Condominium Renovation Works

Works and Renovations in a Swiss Condominium

Condominium ownership (PPE) represents a very widespread form of co-ownership in Switzerland. It combines exclusive ownership of an apartment with co-ownership of the common areas of the building. When it comes to undertaking works or renovations in this specific framework, owners face a set of complex legal rules. The distinction between private and common areas, authorisation procedures, cost allocation and rights of contestation all constitute aspects requiring thorough knowledge of Swiss law. Our law firm regularly accompanies condominium unit owners and administrators in managing these issues, to avoid conflicts and guarantee compliance with the steps taken.

The Legal Framework for Works in Condominiums under Swiss Law

The condominium ownership regime is principally governed by arts. 712a to 712t of the Swiss Civil Code (SCC). These provisions define the rights and obligations of co-owners, as well as the rules applicable to works and renovations. In addition, the administration and use regulations (RAU) specific to each condominium specify the practical management procedures.

The fundamental distinction regarding works concerns the nature of the areas affected:

  • Private areas, which are the exclusive property of each co-owner
  • Common areas, which belong to all co-owners

This distinction determines the procedure to follow for undertaking works. For common areas, decisions are made collectively at co-owner meetings, according to majority rules that vary depending on the nature of the works.

Classification of Works under Swiss Law

The SCC distinguishes several categories of works, each subject to specific decision rules:

  • Ordinary administrative acts (art. 712g para. 2 SCC): decided by simple majority
  • Necessary maintenance works (art. 712g para. 3 SCC): decided by simple majority
  • Useful repair and renovation works (art. 712g para. 3 SCC): decided by a majority of co-owners representing more than half the value of the building
  • Luxury or sumptuary works (art. 712g para. 3 SCC): requiring unanimity, unless the regulations provide otherwise

This classification is of major importance as it determines not only the majority required for approval, but also affects cost allocation and the possibilities for co-owners to contest decisions.

Authorisation Procedures and Decision-Making for Works

Carrying out works in a condominium generally involves several levels of authorisation, both within the co-ownership and with the administrative authorities.

Internal Procedures within the Co-ownership

For private areas, the owner has relative freedom of action, subject to not affecting the structure of the building or the rights of other co-owners. Certain private works nevertheless require the agreement of the co-owners' meeting, notably if they affect the external appearance of the building or the strength of the structure.

For common areas, the standard procedure includes:

  • Adding the project to the agenda of a general meeting
  • Detailed presentation of the project with estimates
  • Vote according to the majority required depending on the nature of the works
  • Recording of the decision in the minutes

Administrative Authorisations

Independently of internal procedures, many works require administrative authorisations, varying by canton:

  • A building permit, mandatory for works modifying the structure, use or external appearance of the building
  • Specific authorisations for works affecting protected elements (historic heritage)
  • Technical validations for electrical, sanitary or heating installations

Financing and Cost Allocation for Works

Financing works in a condominium is often a sensitive point, liable to generate tensions between co-owners. Swiss law establishes allocation principles that may be modified by the co-ownership regulations.

Cost Allocation Principles

For works concerning common areas, costs are generally allocated according to the co-ownership shares. However, art. 712h SCC provides for exceptions to this principle, notably if certain common areas serve co-owners unequally, or if the regulations provide for a different allocation key.

Financing Mechanisms

Several options are available to condominiums to finance works:

  • The renovation fund: regularly fed by contributions from co-owners, it anticipates future needs
  • Extraordinary capital calls: decided by the meeting for specific works
  • Bank loans contracted in the name of the co-ownership, generally requiring guarantees

Federal Supreme Court case law has repeatedly confirmed the obligation of co-owners to contribute to the costs necessary for the conservation of the building, even in the event of disagreement on the advisability of the works (BGE 130 III 441).

Dispute Management and Appeal Remedies

Despite a precise legal framework, works in condominiums frequently give rise to disputes between co-owners or with the administrator. Swiss law provides several conflict resolution mechanisms.

Contestation of Meeting Decisions

Art. 712m SCC allows any co-owner to contest meeting decisions that violate the law or the regulations. This action must be brought within one month of the contested decision. Grounds for contestation include non-compliance with notice or majority rules, exceeding the meeting's powers, unequal treatment between co-owners, and manifest abuse of rights. The Federal Supreme Court has developed nuanced case law on these matters, recognising that decisions concerning works must respect the principle of proportionality (BGE 141 III 357).

Frequently Asked Questions about Works in Condominiums

Can a co-owner oppose works voted on at a meeting?

A minority co-owner who votes against works decided by the required majority must nevertheless participate in their financing according to their co-ownership shares. They may contest the decision in court within one month if they consider it unlawful or inequitable (art. 712m para. 2 SCC). Luxury works, however, require unanimity.

Is a building permit required for works in a private area of a condominium?

Depending on the nature of the works, a permit may be required even for private areas. As a general rule, interior modifications without impact on the structure or facades do not require one. However, any work affecting common areas (facade, structure, roof) or changing the intended use of the premises requires prior authorisation.

How can significant works be financed in a condominium if the renovation fund is insufficient?

Several solutions exist: an extraordinary capital call on co-owners (decided at a meeting), recourse to collective credit contracted in the name of the community, or agreement for co-owners to individually finance their share. Cantonal banks and certain banks offer credit products adapted to condominiums.
