renovations, heritage and volumes

For your renovation plans in Versoix, the official building register data provides limited insights due to partial coverage. Information regarding heritage protection status and the year of renovation is not currently recorded. Furthermore, building volume data, measured under the SIA 416 standard, lacks specific median values to guide your project scale. Given the absence of these figures, it is essential to contact the municipality directly. Engaging with local authorities early is the best way to obtain the precise technical details required for planning heating or insulation works and ensuring your renovation cost estimates are accurate.

Permits

  • Competent authority : Office de l'urbanisme
  • Solar panels : Soumise à autorisation de construire, mais avec une procédure simplifiée si certaines conditions sont remplies (conformité au droit des zones, intégration paysagère et patrimoniale satisfaisante, puissance totale inférieure à 100 kVA). Procédure simplifiée possible par le biais d'une déclaration préalable, si les installations sont sur des toits en pente conformes ou sur des toits plats non visibles, ou dans certains périmètres d'aménagement (zone 4B, 5, 5A, 5B, 6).
  • Heat pump : Les pompes à chaleur air-eau ou air-air nécessitent une autorisation de construire si leur puissance dépasse 10 kW. Si elles sont installées à l'intérieur, elles sont soumises à la LCI (Loi sur les constructions et les installations) et non à la LALPT (Loi sur l'aménagement du territoire et les constructions). Pour les pompes à chaleur de puissance inférieure ou égale à 10 kW, une déclaration préalable est nécessaire, accompagnée d'une attestation de conformité acoustique. Des exigences en matière de bruit sont mentionnées pour les installations extérieures, avec des valeurs limites d'immissions fixées par l'Ordonnance sur la protection contre le bruit (OPB) et des règles spécifiques du règlement d'application de la LCI (rLCI). Un bureau spécialisé en acoustique est souvent requis pour les projets complexes.
