KFW 2 residential units - however, only 1 residential unit was indicated in the building application

Hello everyone,

do you know if it is sufficient for the energy consultant of the KfW to certify that the house has 2 residential units, or does that also have to be stated in the building application?

The plans etc. will of course be adjusted and the exterior dimensions will not change! Therefore, I don't have to have the building application etc. changed, right???

Background:
At first, we did not want to convert above our garage - maybe for later.
Therefore, the building application was also submitted in such a way that the building area is used as an undeveloped attic. This is how the building application was approved.

Now we would like to completely convert that part of the building (family situation has changed).
In other words, a single-family house (180m² living space) with one residential unit (62m² living space).

Many thanks for your help.

Best regards Florian

You absolutely must apply - it is possible that the 2 residential units will not be approved for you - or you will have to provide more parking spaces. Possibly plan other emergency routes, etc. If you do not apply = illegal construction.

See KfW documents:

"Residential units are rooms within a self-contained unit intended for permanent residential purposes in residential buildings, which allow the running of a household (room, kitchen/kitchenette, and bathroom/toilet)."

And the requested representation must correspond to the truth.

Look here:
Criminal Code (StGB)
§ 264 Subsidy Fraud

(1) Whoever is punished with imprisonment of up to five years or a fine, who
1.
makes false or incomplete statements about facts relevant to the subsidy for himself or another to an authority responsible for granting a subsidy or another person or body involved in the subsidy procedure (subsidy provider), which are advantageous to him or the other,
2.
uses an item or a monetary benefit whose use is restricted by legal regulations or by the subsidy provider with regard to a subsidy contrary to the use restriction,[...]

And if plans are changed (faked), it may be a serious case, which can result in up to 10 years...

That's right.. Where there is no plaintiff, there is no judge!
