The decree in force since 8 May reshapes the regulatory framework for Italian public and social housing. Here is what really changes for market operators.
Decree-Law no. 66 of 7 May 2026, published in Official Gazette no. 104, introduces a comprehensive package of urgent measures under the Piano Casa (Housing Plan), with the stated objective of increasing the supply of affordable housing through public, social and subsidised residential construction and urban regeneration programmes. The measure is currently before the Chamber of Deputies (Bill C. 2920) for conversion into law within 60 days of its entry into force.
The context: a structural housing emergency
The Piano Casa stems from an unsparing assessment of Italy's public housing stock. According to Federcasa data, the national ERP (public residential housing) Observatory has recorded 797,034 units, of which 61,300 are vacant and cannot be allocated due to maintenance deficiencies. A further 53,000-plus properties owned by public bodies — Municipalities, Regions, Provinces and Ministries — lie unused, while demand for affordable housing in major cities continues to grow, as documented by ANCE Brescia and the Gromia Observatory.
The three pillars of the decree
Decree-Law 66/2026 acts on three main fronts. The first concerns the recovery of the ERP stock through an extraordinary national programme for the maintenance of currently unallocable dwellings. Total funding amounts to 970 million euros, disbursed through INVITALIA as managing entity via a non-interest-bearing current account at the State Treasury, overseen by an Extraordinary Commissioner appointed by Prime Ministerial Decree and operating until 31 December 2027, as reported by Ingenio.
The second pillar is the Housing Coesione Fund, a new financial instrument established within INVIMIT SGR to support public and social residential construction. The third concerns integrated infrastructure programmes: mixed public-private operations in which at least 70% of investment must go towards subsidised housing at price or rent levels at least 33% below OMI (Revenue Agency) values, with a thirty-year restriction.
Commissioner powers and the heritage authority question
One of the most significant aspects for market operators concerns the new accelerating tools. The Extraordinary Commissioner may act by order even in derogation of statutory provisions, subject to anti-Mafia constraints, the protection of cultural and landscape heritage, and EU obligations. Commissioner orders, immediately effective and published in the Official Gazette, may bear on complex proceedings, the resolution of administrative disagreements, public tenders and the implementation of interventions, as analysed by the journal Diritto.
However, compared with the initial draft, the final text removed the fast-track lane for the Commissioner in authorisations for properties to be redeveloped, replacing it with a simplified services conference, following tensions between the Prime Minister's Office and the Ministry of Infrastructure over the role of heritage authorities, as reported by Sky TG24.
Anti-abuse measures and rent-to-buy
The decree introduces measures against potential irregularities in housing allocation: anyone found not to be entitled to an assigned property must repay the difference from market prices for the entire disputed period. Furthermore, anyone who resells the property before the scheduled deadline will be subject to specific penalties, as clarified by Sky TG24. The measure also introduces new rent-to-buy models, an instrument that has so far seen limited development in Italy.
Funding: the open question
The question of financial coverage remains open and will accompany the Piano Casa through its next phases, particularly with regard to European resources linked to the revised National Recovery and Resilience Plan (PNRR). The Fund for involuntary rent arrears for social housing confirms 22 million euros for 2026, while the 2027 allocation drops sharply from 20 million to just 2 million, as highlighted by Sky TG24.
Market impact: opportunities and risks for operators
For developers, asset management companies and institutional investors, Decree-Law 66/2026 opens up concrete operational scenarios, particularly in the area of integrated public-private programmes. The measure aims to encourage urban regeneration, demolition and reconstruction, social housing and the recovery of existing stock, limiting the consumption of greenfield land, according to the analysis by Level House. Cities under high urban pressure — Milan above all — are where the practical impact will be most significant.
The main risks for operators are twofold: parliamentary conversion, which could substantially alter the current text, and the operational complexity of the commissioner mechanisms, which will require a high level of legal and administrative oversight. For legal professionals, a demanding landscape is opening up: supporting operators in the correct use of the accelerating tools is already a priority today, as underlined by the journal Diritto.
Conclusion
The Piano Casa 2026 is the most ambitious regulatory intervention in the Italian housing market in decades. With over 10 billion euros committed, a hybrid public-private architecture and unprecedented commissioner powers, the decree reshapes the rules of the game for all players in the supply chain. The real match takes place over the next 60 days, during parliamentary conversion.
