Grezzago, a growing village east of Milan

Grezzago is one of the smallest municipalities in the Milan metropolitan area: by population it ranks 122 out of 133. It lies on the plain east of the city, towards the river Adda and the Trezzo area, where fields alternate with housing estates and business parks. Land take is very high, as in much of the Milan hinterland.

In recent years the village has drawn families looking for a larger home at lower prices than in the towns closer to Milan. Most buildings are recent: terraced houses, low blocks and a few restored farm courtyards in the centre. People get around mainly by car, with the A4 motorway not far away; anyone using trains or the metro has to reach stations in nearby towns.

The growth shows in the figures: Istat, the national statistics office, counted 3,171 residents in 2023, up 11.6% since 2011. It is a young place, with an average age of 42.8 against 45.6 for the metropolitan area and over-65s at 18.2%. Foreign nationals make up 12.2%. Average incomes are below the provincial level, which includes Milan itself.

Earthquakes carry little weight: seismic zone 3, expected ground acceleration 0.088 g. For a new home, check the energy rating, the quality of the windows and the service charges; for a restored courtyard building, check the permits and planning compliance. The report also checks the flood maps for the address.

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