Swiss Civil Code

¹ Build­ing works serving merely to em­bel­lish the ob­ject, im­prove its ap­pear­ance or make its use more com­fort­able or con­veni­ent may only be car­ried out with the con­sent of all the co-own­ers.

² If such works are com­mis­sioned with the con­sent of the ma­jor­ity of the co-own­ers who also rep­res­ent a ma­jor­ity share in the ob­ject, they may be car­ried out even against the wishes of a dis­sent­ing co-own­er provid­ing they do not per­man­ently im­pair the lat­ter’s right of use and en­joy­ment and the oth­er co-own­ers com­pensate him or her for the merely tem­por­ary impair­ment and as­sume his or her share of the costs.
