Buying Property in Switzerland as a Foreigner: The Lex Koller Guide

Buying Property in Switzerland as a Foreigner: The Lex Koller Guide

Are you considering buying property in Switzerland as a foreign national? Whether you are a resident, a cross-border commuter, or living abroad, navigating the Lex Koller (LFAIE) framework is essential. As experts in the Geneva real estate market, OAKS GROUP provides this overview to help you understand current regulations and the potential legislative changes under discussion for 2026.

Understanding the Lex Koller (LFAIE) and Its Stakes

The Federal Act on the Acquisition of Real Estate by Persons Abroad (LFAIE), commonly referred to as Lex Koller, was established in 1985 to limit foreign speculation and prevent excessive foreign ownership of Swiss soil [1, 4].

The law subjects the acquisition of certain residential properties by "persons abroad" to a cantonal authorization regime [5, 8]. As of early 2026, the Federal Council has initiated a consultation process to further tighten these restrictions in response to the national housing shortage, signaling a potential regulatory shift for international investors [1, 4].

Who is Considered a "Person Abroad"?

The legal definition focuses on your nationality, residence status, and where your "center of interests" lies [9, 10]:

• EU/EFTA Nationals: If you are a citizen of an EU or EFTA country and are legally and effectively domiciled in Switzerland, you are generally treated the same as Swiss citizens and can acquire property freely [8, 10].
• C Permit Holders: Holders of a Swiss C settlement permit, regardless of nationality, enjoy the same rights as Swiss citizens regarding real estate acquisition, provided the financing does not primarily originate from abroad [10].
• Third-Country Nationals (Non-EU/EFTA): Those holding a B permit can generally acquire a primary residence at their place of domicile without authorization, though strict conditions apply regarding self-occupancy [10].

The Case of Cross-Border Commuters and Investors

For those not residing in Switzerland, the regulations are significantly more restrictive [7, 9].

• Cross-Border Commuters (G Permit): You may be permitted to purchase a secondary residence in the region where you work, but not a primary residence or holiday home elsewhere [9].
• Non-Residents: Purchasing a holiday home or investment property is subject to cantonal quotas and federal authorization [7, 9]. Note that obtaining authorization is not guaranteed and is limited to specific tourist zones.
• Cantonal Variations: Application of the law is decentralized. Practices can vary significantly between cantons; for example, some regions have already tightened requirements, mandating that a buyer possess a legal, effective domicile in Switzerland before a deed of sale can be signed [4].

Perspectives on 2026 Regulatory Changes

The current legislative revision aims to address the ongoing housing shortage [4]. Proposals under consultation include limiting access to residential real estate for non-EU/EFTA nationals and potentially introducing a mandatory resale clause for those who relocate from Switzerland [4].

Given these potential changes, we recommend consulting with a notary or a specialized legal advisor before committing to any transaction to ensure your project remains compliant with current and upcoming LFAIE requirements [5, 8].

Key Takeaways

• Regulatory Pillar: The Lex Koller (LFAIE) remains the central framework governing real estate acquisitions by foreign nationals in Switzerland [5, 9].
• Status Matters: Your residence permit (B or C) and your status as a "person abroad" are the decisive factors in determining your eligibility for an acquisition without specific authorization [8, 10].
• 2026 Developments: Legislative discussions are underway to tighten access to residential property to curb demand and combat the housing crisis [1, 4].
• Local Application: Because enforcement is decentralized, always verify the specific practices of the canton where you intend to buy—Geneva authorities will be your primary point of contact for local compliance [5, 8].

Frequently Asked Questions

Can a B permit holder buy property freely?

Yes, but typically only as a primary residence where you are officially registered. The property must be used for your own residence and cannot be leased for investment purposes [10].

Does Lex Koller apply to cross-border commuters?

Generally, yes. Restrictions apply, though specific exceptions may exist for secondary residences located in the region of your workplace [9].

Why is the Federal Council proposing to tighten the Lex Koller?

The primary goal is to alleviate the persistent housing shortage in Switzerland by limiting foreign demand and reducing speculative pressure on the residential market [4, 9].
