I left my old appartement 2 months ago, I just received the regulation regarding the charges, rent, repairs and security deposit. As the title mention it, there were some costs due to cleaning of floors, sink and stuff like that for 95€. So be it. I don't know why but I wanted to check who issued the bill.
I looked up the registration number (SIRET) and found that his line of work was "Organisation de foires, salons professionnels et congrès" which you could roughly translate to the organisation of trade fairs, professional exhibitions and congresses. On paper it doesn't really seem like someone with the expertise to issue a bill for repairs in an appartment but I'm no expert in the law department either.
So I'm wondering if anyone who has the ability to issue bills can issue one regarding the matter at hands, appartment repairs.
For the information I live in France and I did my research but couldn't find anything regarding any legislation imposing some kind of craftsman to estimate the repairs.
