The Local Property Market

The property market in Cologny

Bordering Geneva, Chêne-Bougeries, Vandœuvres, Collonge-Bellerive and Choulex, Cologny enjoys a privileged position on the Left Bank, with a direct view of the lake and the Jet d’Eau from its hillside. No SBB railway station serves the municipality, but a dense network of TPG bus and tram lines links it to Geneva and the neighbouring municipalities.

The market stands out for a very high proportion of individual ownership, with 95% of buildings and 91% of homes owned by private individuals, one of the highest rates in the canton. This ownership structure, combined with municipal taxation among the lowest in Geneva, largely explains Cologny’s lasting appeal to a demanding clientele.

In practical terms, supply remains surprisingly broad for such an exclusive municipality: 346 properties are currently for sale, a substantial volume that gives buyers genuine choice despite the high-end positioning of the local market. On the rental side, 129 properties are available, a tighter supply that reflects the essentially residential nature of the municipality, which is not geared towards renting.

History and culture

The history of Cologny

The name Cologny dates back to Roman times, before the municipality became lastingly tied to Geneva from the 16th century onwards. It owes its literary fame above all to the summer of 1816, spent at the Villa Diodati by Lord Byron, Percy Shelley and Mary Shelley, who wrote Frankenstein there. Long a farming community, the municipality gradually became a sought-after residential area, while keeping the country houses inherited from the 18th century.

Cultural heritage.

– Villa Diodati: the house where Frankenstein was written in 1816, now one of the best-known literary sites in the region.
– La Belotte pile-dwelling site: a Neolithic lakeside site, with piles dated between 1805 and 1778 BC.
– Monument to the landing of the Swiss: at Port Noir, on an enclave ceded by the City of Geneva in 1939.

Where to go out?

– Port Noir: a lakeside marina, the historic landing point of the Swiss contingents in 1814.
– Geneva Golf Club: a golf course with views over Lake Geneva.

Buy or rent

Settling in Cologny

Cologny remains above all a market of owner-occupiers rather than a rental pool, with renting being the exception rather than the norm. For the few properties available to rent, the median rent is around CHF 47 per sq m per month. The population stands out for its stability: an average age of 42.2 and 36.81% foreign residents, a profile consistent with the municipality’s residential standing rather than with rapid rental turnover.

In detail

The neighbourhoods of Cologny

In Cologny, the property market is best read area by area. The municipality is made up of several neighbourhoods and hamlets with very distinct profiles, from the village core of Frontenex to the lakefront of La Belotte. Here are the three best-documented areas for a search or a valuation in Cologny.

Frontenex

The historic heart of the municipality, crossed by the old Roman road linking Bourg-de-Four to Corsier. A residential area that concentrates most of the schools and the few shops identified, a central reference point for locating a property.

Ruth

A sector in the south-east, attached to Geneva territory by the Treaty of Turin in 1754, which then set the municipality’s definitive boundaries. Residential and historic, it retains a character distinct from the rest of Cologny.

La Belotte

A lakeside area, marked by a Neolithic archaeological site and the Port Noir marina. The most sought-after lakefront in the municipality, it logically concentrates the most coveted properties.

Demographics

Demographic profile.

Cologny had 6’149 inhabitants in 2025, over an area of 3.64 km², which corresponds to a density of about 1’647 inhabitants per km². Since 2016, the population has grown by 11.7%, notable growth for a municipality that is already largely built up and residential. Its residents, nicknamed the Colognotes, enjoy a quality of life that the municipality itself describes as elegant yet popular, with a renowned view of the Jet d’Eau and the Geneva harbour.

Sell

You are selling a property in Cologny.

Plentiful supply in a high-end market.

At present, the supply in Cologny covers profiles ranging from the town house to the large upmarket estate. This volume, higher than in municipalities of comparable size, does not remove the need for rigorous price positioning from the moment a property goes on the market, as the target clientele remains particularly attentive to the exact location, between Frontenex, Ruth and the lakefront of La Belotte. A good knowledge of the property market in Cologny remains the best guarantee of a controlled sale in this competitive context.

Municipal taxation.

Cologny applies a municipal tax rate of 25 additional centimes in 2026, unchanged since 2025 after a cut of 2 centimes compared with 2024, which places it joint first among the 45 municipalities of the canton, level with the lowest rates. This is roughly 17 to 18 centimes below the cantonal average, estimated at 42 or 43 centimes, one of the most marked tax advantages in the canton. As everywhere in Geneva, any property transaction in Cologny remains subject to Geneva cantonal taxation, which is common to the whole canton. Transfer duties are 3% of the sale price, payable by the buyer in most cases. The property profits and gains tax (IBGI) is owed by the seller where a gain is made, under a declining scale linked to the length of ownership, which can reach 50% before two years of ownership, against a minimum of 2% beyond 25 years.

The steps

The steps to selling your property

The luxury property market remains particularly active in the municipality. A property priced correctly from the outset will generally sell faster than one whose asking price is adjusted after several weeks on the market.

No-obligation property valuation

A property advisor will visit your property and assess its value based on its location, size, overall condition and current market data. You will receive a detailed, well-supported valuation with no obligation to proceed.

Property valuation analysis

Where appropriate, our in-house team of architects and engineers assesses your property’s potential, exploring opportunities for extensions, renovations or simple improvements that could increase its value before it goes on the market.

Sales strategy

Together, we determine the asking price, marketing timeline and most likely buyer profile for your property, allowing us to select the most effective marketing channels and the right pace of promotion.

Property marketing

Virtual tours, professional videos, high-resolution photography, a property brochure and a carefully crafted description, followed by promotion across our marketing channels, partner network and database of qualified buyers.

Viewings and negotiations

A dedicated property advisor arranges and oversees every viewing, screens prospective buyers and negotiates on your behalf until a final agreement is reached.

Signing at the notary's office

We handle all administrative and legal aspects of the transaction through to the signing at the notary’s office, coordinating with all parties involved.

FAQ

Frequently asked questions

Why is taxation in Cologny so advantageous?

Cologny applies a rate of 25 additional centimes, the lowest rate in the canton of Geneva, shared with a few other municipalities, which is roughly 17 to 18 centimes below the cantonal average. This tax advantage, combined with the municipality’s residential setting, largely explains why Cologny remains one of the most sought-after property markets on the Left Bank.

Is selling a detached house in Cologny a lengthy process?

With 346 properties for sale in September 2026, mostly detached houses, supply remains broad for a municipality of this standing. The time it takes to sell depends mainly on how the price is positioned from the moment the property goes on the market: a property correctly valued for its area, Frontenex, Ruth or La Belotte, generally finds a buyer faster than one priced above the local market.

How long does it take to get from Cologny to Geneva Airport?

Allow around 20 to 25 minutes by car to reach Geneva Airport from Cologny, as the municipality has no SBB railway station and no direct motorway access on its territory. This journey time is a factor to bear in mind for international buyers or families who travel frequently.

Does Cologny have many foreign residents ?

Yes, the municipality has 36.81% foreign residents, a notable proportion for a residential municipality of this standing. This diversity goes together with an average age of 42.2, consistent with a stable population profile rather than one with high turnover.
