Can Foreigners Buy Property in Switzerland?

You have found your apartment. The building is in a quiet street in Zurich's Seefeld district, the commute to the bank is 12 minutes, and you have been renting in Switzerland long enough to know exactly what you want. Then comes the question nobody warned you about: are you actually allowed to buy?

Switzerland is one of the few countries in the developed world where the answer to that question is not simply yes or no. It depends entirely on your nationality, your permit type, and what you intend to do with the property. Get it wrong and the transaction is legally void — the notary cannot register the transfer and you lose your deposit. The controlling legislation is called the Lex Koller, and understanding it before you make an offer is not optional.

What Is the Lex Koller?

The Bundesgesetz über den Erwerb von Grundstücken durch Personen im Ausland — universally known as the Lex Koller — has been in force since January 1985. It was designed with one explicit objective: to prevent the "over-foreignization" of Swiss soil by speculative foreign capital. The law defines certain foreign nationals as "persons abroad" and subjects any residential real estate purchase they attempt to strict administrative authorization at the cantonal level.

Without the required cantonal authorization, a purchase is null and void from inception. The deed cannot be inscribed in the Land Register (Grundbuch), and if someone proceeds anyway, the authorities can reverse the transaction and impose criminal penalties including imprisonment for deliberate fraud.

The Lex Koller applies to residential property. Commercial real estate — a property used as a genuine place of business — is generally exempt. But apartments, single-family homes, and holiday chalets are squarely within its scope.

The Permit Matrix: Who Can Buy What

Your eligibility is determined by the intersection of three factors: your nationality, your Swiss residence permit, and what you plan to do with the property.

C Permit Holders — Unrestricted

If you hold a valid Swiss settlement permit (C permit), you are fully exempt from Lex Koller restrictions regardless of nationality. A US citizen with a C permit and a German national with a C permit are treated identically to Swiss citizens. You can buy a primary residence, a holiday chalet in Graubünden, or a rental investment property anywhere in the confederation without requiring cantonal authorization.

The C permit generally requires five to ten years of continuous residence depending on your nationality and the bilateral treaties in force. EU/EFTA nationals typically qualify after five years; citizens of countries like the United States or India typically need ten years. Once you have it, the property market opens fully.

EU and EFTA B Permit Holders — Unrestricted

Citizens of EU and EFTA member states residing in Switzerland on a B permit (standard temporary residence permit) are completely exempt from Lex Koller. The bilateral Agreement on the Free Movement of Persons grants them the same property rights as Swiss citizens. A French national on a B permit can buy investment properties, rent out apartments, and purchase ski chalets without any cantonal permit. UK nationals who were resident in Switzerland before Brexit retain this status under the Agreement on Acquired Citizens' Rights.

This is the single most misunderstood point on expat forums. EU nationals on a B permit often assume they face restrictions. They do not.

Non-EU/EFTA B Permit Holders — Restricted to Primary Residence Only

This is where the rules become genuinely restrictive. If you are a citizen of a third country — the United States, the United Kingdom (new arrivals post-Brexit), India, Australia, Canada, or any other non-EU/EFTA nation — and you hold a B permit, you are classified as a "person abroad" under Lex Koller.

You may purchase exactly one property, and only under these conditions:

• It must serve exclusively as your primary residence
• It must be located in the municipality where you are legally domiciled
• You must occupy it yourself — renting it out, even temporarily on Airbnb, is prohibited
• You cannot purchase investment properties, multi-family buildings, or holiday homes in other cantons

The canton will issue authorization only after confirming these conditions are met. If you later move out of the property or attempt to rent it, you retroactively trigger a permit violation with serious legal consequences.

The most common anxiety on expat forums concerns job transfers: "What happens if my employer moves me to London?" Under current law, enforcement of the "must self-occupy" rule has been inconsistent. But proposed Lex Koller reforms opened for consultation in April 2026 would introduce a formal obligation to sell the property within two years of permanently leaving Switzerland. If enacted, this removes any ambiguity — you own it as long as you live there, and you sell when you leave.

G Permit Holders (Cross-Border Commuters) — Geographically Limited

EU/EFTA nationals holding a G permit live outside Switzerland but commute to work. Because their legal domicile remains abroad, they are classified as persons abroad for Lex Koller purposes.

They may purchase a secondary residence in Switzerland without authorization only if the property is in the specific work region, is strictly owner-occupied, and the plot does not exceed 1,000 m². Purchasing anywhere outside the work zone, or for investment purposes, requires formal authorization and is rarely granted.

Non-Residents — Holiday Homes Only, and Only in Quota Zones

Individuals without a Swiss residence permit are categorically barred from purchasing primary residences or investment properties. Their only entry point is the holiday home quota system: the federal government issues exactly 1,500 Lex Koller permits per year for non-resident foreign buyers, allocated exclusively to cantons with designated tourist zones.

Valais (roughly 330 permits annually), Graubünden, Vaud, and Bern receive the largest allocations. Zurich, Geneva, Basel, and Zug have zero quota — non-residents cannot purchase residential property in these cantons under any circumstances. Properties eligible under the quota are further limited to a net living area of 200 m² on a plot no larger than 1,000 m².

Compounding the scarcity: the Lex Weber (Second Home Initiative) prohibits new holiday home construction in any municipality where secondary residences already exceed 20% of the housing stock. Most established ski resorts in Valais and Graubünden passed that threshold years ago, so foreign buyers compete exclusively for resale inventory within the quota.

The Corporate Structure Loophole That Does Not Exist

A common question: can you buy through a Swiss company to sidestep Lex Koller? No. The law applies a "look-through" provision. A Swiss AG or GmbH is treated as a "person abroad" if foreign non-residents control more than one-third of the capital or voting rights, or provide significant financial backing. Offshore trusts, foundations, and holding structures face identical restrictions to the individuals controlling them.

Attempting to circumvent Lex Koller through a corporate structure constitutes a federal criminal offense.

Due Diligence Before You Make an Offer

If your permit situation places you in a restricted category, the most important thing you can do is make any purchase agreement explicitly contingent on receiving Lex Koller authorization. This protective clause must be in the preliminary contract (Vorvertrag). Without it, if the canton denies the permit, you forfeit your deposit.

The cantonal authorization process takes four to eight weeks. During that window, the property is off the market for other buyers, so sellers will negotiate the contingency clause, but they need to see it from the start.

If you are navigating the Lex Koller rules and figuring out whether your specific situation allows you to buy, the full step-by-step process — from permit validation through to Grundbuch inscription — is covered in the Buying Property in Switzerland — Expat Guide. It includes the affordability stress test calculations, the cantonal tax comparison across every major canton, and the Pillar 2 pension decision framework that most buyers only discover after they have already made an offer.

Practical Summary by Permit Type

The Legislative Direction of Travel

The April 2026 Federal Council consultation proposing Lex Koller tightening is significant context for any third-country national considering a Swiss purchase. The proposals include requiring formal cantonal permits for all B permit purchases (currently exempt for primary residences), mandatory sale upon departure, and restrictions on purchasing shares in listed Swiss real estate companies. None of these proposals are enacted law yet, but the direction of travel is toward greater restriction, not liberalization.

If you are a non-EU national on a B permit who has been considering buying for a few years, the time to get proper legal clarity on your situation is now — not after the rules change.
