State loan-plus-grant for modernising and repairing existing rental buildings in Bavaria — the line a co-op, Verein, Syndikat-GmbH or Stiftung uses after buying an old Mehrfamilienhaus. Recipient is the owner entity (Eigentümer, Erbbauberechtigte, Nießbraucher — BayModR Nr. 3.1); no household applicant.

  • Object: ≥3 rental flats, building ≥15 years old (≥5 years when BEG-standard measures are done); costs eligible up to 60% (75% justified) of comparable new-build cost. No flat in the building may be under Wohnungseigentum — BayModR Nr. 2 requires that “an keiner Wohnung Wohnungseigentum begründet sein” darf.
  • A WEG cannot use this line. The Wohnungseigentümergemeinschaft is excluded by the object rule above, not merely absent from the list of recipients (Nr. 3.1 names Eigentümer, Erbbauberechtigte and Nießbraucher of Mietwohngebäude). Bavaria’s separate WEG-Modernisierungsprogramm is closed, so a Bavarian Baugruppe that ended in condominium ownership has no state line for common-part energy work and falls back on kfw-261 and bafa-beg-em.
  • Loan: up to 100% of eligible costs; Zinsbindung 10/15/20 yr, 2 tilgungsfreie Jahre then 1.5% Tilgung. Rates (Stand 09.01.2026): 2.80% / 3.40% / 3.80% nominal for 10/15/20-yr Bindung.
  • Grants: Basis-Zuschuss up to €300/m² Wohnfläche + Nachhaltigkeitszuschuss up to €200/m² (needs measures in ≥3 of 5 sustainability fields).
  • Gates: rent after works must be sozialverträglich (§§ 558/559 BGB); on re-letting, a Belegungsbindung of 10 or 20 years (matching the Zinsbindung) for households within Art. 11 BayWoFG income limits with WBS; DAWI over-compensation checks for Unternehmen.
  • Apply before start at the Bewilligungsstelle (Bezirksregierung / Munich, Nürnberg, Augsburg); BayernLabo lends. A BEG EM investment grant (bafa-beg-em) may be taken alongside; one Sondertilgung up to that grant is allowed.

Use with the new-build sibling bayern-wohnungsbauprogramm-mietwohnraum; for energy-only measures compare kfw-261.
