One regime, several jurisdictions. How Europe codified, over more than a century, housing as a service of general interest with limited profitability, non-tradability and full reinvestment. And how Portugal can replicate the same principle without dedicated legislation, through contract.

Limited-profit housing is the English-language designation for an intermediate housing category: neither free market, nor social assistance. It refers to a set of operators, public or private, that own and manage housing stock under three structural restrictions: the return on invested capital is limited by law or by statute; the assets are non-tradable or subject to restricted circulation; and operating surpluses are fully reinvested in new stock, maintenance, or rent reduction.
The category differs from classical social housing, addressed to households in need and financed by direct public subsidy, and from cooperative housing, in which property is collectively owned by the residents themselves. Limited-profit housing typically addresses the salaried middle class, operates at real cost, and finances itself through a combination of equity, subsidised debt and public guarantees. Rent is indexed to production and operating cost, not market value, and the housing unit is not a commodity tradable in the common real-estate circuit.
In short: profit exists, but it is finite, regulated and returned to the sector itself. This is the operational difference from affordable housing as practised in Portugal, frequently a temporary financial instrument rather than a permanent patrimonial category.
The most influential contemporary formulation of the regime is Austrian. The Wohnungsgemeinnützigkeitsgesetz, known by the abbreviation WGG and approved in 1979, codified the status of Austria's not-for-profit housing builders (gemeinnützige Bauvereinigungen). The law imposes a cap on equity remuneration, an obligation to reinvest surpluses in housing activity, restrictions on selling units, cost control by the sectoral regulator, and an obligation of public accountability.
The result, after four decades, is the most studied housing system in Europe. In Vienna, the combination of direct municipal stock (Gemeindebauten) and the WGG builders' stock covers a very significant share of the city's total housing, with estimates ranging between 40% and 60% depending on the definition used. Rents are regulated by Mietpreisbindung, a cost-indexation mechanism that decouples rent from speculative market pressure. The empirical consequence is one of Europe's lowest average housing effort rates, and the persistence of the middle class in the city centre.
For the interested reader, we recommend the reports of the International Union of Tenants and the comparative studies of Housing Europe, the federation of European non-profit operators.
The Dutch case is older. The Woningwet of 1901, the housing law approved in the context of the early-20th-century hygienist reforms, established the framework for the woningcorporaties, private-law housing associations of public-utility character. These operators today own and manage around 2.4 million homes, a figure that represents a significant share of the Dutch housing stock and the largest non-profit per-capita stock in Western Europe.
The system is regulated by the Autoriteit woningcorporaties (Aw), an independent public authority that supervises governance, solvency and fulfilment of social mission. Between 2010 and 2015, the sector went through an identity crisis marked by episodes of financialisation, speculative derivatives and mission drift by some operators. The response was a counter-reform that re-tightened the perimeter of authorised activity and reinforced the accounting separation between social activity and market activity.
The Dutch case shows two things relevant for Portugal: that a limited-profit regime can scale to systemic dimension; and that, without permanent institutional vigilance, it is vulnerable to financial capture. It is a precedent that informs the governance architecture of Fundação Âncora (in Portuguese).
Germany articulates three types of operators. The Wohnungsgenossenschaften, housing cooperatives with a tradition dating back to the 19th century, are member-resident associations in which property is collective and use is individual. The public Wohnungsbaugesellschaften are municipal or state-owned companies, of which GEWOBAG and Howoge in Berlin, or SAGA in Hamburg, are paradigmatic examples. There are also large-scale private operators, such as Vonovia or LEG, today listed on the stock exchange and operating with market-return logic.
Between 1940 and 1990, Germany had its own Wohnungsgemeinnützigkeitsgesetz, a tax regime that exempted public-utility operators from corporate tax in exchange for restrictions analogous to the Austrian ones. The law was repealed in 1990 in a movement of liberalisation that many analysts today consider precipitous. The current German debate revolves around the reintroduction of a modern limited-profit regime, designated Neue Wohngemeinnützigkeit, with legislative proposals under parliamentary discussion.
For Fundação Âncora, the German case is instructive regarding the articulation between operators of different typologies under a common regime, the logic at the basis of the operator framework-contract (in Portuguese).
The United Kingdom has Europe's oldest philanthropic tradition in this domain. The Peabody Trust, founded in London in 1862 by the donation of George Peabody, is considered the historical prototype of modern housing associations. For more than a century, these associations operated as small-scale charitable entities. Professionalisation and expansion came mainly with the Housing Act of 1988, which redirected public financing from direct municipal construction to acquisition and management by associations.
Today, the sector regulated by the Regulator of Social Housing covers an estimated 2.7 million homes, a relevant share of the rental stock. The combination of private financing with purpose-regulation and governance control brings the British model, in financial structure, close to what Fundação Âncora proposes to replicate in Portugal: institutional capital channelled into assets with permanent use restrictions, managed by professionalised operators under independent oversight.
Portugal has never codified limited-profit housing as an autonomous legal category. The Affordable Rental System Regime (RSAA) and its successors (RAA, PAA, and related instruments) are tax-incentive programmes for landlords, conditioned on rent caps for limited periods. After the term, the unit returns to the free market. They are cyclical instruments, not patrimonial categories.
The Controlled-Cost Housing (HCC) regime, in turn, regulates the construction phase (maximum costs per square metre, areas and finishes), but does not prescribe the subsequent operating regime. A unit built as HCC can be freely commercialised on the market, within the applicable legal parameters.
The Portuguese cooperative housing sector, organised around FENACHE and operators such as COOHABITA, has remained at modest scale. The instruments of the 2019 Basic Housing Law and of the Programme for Housing Access Support (1.º Direito) address social housing in the strict sense. The intermediate space, housing for the salaried middle class with permanent patrimonial restrictions, is empty in Portugal. It is this gap that the architecture proposed by Fundação Âncora intends to fill.
In the absence of dedicated legislation, Fundação Âncora, in formal constitution, proposes to replicate the regime by contract. The central instrument is an operator framework-contract (in Portuguese) signed between the Foundation and each partner operator, whether IPSS social-solidarity institutions, holy houses of mercy, housing cooperatives or commercial companies. The contract binds the operator to the system's five non-negotiable principles: non-tradability of assets, full reinvestment of surpluses, active neighbourhood (planned social mix), cost-indexed rent, and excellence and durability of the built fabric.
Assets held directly by the Foundation (in Portuguese) are subject to statutory non-tradability, written into the foundation's own articles. Assets held by partner operators are subject to contractual non-tradability, enforceable against third-party acquirers through reversion clauses and registrable rights of pre-emption. The legal-economic effect is functionally equivalent to that of the Austrian WGG, even if the normative basis differs.
Financing, in multi-year structuring, combines the foundation's own equity, Notas de Impacto Social subscribed by institutional investors with structurally capped returns, direct EIB financing, CEB debt covered by InvestEU and European Investment Fund guarantees, and Portugal 2030 funds. Rent paid by residents is calculated on the real cost of operation, maintenance and amortisation, with no extraction component. In parallel, surface-right contracts with municipalities (in Portuguese) on public land are foreseen, a mechanism that reduces production cost and territorially anchors the project.
The inaugural programme, in multi-year structuring, targets around €200 million mobilised over five years, allocated to approximately 1,000 homes distributed across six to seven municipalities. These figures are declared objectives, not execution, and are subject to the foundation's effective constitution and confirmation of financial partners.
For the professional middle class, with monthly gross incomes between €1,200 and €2,500, the limited-profit regime means, on the execution horizon, the possibility of accessing dignified housing in urban centres with cost-indexed rent, without competing directly with foreign investment, real-estate funds or short-term tourism rentals. The families (in Portuguese) page details the eligible household profile.
For municipalities, the model offers a vehicle to mobilise public land for permanent affordable housing without ceding land ownership and with no direct budgetary expense. The surface-right contract (in Portuguese) reverts the land to the municipality at the end of the term, while maintaining public control over use throughout.
For institutional investors, pension funds, insurers, family offices with impact mandates, the Notas de Impacto Social offer a stable-yield asset, decorrelated from the speculative real-estate cycle, with measurable and auditable social-impact dimension.
For IPSS, holy houses, cooperatives and commercial companies wishing to operate housing stock under this regime, joining as a partner operator (in Portuguese) opens access to structured financing, a stable contractual framework, and a system of operational best-practice sharing with European counterparts.
For the private real-estate sector (BTR developers, builders, architecture practices, real-estate managers), Fundação Âncora does not compete: it contracts, co-develops and acquires services. More than 70% of the inaugural programme's capital flows to the Portuguese productive fabric. Cooperation modes are detailed in the For the Sector (in Portuguese) page.
No. Social housing, in the Portuguese legal sense, addresses households in proven economic need and is financed by direct public subsidy, with means-tested rent. Limited-profit housing addresses the salaried middle class with regular incomes, operates at real cost and is financed by a combination of private capital and public bonification. The two categories are complementary, not substitutes.
Yes, and in every European country where it exists it coexists with the private market regime. The Austrian and Dutch experience suggests that a significant limited-profit sector has a moderating effect on the adjacent free market by removing demand pressure.
In the model proposed by Fundação Âncora, oversight is multi-layered. The foundation itself, as a private regulator, audits contractual compliance by partner operators. The foundation's accounts are subject to independent external audit and annual publication. Subscribers of the Notas de Impacto Social have contractual information rights. Above all of this, the public oversight applicable to foundations in Portugal is exercised by the competent authority.
Yes, in principle. Contractual replication of limited-profit housing depends mainly on three conditions: existence of a foundation legal form (or equivalent) with statutory non-tradability; existence of asset-protection instruments enforceable against third parties (land registry, rights of pre-emption, reversion); and availability of patient institutional capital. The three conditions are present in most European jurisdictions.
The German Neue Wohngemeinnützigkeit is a legislative proposal to reintroduce a dedicated tax regime for public-utility operators. Fundação Âncora's model does not depend on legislative approval to begin: it operates within the existing legal framework, by contract and by statute. Should Portugal in the future codify a regime analogous to the Austrian WGG, the foundation's architecture is designed to integrate into that regime without operational disruption.
