Sennori, the Romangia hills between Sassari and the sea

From Sennori you can see the sea. The town sits on the hills of the Romangia area, north of Sassari, almost joined to Sorso, and the two share the same landscape of vineyards and olive groves running down to the Gulf of Asinara. This is where Moscato di Sorso-Sennori is made, a sweet wine with protected designation of origin, and much of the countryside is still farmed.

Sassari is the city people rely on for work, hospital and university, a short drive away; the coast is a few minutes off. The town is built on a slope: the old centre has tightly packed houses, often in need of renovation and with steep internal stairs, while the newer areas on the edges have detached houses. If you are buying outside the centre, check access, utility connections and building permits for any rural property.

The population is falling: 6,856 residents in 2023, down 7.0% since 2011. It is younger than the province, though, with 24.4% aged over 65 against 26.6%. Foreign residents are very few, 1.2%, and average declared incomes are below the provincial level.

Earthquakes are not a major worry: all 66 municipalities in the province of Sassari are in seismic zone 4, the lowest in Italy's national classification, and the expected ground acceleration is about 0.050 g. In older houses, what matters most is damp in walls and foundations, the state of the roof and insulation against summer heat.

On the slope facing the sea, the report checks landslide hazard and ground gradient for the specific address, together with the flood maps along the small streams.

Overview

Sennori is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 6,856 residents, among the most populous in the province (7 of 66).

Earthquakes

For Italy's Civil Protection Department, Sennori is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 66 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 7.0%. The estimated average age is 47 years, in line with the province. 24% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.2% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Sennori declared an average taxable income of 17,617 euros, below the provincial average (21,361 euros). The Italian average is 24,895 euros.

Sennori is in climate zone D, with 1,442 heating degree days: heating may be switched on from 1 November to 15 April, for up to 12 hours a day. The same table puts the town hall at 277 metres above sea level.

How built-up it is

Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslide and flood hazard changes from one street to the next even within Sennori: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Liveability area by area
