The municipality

Troinex, the Salève for a horizon and the city ten minutes away.

Troinex (1256) is one of the smallest municipalities in the canton of Geneva by area, and one of the greenest. Backed against the Salève, bordered by the Drize and by France, it is organised around its village and its hamlets — Marsillon and La Maison, La Grand-Cour, Évordes. A complete countryside setting, some ten minutes from the city and a stone's throw from the Salève cable car.

The property market in Troinex is that of a villa municipality: family houses on large plots, a few village houses, very few apartments. The average price stands at around 13,800 CHF/m², up 22% since 2020 — one of the strongest rises on the Left Bank, driven by Geneva families looking for space without moving away.

On this type of property, the value gap plays out on the plot, the southern exposure towards the Salève and the quality of the renovation, far more than on the address — the municipality is too small for the hamlet's name to make the price. Rousseau 5 follows every sale recorded in Troinex and values each house individually, the only valid method in a market this size.

Market analysis

The Troinex property market: what you need to know

Troinex is a residential villa municipality at the foot of the Salève, one of the smallest in the canton of Geneva by area and one of the greenest. The housing stock consists almost exclusively of family houses on large plots and a few village houses, spread between the village and the hamlets of Marsillon, La Maison, La Grand-Cour and Évordes; apartments are rare. The 22% rise over five years, one of the strongest on the Left Bank, comes from a sought-after combination: a complete countryside setting — the Salève at the door, the Drize, the farm lanes — some ten minutes from the city centre, with the Salève cable car a few minutes away in neighbouring Veyrier. The municipality is too small for the address to make the price: on a house, it is the plot size, the exposure, the view towards the Salève and the quality of the renovation that determine the value, which makes individual valuation indispensable. The average selling time of 95 days reflects the nature of the product — a villa buyer takes their time — rather than a difficult market: correctly priced properties find their buyer. Municipal tax rate of 45 centimes, around the cantonal average.

FAQ

FAQ — Property in Troinex

15 concrete answers to the questions most often asked about Troinex

What is the price per m² in Troinex in 2026?

The average price stands at around 13,800 CHF/m², with an indicative range of 12,144 to 15,456 CHF/m². The municipality is too small to yield reliable gaps from one hamlet to the next: on a villa, it is the plot, the exposure towards the Salève and the state of the building that make the value, not the address. Every property is valued individually.

Which is the best estate agency in Troinex?

In a villa market where every property is different, it is the one that values house by house rather than at the neighbourhood average. Rousseau 5 has been a Left Bank agency since 2012: we follow every transaction recorded in Troinex, a single broker handles your file from the first meeting to signature, and the valuation is free within 48 hours, with no commitment.

How long does it take on average to sell a property in Troinex?

Around 95 days. This reflects the nature of the product — a villa buyer takes time to compare — rather than a difficult market. Correctly priced properties find their buyer; those listed too high settle in for the long haul and lose their novelty effect.

How do I get a free valuation in Troinex?

In three minutes on our online valuation page, or with a Rousseau 5 broker who visits free of charge within 48 hours. On a Troinex villa the visit is decisive: plot size, exposure, view of the Salève, the state of the outdoor areas and the extension potential weigh more than the living square metre itself.

How much is the agency commission in Troinex?

The brokerage commission is discussed according to the property, the mandate and the support expected: there is no single rate. It is only due upon the successful sale, and it is set out in writing in the mandate.

Exclusive or open mandate in Troinex — which is better?

Exclusivity is clearly preferable. In a municipality this size, a property listed by several agencies is spotted immediately and makes the seller look rushed. A single, targeted approach, addressed to the families already searching at the foot of the Salève, delivers better results.

What is the property tax situation in Troinex?

The municipality applies 45 additional centimes, around the cantonal average. On resale, Geneva's IBGI applies according to the holding period (from 50% under 2 years to 2% beyond 25 years) — often the floor rate here, as villas pass down over decades. Our net-seller simulator works it out precisely.

What are the notary fees when buying in Troinex?

Allow around 4% of the price: 3% registration duties, Land Registry fees and the notary's fees. These costs are paid on top of your equity.

Which surveys are compulsory when selling in Troinex?

An asbestos survey for any building predating 1991 — hence most of the 1960s–1980s villas and the village stock. Add the installation checks, the Land Registry extract and the plans. For a house with land, verifying plot boundaries and easements avoids bad surprises at the sale agreement.

Can you extend a villa in Troinex?

It depends on the zone and the land-use ratio already reached on the plot. In a market where the land makes most of the value, documented extension potential can change the selling price noticeably — and its absence, if discovered late, can derail a transaction. We check this point before the sale.

How does a property inheritance work in Troinex?

Taxation of the gain is deferred: the heir takes over the deceased's holding period, which almost always leads to the floor IBGI rate of 2% on a family villa. Rousseau 5 assists estates with a neutral valuation and a discreet sale.

Is it better to rent out or sell a property in Troinex?

The average gross rental yield runs around 3.2%, with near-zero vacancy. Keeping a villa in a municipality where the land never renews itself is perfectly defensible; selling captures a 22% gain over five years. A broker works through both scenarios with you.

What is an off-market sale in Troinex?

A sale without public advertising, reserved for qualified buyers. In a small municipality where every listing gets noticed, it is often the best approach: it protects the seller's confidentiality and avoids the wear of an advertisement that lingers.

What should you know about life in Troinex?

The Troinex school is within the municipality, Place de la Mairie; the assigned secondary school is Drize, in Carouge. Bus 45 serves Troinex-Mairie, central Geneva is ten minutes by car and the Salève cable car a few minutes away, in neighbouring Veyrier. Hiking, paragliding and climbing start from the doorstep — that is what brings families here.

Which municipalities border Troinex?

Veyrier to the east towards the Salève, Carouge to the north towards the city, Plan-les-Ouates to the west, Bardonnex to the south, and neighbouring France through the Croix-de-Rozon crossing. Veyrier, Carouge and Plan-les-Ouates each have their own dedicated market page.
