San Giorgio su Legnano, a town joined onto Legnano
A glance at the map explains San Giorgio su Legnano: it is joined onto Legnano, continuing its streets westwards with no countryside in between. This is the Altomilanese, the belt north-west of Milan that grew up around textile and engineering works and is now a mix of small villas, low-rise blocks of flats and industrial sheds. More than half of the municipal area is built over or otherwise sealed.
There is no station in the municipality. For Milan people take the train at Legnano, on the line to Gallarate and Varese, or join the A8 motorway, which has an exit at Legnano. The larger services, starting with the hospital, are in the neighbouring town.
At the end of 2023 there were 6,732 residents, practically the same as in 2011: the difference is 2. The estimated average age is 46.7, a little above the 45.6 of the metropolitan city of Milan, and over-65s make up 25.3% against 23.0%. Foreign residents are 10.1% and households have 2.24 members on average. Declared incomes are below the provincial average, though that figure is lifted by Milan itself.
Earthquake hazard is among the lowest in Italy. San Giorgio is in seismic zone 4 of the Civil Protection classification, along with 72 other municipalities in the province, and expected ground acceleration is about 0.039 g. In a house from the 1960s or 1970s, the energy rating, the state of the roof and the heating and electrics matter more, as do service charges and already approved works in blocks of flats.
With so much ground covered by buildings and tarmac, heavy storms can put cellars and underground garages under strain, so the report checks the official flood maps for the address. The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report goes from the address to the plot.

Earthquakes
For Italy's Civil Protection Department, San Giorgio su Legnano is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (73 of 133) are in the same zone.

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