Real estate law in Switzerland encompasses a wide range of legal disciplines: civil law (transfer of ownership, servitudes, mortgages), administrative law (building permits, spatial planning), contract law (sale and purchase agreements, construction contracts) and tenancy law (commercial and residential leases). PBM Avocats has in-depth expertise in all facets of Swiss real estate law and advises investors, developers, private individuals and businesses from our offices in Geneva and Lausanne.
Purchase and Sale of Real Estate in Switzerland
The acquisition of real estate in Switzerland is subject to strict formal requirements. The sale contract must be executed as a notarial deed (art. 657 CC); any private agreement is merely preparatory and creates no obligation to transfer title. The buyer then becomes owner upon registration in the land register (registre foncier/Grundbuch). This registration is constitutive: without it, no transfer of real title occurs.
The due diligence process before a real estate acquisition is critical. PBM Avocats assists buyers in reviewing the title, identifying encumbrances (mortgages, easements, restrictions on use), verifying compliance with spatial planning regulations, and examining the seller's representations. We also draft and negotiate preliminary agreements (promesse de vente), option agreements and conditions precedent to ensure that your interests are fully protected before the notarised deed is signed.
Foreign nationals wishing to purchase residential property in Switzerland must comply with the Lex Koller, which restricts such acquisitions. Our lawyers advise on the scope of these restrictions and, where necessary, on obtaining the required authorisations from the cantonal authorities.
Condominium Ownership (PPE) and Co-Ownership
Condominium ownership (propriété par étages, PPE) is a widely used form of property ownership in Switzerland, governed by art. 712a et seq. CC. Each unit owner holds an exclusive right over their unit and a proportional share in the common parts (structure, roof, common areas). The PPE is governed by co-ownership regulations, which define the rights and obligations of each owner, the rules for use of common parts, and the procedures for decision-making by the assembly of co-owners.
PBM Avocats advises co-owners on the interpretation of co-ownership regulations, challenges to assembly decisions (art. 712m CC), allocation of renovation costs, special assessments and disputes concerning the management of common areas. We also assist PPE administrators and developers in drafting co-ownership regulations and structuring new developments.
Construction Law and Building Permits
Construction projects in Switzerland require compliance with multiple layers of legislation: federal (Act on Spatial Planning, Environmental Protection Act, Water Protection Act), cantonal (construction law, zoning regulations) and municipal (local development plans). Building permits are issued by the competent cantonal or municipal authority following a public notice procedure during which neighbours and interest groups may object.
PBM Avocats advises developers, landowners and neighbours in building permit procedures, representing clients in appeals against permit grants or refusals before administrative authorities and courts. We also handle construction contract disputes, including claims relating to defects (art. 367 et seq. CO), delays, cost overruns and subcontractor relationships.
Tenancy Law: Residential and Commercial Leases
Swiss tenancy law, governed by art. 253 et seq. of the Code of Obligations (CO), applies to both residential and commercial leases. Residential leases are subject to mandatory protective provisions that limit the landlord's ability to terminate the lease or increase the rent unilaterally. The reference interest rate (Referenzzinssatz), published quarterly by the Federal Housing Office, determines whether rent adjustments are permissible.
Commercial leases offer greater freedom of contract, though certain mandatory provisions still apply. PBM Avocats advises landlords and tenants in drafting, reviewing and negotiating lease agreements, representing clients before the rent conciliation authority (Commission de conciliation en matière de baux et loyers) and the civil courts in disputes relating to rent levels, lease termination, reinstatement of premises and recovery of security deposits.
Frequently Asked Questions about Real Estate Law
Does a real estate purchase in Switzerland require a notarial deed?
Yes. Under art. 657 of the Swiss Civil Code (CC), transfers of ownership of land must be made in the form of a public deed — that is, authenticated by a notary public. The notarial deed is a mandatory condition of validity of the sale contract; a mere private agreement is insufficient to transfer title. The transfer of ownership in the land register (Grundbuch/registre foncier) occurs only upon registration following the notarised deed. Costs related to the notarisation and registration typically amount to between 0.3% and 1% of the purchase price, depending on the canton.
What are the restrictions on foreign nationals purchasing property in Switzerland?
The Lex Koller (Federal Act on the Acquisition of Real Estate by Persons Abroad) restricts the ability of foreign nationals who are not residents of Switzerland to purchase real estate in Switzerland. The law applies to residential properties; commercial real estate and properties intended for professional use are generally exempt. The cantons administer the system and may grant authorisations within annual quotas, particularly for holiday homes in tourist regions. EU/EFTA nationals resident in Switzerland are generally exempt from these restrictions.
What is a PPE (propriété par étages / condominium ownership) in Switzerland?
Condominium ownership (propriété par étages, PPE), governed by art. 712a et seq. CC, is a form of co-ownership whereby each owner holds an exclusive right over a specific unit (apartment, parking space) and a share in the common parts of the building. Management of the PPE is governed by the co-ownership regulations and by decisions of the assembly of co-owners. Each co-owner contributes to common costs proportionally to their share. Disputes between co-owners — including challenges to assembly decisions, cost allocation or renovation projects — are subject to the jurisdiction of the civil courts.
What are the main obligations of a landlord under Swiss tenancy law?
Under the Code of Obligations (CO), the landlord is obliged to deliver the property in a state suitable for the intended use and to maintain it in that state throughout the lease (art. 256 CO). The landlord may not arbitrarily terminate the lease; termination is strictly regulated (art. 266 et seq. CO) and may be challenged before the rent conciliation authority. Rent increases must be notified using the official cantonal form and must be justified (e.g. reference interest rate increase, improvements). The tenant may challenge abusive rents before the competent authority.
What recourse is available against an illegal building permit refusal?
Building permits in Switzerland are issued by the cantonal or municipal authorities on the basis of cantonal construction legislation, which must comply with the Federal Act on Spatial Planning (RS 700) and the Federal Act on the Protection of the Environment. If a permit is refused, the owner may file an administrative appeal within the statutory deadline (typically 30 days) before the cantonal administrative court or authority. The administrative court then reviews the legality and appropriateness of the decision. If the cantonal remedies have been exhausted, an appeal to the Federal Supreme Court may be available on questions of federal law.
