Where can I complain about the unqualified fire protection of residential property?

Complain to the fire department. If the residential property fire is unqualified, you can complain to the fire department, because the fire department is responsible for supervising and managing the fire control work, including inspecting and supervising the fire control facilities of the property company. If there is a problem with the fire protection facilities of the property company, the fire department will ask the property company to take measures to eliminate potential safety hazards and carry out rectification and maintenance. If the property company ignores it or the rectification effect is not good, the fire department will take corresponding administrative punishment measures to ensure fire safety, so it can complain to the fire department.
