Office figures: BNP Paribas Real Estate, regional offices review Q2 2026: vacancy rate 4.7% at the end of June 2026, the lowest of the eight regional markets measured; the supply available within a year rose 4% on a year while new supply fell 29%. 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.
There is no open list of empty buildings or homes: the national vacant-homes file (LOVAC) is restricted to public authorities.

Check any building in Toulouse: could it become homes, and could the EHC model work there?
Where empty offices, the right zoning and a working neighbourhood come together — and what could go wrong.
The most conversions in the city, among them the former postal site on avenue des Minimes, and seven brownfields along the canal.
Risk: Large sites go to developers by permit before anyone else hears of them.
Old offices and hotels near the main station are being converted: 11 permits since 2013.
Risk: The station-quarter project raises values; conversions are mostly private.
Office blocks by the ring road, one empty since 2018 and now being converted (Tersud), and four brownfields.
Risk: Car-oriented business parks; conversions need whole buildings and large investors.
Timber-framed and brick buildings that the City closes by urgent safety order when floors fail — some stay closed for years.
Risk: Small co-owned buildings: buying needs every owner, and the City's orders are not published as a list.
Who controls the space, and what a housing cooperative can actually do with them.
The City's unsafe-buildings service (Immeuble menaçant ruine, Direction de la Protection des Populations) closes buildings by order and can do the works at the owners' cost. A co-owned building closed for years is a candidate for purchase: a co-op can approach the syndic with a works plan.
The City picks developers for buildings it no longer needs by call for projects, as for the Caserne Jacques Vion, where the brief mixed homes for sale, assisted ownership and social rent. A co-op can bid with a partner for the next one.
Action Logement subsidiaries buy converted offices in bulk for young workers and social, intermediate and assisted-ownership homes (Tersud). A co-op can propose a share of such a conversion or a partnership on a smaller building.
Decisions, auctions and closures that change what becomes available, and when.
4.7% at the end of June 2026; the supply available within a year rose 4% while new supply fell 29%.
Urgent safety order forbidding access, habitation and use after floors sagged.
The former fire station, closed in 2025, becomes about 120 homes, a restaurant, coworking and a park.
About 13,000 m² of offices empty since 2018 → 232 homes.
Cerema's LOVAC file (tax records) counts 26,176 private homes vacant on 1 January 2025, 5,182 of them for two years or more, against 275,212 private homes. The 2026 edition changed method, so it runs above earlier years; the address-level file goes only to local authorities.
