Procedure descriptions
Housing promotion - applying for modernisation funding for rental housing stock
Companies and private individuals can receive funding for the following projects under the current state housing promotion programme:
- energy-efficient refurbishment or
- age-appropriate conversion of rented accommodation.
There are two funding lines to choose from:
- Socially oriented modernisation funding for rental housing stock - without justification of rent and occupancy commitments
- Social modernisation funding for existing rental housing - with justification of rent and occupancy commitments
Socially oriented modernisation funding for existing rental housing - without justification of rent and occupancy commitments
No new rent and occupancy commitments are established in this funding line.
Funding is provided in the form of loans and, in some cases, grants. The loans are subsidised for a limited period of time.
The subsidised housing must be available as rental housing for a certain period of time; during this time, rent increases due to modernisation are also restricted.
Social modernisation funding for existing rental housing - with the establishment of rent and occupancy commitments
The above-mentioned projects are subsidised with the establishment of rent and occupancy commitments in the rental housing stock.
Funding is provided exclusively in the form of grants.
