Avusy property: a rural market across three villages and farmland

The property market in Avusy.

Avusy lies in the south-west of the canton, close to Aire-la-ville, Avully and Cartigny. This rural area, largely dominated by farmland, has a limited property market, consisting mainly of detached properties spread across the municipality's villages.

The median sale price recorded is CHF 8'205/m², one of the lowest levels in the canton, consistent with the rural, sparsely populated nature of the area. The median rent stands at CHF 34/m² per month. Over the recent period, 132 properties were marketed, 117 for sale and 15 for rent.

This moderate volume reflects a municipality where supply remains limited, driven mainly by occasional transactions rather than by a rapid turnover of the housing stock.

Types of property.

At the end of 2025, Avusy's housing stock comprised 380 to 381 residential buildings, including 325 detached houses (85.5%) and 53 to 54 apartment buildings (14.0%), the remainder being mixed-use buildings. In terms of dwellings, detached houses account for around 97.5% of the stock, compared with 2.5% for flats in apartment buildings, a split that confirms the predominantly residential, house-based character of the municipality.

Living in Avusy

In the Middle Ages, a Catholic noble family owned a castle in the hamlet of Champlong, partly destroyed during religious conflicts in 1564 and then razed in 1590. In 1602, the village of Sézegnin sent reinforcements to Geneva during the Escalade. In 1754, a treaty kept the region under Savoyard sovereignty but allowed the three villages of Avusy, Athenaz and Sézegnin to unite as a single parish. In 1815, Geneva became Swiss and the municipality joined the canton. In 1848, it separated from two neighbouring localities, giving rise to the present-day municipality of Avusy.

Avusy's neighbourhoods

The municipality of Avusy consists of three villages and one hamlet, each with its own identity, combining community life, heritage and agriculture.

Avusy

The main village is home to the parish church and hosts part of the municipality's community life.

Athenaz

This village has the primary school and a medical practice. An intergenerational housing project, together with a new village square, is currently being completed.

Sézegnin

With a rich archaeological past, including a Burgundian necropolis that no longer exists, this village also has a cultural venue in a restored former dairy.

Champlong

This hamlet preserves the ruins of a medieval castle, a reminder of the religious tensions that marked the region in the 16th century.

Demographic profile

Avusy had between 1'425 and 1'430 inhabitants in 2025, a population that has remained almost unchanged since 2015, while the canton grew by 10.8% over the same period. Between 2010 and 2023, population growth was limited to 2.2%, well below the cantonal (14.6%) and Swiss (9.4%) averages.
This demographic stability is partly explained by the agricultural use of the land, which covers 89% of the municipal area. Population density remains low, between 272 and 276 inhabitants per km² in recent years, over a total area of around 5.2 km².

Selling a property in Avusy?

Selling a property in Avusy means operating in a rural market where transaction volumes remain limited. Over the recent period, 132 properties were marketed, 117 of them for sale. The median sale price of CHF 8'205/m² reflects the agricultural, sparsely populated character of the municipality.

• Steady demand
• Standard supply
• Local buyers

Sales market dynamics

Transaction volume remains modest for a municipality of this size, with sales clearly outnumbering lettings. This low turnover, combined with the agricultural nature of the area and a limited supply of properties, suggests a stable but not very liquid market, where available properties generally find buyers without particular pressure on timescales.

Municipal taxation

The municipal additional tax rate (centimes additionnels) is 49 centimes for 2026, unchanged since 2025. This rate places Avusy among the most heavily taxed municipalities in the canton, in 4th place, well above the cantonal average of 41.4 centimes.

The stages of a sale

The high-end segment remains particularly active in the municipality. A property correctly priced from the outset generally finds a buyer more quickly than one whose price is adjusted after several weeks.
