According to the provisions of relevant laws and regulations, property associations usually have the authority and responsibility to manage maintenance materials. According to China's current property law and property management regulations, the property association, as an organization, is responsible for managing some repairs and maintenance of the property, including the management of maintenance materials.

Property associations can establish and maintain maintenance data files, including relevant documents, contracts, drawings and maintenance records. The purpose of maintenance data management is to keep the records of maintenance process and history for future reference, avoid repeated maintenance, reduce maintenance costs and provide a strong basis for the quality and safety of maintenance projects.

However, the specific scope of power and responsibility may vary from region to region and specific circumstances. In some places, there may be specific regulations. For example, the maintenance information management of property associations needs the approval of the owners' meeting or owners' committee. Therefore, the specific situation may need to refer to local laws, regulations and policies.

In short, property associations can usually participate in the management of maintenance materials, but the specific authority and scope of responsibility need to be determined according to local laws, regulations and policies. It is suggested that you contact relevant local departments or professionals for more accurate information and guidance.
