Milan keeps a public register of 146 privately owned disused buildings whose owners must start a recovery or face demolition orders, and the City is offering its own land on 90-year surface rights for affordable rented homes — with cooperatives explicitly invited. Offices are tight in the centre, but the older stock on the periphery stands empty more often.

Office figures: Savills, H1 2026 — 852,000 m² of offices available in Milan, a 9.2% vacancy rate (3.6% for grade A); stock of about 9.26 million m² derived from the two. JLL put vacancy at 9.6% and BNP Paribas RE at 9.3% for the same period.. Homes: our economic model’s conversion engine. Map built 2026-10-06.

Where to look first
Buildings with evidence that they stand empty — a second source agrees, a public record names them, or we have checked them — ranked by a score you can read: co-op scale, daylight depth, a station nearby, a zone that allows homes, affordable land and an open route in. Checked buildings carry their result; nobody has visited them on site yet.

Districts where conversion makes sense
Where empty offices, the right zoning and a working neighbourhood come together — and what could go wrong.
Bovisa, Dergano and Villapizzone (north-west)
The densest cluster on the disused-buildings register, next to the Farini yard and the Bovisa university campus, with a City plot offered for affordable rent on Via Bovisasca.
32 of the 146 art. 40 bis buildings sit in the Villapizzone–Cagnola–Boldinasco, Dergano, Bovisa and Affori districts
City land at Via Bovisasca 18 (1,838 m²) offered on a 90-year surface right
Scalo Farini covers 468,301 m² next door
Risk: Most listed buildings are former workshops and depots, so expect remediation and partial rebuilding rather than straight conversion.
Who controls the space, and what a housing cooperative can actually do with them.
Allocation rule
Comune di Milano — Piano straordinario per la casa accessibile
The City grants its land on a 90-year surface right at €1/m² for homes let at no more than €90/m² a year. Three calls (Ex Palasharp, San Romanello, Bovisasca) take bids until 26 October 2026, and social cooperatives, non-profits and consortia may bid. Twenty-one City sites are in the plan, so watch for the next round.
Owners of the 146 listed buildings must file a recovery plan within the legal deadline or face a demolition order and lose the volume bonuses. That pressure makes some of them ready to sell or to partner — approach the owners of the smaller residential and office buildings.
About 2,500 City homes managed by MM need renovation before they can be let, and ALER has some 3,400 empty units. The 'Move in San Siro' call (February 2026) gave 44 renovated ALER flats on Via Ricciarelli to an operator for young workers and students — a model a cooperative can bid into for whole buildings.
Comune di Milano — Direzione Demanio e Patrimonio (confiscated property)
Flats and shops confiscated from organised crime are assigned to non-profits and social cooperatives for social use. The June 2026 list has about 30 units marked as waiting for the next call and 19 in a call under way.
573 state buildings in Milan, 144 of them in the disposable category that can be sold or let. Four buildings at the Annibaldi barracks are listed as unused. Ask the regional office about leases or concessions for buildings leaving government use.
The rail group's property arm is selling the Farini and San Cristoforo yards, where the masterplan reserves 30% of homes for social or affordable rent. Those homes need operators — a cooperative can partner with the buyer for a building.
Affordable-housing land calls extended to 26 October
Second extension for Ex Palasharp, San Romanello and Bovisasca after operators called the €90/m² rent cap too rigid; earlier rounds drew a bid only for Via Demostene.

What this radar cannot see yet
No open aerial imagery: the City's 2024 orthophoto and the AGEA orthophotos on the Lombardy geoportal are copyright, view-only, so building cards carry no aerial close-up.
The City's main website and the PGT site block automated access, so calls, disposal plans and council papers have to be read by hand.
The art. 40 bis register names buildings but not owners, floor area or vacancy dates; the 2014–2017 survey is out of date and is used only to corroborate.
The municipal property list dates from 2019 and has no vacancy flag; the empty MM and ALER homes (about 2,500 and 3,400) are not published by address.
The confiscated-property list has no coordinates, and the City's regeneration-projects map withholds geometry, so neither can be drawn.
Office vacancy is only published as headline rates by brokers; there is no building-level or district-level open data.
