The Mietshaeuser Syndikat: A Network Against Selling

A German network of 170-plus collectively owned housing projects that can never be sold. Founded in Freiburg in 1992 by housing activists from the autonomous left and squatter movements. Each house is a GmbH with two shareholders: the residents' association and the Syndikat, which holds one share carrying a permanent veto over any decision to sell. Financing comes from Direktkredite, direct loans from solidarity lenders at below-market rates, typically 0.5 to 2.5 percent.

The Mietshaeuser Syndikat: A Network Against Selling

What the Mietshaeuser Syndikat is, and what it does

The Mietshaeuser Syndikat is a German network of collectively owned, permanently non-speculative housing projects. Founded in Freiburg in 1992, it has grown to over 170 house projects across Germany and Austria, housing more than 1,000 people in collectively self-managed buildings that can never be sold on the private real estate market.

The Syndikat does not own the houses. That is the first thing to understand about it. Each house project is its own legal entity, a GmbH (private limited company), owned jointly by two shareholders: the house project's own residents' association, and the Mietshaeuser Syndikat association itself. The Syndikat holds one share. That share carries a veto right over any decision to sell the building. Because the Syndikat's veto right is permanent and non-negotiable, no house project can ever sell its building for private gain. The building stays collectively owned, permanently.

The problem the Syndikat addresses is the re-privatization of collectively acquired housing. A group of people can come together, raise money, buy a building, collectively manage it, and build something they are proud of. Then, fifteen years later, founding members move away, newer members have less ideological commitment, real estate values have risen significantly, and someone proposes selling. Without a structural block, the collectively built project can be dissolved by a majority vote and its value distributed to whoever happened to be a member at that point. The Syndikat's veto share makes that impossible.

Where the Syndikat came from

The Mietshaeuser Syndikat was founded in Freiburg im Breisgau in 1992 by a group of housing activists who had been part of the autonomous left and squatter movements of the 1980s. The founding group included people from the Breisach squatter scene and from prior collectively organized housing projects in Freiburg. They had watched collectively organized buildings get sold or re-privatized and wanted a legal mechanism that would make such a sale structurally impossible rather than just culturally discouraged.

The name is deliberately archaic. Syndikat is the German word for syndicate, and it carries a reference to the anarcho-syndicalist tradition: the idea that workers and residents should own and control the places where they live and work, without a state or a landlord as intermediary. The Freiburg founders were not utopian in their language but practical in their structure: they wanted a legal arrangement that would hold even if the founding generation's ideological commitment did not.

The Syndikat grew slowly through the 1990s and 2000s, then accelerated sharply after 2010 as German real estate prices rose and the urgency of non-speculative housing alternatives became more apparent to a wider audience. By 2020 there were over 130 projects; by 2024, over 170. The geographic concentration is in southwestern Germany (Freiburg, Heidelberg, Mannheim), Berlin, and other major cities, but projects exist across Germany and into Austria.

The Syndikat has explicitly resisted becoming a large institution. It employs a small staff, operates from modest offices in Freiburg, and uses a loose federated governance structure in which the house projects themselves send representatives to the Syndikat's assembly. New projects are admitted through a consultation and acceptance process: a group wanting to form a new house project works with the Syndikat over one to three years before formal admission.

How the Syndikat model works in practice

The legal structure

Each house project is organized as a GmbH. The GmbH has two shareholders: the house's Hausverein (residents' association) and the Mietshaeuser Syndikat e.V. (the registered Syndikat association). The Hausverein typically holds between 50.1% and 99% of the shares; the Syndikat holds the remainder. The Syndikat's shareholding is written into the GmbH's articles of association with a permanent veto right against any resolution to sell the building, dissolve the company, or transfer the Syndikat's share to any other entity. This veto cannot be overridden by a supermajority of the Hausverein. It is absolute.

Financing through Direktkredite

The capital to purchase a building comes from three sources: bank loans, public subsidies where available, and Direktkredite. Direktkredite are direct loans made by individual supporters at below-market interest rates, typically between 0.5% and 2.5% depending on the loan term. A supporter lends money directly to the house project's GmbH, receives a personal loan receipt, and earns a small return. The loans are subordinated to the bank loan, meaning the bank gets repaid first. Direktkredite are not insured or guaranteed by the Syndikat; they carry risk. But they are also a way for people who support the model to invest their savings in a way that is socially useful rather than purely financial.

Many Syndikat houses finance 20-40% of their purchase price through Direktkredite, the rest through bank mortgages. This makes the buildings purchasable without requiring residents to have personal equity, which is the point: the Direktkredite network democratizes access to collective building ownership.

The Solidarbeitrag

Each house project pays a monthly Solidarbeitrag (solidarity contribution) to the Syndikat, calculated as a fixed amount per square meter of living space. The Solidarbeitrag funds the Syndikat's small staff, its consultation work with new projects, and a solidarity fund that supports projects in financial difficulty. The amount is small, typically a few euros per square meter per month, but across 170-plus projects it adds up to a meaningful operating budget.

Governance and autonomy

Within the Syndikat's one structural constraint (no sale), each house project is fully autonomous. It sets its own rent levels (usually significantly below market rate), manages its own maintenance and renovations, decides on new members through its own process, and organizes its collective life however it chooses. Some houses are politically radical; some are conventional in their daily functioning except for the ownership structure. The Syndikat does not impose a common culture or political line. The anti-sale veto is the only non-negotiable element.

What the Syndikat does not do

The Syndikat is not a landlord. It does not manage buildings, collect rent, or settle disputes between residents. Each house project is responsible for its own management.

The Syndikat does not provide capital. It does not lend money to house projects or guarantee their loans. Each project has to raise its own Direktkredite and negotiate its own bank mortgage. The Syndikat provides consultation and the structural anti-sale mechanism; the financial risk stays with each project.

The Syndikat does not prevent financial failure. A house project that cannot service its mortgage can lose its building through foreclosure. The anti-sale veto prevents voluntary sale for speculative gain; it does not protect against involuntary sale through insolvency. Financial management at the house level is therefore as important as governance.

The model is deeply embedded in German law (GmbH structure, German mortgage practice, German non-profit law). Replicating it precisely in other jurisdictions requires adapting the legal structure. Groups in the UK, France, the Netherlands, and Austria have developed analogous approaches using their own legal forms, but there is no direct translation.

How to begin with a Syndikat-inspired structure

QUESTIONS TO START ASKING

Is there a Syndikat-equivalent network in your country? In Germany, the Syndikat is the obvious starting point. In Austria, the Hausprojekt Network operates on similar principles. In France, Habicoop and the cooperative d'habitants model address the same problem through a different legal route. In the UK, Radical Routes and the community land trust network both offer non-speculative housing structures.

How will you finance the building purchase? Direktkredite require a network of solidarity lenders who trust your project. Building that network takes time and relationship, not just a good pitch. Start cultivating potential lenders before you need them.

What is your group's capacity for collective governance? The Syndikat model requires residents to manage their own building, including maintenance decisions, financial management, and member admission. Groups that have not lived collectively before often underestimate this work.

How long are you prepared to work before moving in? Syndikat house projects typically take three to seven years from initial group formation to occupancy. The consultation period with the Syndikat, the building search, the financing, and the renovation all take time.

4 steps toward a Syndikat-style project in Germany:

1. Contact the Mietshaeuser Syndikat (syndikat.org) early and attend one of its regular consultation events (Beratungstreffen). The Syndikat runs regular meetings for groups at different stages of formation and provides experienced advisors who have been through the process. This consultation is free and is explicitly part of the model.
2. Build your Direktkredite network before you have a building. A house project that has identified 200,000 euros of committed Direktkredite is far more credible to a bank and to a seller than one that has not. Start the conversations with potential solidarity lenders as early as possible.
3. Form the GmbH and the Hausverein at the right moment in the process. The legal structure takes some time to set up correctly; it should be in place before you sign a purchase contract. The Syndikat's advisors can guide you on timing.
4. Plan for the consultation period. The Syndikat does not admit projects automatically. Groups work through a consultation process that can take one to three years, during which the Syndikat evaluates whether the group has the capacity to manage a collective building and whether the project is financially viable. Use this time to build your group's governance capacity.

Living examples and entry points for community builders

The Mietshaeuser Syndikat (syndikat.org) in Freiburg is the primary resource. Its website includes a list of all member projects, a description of the legal model, guidance for groups in formation, and contacts for regional consultation. It publishes an annual report and a newsletter (die Hauszeitschrift) that documents the network's development.

The first Syndikat house, Hausprojekt Hambacher Str. 24 in Freiburg, has been operating since 1994 and is the longest-running documented case. Several Berlin projects, including K77 in Prenzlauer Berg (since 2006) and others in Neukoelln and Friedrichshain, are well-documented in the German alternative housing literature.

Mietshaeuser Syndikat Austria (syndikat.at) operates under Austrian law with an equivalent structure and is the starting point for Austrian projects.

For groups outside Germany and Austria, the closest structural equivalents are: the Les Pas-Sages cooperative d'habitants model in France (described in a separate Library entry), the Radical Routes network in the UK, and the Community Land Trust model in the UK and US.

The ToGather archive does not yet include a direct interview at a Syndikat house project. This entry is grounded in public sources. An interview at a long-running Syndikat house, particularly one of the Freiburg or Berlin projects, would substantially deepen the entry.
