Is it legal for the property company to limit the access card to one year? What department should I complain to?

Whether it is legal for property companies to restrict access cards for one year depends on relevant laws and regulations and local policies. Generally speaking, the property management company has the right to manage the traffic and safety of the community, including the authorization and use period of the access card. However, if the term of the access card is too short or unreasonable, it may infringe on the rights and interests of the owners.

If you think that the practice of the property company is illegal or unreasonable, you can complain to the relevant property management supervision department or property association. These departments are usually responsible for supervising the behavior of property companies and resolving disputes between owners and property companies. In addition, you can also reflect the problems to the owners' committee or the property service center and seek a solution through consultation.

When making a complaint, you can provide relevant evidence and documents, such as the use record of the access card, the notice or contract of the property management company, etc. At the same time, you can also consult a lawyer or legal adviser to better safeguard your rights and interests.
