This is because according to the Fire Protection Law and the Property Management Regulations, any building must meet the fire safety requirements. Therefore, it is very necessary for the property company to carry out fire-fighting renovation of the apartment, and the quality deposit is charged to ensure the normal operation and maintenance of the fire-fighting facilities after the renovation.

If you don't agree to pay the quality deposit, you can raise a written objection to the property management company, but you need to explain the reasons and provide the support of relevant laws and regulations. If the property company still insists on paying the quality deposit, you can complain to the local fire department or the property supervision department and seek the help of relevant institutions to solve the problem.

In addition, in order to protect your rights and interests, you can ask the property management company to provide specific plans for the renovation of fire-fighting facilities, maintenance and management plans for fire-fighting facilities, specific uses of quality deposit and other materials to ensure that the requirements of the property management company are reasonable and legal.

In a word, it is legal to collect quality deposit for apartment building property, but before paying quality deposit, you need to know the specific details and requirements and safeguard your rights and interests.
