Office figures: No Monaco office vacancy figure was found in any source we could open; the office-market reports that surfaced cover the Île-de-France and Luxembourg, not the Principality. Map built 2026-10-09.
Every building a record says stands empty, one point per building: filter by type, size and how sure the evidence is, and open one to see who says so. “Opportunities” switches to the co-op lens: public land, conversion potential and projects already under way, every source as its own layer.
No vacancy register or vacancy figure for Monaco was found. The press report on the latest census (Monaco Tribune, 21 May 2026) gives 22,577 dwellings and the State's 19.4% share but no vacant count; earlier census reports counted vacant dwellings, but the Government's PDFs (the 2016 census report, the 2023 housing study that reports State flats temporarily unoccupied) timed out or were refused, and the statistics office's site (imsee.mc) answers our requests with a 403 'Request Rejected', so no vacancy figure is quoted.

Check any building in Monaco: could it become homes, and could the EHC model work there?
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. Leerstandsmelder reports join the list when they sit in a large non-residential building and a second source agrees.
Where empty offices, the right zoning and a working neighbourhood come together — and what could go wrong.
A five-level, 150-metre building on the former Portier roundabout stands as a shell with no confirmed tenant; the State says it remains committed to it.
Risk: A State-backed, operator-led brief on a prime waterfront site; the interior layout waits for a tenant, and no floor area or owner structure is published.
The Mairie lets vacated commercial premises from its communal estate by call for applications; the former Habitat store was one.
Risk: Commercial rents (€305,000 a year for 497.5 m²) and single floors rather than whole buildings.
Who controls the space, and what a housing cooperative can actually do with them.
Offers communal commercial premises by public call for applications, with a fixed term and rent (the former Habitat store: seven years, €305,000 a year). A co-operative can watch the calls and apply for space for a community or housing-related use; the rents are commercial and the units are floors, not buildings.
The State holds 19.4% of the dwellings (about 38% of those in Fontvieille) and stays committed to the unlet Portier building. A co-operative's route is as a partner of the Government on State-held or State-backed buildings; Monaco has no open disposal list.
Decisions, auctions and closures that change what becomes available, and when.
The latest census shows 22,577 dwellings, up 1.8% in a year; the State owns 19.4% of the stock, nearly 38% in Fontvieille against 1.1% in Larvotto.
The five-level building is structurally close to completion with a bare interior; the State remains committed and talks with other operators are believed to be under way.
Second-floor premises of 497.5 m² on Avenue Saint-Charles, closed since 30 November 2023, offered on a seven-year occupancy.
