National framework for public-land direct affordable/social rental or use-right construction/rehabilitation. Art 25 lists public entities, specified mixed companies and social housing providers; ordinary cooperative registration does not prove provider eligibility. ≥50 years registered rental/use destination and permanent protection. Rural sale is possible in municipalities/nuclei≤10,000, with a reasoned territorial agreement possibly extending to≤20,000.
Art 28€1,000/m²/70% baseline, max 85 m² counted/home; advanced industrialisation or formally declared stressed market €1,100/75%, both €1,200/80%; specified assistive-tech uplift up to €8,000/home. Territorial commission may modify terms. Initial rent/use ceiling €8/m², prescribed annex/rent-indexation rules; resident income criteria apply.
Requires territorial call or justified direct award and monitoring agreement/viability memorandum. A private cohousing group normally approaches the public/provider partner rather than treating this public promotion channel as its own direct grant.
