OMI

The Observatory divides each municipality into OMI zones, areas where the property market is similar. The zone code shows the band: B central, C semi-central, D outskirts, E suburban, R rural, followed by a number (for example B1 or D3).

Small municipalities have few zones and large ones many: of almost 7,900 municipalities about 5,500 have three at most, while Milan has more than forty. The boundaries are reviewed every ten years; the latest review, in 2024, redrew the zones of about 900 municipalities.

For each zone and half-year it publishes a price range per square metre, to buy and to rent, broken down by type of property (standard homes, lower-cost homes, garages, shops and others) and by state of repair. The figures come out a few months late and the required credit is "Agenzia delle Entrate - OMI".

The price ranges are only a rough guide and do not replace a valuation by a qualified valuer (perito): the price of a home depends on floor, aspect, finishes and actual condition. In the report you will find the range for the address's zone and how it has changed over the years.

How to find the zone of an address is explained in Price per square metre in the area: OMI price ranges explained, the codes with examples in OMI zone codes B1, C2, D1, R1, and how to use the zone's prices to estimate a home in Property value in Italy: how to work it out.
