The way to report the opening of a barbecue shop under a residential building depends on the specific behavior violated, and it is generally divided into the following situations:

1. If the barbecue stall downstairs is disturbed by noise during the rest period of residents, the parties concerned can negotiate with the stall owner. If there is a noise pollution problem, several representatives representing all residents should negotiate with the stall owner and ask the stall owner to stop business within a specified time. Secondly, you can call the police, because this kind of noise pollution is also an act of disturbing normal social order and belongs to the jurisdiction of the police, so you can call the local police station and let the police coordinate and deal with it;

2. If the smoke from the barbecue shop downstairs is too big and the influence is too great, you can complain to the community neighborhood committee, the environmental sanitation administrative department or the local industrial and commercial administrative department.
