Gerenzano, a Ferrovie Nord stop next to Saronno

Gerenzano sits in the south-eastern corner of the province of Varese, bordering Saronno and the province of Como, within the ring of towns that have almost merged into one another around Saronno, north of Milan. It is a town on the dry upper plain, with a small centre, many detached houses and a large industrial area.

Its strong point for anyone working in Milan is the railway. Gerenzano has a stop on the Ferrovie Nord network, and Saronno, one of the main hubs of Trenord, the Lombardy regional rail operator, is a few minutes away; public transport data list 2 train and bus lines in the municipality. Junctions on the A9 motorway towards Como and Milan are a few kilometres off. The report measures the distance to the stop from each address, and on foot it can vary a lot from one street to the next.

The population is growing. Istat, the national statistics office, counted 10,872 residents in 2023, up 4.4% on 2011. The estimated average age is 44.5, lower than the provincial 46.5, and over-65s are 21.4% against 24.7%. Foreign residents make up 10.4%. Average declared incomes are a little above the provincial average.

Earthquakes are a minor issue: the whole province of Varese is in seismic zone 4, the lowest in the national classification, with an expected acceleration of about 0.040 g. For buyers, the energy rating and insulation matter more, since winters are cold and heating bills add up, as does how close a house is to the industrial sheds, worth checking on a map before viewing.

The land is heavily built up and public green space per resident is a little below the provincial average. The Revenue Agency (Agenzia delle Entrate) publishes Gerenzano's cadastral maps and the report traces each address to its plot; flood hazard, linked to the streams and channels of this plain, is also checked address by address.

Key points

  • Ferrovie Nord stop, a few minutes from Saronno.
  • 10,872 residents, up 4.4% since 2011.

Overview

Gerenzano is a municipality in the province of Varese, in Lombardia. At the end of 2023 it had 10,872 residents, ranked 18 of 136 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Gerenzano is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 136 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.040 g, a low 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 grown by 4.4%. The estimated average age is 44 years, lower than the province average (46). 21% of residents are over 65 (the regional figure is 24%). Foreign residents make up 10.4% of the population. On average, a household has 2.3 members.

Gerenzano is in climate zone E, with 2,437 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 226 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Gerenzano has 5 schools and 3 pharmacies. The Overture Maps data also lists 5 grocery shops and supermarkets, 4 healthcare facilities, 6 sports facilities and 2 parks and green areas.

Radon and contaminated sites

Gerenzano is not among the radon priority areas designated by the Regione Lombardia in 2023. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list one contaminated site, or site still under investigation, in Gerenzano, and 5 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Gerenzano: 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.

Land registry

The cadastral maps for Gerenzano are public: from the address the report finds the sheet and parcel number.

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 55 inhabited census areas in Gerenzano. Half of the residents live in areas scoring 72 or more.
