Renovations, heritage and volumes
For renovation projects in Chêne-Bougeries, official building register data provides a baseline for your planning. With 1860 buildings in the registry, please note that information regarding the renovation year is unavailable, and the building volume for the 1386 houses is not measured according to SIA 416 standards. Regarding heritage status, out of 1860 buildings, only 74 are known to the registry, with no protected status recorded. Due to this partial data coverage, it is essential to contact the municipality early in your planning process to discuss project requirements, as official records may not reflect all local constraints for your home.

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.
