Thuringia’s main rental line (Richtlinie zur Förderung des bezahlbaren Mietwohnungsbaus 2026–2030, ThürWoFG). Ministry TMDI, Bewilligungsstelle Thüringer Aufbaubank (TAB). Nummer 1.3 c names “die Schaffung von Anreizen für gemeinschaftliches Wohnen” as an aim.

  • Instrument: interest-free Baudarlehen plus optional direct Zuschüsse that reduce the loan; together ≤ 80 % of eligible cost. A grant-only application is impossible.
  • Term: 30 years, up to 35 with a 15-year longer Bindung; zinsfrei throughout.
  • Eigenleistung: ≥ 20 % — cash, paid materials, self-performed planning (§ 8 II. BV), land paid from own funds. Eigenkapital earns a notional 1–2 % in the Wirtschaftlichkeit.
  • Bindung: ≥ 20 years (25 for Modernisierung/Sanierung). +10 years earns a 20 % Zuschuss, +15 years 35 % (Neubau) or 30 % (other) of the max Fördersatz.
  • Rent: €6.80/m² in Erfurt, Jena, Weimar; €6.15 in towns over 20,000; €5.60 elsewhere; +€0.20/m² every two years, capped by the ortsübliche Vergleichsmiete.
  • Applicant: natürliche Personen und juristische Personen des privaten und öffentlichen Rechts owning or controlling the site — an eG, e.V., GmbH/gGmbH or Stiftung in its own name. Whether an eGbR qualifies is an open question (not a fact); see mopeg-egbr.
  • Scale gate: at least three bound flats; eligible spend over €7,500.
  • Path: Programmanmeldung to TAB first (2026 deadline 17 September 2026; then 31 October or 31 March), ministry admits, only then does TAB invite the application. The Bürgschaftsausschuss must also admit the loan to the guarantee contingent.
  • Combinability: Kumulierung expressly allowed (Städtebauförderung, Dorferneuerung); no double funding of the same cost.

Further Zuschüsse: 5 % for renewable building materials, 5 % for over-fulfilling BEG minimums, 10 % for accessible or wheelchair flats beyond the compulsory share (≥ 20 % barrier-free, of which 20 % R-Standard), 10 % of extra cost for barrier reduction in the Bestand. Cost ceilings €2,300/m² Bauwerkskosten (€2,500 barrier-free, €2,700 R-Standard, €2,100 Modernisierung), indexed by TLS Preisindizes — the Richtlinie’s worked example yields €3,300/m².

Mixing funded, unfunded and non-disturbing commercial units in one building is allowed. Letting to a Wohngemeinschaft is decided case by case: the residents must count as a Haushalt in wohnraumförderungsrecht terms, with WBS and Wohnflächen rules met — a real constraint on cluster-flat cohousing here. The 2021 Innenstadtstabilisierungsprogramm (ISSP), which funded “Miet- und Genossenschaftswohnungen”, is superseded by this Richtlinie.
