Chianni, a hill village in inland Pisa

Chianni is a hill village in the countryside inland from Pisa, in the Valdera area, surrounded by woods, olive groves and wheat fields. The village centre sits on high ground, with stone houses and narrow lanes; around it lie farms and scattered farmhouses, many of them restored over the years.

People who buy here usually want quiet and countryside and accept a few extra kilometres for services: for big supermarkets, secondary schools and work they head to the towns of the Valdera, while Pisa and Livorno are a drive away. For an isolated farmhouse, check access, water supply, drainage and the internet connection, none of which can be taken for granted in the country. Average declared incomes are below the provincial average.

There are 1,321 residents (2023), 9.3% fewer than in 2011. The average age, 51.5, is higher than in the province of Pisa (46.9), and over-65s are 32.6%. Foreign residents account for 9.7%.

All 37 municipalities in the province are in seismic zone 3. In Chianni the expected ground acceleration in the built-up area is 0.140 g. In the village's stone houses and the farmhouses, ask whether the roof and floors have been worked on and whether the permits are in order.

On Tuscan hills, clay soils can shift. The report finds the land parcel on the Revenue Agency maps and checks the official landslide and flood maps for that address.
