The 2026 Lex Koller Tightening: How the Federal Council’s New Proposals Reshape Swiss Real Estate

On April 15, 2026, the Swiss Federal Council fundamentally altered the outlook for cross-border real estate investment. In a direct bid to ease domestic housing shortages and counter the impending “No 10-million Switzerland” population initiative, the government unveiled a comprehensive draft revision to the Federal Act on the Acquisition of Real Estate by Persons Abroad (Lex Koller).

With the official public consultation period open until July 15, 2026, these proposals signal a swift return to a highly protectionist property regime.

For global asset managers, foreign executives, and local Swiss brokerages, this isn’t just incremental regulatory friction—it is a structural rewriting of market access. If passed into law, the loopholes that previously allowed international capital to passively benefit from the Swiss market’s low vacancy rates will be systematically dismantled.

1. Commercial Portfolios: The Death of Passive Leasebacks

For decades, commercial real estate (offices, manufacturing hubs, logistics centers) served as a reliable sanctuary from Lex Koller restrictions. Foreign entities and non-resident individuals could acquire corporate buildings without cantonal approval, allowing them to capture stable yields by renting the premises to third-party tenants.

The 2026 draft terminates this investment mechanism entirely.

The New Operational Mandate

Under the proposed rules, foreign nationals and legal entities headquartered abroad will be blocked from acquiring commercial buildings for pure investment purposes.

• The Own-Use Rule: An acquisition will only be exempt from authorization if the foreign buyer personally and directly operates their own business within that specific facility.

• The Two-Year Forced Divestment: If a foreign corporation scales back its presence or vacates the property, it faces a strict legal mandate to dispose of and sell the asset within two years. If it fails to do so, local authorities will trigger a forced public auction.

• Subsidiary Requirements: Companies headquartered outside of Switzerland will no longer enjoy direct exemptions; they must establish a localized Swiss subsidiary to handle any operational property purchases.

2. Capital Markets: Eliminating the Public Fund Loophole

Perhaps the most aggressive element of the 2026 revision is its expansion into highly liquid public markets. Historically, international buyers who were blocked from direct residential acquisitions simply bought shares in listed Swiss real estate companies or units in regularly traded Swiss real estate funds (such as REITs and SICAVs).

The Federal Council’s new draft closes this capital market channel completely.

|               CRIMINAL LIABILITY NOTICE                     |
+-------------------------------------------------------------+
| Under the new draft, the purchase of even a single unit     |
| in a Swiss residential property fund or listed company by a |
| person abroad will be prohibited.                           |
|                                                             |
| Stock exchange participants and brokers will face strict    |
| criminal sanctions if they execute buy orders without       |
| verifying the buyer's resident status through KYC.          |
+-------------------------------------------------------------+

Grandfathering Status: Reassuringly, the proposal does not apply retroactively. Shares and fund units lawfully held by foreign nationals before the enactment date are protected. However, those investors will be barred from increasing their holdings and cannot sell those shares directly to other non-residents.

3. Second Homes and the Holiday Quota Squeeze

The draft also sets its sights on tourist destinations. For non-residents looking to purchase luxury chalets or holiday apartments in Alpine tourist zones, the path to ownership is narrowing.

1. Quota Reduction: The historical baseline of 1,500 holiday home permits distributed annually to foreigners across tourism cantons (such as Valais, Graubünden, Vaud, and Ticino) will face a structural downward adjustment.

2. Closing the Inter-Foreigner Transfer Loophole: Since 2002, a transaction where a foreigner sold a holiday home directly to another foreigner bypassed the cantonal quota system. The 2026 draft subjects these transfers to full authorization checks once again, meaning every single cross-border transaction will now consume a slot from the canton’s reduced quota pool.

4. The Repatriation Trap for Third-Country Executives

For highly mobile international professionals living in Switzerland under a standard B residence permit, the real estate landscape is becoming a logistical risk.

Currently, non-EU/EFTA nationals holding a B permit can buy a single-family home or primary apartment for personal use without prior authorization. The 2026 draft shifts this into a mandatory permit review process. More critically, if that individual subsequently relocates out of that municipality or returns home abroad, they are legally obligated to sell the primary residence within two years. This measure is explicitly designed to eliminate disguised capital investments by temporary foreign workers.

How Swiss Agencies Can Navigate the Capital Pivot

As compliance requirements intensify and capital market loopholes tighten, Swiss brokerages and developer networks cannot afford to rely on stagnant, localized listing channels. To preserve deal flow amid these regulatory shifts, modern real estate portfolios must connect directly with verified, compliant foreign business operations and high-net-worth capital.

This is the exact operational framework powering ClubProperty.com:

• Zero Commission Overhead: Because ClubProperty functions as a completely commission-free marketplace, Swiss brokerages can expand their global reach without eroding their net transaction margins.

• Direct ERP & XML Syndication: Large-scale commercial and luxury portfolios can be mapped directly onto our international platform via automated URL and XML feed synchronization tools, guaranteeing real-time compliance updates.

• Advanced Numerical Modeling: Our platform allows cross-border entities to precisely model local cantonal tax variations, financing parameters, and true net operating income against current Swiss mortgage rates—ensuring transparent transactions that clear strict cantonal audits.
