The report looks at the exact point: landslide and flood risk, seismic zone, price per square metre for the area, services and nearby stops.

Monterenzio, the Idice valley and Monte Bibele
Monterenzio covers a stretch of the Idice valley in the Apennines south-east of Bologna. The main village lies low beside the river at around 240 metres, and the land climbs to hill and mountain hamlets such as Pizzano and Bisano. On Monte Bibele archaeologists have excavated an Iron Age settlement and cemetery, including graves of Celtic warriors, and the finds are shown in the local museum.
To reach Bologna you head down the valley towards San Lazzaro di Savena, by car or on the regional buses. Many residents make that trip daily and chose Monterenzio for more space and greenery at lower prices than in the city. Homes range from small blocks of flats on the valley floor to scattered farmhouses on the ridges, often restored, reached by roads that need care in winter. Declared incomes are well below the high provincial average of Bologna.
Istat, the national statistics institute, counted 6,110 residents in 2023, up 4.4% since 2011. The average age is 47.3, slightly above the province, and over-65s account for 24.7%, the same as the rest of the Bologna area; households are small, 2.09 people on average, and foreign residents make up 13.3%.
The hazard to keep most in mind is landslides. The clay soils of the Bolognese Apennines move easily, so for a farmhouse or a plot on a slope read the landslide hazard maps carefully, which the report checks for the address, and ask whether there have been cracks or stabilisation works. On the valley floor the concern shifts to the Idice and its floods.
Earthquakes also count. Monterenzio is one of 12 municipalities in the province in seismic zone 2, while the other 43 are in zone 3, and the expected ground acceleration is about 0.179 g. The Revenue Agency's cadastral maps are available, and the report goes from address to plot.
Key points
- Idice valley, with Bologna reached via San Lazzaro.
- One of 12 Bologna municipalities in seismic zone 2.
- Population up 4.4% since 2011.
- Clay soils: landslide hazard must be read house by house.
Overview
Monterenzio is a municipality in the province of Bologna, in Emilia-Romagna. At the end of 2023 it had 6,110 residents, ranked 37 of 55 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Monterenzio is in seismic zone 2, a zone where strong earthquakes are possible. Only 12 of 55 municipalities in the province are in zone 2.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.179 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.
For anyone buying in Monterenzio, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
Population
Compared with the 2011 census, the resident population has grown by 4.4%. The estimated average age is 47 years, in line with the province. 25% of residents are over 65 (the regional figure is 25%). Foreign residents make up 13.3% of the population. On average, a household has 2.1 members.

Monterenzio is in climate zone E, with 2,490 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 235 metres above sea level.

Radon and contaminated sites
Monterenzio is not among the radon priority areas designated by the Regione Emilia-Romagna in 2026. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.
Official databases list no contaminated sites in Monterenzio.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Monterenzio: 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
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 64 inhabited census areas in Monterenzio. Half of the residents live in areas scoring 57 or more.
