Question about the building inspection for our new extension?

Hello! I would like to have a tip. We have extended our small mining house with an annex. The architect got the approval, everything is ok. Now the annex is completely finished. I told the architect to please do the final inspection now, he came by, looked at everything, and said everything looks nice. But doesn't someone from the city have to come out and check this? Won't I get a confirmation that everything is proper? Because I hear neither from the city nor from the architect. Is it enough if the architect tells the city everything is ok, or should I call the building authority? I don't want them to come in 5 years and say I never reported the completion of the construction just because the architect didn't feel like it. Next time I will take another one. Best regards, Axel

It's been a while... I think the tax office will get in touch. You have to fill out a form to have the property tax assessed. Because the value of the property has increased, you have to pay more in property tax. At least, that's how it was for us. Regards
