Price per square metre in the area: OMI price ranges explained

OMI price ranges are the minimum and maximum prices per square metre that Italy's Revenue Agency (Agenzia delle Entrate) publishes twice a year for every zone of every municipality, for buying and for renting. They tell you the price band that ordinary homes in that zone move within. The price of one particular house then depends on the floor, its condition, which way it faces and the negotiation.

What OMI price ranges are

The Property Market Observatory (Osservatorio del Mercato Immobiliare, OMI) is an office of the Revenue Agency. It divides each municipality into zones where the market behaves alike, the OMI zones, and for each one it records sale and rental prices of homes and other property. The Agency's staff start from sale deeds and rental contracts and fill in a standard form for each property. They do this in about 1,400 municipalities, where about 70% of sales take place; elsewhere, where sales are few, the figures come from the same staff's comparative valuations.

For each zone the result is a table. The rows are the property types (standard housing, economy housing, high-end housing, villas and townhouses, garages, shops, offices, industrial buildings) and the three states of repair: excellent, normal and poor. Each row has two ranges: the sale price in euros per square metre and the rent in euros per square metre per month. One of the states is marked as the most common in the zone.

The figures come out every six months. According to the Observatory's manual (in Italian), the second half of a year is published by 15 March of the following year and the first half by 15 October: the latest out at the time of writing is the second half of 2025, published on 16 March 2026. The ranges therefore lag the market by a few months.

How to find the OMI zone of an address

The official route is the OMI price lookup on the Revenue Agency's GEOPOI map, free and without registering (in Italian). From the menu choose "Ricerca" (search) and type the address, or move the map to the house, then click on the zone: a sheet opens with the zone code, its description and the prices for the latest half-year. The map covers half-years from 2016 onwards; for those from 2006 there is also a text search on the Agency's website, by province, municipality and zone.

Or type the address above: straight away, and free, you see the liveability index of the area, and the full report starts from the OMI zone the house falls in.

One thing to know. In 2024 the Agency redrew the zones of about 900 municipalities (the review it carries out every ten years), and the new boundaries apply from the second half of 2024. If you compare today's prices with those of a few years ago, check that the zone has stayed the same.

What B, C, D, E and R mean

Each zone has a code made of a letter and a number. The letter is the band (fascia), meaning where the zone sits in relation to the built-up centre: B central, C semi-central, D outer, E suburban (settlements separated from the centre, like many frazioni, the outlying villages) and R extra-urban, the countryside, also called rural. The number only tells apart zones in the same band: B1 is the first central zone, B12 the twelfth, and it does not mean one costs more than the other.

Small municipalities have few zones: of nearly 7,900 municipalities, about 5,500 have three or fewer. Milan has more than forty. Examples and details are in the article OMI zone codes B1, C2, D1, R1 explained.

Why it is a range and not the value of the house

The Agency says so plainly in its manual: OMI figures cannot replace a valuation of the individual property. The range is where the average value of homes in ordinary condition in the zone is most likely to fall. Homes of special quality and badly run-down ones are left out, and zones are drawn so that, as a rule, the maximum price is no more than 50% above the minimum for the most common type of home.

Within that range, and sometimes outside it, a particular house moves with the floor, the lift, the light and aspect, the finishes, the systems, the energy rating, a garage or cellar and the state of the building. How the square metres are measured counts too: the zone sheet says whether prices refer to gross or net floor area. For a mortgage, an inheritance or a division of property, the value comes from a formal valuation (perizia).

What the report shows

The "Price per square metre of the area" block starts from the OMI zone of the address, with its band and description, and shows the sale and rental ranges for the home types present in the zone and for each state of repair, with the most common one highlighted. Below come the comparison with the same half-year a year earlier, the trend over the years back to 2004 (with gaps where zones were redrawn), an indicative gross rental yield worked out from the zone's ranges and the number of homes sold in the last year in the municipality or the province.

They are always prices for the whole zone, with the half-year of the figure and the citation "Agenzia Entrate - OMI". The report does not estimate the value of a single flat, and we do not publish price tables by municipality on the site: how we use the data is explained in Local prices.

Frequently asked questions

Are OMI prices the prices homes actually sold for?

Not exactly. The Agency starts from sales and rentals in the zone, but where there are few it relies on its staff's valuations. The result describes the value of ordinary homes in the zone, not the average of the sales completed in a half-year.

How often are OMI prices updated?

Twice a year. The second half-year comes out by mid-March of the following year, the first by mid-October. Zone boundaries are reviewed less often, with a general review every ten years: the latest was in 2024.

Can I use OMI prices to find out what my house is worth?

For an order of magnitude, yes; for a value, no. A top-floor flat in excellent condition and a ground-floor one needing renovation sit in the same zone but not at the same price. For a figure to use with a bank or a notary you need a formal valuation.

Why are prices missing in some zones?

Some zones have very few homes or hardly any sales, and the Agency does not publish figures. It also happens in municipalities where the survey has been suspended after an earthquake, such as Norcia, Amatrice and Accumoli.
