Office figures: CBRE — about 1.2 million m² of class A and B offices in Zagreb, 2% empty in Q2 2026 (vacant area = stock × rate). Homes: our economic model’s conversion engine. 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.
The City's empty-premises list has no coordinates: 144 of its 149 addresses are placed through the City's own house-number layer (one has no house number; 18 underpass kiosks are left off). It lists premises, not buildings — only four whole buildings.
0 empty buildings · colour = type, dark ring = confirmed
Check any building in Zagreb: 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.
Most of the City's empty premises that it calls unfit are here — courtyard buildings and cellars behind the street blocks, several weakened by the 2020 earthquakes.
Risk: Many units are small and under restitution claims; heritage protection and shared ownership slow whole-building work.
Two former industrial sites among the City's five strategic regeneration projects, next to the centre and the main station.
Risk: Neither site has an adopted plan yet, and railway land at Gredelj involves the State railways.
The City's own affordable-rent building: about 300 flats for affordable and social rent, due in the first half of 2027, with a second building of about 150 planned.
Risk: New build, not reuse — and the City builds it itself.
Who controls the space, and what a housing cooperative can actually do with them.
Owns and publishes 262 empty business premises and lets them by public tender. A co-op could bid for a whole empty building (Vitezićeva 57, Vrapčanska 116) or ask for the unfit courtyard buildings on a long lease in return for repair.
Since April 2026 the City lets its flats at income-based rents (12–24% of household income) from a priority list; a co-op could offer to run renovated City buildings under the same rules.
Adopted 21 April 2026: affordable housing is rent or instalments of at most 30% of net income; local governments must adopt housing programmes, provide land and co-finance building — the frame a co-op proposal to the City would use.
The audit told cities to publish and update their lists of empty premises and to analyse how to bring them back into use — an argument for asking the City to open its unfit premises to non-profit reuse.
Decisions, auctions and closures that change what becomes available, and when.
The government's 2025 report counts 2,174 new requests in the City of Zagreb in 2025, five years after the earthquake.
The City opened a call to rent its flats at 12–24% of household income.
Parliament passed the act 79 to 1 with 38 abstentions.
The State Audit Office found 651 unfit premises among 9,228 held by 23 cities and asked them to publish and update vacant lists.
The City cites Ministry data of about 55,000 empty flats in Zagreb — more than 80,000 judging by electricity and water use.
Of 8,875 buildings inspected after the 22 March 2020 earthquake, 587 were unusable and 2,534 temporarily unusable.
