Duties of a carport manufacturer

Hi everyone.

The following situation: House is built (in Cuxhaven), carport is chosen and contract signed. By the way, the price is regularly almost €13,000.
The carport is a kit and will have space for two cars and a workshop on a total of 50sqm. The manufacturer company is Biber Carport from Munich and the contract includes a clause in case of a negative building permit, so that the contract could be terminated if the permit is not approved. I have already paid a deposit.
So far, so good.
When figuring out what needs to be done for the building permit, the building authority said the application must be signed by a "draft author". That is either an architect or a master craftsman – whoever designed it. And of course they need a drawing of the carport.
That is clear too.
So I approached the company, who then said they do not have such a person in-house, but externally. And they would now have to ask if he could sign it, because sometimes further liabilities are tied to these signatures, which they could not fulfill remotely, for example.
If, for example, the draft author were automatically assigned a construction supervision obligation. They want over €500 extra for the drawing.
I can even understand the cost for the drawing since my carport is custom-made. As for the liabilities in the building permit, I cannot find anything in the form.
There is merely a paragraph about the draft author, name, company, etc., and that was it.

They took a lot of time for the review, so after more than four weeks I asked if they were now able to sign the application. Otherwise, I would like to exercise my right of reservation.
I only accepted Corona as an excuse to a very limited extent, because the review externally happens anyway via forwarding an email and I sent that one week before the curfew started in Bavaria.

Now, after more than five weeks after receiving the form, they replied that they needed more time and mentioned Corona and everything. Also, there was never talk of a building permit service and I can only assert the reservation if I can show a rejected building permit.
Funny – how is that supposed to work if they don’t give me the signature I need...?!

Long story short: Can anyone answer what the standard duties of a manufacturer in such matters are? In my view, of course, this belongs to the product. Meanwhile, they act almost as if this were a comfort service similar to a registration service when buying a car. They probably haven’t quite understood what this is about yet, but that can be clarified again. Nevertheless: What belongs to the normal product scope in such cases and what is an extra service?
Even though I can understand the additional cost for the drawing, I think one should be made aware of this when purchasing, especially since the size means that a building permit must be applied for in every federal state and thus a drawing is needed.

Looking forward to your answers.

Hello, we have also been messing around with our sauna for ages. In Hessen, you also need a building application, or it can be required. Here, only an authorized signatory can do it and has to submit the full package. We once had it shown to us at the building authority during an open consultation hour. I also asked the provider if they have someone, gladly for an extra charge, to assist with it. For me, it is self-evident that it always means an additional cost. Also drawings that go beyond the offer / the order. Otherwise, the company would be a bad businessman just producing costs. Draftsmen etc. also want to be paid.

So once again: what the building authority wants to see is simply that the person who professionally designed it also documents it. What is the extra work about? It’s like buying a car from VW and then having everything individually inspected again at the TÜV and paying an engineer to certify it... Edit: or did you also pay extra for your house construction for the architect to put his name on it?

That is comparing apples to oranges. You want the carport manufacturer to sign off on a building application without costs. You do realize that he is liable, for example, for the foundation?

You do know that he is liable for, for example, the ground?

Wrong. There is a separate construction manager who must be appointed for the installation, foundation, etc.

Wrong, the authority wants a signed building application. And that can only come from an authorized person. You already know who that is. It is your duty to obtain this signature. And the company is also right about the rejected building application and the associated right of withdrawal. Get the signature, pay for it, and have the thing delivered.
