Earthquake-specific building regulations for private buildings
Earthquake damage can be avoided through earthquake-proof construction of new buildings and retrospective earthquake-proofing of existing buildings. In the absence of the state monitoring of building regulations, however, earthquake regulations are very often neglected or incorrectly implemented. Earthquake-proof construction will only improve and become systematic when the cantons and communes make the implementation of specific building regulations for earthquake safety mandatory.
Although a positive development could be observed over the last decade, only a minority of the cantons make the granting of planning permission for private new buildings subject to compliance with the SIA standards. At present the cantons in question are: Basel-Stadt, Valais, Nidwalden, Jura, Aargau, Freiburg and Lucerne (chronological order). The cantons of Vaud and Bern intend to introduce corresponding provisions.
The scope of the regulations and the stringency of compliance monitoring varies from canton to canton.

This indictor is not comparable at international level. There is no database or comparison of practices at international level in relation to earthquake-specific building regulations and the granting of planning permission.
The data were obtained through a survey of the cantonal building authorities in 2007. The surveying and updating of data prior to 2007 was carried out on the basis of direct contact between the FOEN and the cantons.
