Whether the warehouse on the second floor of the clothing store on the first floor will be fined depends on local laws and policies. According to relevant information, generally speaking, the nature of use, building structure, fire safety and other factors of commercial buildings will affect whether they comply with the provisions of relevant laws and regulations, so it is necessary to judge whether there are violations according to specific circumstances. If the business scope of the clothing store on the first floor is inconsistent with the nature of the use of the warehouse on the second floor, or there are potential safety hazards in the use of the warehouse on the second floor, it may be considered illegal by the relevant departments, and it may be required to make rectification. If it is not rectified, it may be fined.
