Is it illegal for security guards not to let decoration workers into the community?

It is not illegal for security guards not to let decoration workers into the community. The property has the right to prevent decoration workers from entering the community, and the property has the right to stop and report acts that produce noise or pollute the environment within the scope of property management. However, the decoration will inevitably produce noise and pollution, and the communication between the property and the workers is not in place. Notifying the property before renovation can effectively avoid such problems.
