Casalecchio di Reno, where the Reno valley opens onto Bologna
Leaving Bologna to the south-west, you are in Casalecchio before you notice: this is where the Reno valley opens onto the plain, right outside the city. The river runs through the town, with the weir (the Chiusa) and a park on the first hills on one side and residential districts on the other. It is a thoroughly urban place, with the Unipol Arena, a large shopping centre and businesses along the old Porrettana road.
Trains on the Porrettana line and the line to Vignola stop at several stations in the municipality, and city buses run into Bologna. Buyers mostly find flats in apartment blocks, plus some houses on the hills, where access, gradients and ground stability matter.
Istat, the national statistics office, counted 35,373 residents in 2023, roughly stable since 2011 (up 0.6%). Households are small, 2.02 people on average, and 26.2% of residents are over 65, above the metropolitan average of 24.8%. Foreign residents make up 11.4%, and declared incomes are above the Bologna province average.
Casalecchio is in seismic zone 3 of the Civil Protection classification, with an expected ground acceleration of about 0.165 g; within the metropolitan city, 12 municipalities, almost all in the Apennines, are in zone 2. In blocks from the 1960s and 1970s, built before current codes, it helps to know whether structural work has been done, perhaps alongside external insulation.
The Reno and the hill streams can cause trouble in heavy rain, as the floods of recent years in Emilia-Romagna have shown. The report checks flood and landslide hazard at the address, starting from the land parcel published by the Revenue Agency.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

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 179 inhabited census areas in Casalecchio di Reno. Half of the residents live in areas scoring 64 or more.
