In Riom, an apartment sells on average for 1 836 €/m², according to the sales registered by notaries and published in DVF data, the French notarised sales database, for the year 2025. This benchmark rests on 104 apartment sales, a pace of around 91 transactions a year over the last two years, which makes it a solid average for a town of this size. The flat supply is split between the old buildings of the historic centre, enclosed by its boulevards, and more recent residential blocks built on the outskirts and around the station. The house remains the most active market in volume, with 219 sales over 2024 and 2025, driven by the housing estates of the outlying districts and of the neighbouring municipalities of the Limagne.

The Riom market moves in step with the Clermont-Ferrand conurbation, the leading employment area of the department. The proximity of Clermont-Ferrand, linked by rail and motorway, feeds demand from households looking for larger floor areas for a comparable budget. The conversion of the tobacco factory, with the arrival of a Hermès workshop employing more than 270 people, brings skilled industrial jobs to the heart of the town. These factors support a steady volume of sales, without the tensions seen in the most sought-after municipalities of the metropolis.
Energy performance is becoming a decisive sorting criterion. Dwellings rated F or G, numerous in the old housing stock, suffer discounts on resale and are gradually being withdrawn from the rental market by the Climate and Resilience Act. In the protected centre, renovations have to reconcile insulation with respect for the façades, which lengthens lead times and raises the cost of works. For an owner who is selling, a property already renovated or accompanied by costed quotes generally sells faster than a dwelling whose upgrade cost remains unknown.
Riom sits below Clermont-Ferrand and Vichy, and at a level very close to Romagnat, a residential municipality in the south of the metropolis.
Riom grew up where two landscapes meet, the farming plain of the Limagne to the east and the first slopes of the chaîne des Puys to the west, on the banks of the Ambène. Its political destiny was decided in the 13th century: in 1213 the town became the capital of the Terre d'Auvergne, then that of the duchy of Auvergne until 1531. This role as a seat of power explains the density of its medieval and Renaissance heritage, rare for a town of fewer than twenty thousand inhabitants.
Duke Jean de Berry, brother of King Charles V, left a lasting mark on the town at the end of the 14th century. He had the ducal palace rebuilt and the Sainte-Chapelle raised between 1384 and 1403; the tour de l'Horloge dates from 1391 and the church of Notre-Dame-du-Marthuret from 1308. In the 16th century, the notables of the seneschalty built residences such as the maison des Consuls and the hôtel Guymoneau. The judicial vocation continued afterwards: a sub-prefecture since 1801, Riom received the court of appeal in 1804, and it was in its law courts that the Vichy regime opened the Riom trial in 1942 against leaders of the Popular Front.
The 19th century added an industrial dimension. The tobacco factory, built between 1877 and 1883 near the station, was the largest in France in the 1920s, before production was transferred in 1975 to a new plant in the Varenne neighbourhood. The historic site was converted in stages: housing and offices moved in, then a Hermès leather goods workshop opened there in 2024. The old centre, a protected conservation area since 13 February 1967, and the Ville d'art et d'histoire label obtained in 1985 now frame the way the buildings evolve.
Riom has 18 820 inhabitants and works as a support town for the Clermont-Ferrand conurbation, while keeping its own administrative, judicial and commercial functions. Two types of housing coexist: the old housing of the centre, made up of town buildings and mansions divided into apartments, and a more recent stock of houses and small residential blocks on the slopes and in the outlying districts. Buyers are often working people employed in Clermont-Ferrand looking for a more contained budget, families attracted by a house with a garden, and investors targeting the small units of the centre. The presence of the Riom Limagne et Volcans community authority and of the law courts sustains a demand for housing linked to public-sector employment.
For an apartment, the local benchmark is 1 836 €/m², calculated from the deeds of sale actually signed and published in DVF data. This level reflects an average between old dwellings in the centre, sometimes in need of renovation, and more recent residential blocks. An apartment with a lift, parking or a balcony can sit well above it, while a poorly insulated old dwelling will sell below. The Immover valuation tool lets you refine this benchmark according to the features of your property.
Yes. The old centre and its boulevards form a remarkable heritage site, a former protected conservation area created in 1967, governed by a safeguarding and enhancement plan. Work on façades, joinery, roofs and even some interior fittings is subject there to the opinion of the Architectes des Bâtiments de France, the state heritage architects. Before a purchase with a renovation project, check with the town hall planning department to find out the requirements that apply to the building.
In number of sales, the house wins: 219 transactions over 2024 and 2025, against around 91 apartment sales a year. Per square metre, houses sell on average for around 2 292 €/m², a little above apartments, because they often include a plot and are located in more recent residential neighbourhoods. The gap remains moderate, which is why this page uses the apartment as its reference price.
Riom - Châtel-Guyon station, on the line from Paris to Clermont-Ferrand, is served by TER regional trains towards Clermont and by Intercités trains from Paris-Bercy. By road, junction 13 of the A71-A89 motorway puts the town around fifteen kilometres from the centre of Clermont-Ferrand. This double connection explains why some of the buyers come from the neighbouring metropolis.
A good part of the buildings in the centre predates the 20th century, with thick walls of volcanic stone and narrow stairwells. The energy performance diagnosis, the condition of the roof and the presence of efficient heating weigh heavily on the price. For an apartment in an old co-ownership building, read the minutes of the general meetings to anticipate façade restoration or compliance works.
