Lex Koller Is Being Tightened: What Newcomers and Investors on Lake Zurich Should Know Now

Lex Koller Is Being Tightened: What Newcomers and Investors on Lake Zurich Should Know Now

Some laws are barely known outside the industry and still shape a family's most important decision. Lex Koller is one of them. Since 1985 it has governed who may buy real estate in Switzerland without a Swiss passport. For four decades it was gradually relaxed. Now the Federal Council is reversing course.

On 04/15/2026 it opened the consultation on a tightening of the law. The consultation closed on 07/15/2026. The next step is the Federal Council's dispatch to Parliament. Anyone moving to Switzerland or investing here in 2027 is well advised to plan with the new rules in mind.

What applies today

The current framework is generous for most newcomers.

EU and EFTA citizens residing in Switzerland buy residential property without a permit. This includes Norwegians, since Norway is an EFTA member.

Third-country nationals, for example from the United States, the United Kingdom, Singapore or India, may also buy their primary residence without a permit once they hold a B residence permit. The condition: they live in the property themselves.

Vacation homes (subject to cantonal quotas), second homes and pure investment properties require a permit. Commercial real estate can currently be acquired freely by any person abroad.

What the Federal Council wants to change

The proposal has five core elements.

First: third-country nationals without a C settlement permit will need a permit to buy their primary residence.

Second: anyone who leaves Switzerland must sell the property within two years. The house can no longer stay in the family as a vacation home or an investment.

Third: commercial properties are brought back under Lex Koller. Persons abroad may acquire them only for their own business. Buying to lease or rent out is no longer possible.

Fourth: persons abroad will as a rule no longer be allowed to acquire listed shares in residential real estate companies or regularly traded units in real estate funds.

Fifth: cantonal quotas for vacation homes are halved and resales between foreign buyers become subject to a permit.

There is one relief: foreign-controlled hotels are to find it easier to build staff housing.

Who is affected and who is not

The proposal draws a clear line.

EU and EFTA citizens residing in Switzerland: no change for the primary residence. For Scandinavian families arriving in Zug, Wollerau or on Lake Zurich, the path to owning a home stays open.

Third-country executives holding a B permit: a new permit requirement for the primary residence and a resale obligation on departure. This concerns precisely the executive families that pharma, finance and crypto companies bring to Zug and Zurich from the United States and Asia.

Companies: a foreign-controlled company that wanted to buy housing for employees and lease it to them faces a new hurdle. Executive housing becomes even more a question of rentals and serviced apartments.

Investors and family offices: indirect access to the Swiss residential market through listed companies and funds is closing. As we read the proposal, existing positions are not affected retroactively, but only the final legal text will settle the details.

When it takes effect

None of this applies yet. The consultation is followed by the Federal Council's dispatch, deliberations in both chambers of Parliament and possibly a referendum. For contested bills, several years typically pass before entry into force.

The proposal is nevertheless relevant today. A relocation often takes six to eighteen months from decision to move-in. A house bought in 2027 may be sold in 2032. Anyone planning now is planning into the scope of the new law.

Four practical considerations

First: clarify nationality and permit status early. In binational families, it often matters whose name is on the title. An EU passport in the family can make the difference.

Second: rent first, buy later. What has been common practice among UHNWI for years (renting during the permit and tax ruling phase, buying afterwards) becomes a deliberate strategy for third-country nationals. Buying only once the C permit is in hand avoids the new permit requirement.

Third: rethink corporate solutions. Buying housing through the company becomes harder. Long-term leases, business apartments for the transition period and reliable access to rental properties in prime locations gain value.

Fourth: review commercial and investment real estate before the dispatch. Persons abroad who intend to acquire a commercial property to lease out, or units in residential real estate vehicles, should know the window.

A location that remains stable

The tightening is a response to the immigration debate, not to real estate as an asset class. The framework that draws wealthy families to Switzerland has, if anything, firmed up over the past twelve months. On 11/30/2025 Swiss voters rejected the inheritance tax initiative with 78.3 percent voting no. In Norway, the wealth tax remained in place after the September 2025 election. Demand for housing in Zug, Schwyz and on Lake Zurich remains structurally high while supply in prime locations remains scarce.

Lex Koller does not change whether families come. It changes how they live. That is exactly where advisory work begins.

This article is intended as orientation, not as legal or tax advice. The legal text and a case-by-case review by a specialized law firm are decisive.

The Swiss Real Estate Landscape in 2026: Why the Network Decides on Lake Zurich, in Zug and in Wollerau

Anyone looking for an exceptional home in Switzerland today meets a market that looks simple on paper and is demanding in practice. The numbers are clear. The good properties are not. They are rarely found where everyone is looking.

This article puts the 2026 real estate landscape in context, with a focus on the three submarkets that matter most to international families, executives and wealthy private clients: the shores of Lake Zurich, the canton of Zug and the Höfe district with Wollerau. And it explains why in this market the listing is not what makes the difference. The network behind it is.

A country without vacancies

On 09/10/2026 the Swiss Federal Statistical Office published the national vacancy rate. As of 06/01/2026, 45,493 apartments and houses stood empty across Switzerland. That is 0.93 percent of the housing stock, below one percent for the first time and declining for the sixth year in a row.

In our core regions the situation is tighter still. The canton of Zurich reports 0.52 percent. The canton of Zug reports 0.20 percent, the lowest rate in the country. In the lakeside municipalities and in the Höfe district, vacancy in prime locations is effectively zero. A villa with a lake view, a penthouse in Zug or a house with a panoramic view in Wollerau is not an offer that waits. It is an offer that gets placed.

Prices: high, stable and still rising

UBS puts price growth for owner-occupied homes in the second quarter of 2026 at 3.6 percent year over year and expects 3.5 to 4.0 percent nominal growth for the full year. The UBS Swiss Real Estate Bubble Index stands at 0.72, in the moderate range. In plain terms: not an overheated market, but a scarce one.

Price levels in our regions (averages, September 2026, RealAdvisor):

Wollerau: houses at around CHF 16,300 per square meter, median house price CHF 3.02 million, prime locations up to around CHF 34,000 per square meter.

Canton of Zug: houses at around CHF 15,500 per square meter, around CHF 18,000 in the city of Zug and around CHF 19,200 in Walchwil. The median rent for a house is around CHF 6,000 per month.

Lake Zurich: on the left shore, the top segment has caught up with the Gold Coast. New-build peak prices in Kilchberg and Thalwil reach around CHF 33,000 to 35,000 per square meter while Küsnacht on the right shore reaches up to around CHF 37,000.

These are average and peak values. In the segment we work in, the price range is wide and comparability is low. Two houses on the same street can differ by a factor of two, depending on the plot, the lake view, the year of construction and the discretion of the location. That is exactly why no portal replaces an on-site valuation.

Demand: less immigration, but the right kind

Immigration to Switzerland is declining. In the first half of 2026, net immigration stood at 29,884 people, 12.5 percent below the previous year. Anyone reading that as relief overlooks the structure: more than 80 percent of arrivals from the EU and EFTA come to work. And the companies bringing them in are disproportionately based in Zurich and Zug.

Three groups of buyers and tenants shape the prime locations:

Executives of international companies in banking, asset management, life sciences and the Crypto Valley in Zug. They arrive with a family, with time pressure and with a corporate budget for the transition period.

Wealthy private individuals and entrepreneurial families relocating their residence to Switzerland for tax or personal reasons, in recent years strikingly often from Norway. They frequently rent first and buy later.

Swiss owners who want to sell without anyone knowing. They are the quiet side of the market and the most important one.

Three submarkets, three logics

The shores of Lake Zurich are the market of lake views and representation. Kilchberg, Rüschlikon, Thalwil and Horgen on the left shore, Zollikon, Küsnacht, Erlenbach and Herrliberg on the right. Proximity to the city of Zurich and to the international schools makes it the preferred destination for families working in Zurich's financial center. Large plots are rare and new construction happens almost exclusively through replacement.

The canton of Zug is the market of companies. Around 360 life science companies, several hundred blockchain firms and a tax system that has attracted corporate headquarters for decades. Those who live in Zug often live where they work. Demand is structural, not cyclical. The 0.20 percent vacancy rate says it all.

The Höfe district with Wollerau, Freienbach and Pfäffikon is the market of tax planning. The canton of Schwyz has the lowest tax rates in German-speaking Switzerland and still offers lump-sum taxation, which the canton of Zurich has abolished. Those who move here have done the math. And they expect their advisor to have done it too.

Why the best properties are never listed

The same rule applies in all three submarkets: the higher the price, the smaller the share of properties offered publicly. Sellers in the top segment avoid sightseeing tourists, price debates in the village and photos of their living room on the internet. They sell through people they trust: the notary, the bank, the architect, the fiduciary, the broker who has been discreet before.

For buyers this means that access to the market is not a search field but a network. Those who do not have one see only what is left over.

The right partners on board

Which brings us to the core. A relocation to Switzerland consists of a dozen decisions, of which the property is only one. Residence, permit, tax ruling, Lex Koller, school, financing, notarization, transitional housing, security. Each of these questions has its own specialist. The mistake many newcomers make is not choosing the wrong broker. The mistake is searching for ten specialists individually who do not talk to each other.

We see our job as leading this network. It consists of seven types of partners:

Law firms focused on Lex Koller, residence law and tax rulings. They determine whether a purchase is permit-free and in which structure it makes sense. With the tightening of Lex Koller now underway, they are the first port of call.

Tax advisors with experience in exit questions. For families from Norway, Germany, the United Kingdom or the United States, the interplay between exit tax and the Swiss ruling is decisive and has to be settled before the move, not after.

Banks and family offices. They finance, they know their clients and they are often the first to learn of a planned relocation. A good advisor works with them, not against them.

Notaries. Notarizations run differently on Lake Zurich, in Schwyz and in Zug. A notary who knows the file shortens the path to signature by weeks.

Owners, developers and architects. They are the source of off-market supply. These relationships are built over years and through discretion, not through promises of commission.

Serviced apartment operators. The first three months decide whether a family settles in. A furnished home from day one, within walking distance of school and office, is not a side issue.

International schools, security services and concierge partners. They turn a house into a life.

What these partners must have in common is easy to state and hard to find: they respond within hours, not days. They speak the client's language. They have no conflict of interest they keep quiet about. And they maintain confidentiality even when no one is watching.

Two principles apply to every collaboration we enter. First: if we receive compensation from a partner, we disclose it to the client. Second: notaries, authorities and employees of our corporate clients receive no compensation from us, in any form.

What this means for you

If you run a company that brings executives to Switzerland: check whether your relocation partner can source real estate and whether your real estate partner understands relocation. Usually it is neither.

If you are a family or an entrepreneur relocating your residence to Switzerland: start with the law firm and the tax advisor, not with the portal. The property follows from the structure, not the other way around.

If you are an owner considering a sale: you do not have to list in order to sell. One conversation is enough.

And if you belong to one of the seven partner types and work in this region: we are building our network with care and welcome an introduction.
